VisionTrak enables a subject to have full head and eye range of motion while it simultaneously collects eye movement and point-of-regard data. With the addition of Polhemus’ FASTRAK®, the world’s leading electromagnetic tracking system, eye motion can be tracked in conjunction with head movement for a complete head tracking solution.
VisionTrak automatically tracks point-of-regard, the correlation of the raw eye position to the precise position on the scene, in real time. The image being viewed by the subject is identified by crosshairs and instantaneously superimposed over live imagery.
Sophisticated, built-in analysis software allows data to be viewed in tabular or graphical format. It also computes velocities and accelerations, or analyzes with user-defined elements. VisionTrak extracts and records the subject’s eye image and raw eye movements, while controlling data collection.
The user-friendly graphical user interface (GUI) built into VisionTrak collects data on the pupil and corneal reflection positions such as: pupil diameters, eye point-of-regard, and a variety of auxiliary parameters. Once collected, data can easily be reviewed, printed, exported, or stored directly on the system.
