Abstract: A goggle based light-weight VOG system includes at least one digital camera connected to and powered by a laptop computer through a firewire connection and allows for region of interest image processing. The VOG system is a modular design whereby the same goggle frame or base is used to build a variety of digital camera VOG systems. The VOG system may track and record head position and goggle slippage. An animated eye display may provide data in a more meaningful fashion. An EOG system may be incorporated directly into a goggle base. The digital camera may digitally center the pupil in both the X and Y directions. A calibration mechanism may be incorporated onto the goggle base. The VOG system may be a modular design whereby the same goggle frame or base is used to build a variety of digital camera VOG systems.

Abstract: A goggle based light-weight VOG system includes at least one digital camera connected to and powered by a laptop computer through a firewire connection together with an integral visual light stimulus source. The digital camera may digitally center the pupil in both the X and Y directions. A calibration mechanism may be incorporated onto the goggle base. An EOG system may also be incorporated directly into the goggle. The VOG system may track and record 3-D movement of the eye, track pupil dilation, head position and goggle slippage. An animated eye display provides data in a more meaningful fashion. The VOG system is a modular design whereby the same goggle frame or base is used to build a variety of digital camera VOG systems.
