EOG-based system for mouse control

The fact that the oculomotor system is one of the last capabilities that people suffering from neurodegenerative diseases or trauma retain allows us to develop a system to provide a means of communication for this particular target group. The retinal resting potential causes an electric field around the eyeball, centred on the optical axis, which can be measured by placing electrodes near to the eye. An acquisition system and a LabVIEW application were implemented for measuring these biopotentials in order to detect the movement of the eyes and to provide a relative gaze position, making it possible to control the computer mouse. Several techniques are implemented to denoise the EOG signal obtained in noisy environments for use in biomedical diagnosis.
