Biomedical instrumentation based on electrooculogram (EOG) signal processing and application to a hospital alarm system

The electrooculogram (EOG) signal is acquired by a bi-channel signal acquisition system and prominent artifacts and interference are suppressed. It is then processed for use in biomedical instrumentation systems such as eyeball tracking and blink detection. This paper also discusses the application of EOG signal processing to the control of a dual stage hospital alarm system. EOG based bio-control is found to be a suitable alternative to current control schemes, especially for quadriplegics and severely paralyzed patients.
