Plan A

Adding the microphone and LED light on the base of my current prototype. The LED will light up if the microphone is sensing the input correctly - This is a similar approach comparing to the first prototype I have created, the difference is I will place the microphone in an obvious place, without adjusting the position, the microphone can easily detect the voice input

Testing Procedure

In the beginning, I recruited 2 participants to test this plan. They were required to practice the breathing instruction with the aid of microphone and led.

Step 1: Breathe in for 4 seconds, if the users breathe in, the light will be on, if the microphone sense any input, the light will be off.

Step 2: Hold breath for 7 seconds, if no input is detected, the green light will be on, the red light will be off if the microphone do not sense any input.

Step 3: Breathe out for 8 seconds, if the users breathe out, the light will be on, if the microphone do not sense any input, the light will be off.

The breathing instruction will be activated when the user's heart rate exceed 98(It should be 110, but for easy testing, the standard lowered to 98)

Result

The result indicated that the user 1's heart rate does not fall under 98 until the 8th breathing instruction practice, it is an unacceptable number because when user are suffering from panic attack, this method can't calm their emotion immediately.

The result indicated that the user 1's heart rate does not fall under 98 but keep raising when he is practicing the breathing instruction, it showed an opposite result of which I am looking for.

Feedback

The users reported that focusing on the microphone and LED light makes them nervous especially when the LED light switch on and off during one simple action. They are confused of what they are doing. Also, they preferred not interacting with the microphone which allowed them to do the breathing exercise in their own pace and body position.

Plan B

Adding a buzzer to the system to indicate the stage of breathing instruction. In stage one, it generated the beep sound once. In stage two, it generated the beep sound twice...

Testing Procedure

In the beginning, I recruited 2 participants to test this plan. They were required to practice the breathing instruction with the aid of a buzzer.

Step 1: Breathe in for 4 seconds will happen after the first beep sound.

Step 2: Hold breath for 7 seconds will happen after the second beep sound.

Step 3: Breathe out for 8 seconds will happen after the third beep sound,

The breathing instruction will be activated when the user's heart rate exceed 98(It should be 110, but for easy testing, the standard lowered to 98)

Result

Both participants failed to lower their heart rate when the buzzer is applied to the prototype.

Feedback

The participants said the buzzer was very annoying, the beep sound made them more nervous and anxious. Longer the sound duration, higher the anxiety. They thought it was not a good improvement if I add this to the original prototype.

Short Conclusion

I am not going to modify any setting in this part. But I will redesign the container to hold the major components and redesign the UI elements for better user experience.

Short Conclusion

I am not going to modify any setting in this part. But I will redesign the container to hold the major components and redesign the UI elements for better user experience.

Redesign

The original design is a white box. It was simple and clean. Suggested by other team members, they believed adding more colour and adorable features to the box can calm the users easily when they are interacting with the device.

Design A

The first one is adding patterns like this on the white box. It does make the device look colourful. But I wonder whether it would be too colourful that may distract users from conducting the breathing practice.

Design B

The second design is painting different colours on the box. But this one seems to be meaningless and lack of design elements. There is not necessary to put six different colours on it. Although the colours make it look better, this pattern brings no impact to the product itself.

Design C

I found a very inspiring pattern on the internet. In a white cube box, there are only two sides painted with colours. This is a very good design pattern that are well fit to my prototype. One colour side indicated that all essential features are on this side, another colour side are printed with breathing instructions. When the user forget the rules, they can quickly turn to the other coloured side and look deeper into the instruction. But considering the text and background colour, I will try different combinations to find the patterns with the best visual effect (Clear words and calming background colour)

Video appraisal

After reading the feedback, I have summed up three major ideas that can help me improve the current prototype. One is related to the product physical appearance; Two are related to the functionality of the product.

1, Design

The original prototype is a white box containing the Arduino kit and accessories. All the components are placed inside the white box. The user can see the OLED screen easily but look deeper to see the LED light since there is a small gap inside the box. The other groups suggested me to put the LED light on top. of the box. So that the users can see the LED light instruction easily. Moreover, I can also write words on the white box to indicate the meaning each LED light since they were very confused with the set up of LED light in the video demonstration. Also, they suggested me to put all the components in a smaller box. Since the white box I show in the video demonstration is too big which is not portable.

2, OLED screen UI

The users indicate that the Breathing instruction shown on the OLED screen is not clear and make them confused. They suggest me to write a general instruction of the breathing practice process before it starts. For example "Since your heart rate is above... Please follow the following instruction to regulate your heart rate. Step 1: Breathing in for 4 seconds ...". Also I can add the detail instruction on the white box, for example, use your nose to breath in and your mouth to breathe out.

3, User Interaction

Most of the other groups indicate that there is a lack of physical interaction in this prototype, but just a OLED screen demonstration to guide users to finish a breathing practice. They suggest me to put a microphone there to record whether the users are correctly performing the breathing instruction.

I will finish improving the design and OLED screen UI before Week 13. Also two user interaction testing plan will be carried out within the following three weeks.

Plan A,

Adding the microphone and LED light on the base of my current prototype. The LED will light up if the microphone is sensing the input correctly - This is a similar approach comparing to the first prototype I have created, the difference is I will place the microphone in an obvious place, without adjusting the position, the microphone can easily detect the voice input

Plan B,

Adding a buzzer to the system to indicate the stage of breathing instruction. In stage one, it generated the beep sound once. In stage two, it generated the beep sound twice...

Video Demonstration

This is the prototype video I created for this project. The first part introduced our team domain and problem space. Followed by the target audience and the intended experience that i wish to bring to them. The second part is a 1 minute user testing, the interaction plan and real demonstration will be recorded in this part. The third part is the major components of this project which was simply mentioned in my week 8 journal, some changes are applied in the final prototype. The fourth part is the functionality description, including heart rate visualisation, breathing instruction instruction and heart rate detection and judgement. At the end of the video, I will explained the simulated features and what I am looking for and planning to implement in my final product.

Code

void loop() {

  uint8_t rateValue;

  uint8_t goodRate = 0;

  int soundsens = analogRead(soundpin);

  heartrate.getValue(heartratePin); ///< A1 foot sampled values

  rateValue = heartrate.getRate(); ///< Get heart rate value 

  if(rateValue)  {

    Serial.println(rateValue);

    goodRate = rateValue;

    u8g.setFont(u8g_font_unifont);

    u8g.firstPage();

    do {

       if(goodRate!=0) {

        char beat[8];

        sprintf(beat,"Beat:%3d",goodRate);

        u8g.drawStr(20,40,beat);

       if(goodRate > 98){

            

            u8g.firstPage();

            do {

            adraw4();

            digitalWrite(ledPin, HIGH);

            digitalWrite(ledPin2, LOW);

            digitalWrite(ledPin3, LOW);

            } while( u8g.nextPage() );

            delay(4000);

            u8g.firstPage();

            do {

            bdraw7();

            digitalWrite(ledPin, LOW);

            digitalWrite(ledPin2, HIGH);

            digitalWrite(ledPin3, LOW);

            } while( u8g.nextPage() );

            delay(7000);

            u8g.firstPage();

            do {

            cdraw8();

            digitalWrite(ledPin, LOW);

            digitalWrite(ledPin2, LOW);

            digitalWrite(ledPin3, HIGH);

            } while( u8g.nextPage() );

            delay(8000);

            u8g.firstPage();

            do {

            ended();

            digitalWrite(ledPin, LOW);

            digitalWrite(ledPin2, LOW);

            digitalWrite(ledPin3, LOW);

            } while( u8g.nextPage() );

            delay(4000);

            break;

        }else{

          continue;

          }}

      else {

        u8g.drawStr(10,20,"Wait!");

       }

      } while ( u8g.nextPage() );

  }

  delay(20);

}

There are two major components in this program. The first part is displaying heart rate on the OLED screen by changing the unit of the default heart rate sensor data to suit the Arduino working environment.The second part is identifying whether the user's heart is above 98, the 4-7-8 exercise will be activated in this case with the aid of LED light. After completing the 4-7-8 exercise, the system will check the user's heart rate once again to determine which situation they are experiencing.

Reflection

Before finalising this version, I have got a very big problem when I was doing the user testing with my previous prototype. In the previous prototype, I installed a microphone to guide users to practice 4-7-8 exercise, the green light will be switched on when the microphone sensed the correct input throughout the whole 4-7-8 process. They need to perform the correct action to jump into the next stage, for example: Breathe in for 4 seconds -> Hold breathe for 7 seconds. But no user reported a drop in heart rate even 10 rounds of 4-7-8 exercises were performed. But this situation got better when I removed the microphone. It may be due to the stress and anxiety brought to the users when they were doing the task wrongly. For my final prototype, I removed the microphone and replaced it with the 3 colors LED lights.

Arduino Setup

The whole adruino setup includes the main board, Gravity heart rate sensor, 1.3 OLED Display and three led lights in red, yellow and green.

Heart rate sensor

When the heart rate sensor is attached to the human body where shows strong pulse, the red light on the sensor will start flashing. It will generate heart rate data after 5-10 seconds depending on the connection stability. But it may stop generating data if the sensor disconnect from the body part. Also. this heart rate sensor provides two modes for data generation, including digital and analog mode. In this project, only the digital mode will be used.

OLED screen

The original function of this screen is to display the user's heart rate. Also, this screen will display the instruction of 4-7-8 breathing technique when the user's heart rate exceeds 98, the 4-7-8 breathing technique training program will be activated. In the first 5 seconds, the screen will display 'The program will be started in 5 seconds'. After the 5 seconds count down, the following instruction will be displayed.

1, Breathe in for 4 seconds

2, Hold Breath for 7 seconds

3, Breathe out for 8 seconds

4, You have completed this program, please wait for the system to detect your heart rate

If the user's heart rate is 98 or above, the 4-7-8 breathing technique training program will be activated again. If the user's heart rate is below 98, the user's heart rate will be displayed on the OLED screen.

LED Light

These LED light is designed to help user better follow the 4-7-8 exercise. When the OLED screen shows "Breathe in for 4 seconds", the red LED light will be switched on. When the OLED screen shows "Hold Breath for 7 seconds", the yellow LED light will be switched on. When the OLED screen shows "Breathe out for 8 seconds", the green LED light will be switched on.

Interaction Plan

1, Before user testing, the user will read the testing instruction on a computer and rest their body for a few minutes to regulate their body status.

2, After that, they will attach the heart rate sensor to the the body which reflects strong pulses.

3, The user will be told to move their body to generate higher heart rate to simulate the situation when people are anxious and stressful, they will be directed to the breathing technique instruction program when the heart rate is 98 or above.

4, After practicing the breathing exercise, the system will detect the user’s heart rate again, which takes 5-10 seconds to generate the result. Depending on the result, the user will be directed to the breathing technique instruction program if they heart rate is still 98 or above; the heart rate will be displayed on the OLED screen if the user’s heart rate is 97 or below.

Arduino Development Plan

Finally, I receive Arduino kit this week. I have divided the whole project into three parts.

Main topic

This is a bracelet and necklace combination to monitor user's heart rate and trigger the breathe technique training program when the heart rate exceed a given threshold.

Part 1

A heart rate sensor is installed in a bracelet that used to record the user's heart beat. The basic function of this bracelet is display the user's heart rate in an OLED screen. There are two mode this model, including sport mode and normal mode. The sport mode disabled the breathe technique training program even when the user's heart rate exceed a given thresold. The normal mode keep track on the user's heart rate and it will trigger the breathe technique training program when the heart rate continuously exceed the threshold in a short period. This OLED screen required user to build the application based on u8glib. The user can draw string and line on the screen, which is adjustable and changable.

Part 2

A breathe technique training program is installed in a necklace. This program will be triggered when the heart rate exceed a given threshold. It guides user to complete the 4-7-8 breathing training on the OLED display. In the first 4 second, the program requires users to breathe in. In the next 7 second, the program requires users to hold their breathe. In the last 8 seconds, the program requires users to breathe out. A count down timer will be shown on the bottom right corner in all situation.

Part 3

A microphone and LED light setting is installed on the necklace. For breathe in and holding breathe stages, the LED will light up when no sound is detected, which means users are not breathing out. For the breathe out stage, the LED will light up when sound is detected, which means the users are breathing out. This is another visual aid that help users recognise the breathing stage they are experiencing.

Part 4

This is an optional setting, an essential oil may be considered to provide a more effective effect to help bring down users' heart rate.

Recap from last week

Due to the internet problem, I still can't connect to zoom and attend online activities organised by the teaching staffs. Also, I still haven't received my Arduino kit, I am very worried about the development progress.

Work done

I have conducted an interview with a person who had suffered from panic attack. He refused me to take video of the whole interview but allowed me to take notes on her experience.

Interview short recap

xxx is a 29 years old motion graphic design working in a content delivery compony in Taipei. He has suffered from the panic attack since he was 25 years old. It brought significant negative effect to his daily life and social interaction with friends. He avoid everything that cause his intense fear, such as water and elevator(Drowning experience). He avoid all social activities related to water, such as swimming and diving. He even avoid public transport and elevator. These environment setting may seems like claustrophobia. But in fact they are panic attack, since the patient are fear of these suffering instead of actually experiencing these environment. The imagination of these cause him physical and cognitive symptoms, including the rise in heart rate, dizziness or even shortness of breathe. The panic attack usually last from 5 to 15 minutes, the worst case is xxx feels the increase in heart rate which trigger a strong fear of suffering from heart attack that make thing worse. In his opinion, there is an instant need to bring down the heart rate to prevent the worst case happen.

Product requirement

Based on the interview feedback, research article and educational videos, I have list a few compulsory features that my final product should consider.

1, This project should be portable. Since the user has an instant need to reduce the heart rate and anxiety. It should be small or light enough for user to use it anytime and anywhere they want.

2, The material can be in a shape of bracelet or necklace since it is convent for the user to practice immediately and keep track of the heart rate

3, The structure and durability should be in a good condition. As this product is wearable, people may cause physical damage to this product. It should ensure toughness to prevent from breaking.

4, It should be instructional to guide user practice the 4-7-8 breathing technique fluently.

Plan

According to the online order stays, I am going to receive my Arduino kit in week 7. I will start doing prototype for this product and listing the potential problems that I may have during the development period.

Reflection

Due to the coronavirus, our physical contact hours become online learning activities. Although it is one of the most reasonable choice to maintain teaching quality, the internet in my living area is too unstable that hindered my learning and development progress. For example, I have disconnected from zoom for multiple times, also the sound and video quality were too low to help me focus on the teaching content. At the same time, our team project has switched from our hand gesture controlling game to another product built for educational purpose. Due to the dissatisfaction and feedback from our teammates, we have once again decided to change our topic to breath controller.

To dig deeper into the breath controller project, we have review Paula's idea, using 4-7-8 breathing techniques to help people sleep better. I have researched a lot on this breathing technique, I found out that, not only the sleep quality would be improved, but also reduce tension and anxiety. One key point in all these effect was 'This breathing technique help reducing heart rate'. My whole project is developed based on this key point. Although the 4-7-8 breathing technique is used again, my project targeted on different group of users, the setting of my final product will be adjusted to fit their needs.

There are two potential problem that may affect my working progress. The first one is the delivery time of my Arduino kit, according to the online order, it took about 10 days for me to receive everything I need to build the project, including the starter kit and different sensors. The second one is the internet connection, loading Youtube video is a disaster in my living area. It took more than 3 minutes to load a short video in a very low quality. Since I am using my desktop, I can't simply move it to another place, but stay home to wait for a better connection time slot. I wish I could overcome the problem in the coming weeks.

Task for this week

1, Research on the target audience who has a need of lowering heart rate

2, Solution for integrating the breathing techniques with daily activity

3, Learn Arduino and Purchase Arduino kit online

4, Solve the slow internet connection problem

Pitch

Body as controller is our domain, we have developed a project called Handy Aero, which required users to use their hand gesture to control the game characters. Our group has selected the pre-recorded option for the presentation. My part is user study. The main target audience our group focusing on are "People who have mysophobia" and "People who are tired of using physical controllers".

User Research

Because of the spreading coronavirus, users are afraid of sharing and touching objects in public area. In Hong Kong, most board-game cafe and internet cafe are even closed to stop the spreading. To enjoy gaming in this special time, gesture controller is a wise choice. Without touching any physical objects, users can enjoy gaming with others. But the limitation is, we can't adopt this controlling method on complicated games. In our project, we planed to build an aircraft fighting mini game to maximise the adaptability of gesture control devices. Also, suggested by the gamers, traditional gesture controllers are lack of feedback and interaction, we planned to build a wristband that generate vibration and other interactive elements to improve user experience in gesture control.

Feedback

We had received a lot of feedback saying that our project was too similar to leap motion and Kinect. What we wanted to was building something on top of it, but not building something similar to it. In this project, we planned to buy leap motion for gesture recognition, and created two wristbands that provided feedback and hopefully generated resistance to simulate the aircraft flying environment. But it was not discussed during our pitch due to the uncertainty and the lack of planning. After discussing with tutors, our group planned to focus on another topic in the same domain that allowed us to create something more interactive and meaningful, for example, mental and physical health, vehicles (toy) racing. Our next group meeting will be held on Friday this week. I hope we can come up with an extraordinary idea to replace the existing one.

World Cafe

I have participated in many group discussion on that day, the most memorable topics were emotional intelligence and body as controller.

Emotional intelligence

Our group has came up with a new design named traffic manner. When you are driving a vehicle, some people may give way to you and you want to say "thank you!". But it would be dangerous to do that on road. Traffic manner provides a solution to deal with this problem. By simply pressing one button, a smiley face with the word "Thanks" will pop up on the top of the car:)

Body as controller

This is the topic that I like the most, the idea running hand inspire me to turn my hand into controllers that control different mini games. It will be further discussed in my next documentation.

Inspiration

Basically, this is an interactive game that design for users to use their hands as controllers to defeat enemies by flying an aircraft. There are different flying modes that changed by users' gesture. There are two controllers (Left hand and Right hand).

For the left hand, different gestures represent different ways of attack. For example, pointing out the thumb and index finger generates a normal attack; pointing out the thumb, index and middle finger generates a power attack.

For the right hand, different gestures represent different ways of attack. For example, pointing out the thumb and little finger generate a slow speed but very accurate flying mode; pointing out all fingers generate a fast very inaccurate flying mode.

This game is inspired by a poster called running hand, by using hand as a controller, the gamer can control the character to pass different levels. It made me think of a mini game I played in my childhood, which was using hand to simulate aircraft to fight the bad guys. This is a very good opportunity for me to make this childhood dream comes true. Also, I search for a lot of similar games to come up with this project.

Target User

This idea is designed for the public, anyone who are interested in gaming can try this game. There is a special case that I want to mention here. Mysophobia refers to a pathological fear of contamination and germs. They have strong fear toward germs and virus, using a gesture controller can prevent them from touching the physical controller while gaming with other people. This project provides them a brand new option for gaming.

Idea Presentation

In week 2, both Tuesday and Wednesday were presentation sessions. Most of the students presented in class, some of them were presenting through zoom due to the coronavirus. It was a very enjoyable session, I was inspired by many ideas. The most remarkable one was the Floor coloring project. This device will project paintings on the floor, the user can adjust the color of the paint through the bracelet, they will start mopping the floor when the color is selected. In reality, a tool or device like this can be invented for house decoration. To make this idea more interactive, they can install a perfume box on the device as well. For example, when yellow is selected, the user can mop the floor with a lemon smell. Other than this project, there are lots of smart device idea that inspired me, for example, smart kitchen, smart wardrobe, smart knife, even for the smart floor. All the idea combines together can form an IoT smart home system.

Idea Grouping

Grouping themes

At the end of the presentation session, students grouped similar ideas together and wrote them on a piece of paper. I group the ideas involved in plants together. It seemed that these ideas could form a bigger idea that involved human value and more interactive. Also, I made a stress release group, there were three projects ideas that created to deal with stress problem, including smashing it, stress relief ball... I really look forward to the world cafe next week. According to the timetable, there will be an Ideation and discussion around themes revealed through inspiration presentations. I wish I can group up with the students who want to work on a similar project as mine.

The perfume maker

This is an interactive game that allows user to feel other's emotion and share their own by completing three tasks.

Step 1:

In the beginning of this game, the user will wear the AR glasses that shows the message left by the previous user, it could be some good memories or some kind of frustration. At the same time, they will smell the perfume that he has created for the message. For example, someone created a (peach+apple+rose) perfume to commemorate her first love.

Step 2:

Next, the user will solve the perfume code on the AR glasses by identifying what ingredients the previous user have applied on the perfume making. New ingredients will be unlocked depending on the number of time the user spent on the task.

Step 3:

After that, the user will randomly select one scenario on the AR glasses, which may be related to love, friendship, family, workplace... They can record their feeling toward this scenario or leave anything they want as a message. After doing that, they can make their own perfume by following some guides on the AR glasses.

Today we have discussed the fear and expectation of this course

Fear

1, I have never taken any 4 unit course until this semester. I am not able to predict the workload and the amount of time I need to spend on this course

2, Some students said this course required a finished product at the end of the semester, I am not confident with my building skill.

3, Team coordination/ Time organisation are always the big problems in a group assignment.

Expectation

1, Learning the new technology, such as the laser cutter, 3D printing machine... and applying them on this project through the innovation lab tutorial.

2, Coming up extraordinary ideas with my team members

3, Using different tools and equipments to cope with the difficulties I faced during the prototype making, learn from the mistakes and safely use all the tools.

The HCI grand challenge topic is learning and creativity

Summary

The way how people learn has changed rapidly. The use of technology in the contexts of education and creativity is very common nowadays.The new generation of learners prefers a different learning style comparing to the past learners, but these learning style has a lot of challenges to deal with. For example, mobile learning is a big trend, students can acquire knowledge anywhere anytime they want, but the effectiveness is something educators and researchers need to consider.

The Serious games for learning was the main topic that I focused on. I believed that keeping a balance between seriousness and gaming was the biggest challenge in creative learning. When we are making the course content more attraction, gamification elements are used frequently, for example, bringing excitement ad fun to the learning journey. But too much fun would distract students from learning. I suggested that educator should use the technology to add gamification elements to the game instead of merging the gaming content with the course content. For example, they can use an AR glasses to guide student to finish a specific task.

Ideation

♠ = Design to / for

♣ = Place

♥ = Interaction Mode

♦ = Interaction Quality

In our group, we have selected an idea which is "Using smell to guide cleaner to clean up a specific part of the hospital." For example, cleaner A is responsible for the apple smell, any location smell like apple will be included in his cleaning task. It is a very interesting ideation method, our group has come up with a lot of interesting ideas and it help brainstorm the project topic.

About me

Hey guys! My name is Cheung Ka Ho, just call me John:). This is my last semester in the Master of interaction design. My hobbies are doing animations and thinking new ideas to make the world a better place. I hope this course can help me build something great to inspire other people.

Expectations

Before attending the contact session, I believed that this was one of the most challenging course in the curriculum. I worried about the work load and lack of skill and ability to make concepts alive. The projects in previous years brought me huge pressure because the fancy features and technology were not achievable by myself. In the coming weeks, I wish I could acquire different skills and knowledge to cope with the new challenges, such as using laser cutting and 3d printing techniques to build a real physical object.
