I had a new head mounted infrared eye tracker for testing purposes
in my lab and was quite pleased with its features.
In its basic version it is a standard eye tracker with a resolution of
0.1 deg and 1 ms. The adjustment and calibration is surprisingly easy.
Background light tolerated.
Optional the system is equipped with 3 head mounted laser light sources
to provide a fixation point and two possible visual stimuli with user
selected timing. In this form the system comes as a stand-alone
transportable apparatus to be used in clinical and psychological
application to test a subject's efficiency of generating reflexive and
voluntary saccades. It measures automatically reaction time and
direction error rate with the help of a hand held processor (PC optional
but not needed). The head mounting largely compensates variations in
head position and viewing distance.
