Touch sensitive blackboard
Touch sensitive surface using a single sensor only. In general one needs as many sensors as dimensions for positioning, e.g. GPS needs at least 4 satellites to find the 3D position + time. Here 2D positioning is done using only a single sensor - a simple PC microphone.This video is based on a project done at the Group for Digital Signal Processing and Image Analysis, http://www.ifi.uio.no/research... Department of Informatics, University of Oslo in the course INF3460 - Project in acoustics and signal processing, http://www.uio.no/studier/emne...

For those considering buying a new vehicle, don't forget to check out
the new 2008 Toyota FJ Cruiser. Great for adventures off road, just for
cruising around town, or running to the store.
The new 2008 Toyota FJ Cruiser seats five and comes in
two-tone with a Voodoo Blue, Titanium Metallic, Black Diamond, Sun
Fusion, Sandstorm or Brick body color and White top. The interior
fabric color is Dark Charcoal, while the dash, center instrument panel
trim and the door inserts match the body.
