Joystick update rate?

[farshizzo]

If you look in the __update function of the joystick class, you'll see that it simply polls the state of the buttons. You could create a thread that polls the joystick button state at a higher rate. However, I'm not sure this method will provide enough accuracy for your experiment.

I've heard of some software that allows you to map a joystick button to a keyboard press. I don't know exactly how they work, so they might end up adding even more latency.

Vizard supports Cedrus response pads, which are made for reaction timing experiments. You might want to look into this.
