Text input method and apparatus using bio-signals

Abstract

A method and apparatus for inputting text, by dividing the letter arrangement on a keyboard by area, providing the divided letter arrangement areas on the screen, and making letters be selected step by step according to the bio-signal of a user, are provided. The text input apparatus using a bio-signal includes: a sensor detecting a bio-signal of a human being; a bio-signal measuring unit analyzing the detected bio-signal and extracting characteristic information; and an instruction generation unit converting the characteristic information into an instruction used to drive an application program, according to a preset mapping relation prepared corresponding to the extracted characteristic information. According to the method and apparatus, communications by users, who cannot practically use conventional interfaces, such as a mouse and a keyboard and therefore, experience difficulties in communicating with others in a computing environment, can be easily performed.
