Multitouch using water
posted Jun 26th 2010 4:55am by Caleb Kraftfiled under: multitouch hacks
[Taichi Inoue] is back again, this time with a multitouch system that uses water as the touch surface. The setup consists of a tank of water placed atop an LCD, a lamp, and a web cam. The web cam pics up the light that is reflected when something breaks the surface of the water. It is, as far as the computer is concerned, no different than the blob recognition we see with many of the home made multitouch systems. Mixed with his Yukikaze, this guy might end up with the most relaxing computer system in the world.

Lol HAD read my mind! I am building the webcam picture frame multi-touch this afternoon with a friend :) This is so very cool as well! Good work Taichi! I guess this is next weekend’s project :)
While we are here, can anyone suggest a pretty easy method of getting usb wirelessly to the HTPC? I am putting the webcam mouse thingy in the coffee table and would rather not run usb extenders if possible. I know it is a simple duh problem to must of you, so give me some NON-arduino/STAMP or Xbee suggestions please. I may just end up trying it out with a bluetooth webcam my friend has, but have no idea how well this will work. Thanks for any ideas :)
