Reflection for the 4-week workshop

      • Describe your partner

        • My partner is a cool boy who loves to play computer games and watches movies on the computer at home.
        • He loves to play the small games that don’t require too complicated movement, as he has the constraint on the left side of the body.
      • What are their desires/challenges/difficulties?

        • He encounters the difficulties that when he plays computer games, he can’t play the game requiring both hands because his left hand could not move well. 
      • What is your project? (Description + Photos and/or Videos)

        • We’d like to propose a controller that could control by his right foot so that by substituting the left hand to the left foot, he can play games that require two hands
        • final versionfinal version pic2
        • That’s our final version of the project. It has four pedals fixed on the board and each of the pedals is programmed with the key “W”/”A”/”S”/”D”. 4 wires of USB come to the USB hub and the USB hub connects to the computer.
          • The reason why we programmed W/A/S/D into the pedal is that many games require the WASD for the movement of the game figure, and our partner did not be able to play those games. So we want to use this board to help our partner to play the game well and try more different kinds of games.
        • Once the user uses the foot to click the pedal, the signal of that specific key is activated and it instantly reacts to the computer.
        • Development process. Include photos and video(s)

          • I came up with the idea of the foot controller, and we searched online for the hardware part of our project. Finally we found that Taobao has a store that provides the pedal which can be customized the key. We chose a size that is suitable for our partner’s foot. We also bought a USB hub for sorting the wires better.
          • After the pedals and USB hub arrived, we programmed it with the given tutorial by the seller.
          • We first assemble 4 padels in this way
            • However, we found that in this position, the user could easily be tired as the user has to move the foot position quite often.
          • Then we change the padels in this position
              • We found that in this position, the user only has to change the foot’s direction from left to right when the user needs to click S+D. Apart from that, every click and combination could be click in the left food direction.
      • What were your difficulties?

        • Before the user testing with our partner, we thought that the biggest difficulty we face was how we should put 4 pedals in a way that is more convenient and efficient for the partner to use.
        • However, during the user test, we found that the biggest difficulty is that he actually did not like the idea of playing games with the left foot and it’s hard for us to know the reason. When we opened several games for him to test the pedals. Even with our instructions and demonstration by ourselves, he did not like to use the pedal for games, and the most difficult thing for us is that since he’s deaf and his handwriting basically can’t convey his meaning(he could only write around 2 characters at a time) We can’t get the reason why he thought the pedal is not useful for him. And his mother, who does not like him to play the games, was kind of unwilling for him to try more about these pedals. Since that’s the one and last time we tested for this pedal, we don’t have more time to test it. 
        • We asked our partner whether he wanted to keep it or not, and after several confirmations between his mother(who was not really willing to do so…) and him, they brought it home and said they might test it more.
      • What did you learn from this 4-week workshop?

        • Looking back at this 4-week workshop, I learned that communicating is the most important part of designing a thing for others. Since our partner is deaf and lack of the ability to write a full sentence. It was hard to get his thought and understand what he actually wants. I remembered the first time we met with our partner and his mother. Most of the time, the conversation was dominated by his mother, and my partner could not have a chance to speak for himself. We actually did not get much information about himself. After the first time, we tried to ask our partner without the presence of his mother, but it turned out that he could not understand our writing and it was hard for him to understand a full sentence. When he could not understand our meaning, he was anxious and really wanted to find his mom to speak for himself. 
        • If we could have more time, I think we might be able to find a really effective way to communicate with him. However, within such a short time, we found that it is hard to change his tendency to find his mother to speak for him and let his mother translate the meaning. 
        • Although our project eventually did not perform well and improve much of his life quality, it is a precious chance for us to know that through the process of designing, finding an effective way to communicate and knowing what the user wants is the foundation of design. Without these, all the designs we proposed may not work for our real users.
        • We would keep in touch with our partner to see if he has more feedbacks for our project. All of us have learned a lot and I believe we will learn from this lesson and improve more in the future design projects.

  1. Reflection on the field trip
    1. A campus behind Meng Cafe & Vocational school
      1. Describe your observations on their classes
        1. The most memorable thing for me is that the autism kids were really diversified in terms of their behavior towards other people. Some kids were really happy and excited when seeing other people(especially we visitors), but some kids are quiet.
        2. Some autism kids are always immersed in their own mood and own feeling, it’s hard for them to stay focus sometimes.
      2. What technologies can improve their learning?
        1. Maybe some technologies to help them to stay focus more? For example, a watch displays the specific task they should do. Like when they need to do the paper cutting, the teacher send a signal to their watch, and the watch will constantly remind the kids that their task right now is paper cutting and kids should stay focus on it.
      3. Overall experience and observation
        1. Maybe just coincidence, but my first impression is that students on this campus are more mature than students in the previous campus.
        2. The design of the 1-to-1 class where the teacher taught the class surrounding the same topic in a consistent and interesting way was impressive.

  • Project development (individual)
    • Describe your partner
      • My partner is a cool boy who loves to play computer games and watches movies on the computer at home. 
    • What are their desires/challenges/difficulties?
      • He encounters the difficulties that when he plays computer games, he can’t play the game requiring both hands because his left hand could not move well. 
    • What is your project? Redefine if needed
      • Because the idea came up just recent days (As we moved the idea from the writing board to this, since that board is not the real need for him. We’d like to change to a new idea that could be realized within a short period of times). We right now only have a rough idea:
      • We’d like to propose a controller that could control by his right foot so that by substituting the left hand to the left foot, he can play games that require two hands. 
      • We bought 4 pedal keyboards and one USB hub from Taobao. By using the software Taobao provides, we set the 4 keys to “S”/”W”/”A”/”D”. 4 pedals are connected to the USB hub and the USB hub should connect to my partner’s computer. Then we stick them on a paperboard, which makes 4 pedals more stable.
    • Development process. Include photos and video(s)
      • Since he was not in the class last week, we can’t tell whether his left foot could also move or not. So we assume that his left foot cannot move as he is having cerebral palsy on the left side of his body. 
      • We first assemble 4 padels in this way
        • However, we found that in this position, the user could easily be tired as the user has to move the foot position quite oftenly.
      • Then we change the padel in this position
          • We found that in this position, the user only has to change the foot’s direction from left to right when the user needs to click S+D. Apart from that, every click and combination could be click in the left food direction.
        • Next Step
          • Meet him, test it with him
          • Install the keyboard in his house under his permission.

  • Reflection of the field trip (individual)
    • The field trip on Wednesday is really educating. As soon as I entered the school, I suddenly realized that although the special school is also on Century Avenue, where our school is located, if we don’t pay attention, we wouldn’t find that there are many people in the world who are suffering from the disabilities. This group of people deserves more care. After observing their club activities and individual training, I also realized that being a teacher for special school requires much more patience compared to teachers in normal schools. Regardless of their additional knowledge, they have to deal with special kids, teachers have the patience I can’t image when facing endless incidents made by kids. I kept thinking about how to help the teacher to teach kids with more focus and easier for students to follow. For example, the African drum could actually be turned into a game for students to train their focus. We could set a sensor in the teacher’s drum to detect when the teacher bangs the drum, and send this signal to students’ drums with LEDs. So students will receive sound and visual inputs to ask them to also bang the drums, and I guess that could improve student’s focus.
  • Describe your project idea (individual)
    • Describe your partner as a person (not PwD)
      • He is a 30-year old male who loves playing computer games and using the computer to search for knowledge(e.g. how to take public transportation from home to NYU Shanghai). 
    • What are their desires/challenges/difficulties?
      • As he is deaf and cerebral palsy, he has difficulty in communicating with people. Actually, during our first conversation with him, the conversation was basically dominated by his mother who is quite talkative. So we found that communication is the problem we need to help him to solve.
    • What is your project? 1 paragraph description + Photos + Videos
      • We want to build a portable electronic writing board for him to carry on wherever he goes. The board should be easy for him to write, and easy for other people to read, and write him back. Additionally, it should be easily erased, so that’s why we don’t use a traditional writing board.
