|Title||Eye Controlled Typing Using PIC16F877A|
People with physical disabilities face a lot of problems in communication with their fellow human beings. In this paper, the design of an eye-controlled system with an emphasis on the Human-Computer-Interface (HCI) based on Electroencephalography (EEG) has been presented. The basis for this design is the electric potentials generated by the human eye. After this potential is sensed by electrodes, the signals are amplified, filtered, shifted, and sent into the PIC microcontroller. Also, additional processes were designed to overcome the sources of EEG signals variation. The signals captured using sensors, are first amplified, and then noise is removed and then digitized, before being transferred to PC for software interfacing Using PIC16F877A and RS232 serial communication. Visual basic software is used to build a nonconventional keyboard layout.
