The feedback after exhibition

Photos from the exhibition site



Completed aspects

Working under these conditions was a unique experience. The exhibition allows us to show our concept in the expected environment.

We must always pay attention to whether the audience's attention is placed in the place being displayed. Basically, the audience's attention is following the rhythm of the display.

Unfinished aspects

There are also some unfinished aspects. The audience is not satisfied with the exploratory nature of the collection system.

In terms of exploration of the collection system, I hoped to add more items to make the game more exploratory, and Zhuoran was concerned that too many game elements would cause teenagers to overindulge in games, which would not be consistent with the original intention of assisting with housework. After some negotiation, we decided to keep limited items in the collection system. Although the characteristics of teenagers and the exploratory aspect of the game were taken into consideration at the same time, in fact, both sides did not get the ideal result.

The audience also reflects that the interface can be understood directly, for example, some hints can be added to the interface to let users understand the dynamics. For example, the number of hits can be displayed on the top of the monster's head, allowing players to understand their own score status in real-time.

Some audience feedback on why the play interface is not an AR interface. AR cameras should be used instead of ordinary cameras in the scene.

Some game players report that the difficulty of the game is too high and can be appropriately reduced. They may give up the game after losing the ball again and again. The excessive difficulty will affect their enthusiasm for the game.

Based on the feedback, we finally separated the game into three modes: collection, rank, and start.

Summary of my work

  1. Collision sound in the start section
  2. Monster switch

In the start part, I designed three monster styles, and each monster was designed with five hygienic states. When the player cleans a monster completely, it counts down 3 seconds and loads another monster.

  1. rank system
  2. collection system

Prototype demo

Feedback intended to acquire in the exhibition

1.Effect of online exhibition

We need to observe whether the online exhibition can achieve the effect of traditional exhibition;

Whether they can clearly understand the expression of concept;

Whether the process of arranging the playback of the device allows users to clearly understand the interaction of the prototype and the .

2.Audience reaction

We need to figure out whether the prototype attractive enough to the audience;

Whether the interface ashestic in start /collection/rank scene is attractive enough for the audience's attention;

Whether the rank interface is enough to allow users to simply and directly understand its functions and functions to be expressed.

By testing the previous envisaged solution, just fix the phone to the mop and use the gyroscope in the user's mobile phone to sense the mop's movement. This method is indeed feasible. The determined solution is to use the mobile phone as a racket on the mop, and the user still perceives the game scene through google cardboard.

Corresponding work

1.The appearance of the monster

In order to make users more motivated to play the game, apart from the system, I optimized the monster mode in PvE mode based on user feedback.

Previously, I determine to provide multiple monster appearances for users to choose, however, after user testing, it proves that the multiple monster appearances not only cannot motivate users, but also increased the interaction difficulty of AR games. Therefore, I drop the plan.

As an alternative, I design the process of the monster gradually getting clean under the hit of the water ball. Through the monster's gradually clean appearance, players can clearly perceive that their labor is effective. This sense of accomplishment will provide players with the motivation to continue playing.

In detail, the monster has five stages. The general process is from dirty to clean. Not only did the monster's brightness become brighter, but it also had fewer mud spots. Also, the expression of the monster will also change in this process, gradually changing from the initial crazy expression to the final happy smile.

Imgur Imgur Imgur Imgur Imgur


The five different states of the monster are achieved by switching five pictures. In this process, I mainly used the Renderer function to switch pictures.

When the ball hits Figure 1 10 times, Figure 1 disappears and Figure 2 appears;

when the ball hits Figure 2 20 times, Figure 2 disappears and Figure 3 appears;

when the ball hits Figure 3 30times, Figure 3 disappears Four appears;

when the ball hits Figure 4 40times, Figure 4 disappears and Figure 5 appears.

The process from Figure 1 to Figure 5 is not a single process, but it occurs cyclically according to housework activities. In this way, the player will not face the embarrassing situation that the housework is completed but there is no monster to fight.


Strictly speaking, the word disappears is not accurate. All pictures do not disappear but become invisible because there must be a "rigidbody" to detect the number of collisions. All collisions occur on invisible figure1.

Work has done

During this week, we consider another form to realize the project. However, this is a failed attempt.

Original concept:

Due to the fact that the google glasses used in AR may hinder people ’s actions and housework. In addition, the Vuforia is not so sensitive. It is a little bit slow to recognize the target image. It may not be consistent with the concept that we want to promote housework.

Failed(new) concept:

If we use the projector, people may not need to bring Google cardboard, and their horizons will be wider. Therefore, we try the previous plan: use the projector to show the virtual ball. Firstly, we install Arduino's radar module on the tool, then let it recognize the virtual ball projected by the projector.

Here is the projector made by us.


When we project the picture on the wall at a close distance, the picture is clear enough for users to use.


However, when the projector is far away from the wall , the picture will be blurred.


Moreover, when the light becomes strong, the picture nearly cannot show on the wall and the game can not run. But it is not totally a fail trial. The Arduino part can be saved to make up with the previous pure AR game mode.

Compromise solution:

After failing to use the projector, we spent some time observing the methods of mopping that users often use, and then optimizing our interaction based on these common methods. The Arduino's radar module could install on the tool or the wall.

In addition, we plan to put the mobile phone on the pole of the mop so that the camera of the mobile phone can recognize the picture on the floor.

Collection & Achievement system

This is the part I am responsible for. In this mode, because users need to explore things, so they still need to wear google cardboard. However, I met up with some troubles in converting real-time scene to VR dual screen mode because the user can just see the three-dimensional picture through the form of the dual-screen. I keep looking for a way to solve it and I will communicate it with tutors on Tuesday.

Base on the feedback, another point of change is that I set the achievement system before/after the game because getting props in a fierce game is a very impractical operation. Using objects on the ground as the target image will also be replaced by other images.

In detail, the chair will be changed into a row of seasoning jars/bottles because they are not on the ground and more related to the rank.


Yifan Wu - Mon 18 May 2020, 7:09 pm


During this week, we critique each other on miro. We got some useful and practical feedback and inspired by some works. I will continue to optimize the work by this feedback.

Change log base on the critique

The critiques I received:
  1. Why people of different ages and genders do not like to do housework.
  2. Have you considered the safety of each space? In addition to the kitchen, other spaces may also have some valuable and fragile items. How to ensure that these items are not touched during the game is a question worth thinking about.
  3. Consider whether using games to do housework will affect the quality of housework. For example, if the user sweeps the ground in a game, will there still be some unswept ground at the end of the game?
  4. The use method is a little complicated. Please consider how to make this product easier for users to learn.
  5. The voice stays at the same tone the entire time and doesn’t fluctuate when you move onto a new topic.
  6. Could you somehow make an avatar for each player?
  7. We recommend that it may increase the motivation to use the product is a daily mission system like other mobile games.
  8. Mention what features of the concept and prototype you have contributed before introducing the prototype.
  9. How your work is related to/ contribute to the deeper exploration of the team domain is unclear.
  10. For users who have never used your system or similar systems before, they might not able to correctly interact with your system
The corresponding solutions:
  1. Do more research on why people do not like to do housework on different ages and genders.
  2. Plan a safe area in advance, and just set the target images in this zone.

Prompt the user to check in advance whether there are dangerous objects in the selected area before cleaning.

·PvP mode: the main zone should be considered because it is more fierce than the PvE mode. Empty space should be planned in advance to let people prevent bumps.

·PvE mode:This area is safer than PvP mode because the players do not need to move too much. Its solution will be the same as the PvP mode.

·Colelction system:Some objects that are easy to move or sharp need to be deleted. For example, unstable chairs need to be replaced with safer sofas and cups with shoe cabinets (to be determined). Try to select large stable targets as target images.

  1. Each game only selects a part of the area to ensure the cleaning efficiency as much as possible.
  2. Try to let users use only one operation to achieve their goals. For example, when changing the shape of the ball, change it directly, no longer set confirmation operation.
  3. In the next record, my voice will be more emotional and change the tone according to the content.
  4. Avatar is acceptable, but consider the complexity of the game operation and uploading target pictures is too troublesome. We will preset multiple avatars in advance, each randomly generated in the game. This will not only enrich the gameplay but also make the player feel that the game is not too complicated.
  5. The daily mission system is a good idea, I have considered it, but it is too complicated to be suitable for the AR game. In addition, I think that daily tasks could make players resist the game, so I set up that the player only needs to log in every day to get rewards.
  6. Actually I have marked it in the video by words, but I will use voice to emphasize it next time.
  7. I think I have mentioned it clearly in my report. I focus on continuous motivation about doing housework. In detail, I mainly work on the collection system of the game and a part of the PvP game. These two areas are interconnected and contain each other. More elements of PvP would be mentioned in the next report.
  8. Since this is an exploratory AR game, especially the collection system, it is good for players to have some unknowns, but we will also provide some beginner's guide before the game, and then they just need to touch the objects in the first game. In the next games, they will be very familiar with the meaning of related game item locks.

User research

During this week, and completed the rest of user research, adjust the AR function, and the individual report.

Affinity diagram

I have extracted some information from interviews, probes, and questionnaires. Then I generated the infinity diagram. From this picture, we can see the motivation and disincentive of the participants clearly. Based on these points, we can utilize the motivation and avoid the disincentive in our design. For example, we find that target users generally lack the motivation to do housework for some reason, such as tired of repeated housework, uneven division of labor or feel lonely when doing alone, and the continuity of his motivation is low.

We use the PVP mode to increase competitiveness. In this mode, the person who wins will indulge in a sense of superiority, and the person who loses will want to win back again so that the player has the motivation to continue playing.

Some participants feel lonely when doing housework alone, so the game needs a cooperation mode, which is the PvE mode of fighting monsters in cooperation. The monster will be clean when players win the game. Some participants "like the feeling of making things clean", which just fits their psychology.

In addition, we integrate all of the existing systems into the collection system. This system will be mentioned in My focus part.


Interaction plan

We generated three interaction structures: PvP interaction structure, PvE interaction structure, and the collection system interaction structure.

My focus is on the collection system. When the player blocks the virtual button, enter the next level of the menu, such as product detail / Ball appearance/sound options.

All of the elements are hidden in some objects at home. When the camera scans the object, they will get game items connected with the object. For example, when they scan the watch, they will get an accelerator. They can press the detail button to the next menu and view the details.

I also use a similar method to cope with appearance and sound props.

Imgur Imgur

AR function

All AR elements are based on the principle of identifying the target pictures and then presenting the virtual image in the interface.

Star and finish the game

Based on this principle, we set the user to start and end the game through gestures and standing positions.

Start the game

The start function has two modes: PvP and PvE.

When users stand separately, they start PvP mode.

When users stand in a row, they start PvE mode.

Imgur Imgur
Finish the game

When two users show the same thumb gesture, the game is over.


My focus


As I mentioned above, I focus on the collection system.

This collection system can greatly increase the exploratory nature of the game and reduce the dependence on indoor space. Players can also explore together to solve the psychology of feeling lonely when they are unaccompanied. These categories can be achieved by exploring objects in the home, simplifying the game The form meets the needs of "game should not affect me too much".

When players find hidden objects, they will have a sense of achievement, which will provide them with continuous motivation. In addition, players have high requirements for sound and visual effects, so I let players collect sound and item appearance through the collection system. For example, when the player scans the golf ball, he will get the option to change the appearance of the ball to it.

During this week, I completed the work I planned last week. The most thing I do is to continue the task last week, especially the part of the user research.

User research



From figure 1, we find out that more than half of the teenagers of the interviewee's family do not have enough motivation to join in the housework. Therefore, we need to attract the attention of teenagers. To achieve this point, we need to create some elements they are curious about. From the data in the interview below, we find out that they are curious about PVP elements and good sound effects. In addition, because some parts of children do not like too much physical movement, we will not set some scenes which could need too much movement. For example, the ball should not show too far away from the children so that they do not need to move too far to catch the ball. This can also reduce the risk that they bump into things around them.

In the part of couples, they could be limited by space, so the movement limitation could follow the requirements of the children's group.



We interview two groups of families. The first group of the family consists of four people, parents, big sister, and little brother.

Here are the general questions of the interviews:

  1. Who spends more time doing housework? Why?
  2. Will you join in the housework? Why would you? Why not?
  3. How do you feel when no one helps you?
  4. What do you think of playing while doing housework? Be specific.


  1. I nearly do not do housework at home because I am always busy working. To be honest, my wife does the most housework because her work schedule is more flexible.
  2. I would wash dishes and clean the floor on weekends because my wife is so hard, I want to help her share the pressure.
  3. Because I just do the housework on weekends and I can finish it quickly, I think it is relaxed. Maybe it is because my wife cleans the floor on weekdays, so I do not need to spend too much effort to clean up on the weekend.
  4. I think there can be because this is a rare time to spend time having fun with my family. To be specific, I think the game should not affect me too much in housework.


  1. It is me definitely. My daughter will also help me to do something like mopping the floor. My husband is busy with his work and my son is addicted to video games, so they nearly do not do any housework.
  2. I will join the housework because the others would not do too much if I do not do it. In addition, I do not want to see the mess at home.
  3. I will feel very happy. My daughter would help me do something when she is at home. Although she cannot help much, I still feel very happy because she cares about me.
  4. I can it could be accepted if it can be played if it's a multiplayer game. I think it cannot move too much, it must be safe, and I worry that my family will bump into something around them.

Big sister:

  1. It is the mother. I could do more than my father and brother. Father always does not at home, so mother and I are responsible for all the housework on weekdays. My brother is always busy with his video games.
  2. I think I should help my mother share housework; she is too hard to undertake all housework. But I could not do housework for too long, because too long physical work will make me feel exhausted. I will help the mother to do a part of it, as much as possible.
  3. I have no feeling because I do not do too much. But if my father and brother can take part in, I think it could be finished more quickly.
  4. I think it must be fun. But I do not want to exercise too much, because the housework itself is tired enough. If there are enough people, the intensity can be increased.

Little brother:

  1. My mother. She is the manager of the family. Father will help her on weekends, my sister would also do some part of the housework.
  2. I would not join in the housework because it is boring. It really cannot arouse my interest. But I will clean my own room every few days. I cannot stand playing games in a messy environment.
  3. I do not feel anything, because it is proper to clean my own room.
  4. It is a great idea to make it a game. But it should be interesting enough, otherwise, I may not have the motivation to continue playing. It should have some PVP elements so that I can show them my game level. In addition, the sound effect should be good. I would be stupid if we play the game at home without voice or just a bad voice.
  5. Who spends more time doing housework? Why?
  6. Will you join in the housework? Why would you? Why not?
  7. How do you feel when no one helps you?
  8. What do you think of playing while doing housework? Be specific.


  1. We do the housework together. Strictly speaking, she does more than me because she is responsible for cooking. It is her job and I do not have an opportunity to join her.
  2. Yes, absolutely. I like to live in a tidy environment. It will keep me in a good mood.
  3. I think this does not exist in our lives, because we will consciously organize housework. But it could be more efficient if someone can help me the incorrect way.
  4. I think there should be an appropriate process. If the process is not appropriate, the efficiency of doing the housework will not be guaranteed. In addition, it is best to work together with two people to have a certain degree of competitiveness, otherwise, it will be too dull. In the end, the action of the game cannot be too large, because the single apartment we live in is not too big.


  1. I think it is me because I am responsible for cooking every day. We almost divide the other housework.
  2. Sure. I like to be busy with my husband. It is the bond of our family relationship. In addition, both of us like tidying up, so I will not refuse to join in the housework.
  3. I think it would be a little lonely if my husband did not accompany me to do housework.
  4. I think it would be interesting. We like playing video games together, so if the game is designed for us, the characteristics of PVP should be strong enough. In addition, if this game can be played for a long time, our housework may be more interesting

Infinity diagram

We conclude a part of the reply from the questionnaire, probe, and interview. We divide them into two categories generally. One of them is motivation and another one is the disincentive. We want to adopt the view from the motivation and avoid the situation in disincentive.


To do

The affinity diagram will be finished next week and the core function will be realized next week. The report and the video will also be completed in time.

Reflection of the previous work

Last week, we finally determined to adopt AR rather than a combination of AR and Arduino. This decision was approved by our teammate and tutors. Due to the fact that it would be not convenient to hold the mobile phone when doing housework, we accept the idea that put the mobile phone into the google cardboard so that players can free both of their hands when they doing the housework. We have bought two google cardboards and it is on delivery. The experience of the game would be better than before if players wear them.

User research

During this week, we have got some feedback from the interviewees previously. The feedback is composed of the questionnaire, interview, and the probe.


From figure 2 in the questionnaire, we can see that more than half of the interviewees need to distribute most of their attention when they cook. Therefore, it can infer that people will not have time to play games when they are cooking. This part would be deleted and the final housework tasks are mopping, sweeping, and washing clothes.

It also shows that most people choose level 3 attention when they do the housework, therefore, the game set when doing the housework should not be too complicated.

From figure 4, we can see that most people like listening to music when doing housework. We should meet the preference of the majority, so we need to make the sound effects a little more exciting.

From figur 7, we can see that most people feel that the visual effect is also an importatnt part of the game, so we decide to combine it with sound effect. Different sound effects correspond to different visual effects. For example, in low difficulty, the sound is longer and the virtual ball stays longer; in high difficulty, the sound is more rapid and the virtual ball stays shorter.
















We interviewed two groups of families. One group is the family consisted of four people, another one is the couple. We choose these two groups because they could have a strong contrast. This would be helpful for us to understand the changes caused by the number of people involved in housework.

Related records will be uploaded after sorting.


We accept the form of a table to implement a probe. The interviewees would fill in the form in a short time every day. As shown on the table, it will record the emotion, event, and the situation of doing housework. The feedback on this part has not got entirely. But the family which is consisted of four people seems to do more housework than the couple.



Due to the fact that I used Arduino before and have not learned how to do AR games, I'm still learned how to build the game in Unity. The codes of the game will be uploaded afterward.

To do

  1. The analysis of the interview and probe will be completed in two days.
  2. The skeleton of the code would be formed next week.
  3. Further analysis of the questionnaire and extract user need from it.

Work have done

On studio this week, we form our insights on miro.


In addition, we assigned the work of the team project, did some background research on the application, the article submitted the report. The thing I responsible for is to enhance the competitiveness and continuity of the game. I analyze in the direction of motivation and designed points and reward system to solve the problem.

During the teamwork next, I hope I can contribute to the graphic design and programming in our project.

I want to search for some projects which are similar to our project, but it is quite hard. We just got something useful about game design and did some research about the target audience.


During the workshop, we reviewed the basic usage of Arduino (Lights flashing). Due to the fact that I have studied DECO7230, it is an easy job for me. The most thing I want to mention is that we solved a big problem which worried us for a long time. Capturing the movement of the visual ball from the projector is not quite practical and we cannot find some projects which are similar to our project. We cannot figure out some way to link projector, bats, and Arduino. At first, I planned to use a mobile phone to substitute the real projector. In detail, we can use the WIFI kit of Arduino and link it to the mobile phone (projector). However, the visual ball still cannot be captured.

So, we ask the problem in the workshop. Steven suggests us to use AR to substitute the projector.

The visual ball shows on the screen of the mobile phone, we need to move it by touching and sliding on the screen. Therefore, we need to transfer the signal of hitting the ball to touching the screen.

But if we do like this, the player needs to notice the small screen of the mobile phones when they [lay the game, which is not convenient for them to observe the surrounding. The ideal situation we think is that the player wears the AR glasses and observe the situation from the screen. In this situation, the player does not need to capture the mobile phone or take the trouble to observe it, but due to the technical problem, we are not able to design such equipment. Therefore, we are possible to make some concessions to realize our project.

Work to do

This table is the general plane for the whole project.


The major problem now is that we don't know how to use the tool to capture the virtual ball projected by the projector, so we prepare to use the method mentioned above. Therefore, we need to figure out how to transfer the signal of hitting the ball to the signal of touching the screen. At first sight, we still need to use the WIFI kit of Arduino to realize it, so the first thing we need to do is trying the WIFI kit. If it doesn’t work, we could make a concession again: wire to substitute wireless.


Yifan Wu - Sun 5 April 2020, 10:25 pm

Based on the previous task framework, I keep doing my background research and try to sum up something from online resources.

1.Housework games


1) There should be a referee to decide when to start the game

2)Due to the different ages of children, different difficulty levels should be set.

Sorted by age, the difficulty of the task is from low to high:

wipe table - mopping / sweeping - washing dishes - washing clothes

The article mentions that iRewardChart is similar to a traditional chart and completed

chores are rewarded with stars that can be subsequently redeemed for another reward. (1)

I think the punishment mechanism is more like forcing children to do housework, which could not help promoting family relations. It is a conflict with our project, so we do not want to build such a punishment system.

2.parent-child relationship

1)All the family members could be players and administrators. All players have the same rights, which is not only conducive to fair play but also enhances the relationship between parents and children.

Our project is more collaborative, so all players have equal status, and the referee only plays the role of starting suspending the game. Of course, if the final reward distribution involves physical things such as candy, it needs to be distributed by the parents.


In addition, the participators of the game could be a group of friends, the relatively equal game identity is also important in this dimension.

2)three principles: Competence, autonomy and relatedness.(1)

Explore how hybrid manipulable/constructive or constructive pedagogical designs can foster positive and fun ways of doing chores.(1) Therefore, the competition between individuals is reduced, and the exploration of the game is stronger. I think the game can be divided into three difficulty levels:

Level 1: low speed & continuous ball

Level 2: medium speed & discontinuous ball

Level 3: high speed & a newly added ball

This is just a preliminary idea, and how the final mechanism will determine the increase or decrease of game content according to the difficulty of programming, but the exploratory framework of increasing difficulty is the basis.

During this week, we pushed forward the progress of the project as planned. On Tuesday, we re-confirmed the division of labor after the team composition changed, selected the option 4 plan and got the consent.

Work have done

1.Questionnaire for housework and game preference

This mission was accomplished by our teammate Zhuoran. The other teammates check it and give some suggestions for modification. In my opinion, too many of these options will increase the cognitive burden of the respondents, so I suggest Zhuoran remove some options.

In addition, the questions in the questionnaire are mostly multiple-choice questions, which can be completed quickly after testing. It is still being tested, and we will make changes based on the feedback from the surveyed subjects.

Here is the link of the questionnaire:

2.Background research

The main part I was responsible for is background research.This task will last for a while because I haven't learned about housework games that use projectors.

I plan to conduct research on three aspects:

  1. housework games
  2. parent-child relationship
  3. pong game

I will extract inspiration from them and apply them to our projects.

This background research is mainly about the first aspect and a part of the second aspect.

  1. The first paper I studied was an indoor football simulation system based on VR technology. It solves the problem of limited indoor sports space. It uses the method of suspending athletes to solve the problem of athletes achieving limb movements in a small range. Combined with the VR eye mask and the stereo imaging of the flexion screen, the athletes can perform limb movements in situ and feel the three-dimensional running and kicking.(1)


(1) Use silicone posts instead of real football, and realize 360 ° surround, users can shoot from any angle, and cause a real touch. The game experience will be better if we can add a real touch to the shot, but the specific form remains to be studied.(1)

(2) A semi-perspective VR eye mask is used. One of the eyes sees the virtual imaged football of the VR eye mask itself, and the other eye sees the information about the transition of the field and its own motion displayed on the screen. This technique will help us if we use VR eye masks and also observe the surroundings, but how to design the hardware is a problem.

Disadvantages: Although it can achieve the sensory effect of providing unlimited venues for athletes in limited space because people need activities when doing housework, the hanging method is not suitable for our solution.(1)

  1. The second thesis I studied was about how gamified domestic chores affect family interactions in a positive and negative way.


(1)The article mentioned the following reward methods:

1) Treat chores as everyone's responsibility and therefore work for free

2) Pay every trifle of the child,

3) Weekly or monthly payment of an allowance for children to complete the agreed chores (If the child fails to complete the agreed trivia, it will be deducted from the allowance.

Our reward system can be set to give rewards for completing housework every time, or issue rewards after accumulating multiple housework, motivating children to complete tasks.(2)

(2) The article mentioned 6 six elements of games:(2)

1) There is a set of rules,

2) A variable and quantifiable outcome,

3) Different outcomes are assigned different values (e.g. positive and negative),

4) Interactive: The players can influence the outcome by doing some effort,

5) The players are emotionally attached to the outcome,

6) Negotiable consequences: The game can be played with or without real-life consequences.(2)

Based on the reward system above, we need a variable and quantifiable outcome.

Different chores should have different rewards because of different physical output.

1) mop : 15points

2) sweep: 15 points

3) wipe: 10 points

  2. Determined what to improve
  3. After the group was downsized, there was a careful division of labor for each person
  4. Collected and organized everyone's comments on the presentation
  5. Start making a paper prototype

Reflection of completed tasks:

  1. Speed up communication efficiency, and respond to Facebook in time
  2. Google drive shared, put all shared files in one place
  3. Google drive upload pictures need to be named and sorted for teammates to use
  4. Help other teammates while completing tasks
  5. Communicate task progress in a timely manner
  6. When getting stuck, ask teammates for inspiration instead of thinking alone

Next step

  3. Determine the sound effect during a collision
  4. Determine the evaluation method
  5. Complete paper prototype
  6. First paper test with a paper prototype

Individual process:

Next step:

  1. collect the material and start making the prototype
  2. prepare Arduino and the collider

  4. research family games to find ways to increase interaction and improve every way of chores

Reflection of completed tasks:

  1. Drawing speed is too slow, don't pay too much attention to beauty, the main purpose is to express meaning.
  2. Pr is unskilled and cannot help teammates edit special effects to speed up efficiency.
  3. The connection between Arduino and the projector has not been figured out, and we have to find a way to solve the related code problems.

We have the first online presentation on Tuesday and Wednesday. I got some inspirations from them and commented on them. We received some feedback from classmates on the presentation.

Reflection of the comments on our team

About the feedback, I made some conclusions. Firstly, I think we need to add each type of chore expertise. What we want now is that when washing clothes, the ball is sprayed from the basin by pressure from squeezing water. A prompt tone should be added for each collision to give sufficient time for the next person to receive the ball.

In addition, we need to add a reward system to stimulate people's interest in long-term play. I think it is possible to set a rank medal for each person.

For example: Bronze-Silver-Gold/Novice-Apprentice-Journeyman-Master

For safety reasons, I think we need to drop to use the kitchen knife to catch the ball. The three suitable general categories are: washing clothes, cleaning the table, mopping the floor.

Besides, regarding the problem of the ball passing through the wall, I think it can be reminded by sound, but the wall will definitely block the light of the projector, so we decided that it is more practical to do this housework in the spacious living room so that everyone can have face-to-face interaction.

The general comments on other ideas

Since I have commented on all the projects on slack, I will just comment on the whole here. I think the most problematic part of your thoughts is not enough interaction. This is also reflected in our thinking, that is, the interaction of each different housework does not have its own characteristics.

The idea wich interests me most is GlobalZoo. I did a similar project with Arduino last semester. Generally speaking, it is to cast small cubes to change the state of the earth. So, I hope to get some new inspirations, such as how people's carbon footprint can be more intuitively expressed through interactive devices. I think the use of water in the project is a good idea, and it can also be connected with the changes of the earth. After all, it says that "water is the source of life", but I think that we can continue to go deeper and make more interesting interactions.

In addition, I think the way the earth changes states can also be enriched, not just change color.

Individual progress

Work completed

I was responsible for the persona and the drafts(storyboard+scene) in our team. About the persona, I choose two typical people who have totally different personalities and lifestyles. One of them is a full-time housewife and another one is an office worker. The main pain point of the full-time housewife is having fun with her family members and the other's is accompanying with her friends. Based on the persona, I think we need to make these links more cooperative next.

About the drafts, I drew a general effect and more than a dozen single-action diagrams. I set each action as a separate artboard so that the teammate who edits the video only needs to play these pictures in order when editing. Also, the teammate who shot the video and the one who responsible for the special effects also played very important roles. Although some pictures were not used because of editing, the effect presented in the final video was roughly in line with my requirements.

The topic I was distributed was enhanced mundane space. We introduced each other and made the team agreement.


We planed to discuss ideas no later than Saturday. We generate about five ideas at first. The first one is a physical mailbox that can connect to the phone. It can check the email and accept e-mails by vomiting out the real mail. It also contains facial recognition which is used for sharing between different people.

The second one is a backpack that can show reminders on the surface. It is designed for reminding people to take things in a physical way.

The third one is a diffuser. It is like dumping and can be used in the office. It can bring happiness and relaxation when they work busily. When the user receives an email, the diffuser spread the smell of essential oil. The user will realize that they have received an email by smelling the smell. Different kinds of smell represent different kinds of e-mail. It looks like a dumpling because the dumpling can be steamed to eat. People can connect it with steam by this aspect.

The fourth one is an altered reality headset with a knife. It is like the improved version of the game I mentioned in the last journal (Zatoichi). It can sense the chop sense and sense the state of the monster by the feeling of cut.

The last one is an indoor pong game. It aims to provide happiness for people when they do boring housework, let people feel the warmth of family and encourage them to share the housework. The general form of the game is conveying ball. The ball is virtual and can be passed between two people by sending the signal produced by the movement of "rackets". The "rackets" could be a vacuum, the mop, the broom and anything else which could be the tool in housework.

We determine to choose between the dumpling steamer and the indoor pong game. The backpack reminder is really hard to add meaningful interaction, so we dropped it.

About the dumpling steamer, we get some ideas from Lorna that it can be optimized by adding different kinds of smell depends on different people. But I think multiple smells could not be quite useful for people like me who don't have a good sense of smell. In addition, constrained by the steamer itself, its interaction methods are relatively limited.

For me, I think the indoor pong game is really interesting and has enough interaction. However, it can be a little bit difficult to achieve. I think the difficulty is not in the installation, but in the programming. How to resolve conflicts between different actions is a point that is worth discussing.


The principle of the motivation of the ball.


The general model of the whole game.


Reflection of individual work:

I generate the idea that when people chopped vegetables/meat,

A three-dimensional projection will appear. This is a game that turns boring chopped vegetables into games and aims to change people's impatience with chopped vegetables. This inspiration comes from the secure knife in the enhanced mundane space. In detail, when people cut something that cut easily, it will generate a little monster. Every time you cut it; its blood strip will drop a section. When people cut vegetables in a limited time, the monster will be killed. When people cut something that cut hardly, it will generate a boss.

However, due to the fact that people need to focus when cut things and this interaction could not change the boredom of cooking itself. Therefore, this idea was dropped.

Apart from generating the idea, I have investigated how to link every part of the indoor pong game fluently. In addition, I keep thinking about how to make the dumpling steamer more interactive in case the indoor pong game cannot be achieved.

Guest Speaker

On Wednesday’s interview with Bash Isai, we get some useful suggestion about the employment. I'm very touched by his words because I did an internship in a large domestic company during the summer vacation, and I did find the difference between a large company and a small company. In my opinion, the division of labor systems of large companies is more rigorous, but it also leads to very low processing efficiency of some projects. In this regard, I think that small companies do better, but at the same time, it is difficult for small companies to reach some large projects. specification. As an interaction designer, I found that communication with colleagues in various departments is very important. If this is not done well, it may lead to a lot of duplicate work.

On the 15-word part, I write “I’m unique because I’m a designer”. Compared to others, I wrote more general, but I think this is the confidence a designer should have. Afterward, I know I should think of something specific. This session really deepened our clear understanding of our advantages. “I need to find what makes me unique” is a useful sentence.” Don’t be afraid of failure” give me the motivation for carrying out our selected project. I think we can figure it out even we even if we still have some technical doubts.


On Tuesday, we learned a lot of new ideas and came up with a new idea based on all the posters on the table. Here are the ideas and inspirations we get on different tables.

Guided movement

Fitness blankets that guide people to do the right moves. This blanket is made up of many small squares. When people do dangerous moves, they will stretch out the small squares to support them. This auxiliary behavior gave me some inspiration, maybe I can use this mechanism for other operations. At the time, I thought, maybe we can make the barrier-free ramps portable so that in any case, people don't have to worry about the obstacles of the steps.


Sassy tech

The door shaking hands impressed me. But I think its interaction is not enough. Maybe it can also set some error penalties to play the anti-theft function, such as getting a hot or slight electric shock when the wrong fingerprint is detected after entering the wrong password.


Altered Landscapes

The one we discuss the most is a poster is Zatoichi, a blindfolded game. We think the idea is interesting but the game may be boring. We suggest adding more actions and more weapons to the game. For example, the weapon can be shield, sword, knife or ax. The voice could be different because of the distance. In addition, it can set online PVP mode. The player can rotate on a rotating chassis to attack the enemy around them.

Enhanced mundane spaces

The topics I chose, at last, were guided movement, sassy tech, enhanced mundane space.

The idea of floor coloring in enhanced mundane space inspires me. Maybe we can generate some ideas about housework and make boring housework as a kind of game. I think we can use garbage as a little monster when sweeping the floor. Different garbage can be represented by different types of monsters, and different amounts of garbage can be represented by monsters of different strengths.

Idea Presentation

About the presentation on contact, I get some inspiration from classmates. Some of the ideas have aroused my interest,especially some musical ideas.


The idea of "representing the melody of music with the shape of a string" is great. This means that music has infinite possibilities. The operations "play/create/explore" is practical enough to implement it. The most thing I am curious about is showing the natural scene by the music. This idea is a good direction to develop and I also curious about the practical implementation method. In addition, crappy operations can be added to increase the difficulty of the game for advanced players.

Percussion Glove

The drum is a novel idea I never thought of. I thinking the author can get some inspiration from the game "Drum Master".A single rhythm may be a little bit difficult for the player to play with and may use fragmented music instead. This can slightly reduce the difficulty of matching the game and enhance appreciation.

Immersive Art Gallery

Nezha is a great Chinese animated film, and the magic scroll in it left a deep impression on me. I think that the author can set specific tasks in advance, and then set the vibration and olfactory sensor performance methods in advance according to these tasks. In this way, the implementation could be simpler. Of course, I also look forward to better ways to achieve the world in painting.


About my remote presentation, I'm not quite satisfied with it because of the bad sound effect. Actually, the pre_recorded video is quite clear. I don't know what that sounds like to the field audience, but the volume on the zoom is really low. I sent my poster and the subscript on slack after the presentation and I hope all classmates can understand my concept.

Besides, the concept conveys by the poster is not quite directly. Vectors should be replaced by detailed pictures so that the concept could be understood more easily.

In addition, the specific implementation methods still need to be optimized. For example, the operation of pouring wine is too complicated to carry out. I need to ensure that the vibration, water sound, and visual effects are completed simultaneously, I cannot figure out some effective way to implement it. Maybe it could be changed to some other implementation plan. I will talk about it with classmates and get some suggestions from them,

About soldering

Since I only entered Australia on March 3rd, I was not able to participate in this workshop and experience the soldering. I have no experience in electric welding, but I have observed the general method of using electric welding by my friends. I will ask students who have mastered this skill in the next workshop.

The table dating simulator provides an immersive simulated table dating scene to reduce the tension of offline dating.


The inspiration is derived from the science fiction adventure film "Ready Player One".

The hero and heroine fall in love through virtual game characters. The Interaction is inspired by this clip in the film. In this video, the actor uses a VR-like glasses and gestures to date a girl in a virtual game. So I also want to achieve the effect of dating in a similar way.

In my vision, users can experience the activities in the scene immersively and the feedback of the virtual characters through vision, hearing, touch, and smell.

For example, when a user pours wine, they will hear running water, smell the wine, and feel that the weight of the bottle becomes lighter. Different pouring speeds present corresponding pictures.

If the task is done perfectly, then the virtual character will appreciate it. Such kind of communication can reduce the tension of people when dating. Users can also experience different operations, such as lighting candles, cutting cakes, and barbecue.



Establish a real table scene to provide users with multiple tasks

scenarios on the table to interact with.

About me

My name is Yifan Wu and my major is Interaction design. This is my second year in postgraduate. After a year of study, I have a general understanding of this major. My level of design has improved, but there is still a lack of programming. I hope that this aspect can be strengthened in the next study. In addition, I hope to try some different ways of interaction and gain something different in this course.

About expectation

I think we are going to learn how to build physical computing environments in this subject. I want to learn how to implement deep interaction in code. The thing I fear about is also coding, especially using code to implement complicated physical interaction. In addition, I heard that we need to go to the machine room for operation, which is a new experience for me. At the same time, the study of safety knowledge before class improved my safety awareness and I look forward to the experience of the studio.

I'm looking forward to going back to school and see guys as soon as possible.
