Design of human-computer interaction helmet for wearable computer

A kind of human-computer interaction helmet for wearable computer is designed after the analysis of working principle of eye tracking and voice interaction. The helmet is composed of helmet mounted display and its adjusting device, box, eye tracking device, backboard, helmet support, earphone, microphone, etc. Each element´s position relation and system function are described in detail. Combined with the characters of the helmet, the calibration principle of the eye tracking system is anatomized and the calibration flow is ascertained. The human-computer interaction is realized based on eye tracking and voice channel. The helmet with great flexibility and advantage enhances the interaction reliability and extends the application fields of the wearable computer.
