The solution to all your digital event marking problems

Born to Mark
StimTracker analog to digital stimulus event markerStimTracker 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.
Mark Anything
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:
  • Up to four photosensors
  • Voice key
  • Two audio channels
  • Six TTL inputs
The amount of information available to you depends only on how many input lines your equipment can handle.
An Eye For Stimuli
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.
