I just published a short video that shows how a cheap contact microphone can be used to recognize different types of fingers touch and transform any surface into an interactive board. Users can train the software with their own ‘gestures’, using both bare hands and objects. In the video demo we put the microphone over different surfaces such as kitchen tables and balloons. The sound synthesis is based on two different techniques:
1 - physical modeling, which consists in generating the sound by simulating physical laws. Different materials can be simulated, such as membranes, strings, tubes and plates
2 – mosaicing, that works as follow: first, users load a sound folder; then, the noise coming from the microphone is analysed and the software continuously finds and plays its closest segment within the sound folder.
