 I have been asked about my contribution to Multi Touch technology when I worked at Microsoft Research.
I have been working on multitouch user interfaces  since 1982, designing music synthesisers and  other keyboards. In those days, engineers referred to multitouch as "polyphonic" when describing the keyboard scanning.    In
2003 , I wrote a paper  on a new type of optical touch sensing , click here. * My co-researcher on this project at Microsoft Research was James Srinivasan.  The project was called SmartSkin, it was a working prototype  and used optical sensors to detect multiple fingers and shadows from hands. It used Light Emitting Diodes to display pixels . When  a LED is reverse biased, it can detect light, e.g. the proximity of a finger. The Paper gives references to other  companies working on this technology.  The paper also describes low cost optical methods of motion detection without the use of accelerometers.
 Microsoft did not patent SmartSkin, so the algorithms , schematics and software in the paper are in the public domain.
Here is a video of another of my Microsoft touch sensitive screen innovations, GyroTablet. 
My latest work on Multitouch is SenseSurface
