Iranian researchers at a science center in Isfahan Province, central Iran, have designed a headband which helps people who have lost their power of speech and motion to communicate with others through computer and typing.
Samaneh Behtash, the lead author of the study, said that the system processes electronic signals of the eye. When the individual is in front of the keyboard and wears the headband, the system starts processing electronic signals of the eye.
As the individual looks at the intended letter, the eye’s signals are processed and changed to computer commands. Then the intended letters and words are typed.
According to the researcher, the device does not need cable connections and can start typing wireless.
The signals received by the headband are sent to the computer via Bluetooth and the computer starts typing after processing the received signals.
