StimTracker

StimTracker was created with mainly one purpose: sending event markers. And making it trivially easy to do so. So easy, in fact, that StimTracker is born ready to connect to a variety of EEG/ERP recording devices (see sidebar) and a PC's parallel port. You no longer need to worry about incompatible connectors, pin assignments, and custom cables -- it's done for you.

It is common to send event markers from the stimulus presentation computer to a recording device. StimTracker provides a USB port for this purpose, but it can also handle a complete range of events:

Unable to find a photosensor that is unobtrusive, easy to mount, and fast, we set out to build our own. After the initial vetting, we put six electronic photosensors through a rigorous selection process. Then we designed a tiny plastic housing (just 8 by 14 mm) and built the necessary mold. The result? Just peel and attach to the screen.

To make the Cedrus Photosensor even less distracting to participants, we offer it in black and in white, the two background colors most commonly used in experiments.
 

Via the innovative use of adapter kits, StimTracker comes ready to connect and be used with recording devices from these manufacturers:
