Reflection:
The first thing I learned during the processing is that the processing page shows an error and we can not find any mistake of the content, we can check if the position of brace is correct. Another is that we can map in the Arduino. In the processing, sometimes we may come across some unknown problem with mapping. After reading Golan Levin’s essay, I gain a different perspective of the whole-body interaction. At first, we want to use a balance board and add sensors to that board to transfer input. While the example of “Interaction modules from Myron Krueger’s Videoplace, 1969-­1975″ inspires me that we can install sensors to our body to trace our movements and transfer them to the computer directly. If we add the sensors to the balance board, it may overreact because some of our movements are out of balance. If may hard to use the balance board to send instructions.
