Polhemus VisionTrak

The Polhemus eye tracking system, enables a subject to have full head and eye range of motion while it simultaneously collects eye movement and point-of-eye regard data. With the addition of Polhemus' FASTRAK, the leading electromagnetic tracking system, eye motion can be tracked in conjunction with head movement for a complete head tracking solution. VisionTrak's sophisticated, built-in analysis software allows data to be viewed in tabular or graphical format. It also computes velocities and accelerations, or analyses 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 the system 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.
