Piezo and gesture recognition …

Yesterday, Ludovic and I managed the Piezo microphone. The Piezo is our sensor for motion recognition, on our metalic surfaces. We have 2 piezos, and 2 metalic “tables”. The first one for the Waiter, and the other for the bartender. The piezos are connected to an external sound card.

We recognise 4 sounds/ gestures, on our “Multitouch” table :

  • Scratching 
  • Tapping
  • Knock
  • “BAM”
These gestures were recognized with a Pure Data patch.
