Video Eyetracker Toolbox™

The Video Eyetracker Toolbox™ allows you to easily add eye tracking to experiments where the display is a computer monitor.

The Video Eyetracker itself is mounted on a rigid EyeLock™ headrest that incorporates the camera, illumination and optics. The Toolbox functions provide a kind of 'eye tracker engine' that can be used with almost any Windows programming environment to integrate gaze tracking or fixation monitoring with your existing laboratory software.

In many cases, however, no programming is required, as the The Video Eyetracker Toolbox™ is compatible with GazeTracker™: a powerful software package that consolidates stimulus presentation, information synchronisation, data analysis and visualisation. Gazetracker is not part of the Video Eyetracker Toolbox, but a special package price is available when they are purchased together.

We also offer a custom table to which the Eyelock headrest can be firmly mounted, with space for 21" computer monitor at a wide range of viewing distances. The ergonomic offset table arrangement comfortably accommodates the subject while viewing the stimulus monitor. The powered table lift augments the headrest adjustments to ensure complete subject comfort.

And, of course, our Video Eyetracker Toolbox integrates with our ViSaGe visual stimulus generator, so that gaze contingent stimili are no problem.

The system has been designed for vision scientists and experimental psychologists, and includes facilities which they themselves requested.

• Exceptionally easy to use with minimal configuration requirements
• Very low cost (the entry level system configuration is less than £6000/US$11000/€10000)
• Measures gaze direction or eye rotation

Sophisticated image processing algorithm:

• Intelligent, adaptive and extremely robust to lighting conditions and variations
in individual subjects
• Knowledge Based recognition of image features
• Predictive algorithm uses prior measurements
• No operator adjustments of thresholds are required

Extremely rigid EyeLock™ head + chin rest. Includes integrated:

• IR camera
• IR illumination
• Dichroic mirror
• Ambient light shade

• Transparently controls hardware, performs calibration and acquires eye position data

Data is available in the following real-time forms:

• X-Y eye position at a specified frequency
• X-Y velocity

• Triggers based upon thresholding any of the data forms
• Integrates with the ViSaGe visual stimulus generator or dual VGA display for stimulus display

Applications

Fixation monitoring

• Ensure the subject maintains steady attention to a visual stimulus

Visual scanning & reading experiments

• The Toolbox is a perfect solution for developing software to examine reading and visual scanning. Its wide range and accuracy are ideal for measuring fixation patterns.

Gaze contingent displays

• A close integration between the Toolbox and the ViSaGe visual stimulus generator simplifies the implementation of eye contingent displays
• The stimulus position can be readily modified based upon subject fixation

Oculomotor Research

• When a precise knowledge of fast eye movement dynamics is not required, the Eyetracker Toolbox is suitable for a wide range of eye movement recording applications
• For example: smooth pursuit studies

Oculomotor behaviour monitoring

• For experimental paradigms that involve subject eye movements, eye position can be synchronously monitored with the stimulus presentation and feedback provided of subject compliance
