Im running a paradigm in which participants make a response based on the position of one or more images on screen. How do I simulate a response based on the activity of one or more screen regions?
The kit can monitor for up to four active screen regions. By programming DSCAR (Digital Stimulus Capture And Response) the kit can be instructed to react to activity on any of the four regions by means of the OR function. Alternatively patterns of activity can be ANDd together to provide for addition functionality. For example in the OR condition you could use two opto-detectors to monitor for top right OR bottom right and simulate an Active Switch Closure that closed a button on your response device. Stimulus images appearing at either OR positions would trigger a simulated response. In the AND condition if using the same two positions then both bitmaps must be visible simultaneously before a simulated response is triggered.
