[newRPL] What do we use touch for?

[Claudio L.]

Lots of interesting ideas!
I guess what I need to work on first is some kind of framework to detect those gestures. For example, how do you know you are swiping from outside the screen and not pressing right at the edge of the screen, then dragging?
I'm going to try to distinguish them based on the speed of the finger when it enters the touchscreen (I imagine if you are swiping from outside the edge your finger is already at speed, while if you touch and move I should be able to see the acceleration of the finger), but I'm not sure how well it will work in real world scenarios.
