  1. Great summary of meaningful latencies. I think it would have been nice to include human reaction to in 100-200 ms range. This is the minimum time humans need to actually react any new information, not matter how little semantics that information contains. An example would be ability to press a mouse button after something appears on the screen. Another good latency to include would have been 10-20 ms for the minimum time to get something on the screen on most computers.
