Time accuracy - need help for pilot research
I am a cognitive scientist researching how people interpret alarm signals during stress, and in doing this I am thinking of using Flash MX 2004.
I need to develop a fullscreen application that shows colored circles and lets the user choose between the two circles each time a new pair of circles appear. Sounds like fun huh? Well this research will probably help pilots in emergency situations, so please hang in there =).
The problem is this: I need the application to be extremely time accurate, it has to log the users keystrokes and show colored circles with millisecond precision. Well, it can be off by a few milliseconds, but if its off by 30 ms or more, its not good, and pilots will crash all the time =).
In more detail, this is what the application must master:
* Show two colored circles (on to the left and one to the right) and sound the corresponding alarm sounds (left and right headphones), at the exact same time. This is crusial, since the user CANNOT notice any time difference between the circles or sounds.
* Log the time from the appearance of the circles and sound, till the user presses a key (chooses any of the two circles). This doesnt need to be as time accurate as the above one, I just need to see that the user doesn't have any strategies.
I am grateful for any help!
