Mic turns any surface into a touch interface

A new contact microphone, when connected to a system, is able to process sound in real time and turn any rigid surface into a touch interface.

'Mogees' is an interactive gestural based surface for real time audio mosaicing. In this video gesture recognition is performed with contact microphones that enable any surface to be transformed into an interactive board. Two audio synthesis techniques are used: Physic modelling, which consists in generating sound by simulating physical laws; and Concatenative synthesis (audio mosaicing) in which the sound of the contact microphone is associated with its closest frame present in a sound database. The system can recognise both fingers-touches and objects that emit a sound, such as the coin shown in the video.

Mogees has been developed by Bruno Zamborlin in collaboration with Norbert Schnell.
