eye tracking hardware placed on driver-side dash behind steering wheel

Historically, the most common use of eye-tracking systems has been to evaluate static displays such as signs or web pages as viewed by stationary subjects. Eye-tracking in a vehicle allows TTI researchers to remotely determine metrics such as glance position, glance frequency, and pupil diameter without affixing equipment to the participant. Both the FaceLAB® and Fovio are portable and provide freedom of movement for the subject. This allows for the collection and examination of real time eye behaviors while driving, both in the simulator and in the field. The EyeWorks™ software provides analytical tools to quickly process eye glance data and identify regions of interest in the visual scene to automatically tabulate glances to those locations.

Equipment

Fovio Eye Tracking System

TTI uses the Fovio eye tracking and driver monitoring system for on-road and closed-course studies. This low-profile enclosed system mounts inconspicuously on the dashboard. It offer fast calibration for research subjects and improved eye tracking for nighttime studies.

FaceLAB® Eye Tracking System

FaceLAB® employs two dashboard cameras and an infrared emitter to detect a driver’s eyes. TTI operates two FaceLAB eye trackers to allow for concurrent research projects or the two systems can be coupled to allow up to four cameras to capture 180 degrees of head movement.
