Really. Worry no more about stripping or splicing cables. StimTracker comes with everything you need to connect to EEG/ERP recorders and eye trackers.
Your EEG or eye tracker data is vastly more useful if it includes markers that tell you precisely when certain events occurred. Except for codes sent via USB, the onset of events is detected
autonomously by StimTracker, allowing it avoid delays incurred by operating systems and produce accurate markers.
Onset of Visual Stimuli
Use the included fast light sensors to avoid operating system delays and detect onset of visual stimuli with precision.
Onset of Auditory Stimuli
Pass the audio output via StimTracker, set the threshold, and let it do the rest.
Onset of Participant Response
Or any external TTL signal.
Event Codes via USB
Send event codes from your stimulus presentation computer for added information.
Onset of Vocal Response
Plug a PC-compatible microphone. Get a free voice key device.
When using a version of StimTracker that supports an eye tracker, event markers can also go out simultaneously to any of the supported EEG models. This guarantees that both sets of data are using the same timebase — an important criterion when analyzing the data.
To insure the repeatability that rigorous research requires and to prevent accidental changes, we made the controls 100% digital — and even easier to use.
We built and tested several prototypes before settling on a light sensor that offered the optimum balance of speed and light frequency response. Then we designed and built our own tiny housing that is unobtrusive and practical to use.
StimTracker has all the electronics needed to detect the onset of events and produce markers. But software can also send event codes via USB, e.g. to describe the trial being presented or whether the participant’s response was correct.
We provide E-Basic code example
Built-in support in version 4.0.3 or later
Built-in support in version 14.8 or later
The commands that StimTracker accepts are public. Published Python and C++ code libraries that support our response pads are easily adapted for sending event codes to StimTracker.
Eye Tracker Support
Another output connector appear here on StimTracker models designed for eye tracker support
Use up to four light sensors for precisely marking the onset of visual stimuli
Plug & Play Event Markers
Insert one of our signal adapters here and your markers are 100% ready for delivery to data acquisition system
Six lines or TTL input that are passed through StimTracker to the output
Use any PC microphone
Connect stimulus presentation computer via USB
Pass the audio through StimTracker. It will monitor the audio level and produce an event marker for either left or right channel
