Hi,
so I happen to know a trackpad that is truly awesome. It looks a bit like the apple magic trackpad but instead of having a conductive sensor it has light sensors in a frame on top of the glas surface, meaning that all kind of different pointing devices are possible to be used. You can even use it with gloves on.
A similar product can be found here
http://optapad.com/en/ but that product have hand rests, buttons etc.
I'm curious about what the interest should be of releasing such trackpads, with an open source firmware and hardware design open. You would be able to order it, and then hack away to build a truly ergonomic trackpad of your liking. For example integrate it into a kinesis advantage.
What are your thought? Should a make a massdrop for this? Or perhaps a kickstarter?
