PORTABLE VIDEO OCULOGRAPHY WITH REGION OF INTEREST IMAGE PROCESSING
First Claim
1. A portable video oculography system comprising:
- a head mounted base adapted to be attached to a patient'"'"'s head;
at least one digital camera attached to the base, each camera 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 crop the images to a defined region of interest of each image, whereby the controller is configured to ignore the data outside of the region of interest of the digital image following the cropping.

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. 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.
