Abstract

In the field of eye tracking, greater accuracy or resolution in monitoring movement of the eye can be gained by digitizing the eye, and tracking the movement of a landmark with fixed size and a fixed location relative to the eye's local coordinate system. The edge of the iris can be used as such a fixed landmark. Through the location and or establishment of at least a portion of the outer edge of the iris and/or an iris center point, both large and small scale eye movements, including but not limited to micro-tremors, can be traced with a higher degree of accuracy. This will aid in the diagnosis of diseases, assessing state of consciousness, and defining brainstem death.

Abstract

A goggle based light-weight VOG/EOG system includes at least one digital camera connected to and powered by a laptop computer through a firewire connection. The EOG system is 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 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.

Abstract

2 and at velocities in excess of 12000 degrees/second. The bandwidth of the XY interface is greater than 400 Hz, providing high image reproducibility. The repeatability and position accuracy of the target is +−3 arc-seconds and the field of range of the XY interface are about 60 degrees (i.e. about 60 degrees horizontal and 60 degrees vertical).

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. 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.
