Hi all,<div>I'm currently trying to input data from two force transducers into E-prime so that it will display on the screen in real time. The task is a pursuit tracking task where a subject is using a finger force to trace a line that goes up and down as it progresses across the screen. I'd like to be able to display the force as a cursor or a line across the screen in real time. The force transducers are input through a National Instruments box into the USB port on my laptop. I've tried adding a port, and I've tried adding a joystick to the devices, but I can't figure out how to tell E-Prime what to do with the USB input. There should be 12 inputs, the xyz magnitudes of each force, and the xyz torques of each force. I'd only need to plot one of them, the z magnitude, but I'm not sure how to tell E-prime that. Which device should I use, and if I need to do some visual basic coding which functions should I start with?</div><div><br></div><div>I hope that makes sense.</div><div>Thanks,</div><div>Bree</div>
