Recitation: User Testing

    I remembered that there is one project requiring me to move different trash bins to catch the rubbish of different categories. But the rubbish bins and sensors are placed on two heights. So whenever I try to move the rubbish bin, it makes me feel a little bit uncomfortable because I need to lift it up, and it will slow down my pace, thus influencing my playing experience. So my suggestion is to connect the track for the sensors with the original position of the rubbish bins. This can make the project more looks like a whole and the process of moving to a different position is quite smooth as well. I think the concept is really interesting. Shanghai now is using trash classification to recycle more things so that the city can be more environmentally friendly. While one big problem in our dorm is that some foreign students and some students coming from other provinces, may have a different standard on rubbish classification. So it is quite interesting and meaningful for them to know the rule in Shanghai by playing a game like this. The technology is using sensors which can detect the light I think. When the trash bin is removed from its original place, the sensor will detect the light and then send feedback to the computer. This is quite interesting because we cannot see the sensors at the first glance and the interaction process is user-friendly as well.

    For my project, I think I mainly receive 3 suggestions. The first is to make the screen bigger. The second is to add a save button allowing users to save the image. The third is to debug the OpenCV since it sometimes regards something else as one’s head. I think the least helpful one is the last. Because it’s a problem of OpenCV itself and it’s a library we downloaded from GitHub. I don’t think I have the ability to improve it yet. But we do try other things, for example, making the background clean to reduce the chance that there will be a bug. The first and second are quite helpful. And these are the two things we have been working on after the user test. We add a save button allowing users to save their image as something with a memorial meaning. And in order to keep an appropriate frame rate, we work with Eric to do the calculation on a smaller screen, meanwhile showing it on a large screen. Those suggestions all make the project more user-friendly and makes the process more joyful. Another one is raised by ourselves, we try to make the best use of the table. By re-organizing the position of the project, we create more space for the users to move, so that they could have a better experience.
