StimTracker

Make Sense of Your Biometric Data

Mark Events Sync Recorders in Multimodal Research

Why?

The biometric data that you collect, e.g. from EEG or eye tracker, is vastly more useful when it includes markers that tell you exactly when certain events occurred.

StimTracker can detect the onset of these events and send them to several recorders simultaneously.

Types of Events

StimTracker detects the onset of events in behavioral research, and does so autonomously to avoid operating system delays; see also StimTracker Duo vs. Quad.

Onset of Visual Stimuli

Fast light sensors included.

Onset of Key Response

Connect a response pad to mark participants’ input.

Onset of External Events

Connect switches or TTL signals (Quad only).

Onset of Auditory Stimuli

Play audio via StimTracker and let it do the rest.

Onset of Vocal Response

It’s like getting a free voice key device (Quad only).

Event Codes via USB

Send event codes from your stimulus software.

Plug-and-Play Output

StimTracker uses m–pod to deliver its signals. This augments StimTracker’s capabilities and provides compatibility with a wide range of recorders:

Jitter Free USB

When sending event markers via USB, StimTracker delivers them with jitter free precision when used with SuperLab 6 or with our open source Python or C++ libraries.

Delay is guaranteed to be 2ms exactly, every time.

Asynchronous Output

A powerful 32-bit microprocessor running our software lets StimTracker send event markers via USB asynchronously. Without this feature, software that wants to send a 10ms long event marker has to pause execution for 10ms. In neuropsychology, psychophysiology, and other fields, this is too long of a pause. With StimTracker, the software sends a command and resumes other time-sensitive tasks – no pausing. 

There are other powerful features such as a pulse scheduler and pattern generator;
see Specifications.

StimTracker has built-in signal filtering.

Signal Filtering

Some audio stimuli are computer generated tones. Others are recorded words or sentences. Visual stimuli vary as well, as do the displays being used to present them. StimTracker includes powerful filtering options to handle all sorts of signals. Cedrus provides free software for setting the filter values, which StimTracker then stores in its flash memory.

Software Support

StimTracker enjoys extensive software support. Some packages can deliver jitter free performance.

Jitter Free

  • SuperLab 6
    It’s a free upgrade to all SuperLab 5 users.
  • Inquisit
  • Python Library
  • C++ Library

Others

  • E-Prime
    We offer an E-Basic code sample. Precision is about ±5ms.
  • Presentation
    Built-in support. Precision is about ±5ms.
  • Matlab
    We offer a Matlab code sample. Precision is about ±5ms.

Wireless Option

Cedrus worked closely with CGX Systems (formerly Cognionics) to develop an integrated solution. The result, Wireless StimTrigger, allows you to send event markers wirelessly and with high timing precision to all currently shipping CGX EEG devices. Wireless StimTrigger is available directly from CGX.
