Classification of EOG for Human Computer Interface
This paper uses Electro-ocular gram (EOG) to track the angular gaze of the eyes in order to determine a mathematical expression that is user independent.
Electrodes were placed on the subject’s face to gather signals. A test environment was set-up that gave the subjects “targets” to look at.
These targets were placed around the subject, in a sphere shape (see figure below). The subject was then directed to look at specified targets and the data was compiled.
After some filtering and linear regression magic, a model with high probability was constructed.
The findings show that the greater the angle, the less accurate the system. Peripheral vision was not well accounted for using this method.
Also, this method did not account for torso and other “non-eye” movement. Disabilities and “lazy-eye” were also not accounted for.
