Hi Hal: There has been some recent research into illusions related to sight and sound. https://en.wikipedia.org/wiki/McGurk_effect - related to speech and search "audio optical illusion"
I like a crisp "tick" for clock human synchronization. I wonder why there has not been more done with military "Have Quick" for time synchronization? https://en.wikipedia.org/wiki/HAVE_QUICK It's been a part of the PLGR and DAGR GPS receivers and I expect also for the military embedded versions for a long time. https://prc68.com/I/PLGR.shtml#Time https://prc68.com/I/DAGR.shtml#HQ1PPS Also things like the O-1814/GRC-206 Reference Frequency Rb Oscillator make us of it. https://prc68.com/I/O1814.shtml -- Have Fun, Brooke Clarke https://www.PRC68.com axioms: 1.

Does anybody have numbers for how long it takes for a visual signal to get into your brain? I think it's around 250 ms for a human to push a button when a light goes on. Less if the penalty for false pushes is low. I don't have a handy URL to back that up. But that's in and back out. I assume the "in" step is only part of that. Are flashes out of the corner of your eye that might indicate danger faster? If 2 lights go on at close to the same time, how far apart do they have to be before you can notice that one goes on first?
