I am getting ready to use DirectRT in conjunction with a joystick. Basically, we want to measure the speed with which participants pull the joystick towards or away from themselves in response to certain stimuli. I haven’t purchased a joystick yet, and I was wondering if there were any guidelines for buying a joystick that will interface with DirectRT?

A colleague told me that he uses a Logitech Wingman joystick with DirectRT to measure response times (in fact, we are borrowing his DirectRT program), but Logitech doesn’t seem to make that version anymore. Some of the newer versions have lots of buttons or are wireless. Will a wireless joystick be able to measure RTs with the same precision? Will extra buttons be problematic?
