Solving the touchscreen delay problem
Microsoft’s Applied Sciences Group is working on new technologies that improve touchscreen input response time:
One of the biggest problems with touch interfaces is simulating physics well enough to fool the brain’s perception systems. When a physical action you make with your finger does not lead to the response your brain has learned to expect in the physical world, something feels very wrong. It doesn’t feel genuine. Thankfully, Windows Phone does a much better job at this than Android; Microsoft is clearly thinking about this stuff.
