sensor and interface information

The sensors i'm using will be flex and pressure sensor.  The way the the user interacts with the project will be through simple finger motion and pressure between the thumb and the other finger(s).  The idea is that the videos will cycle based upon the flex of the fingers, and by flexing the fingers other then the pointer finger it will change either the sound or the effects that are happening to the video.  It will be using a few preset videos and sound data.
