Can this techincally work? (Score 1)

I have a question about the feasibility of the design. As I understand the video a user rests their hands on the 10gui input device and the capacitive sensor detects the positions of those ten fingers. Pretty normal multitouch so far. Where the 10gui design is innovative is the combination of the resistive layer to detect 'clicks'. If you watch the video at 5 minutes you'll see what I'm talking about and where I'd like to understand how this is being done. The problem is, you cannot detect multiple presses with a resistive layer - that's a basic limitation of that tech and no way around it afaik. My initial reaction to this was to think 'hey, this is just a concept for now, lets look in to the boring details later' so I went back and did some research on the other multiple touch sensor technologies and found a very interesting problem. A very fundamental problem too! Take a look at this video http://cs.nyu.edu/~jhan/ftirsense/ So, all the other multitouch sensors are optical - That I've found, and I would dearly love to be corrected! - are optical. So the fundamental problem is how do you 'see' the difference between a user resting their fingers on a surface and the user pressing down on the surface. You need to use two very different technologies - as 10gui proposes. But, all the other technologies are single touch only. I use a multitouch sensor for my desktop (wacom bamboo 8x5) and it is tiring as hell to hover your hands above the input device. The only way these device will work is as demoed in the video. However, I dont think its technically possible.
