Hi David,<div>Thanks for your input, I wish I would have asked you this questions before purchasing E-Prime as I explained my task specifically to them and they assured me that it would be possible. I wish I hadn't wasted my limited budget. Thanks for the help.</div>

First of all, this looks like a fine example of a task particularly ill-suited to E-Prime. You might well find a better platform for this task. And since you say you use a National Instruments box, you might start by looking at their LabVIEW software.<br>
<br>
But if you must proceed with EP, then I would ask, doesn't the National Instrumtents box come with a library of functions in a .dll file? If so, then you merely have to make those functions available to EP through the appropriate Declare statements, and that should all be documented by National Instruments. As you should have figured out by now, EP does not provide any native support for USB communication (and if we understood more about USB, then we might understand why not).<br>

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?<br>
<br>
I hope that makes sense.<br>
Thanks,<br>
Bree<br>
