This week I posted a video on miro. In this video, I introduced the background of our group's entire project, target users, recap and my personal work progress. After watching the videos of other students, I think there is still a lot of room for improvement in my video. This refers to the possibility of improving video production and presentation methods. I hope I can make progress when I make the video next time.

Here are the shortcomings in my video that I summarized:

1. No subtitles are used in the video. When there is little text content in the video, the audience should concentrate very much on listening to the content in the video, which requires high pronunciation. If there are unclear words and the pronunciation is not standard, the audience may not understand the video. Content. As a person whose native language is not English, my pronunciation is not standard, so next time I make a video, I will try to add some subtitles to help the audience understand.
2. The picture layout in the video is not attractive. Many pictures in the video only show the title, there is no key point, and there is no picture. Pictures can help viewers understand my project and make the slide content more attractive.
3. In the process of displaying the content of the video, I did not show the order of the content of the speech, such as making a catalog, dividing the content of the speech into several parts, so that the audience can have a clearer idea when listening, they can easily find To their most concerned part. However, my video does not divide the content of my talk into a subtitle, and the audience may be confused when they hear it.

Reflection

On Friday, I saw the feedback everyone gave me on Miro. I have listed suggestions related to my prototype and concept. I responded one by one.

1. "You may consider some sound effects either, for example, when users put the sound piece into the trash can, you can add a sound effect of throwing rubbish into a trash can."

The students suggested that we use some music as a reminder. This is a good suggestion, but I will consider whether it is necessary. Because our product is a product that plays music, I plan to use lights, smoke and other visual effects to show the user whether each step of the operation is successful. But there are some steps that can't be expressed with light, for example, deleting sound. Because the deletion of the sound is invisible, when the user deletes the sound successfully, he needs to get a "successful" signal feedback. I may add a sound signal at this step.

1. "Do you have a plan on hiding the wires? We would suggest trying to use wires that are bundled up together to make it cleaner and then wrapping in some some heat shrink perhaps to clean it up."

At present, because we have not yet determined whether to use this set of plastic chemical experiment tools as the final exhibit, and some sensors have not been installed on the beaker. Whenever a sensor is added, 2-4 wires must be added. Our team has also been looking for ways to hide wires. Our current plan is to tie all the wires together to make them look less messy.

1. "you can consider includes defining how each interaction triggers emotional responses in users and link the responses back to your problem space and team domain."

This is a good research direction, I will do some research in the next paragraph. The ultimate goal of our product is to help users create their own mixes and let users design their own exclusive sounds. We will do some user tests and interviews after the product prototype are completed. I believe we will get a lot of valuable feedback .

4 “we would also suggest having a way of confirmation of deleting audio when near the trash can incase a user is holding a test tube and gets distracted by something else and walks near the trash can by accident.”

This problem will be emphatically studied in the next stage of prototyping. At present, the choice of ultrasonic distance sensor will indeed cause misoperation during use. For example, the user does not want to delete the sound, but just accidentally moves the beaker close to the trash can, and then all the sound is deleted. If I can add a "confirm" step during the user's deletion of the sound, it may solve the problem. Just like when we use the delete function on the computer software, a window will appear on the screen to let us confirm whether we want to delete.
