Ward Technical Consulting    ...an eye to the future.

The Dual-Purkinje-Image (DPI) Eyetracker is the number one choice in non-invasive Eyetrackers for both spacial accuracy and temporal response.  A world-standard research instrument that determines the direction of gaze over a large two-dimensional visual field with great accuracy,  it operates with infrared light which is invisible to the subject and does not interfere with normal vision.  The Generation 6.6 DPI Eyetracker has a pointing accuracy on the order of one minute of arc, and response time on the order of one millisecond.  The output is sampled at ~4 kHz!  You can also add our Infrared Optometer to allow a continuous measure of eye accommodation producing a 3-D Eyetracker.

 

The DPI Eyetracker is the finest research instrument of its kind available today.  It is compact, easy to use, fast and extremely accurate.  At present, Wardelex offers two Eyetracker models-  one is our top-of-the-line Generation 6.6 DPI Eyetracker, and the other is the DPI Eyetracker 2000, which has slightly different specifications and a few less options than our Generation 6.6 model.   The output data is the cleanest and most linear in the industry!

 

The DPI Eyetrackers may be ordered as single systems (monocular) or as binocular systems (two separate Eyetrackers -- one for each eye).  Options for the Eyetracker are available for all models- Optometer, Stimulus Deflector, Scotoma Device, and FIMI.
