Eye Tracking Equipment

This ASL Model H6 eyetracker is the centerpiece of our experiments of language acquisition. We have developed a system for recording the image of the observer's eye and overlaying this on the video record containing the location of gaze. This allows better evaluation of small eye movements and allows us to minimize the effects of tracker noise in our data.

Position Sensing Equipment

LIBERTY by Polhemus incorporates a speed of 240 updates per second per sensor, the ability to upgrade eight sensor channels and detection distortion. In our experiments, multiple sensors are attached to subjects to monitor and record their body movements.

Video Recording Equipment

SONY EVI-D70 color video cameras have a wider pan/tilt range with an 18x optical zoom lens and a faster and smoother pan/tilt mechanism plus autofocus and autoexposure. The RS-232C/422 serial connection allows us to control the cameras by computer programs.
