Biopotential eye tracking detects the eye position or gaze direction using electro-oculographic bioelectrical signals called EOG from the human skin near eyes. The objective is to design and implement an inexpensive human machine interface using these EOG signals. The project involves research, design and implementation of the interface along with software and hardware based applications. This work integrates biological signal acquisition, analog circuit design, digital signal processing, software programming, and bio-electrical engineering; to form a product with a wide range of applications...
