The hardware component of the technology used to communicate with people with major neuro-locomotor disability using ocular electromyogram

In this paper, the hardware component of a new technology used to communicate with people with major neuro-locomotor disability using ocular electromyogram is presented. The signals produced by the ocular muscle, provided by five electromyogram sensors are amplified used a new instrumentation amplifier and then processed by the software component of the proposed communication technology. The information obtained after these signals are processed is used in order to move a pointer on a display in concordance to the patient gaze direction. In this way, the needs of the patient are sent to the caretaker by detection of voluntary blinking.
