We are trying to make an android/ipad app that will test reaction times in autistic kids. I have a prototype application that can do pretty much everything that we want in terms of stimulus presentation and event triggering however the touch events seemed to be linked to the framerate which gives us a temporal resolution at best at 16 ms (at 60fps), which is not enough for the time differences we are trying to measure. Is there a way to speed up the framerate or change the behavior of the event trigger to a more interrupt based method rather than the current frame based method. If this problem can be fixed then corona can potentially see a very large medical application. Thanks in advance.

you can use time probably?

Basically, note the time when stimulus is presented, then when you register your touch event note the time (event.time) and measure diff?

unfortunately thats exactly what we are doing but the event.time gets discretized to the framerate ie... event.time can only read 16 ms, 32 ms, 48 ms... which gives us only 16ms of time resolution :o(... I wonder if there is a hardware timer we can use from corona or is it too "sandbox" to use such low level facilities. Any ideas?
