Microsoft shows off five multitouch computer mouse concepts:
Microsoft is apparently looking into expanding its multitouch support, as it's doing with Windows 7, but of course....the user needs a way to take advantage of that technology, obviously. So to that end, Microsoft is exploring another avenue to help proliferate multitouch: new computer mice.
The five designs you see in the video below aren't final products. They're concepts and show the direction Microsoft is going with the idea. The mice use everything from IR-sensitive cameras to capacitive-sensing electrodes.
Now, the one particular mouse that I and I am sure some of you here will find of interest, is the one called "Orb Mouse". On the YouTube video link below, there's a demonstration use of the Orb Mouse on a FPS game you just got to see, it's the 3rd mouse on the video: http://www.youtube.com/watch?v=-3PZkpQThek&feature=player_embedded
