30 ms delay is noticeable (Score 1)

The article states "Finally, the system relays its positional information to the console in fewer than 30 milliseconds, Mahajan says, adding that this is faster than the human ability to perceive delay." Musicians who have used multitracking recording software on a computer with stock drivers know that 30 ms latency is not only perceivable, but unacceptably long. The solution is to use ASIO drivers, which deliver a truly unnoticeable 4ms latency. I'm sure 30ms is fine for a golf club swing, but it isn't negligible under some circumstances.
