SENSOR DE PISCADAS PARA COMUNICAÇÃO ENTRE PACIENTE E CUIDADOR.

This paper aims to verify the possibility of eye blinking interpretation to create a means of communication between patient and caregiver. A control device was designed and developed using an infrared sensor and an infrared LED pointed towards the patient's eye installed in an eyeglass frame. The interpretation information is made by Arduino nano similar device and information is presented on an LCD display. When there is a blink the device changes the information displayed on the display, facilitating the exchange of basic informations between patient and caregiver. As the infrared LED is a heat emitter, it was observed that the power emitted by the system is at safe levels being much lower than the maximum values stipulated in the standards. The tests showed that the development of the device using infrared for blink interpretation is possible.
