Duet had many sources of inspiration, partially in class projects and outside ideas. Initially, the group project, which consisted on a futuristic sensory machine that read your emotions, had an important role in the original idea. Due to the importance of the sensors in the first project, we had decided that the main idea had to implement sensors. Yet, during the brainstorming period professor Marcela changed our minds. She urged us to think not only of the machine but the experience that the machine was trying to achieve. For that reason the project took a turn, we thought of the water fountain project that talks, and the virtual ping pong game that worked with sound. Those projects helped us change our view, and come up with something new and exiting. The idea had influence from the dance machines, and the ping pong game, the idea was to create a dance floor which had to be used by two competitors to finish a sequence. Yet, because of the materials available to us we did not pursue a dance floor, due to its fragility and danger that it posed. Nevertheless, we created to boxes that lit up in a determined sequence, for the player to memorize and copy. The main objective of the project was for the audience to play between each other and try to beat the game, having friends compete between each other to complete the objective.
The decision of going for boxes instead of a dance floor was a practical choice. Because of the problems of size and fragility that a dance floor would pose. We also chose to use copper paper due to its conductive properties and fabricate the boxes for esthetic purposes. We circulated around the idea of covering the boxes with a color paper to make it more appealing, but we finally decided against it because of fear that the paper would diminish the conductivity of the machine. The way in which we decided the way we were going to interact with the machine was simple, using the same concept of a Makey-Makey we decided to interact with the machine by closing a circuit. Nevertheless, I think the concept might have not been clear enough to the public. Although, it had instructions in the computer the audience seemed confused by it.
The fabrication was not as simple as firstly imagined, we used an online design to laser cut the boxes with teeth so they could be jacked together. Afterwards, we had to figure out how to connect the boxes so they could sense ground when touched. For that we had to use a transistor, and two types of resistors(1w and 220w). We also connected a wire to the boxes and the copper paper so that when touched the machine would sense the person. The fault in the design was the lack of strength that the paper, the fragility of copper paper should have been addressed before presenting the project. In one hand the project problems with its fragility, and on the other hand it did work in the sense that it could sense the contact with the people. It also had feedback when done correctly and when done wrong. Yet, some people were not completely sure how the mechanics worked rendering the project somehow hard to use.
The project had the vision of making people interact in a fun way between each other, helping them deepen ties of friendship. The project was designed to be interactive in many different levels. The project tried to make people interact with each other by making them compete. It also, interacted between the user and the machine, which send feedback each time used correctly or incorrectly. I think it did not fulfill all the requirements for interactivity, because it was too confusing to the user, but it tried its best to be clear without many words. I think with more time I would have created a more resistant lid that wouldn’t be cut so easily. Also, try to make the code more clear, maybe by printing instructions as the professor suggested. And finally, make the boxes more pleasing to the eye. The project taught me that sometime we fail to acknowledge faults in our designs, or ignore them because we think that everyone is like us. But, that is not the case and some people understand the concept behind what we did and others didn’t showing us that we failed in the part of clarity. This project is very important because it demonstrated how sometime we are what we want and not what others see.
