Innovative Assistive Communication Device Developed by Undergraduate Final Year Project Students

The students of IIT Palakkad have developed an innovative, low-cost assistive communication device to aid paralyzed and speech-impaired patients. The device uses electrooculography (EOG) to capture the eye movements of the patient to enable them to use a customized virtual keyboard and type on the monitor. For patients affected by weak muscular movement of the eye, the device captures even a residual, minuscule voluntary motion of a finger and translates the signal for typing using the virtual keyboard without touching the keys. The device is developed by the final-year BTech Electrical Engineering students, Vishal Choudhari and Anjali Agarwal, under the guidance of Prof. Vinod A. Prasad, Dean – Industry Collaboration & Sponsored Research, IIT Palakkad.
