Portable high speed head mounted pupil dilation tracking system
First Claim
1. A portable, high speed, head mounted pupil dilation tracking system comprising:
- a head mounted base adapted to be attached to a patient'"'"'s head;
at least one digital camera attached to the base, operating at least at 30 frames per second and configured to take images of one of the patient'"'"'s eyes; and
a controller coupled to each digital camera and receiving and storing data signals there from, the controller configured to calculate eye related data including pupil dilation from the digital camera images, and configured to display the eye related data to users.

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 high speed pupil dilation tracking. 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 track and record head position and goggle slippage. An animated eye display may provide data in a more meaningful fashion. 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.
