Abstract
The present study proposes an assistive device for the bed-ridden persons. The ocular activity of the bed-ridden patients is not lost even during the condition of limited or no motor activities. The proposed device acquires biosignals associated with the eye blinks and activates an alarm or communication protocol. The device is capable of communicating via SMS, e-mail and voice calls to a landline/mobile number once activated. The device can enable the patients to interact with the healthcare-givers whenever they are in need. Hence, the device is supposed to reduce the workload on the healthcare-giver.
