Tangible Acoustic Interfaces for Computer-Human Interaction
Alternative for video tracking systems.
Interesting project about tracking sound for Computer Interaction. The project name is Taichi, developed in UK.
I see a big advantage in having the possibility of using a very durable and cheap surface to interact with. On the other hand, I would like to know how much sound do we have to produce on the surface in order to have an accurate tracking.
