A visual extension device that can be used without hands is extremely useful. By using the BES (Bioelectrical Signal), user’s operational intentions can be detected without obstructing the user’s field of view. Moreover, the sensors are small and thin and contribute to downsizing systems.
We proposed and developed a novel visual extension system with intuitive interface triggered by BES. The developed system consists of a camera unit, a HMD, a control unit, and a Personal Computer (PC). The electrodes are attached to the user’s temple, and measure BES. The control unit processes the BES and operates the zoom and focusing functions of the camera unit. The image acquired by the camera unit is sent to the HMD.
The developed system is easy to wear and use for any users, and performs a calibration of BES for about ten seconds. When the user chews and squints, the camera zooms in. When the user blinks largely the camera zooms out. User is able to obtain sharp enlarged image by the optical zoom lens.
