Difference between 100ms and 1ms

Microsoft Research compares varying interaction latencies with current and future touch screens. I don’t enjoy drawing on current 100ms delay touch screens, but when we get to 1ms, I’ll be drawing all the time.

Modern touch devices allow one to interact with virtual objects. However, there is a substantial delay between when a finger moves and the display responds. Microsoft researchers, Albert Ng and Paul Dietz, have built a laboratory test system that allows us to experience the impact of different latencies on the user experience. The results help us to understand how far we still have to go in improving touch performance.
