[sdiy] Polyphonic touch panels?

[Veronica Merryfield]

Yes, capacitive. A number of cap touch vendors have multi-touch solutions. 

One can do multi-touch with resistive sensing too but is harder. Typically, you have to divide the pad into an array but one can sense two of three touches with a regular touch sensor.

iPhone and iPad are multi touch and I think it is up to five touches.
