tesp 2012 drums haptic interface
DESCRIPTION
Few days Arduino based project to develop sound (frequency) dependent haptic interface for simulated instruments on touch-screen devices like tablets or phones. Input is simply the audio signal. Could be expanded to real instruments for the enhancement of the feeling by using a microphone.TRANSCRIPT
