Touch me is a interactive installation as projection for multiple users. People stare at the same artwork but rarely have conversation. The installation is aim to provide interactive experience among people in the same space. Here is how things goes : Everyone have a bracelet as wireless sensor and since they touch each other , a patter would appear on the projection. patterns come from different combinations between any two of users.
I decide to hack a keyboard to make my own sensor , since I can read a data like key pressed event , I can easily deal with most code can make the installation work.So I go to ChinaTown to buy a used keyboard and disassemble it.
I am really exciting because it’s a chance to know how keyboard works. In general , there are two layers of conductive map connect to two section of pins on the micro-comtroller.The first step would be I scraped off the coating with a razor blade and test the combination of pins.
Then I soldered them and connect to PCB , extended wires to make sensors.
