28th + 30th September 2009
IDC, Chalmers University of Technology and University of Gothenburg as part of the Physical Computing course
Gothenburg, Sweden

During this 2 days hands-on workshop, we will build a wearable game interface for classic video games. Participants will experience basic fabric electronics technique. We will experiment with construction of various fabric sensors, relationship between placement of sensors and body movement/interaction scheme. These hand made sensors will be connected with hacked gamepad, either simply extending the on/off switch or by using Arduino and mosfet as switch.

*Unfortunately MOSFET switch did not work for all the groups. If you use more than 1 MOSFET on the buttons that is shearing same power (but divided), it interferes each other. To avoid this, we used analog relay instead. Also, some groups found out that a register next to left direction button had to be removed and replaced, otherwise it gives false left direction signal constantly. (>> If someone knows more about it, please make a comment)
