Eye Tracking Technology
Part #: EYE-TRACK-BAR-00, EYE-TRACK-BAR-01, EYE-TRACK-BAR-02, EYE-TRACK-BAR-03

This mini screen-based remote eye tracking bar provides gaze position, dwell time, blink rate, pupil size, and more. Use with an AcqKnowledge Eye Tracking Integration License (ACK100W-EYE) to access valuable eye tracking metrics: Gaze Path, Gaze Plot, Heat Map, and Attention Map. Create user-defined Areas of Interest (AOI) and select Scarf Plot, String Plot, Pie Chart, and Key Performance Indicator (KPI) metrics. For concurrent physiological data such as Heart Rate, EDA, SCR/SCL, etc., record biometrics from a Wireless Smart Center, MP160, or MP36R Research System.

The unique dark pupil technology of these EyeTech Eye Tracking Bars enables real-time eye tracking on any computer screen. Since the system uses an infrared camera and provides its own light source, you can track in a variety of lighting conditions.

Eye Tracking data delivers meaningful insight for studies in Psychology, Consumer Marketing, Market Research, Training, Vehicle Simulation, Advertising, Design, UX/UI, Usability, and more!

Choose system based on “Hz” level. Higher frequency rates have lower latency and provide more data, which increases accuracy for Microsaccadic Eye Movements, Fixation, Blinks, and Pupil size data.  Lower latency also improves data alignment between eye tracking data and physiological data.

Compatibility


The bars use two infrared light sources and a single camera. The IR lights illuminate the eyes and provide reference points for the eye tracker and the single camera does both single and binocular eye tracking. Two “glints” appear on the pupil of the user’s eye from the IR light sources, and after a short calibration, the camera is able to know when and where the user looks. If two people are in front of the camera at the same time, it will only track the first person found by the camera.

The remote bar works well with most glasses and contacts.

  • Hard-transition bi-focal glasses can cause problems; it is recommended the user upgrade to progressive bi-focal lenses if bi-focals are required.
  • Hard contacts can also cause problems; it is recommended that the user wear soft contacts if contacts are required. The IR light is produced by LED’s at a wavelength of 850 nanometers.

Eye Tracking bars are also compatible with Microsoft Eye Control.

Place the eye tracker directly below the monitor with a magnetic strip or mount directly to the monitor using a VESA compatible mounting bracket or use the flexible desktop stand; the desktop stand allows for greater adjustment of tilt and makes it easier for people of different heights to be tracked.

This type of IR light occurs naturally in sunlight and in light from incandescent lamps. The IR light intensity at the user’s eye is less than is often experienced by most people during their daily activities. This is also well within the safety guidelines given in the book 2007 TLVs and BEIs by the American Conference of Governmental Industrial Hygienists.

EYE-TRACK-BAR has a 2-year hardware warranty.
