Eye mark pointer in immersive projection display

We developed a pointer in 3D virtual space, using an eye-tracking system as a sensor. The eye mark pointer is installed to a virtual environment system which provides stereoscopic vision with an immersive projection display. The circular-polarization stereoscopic vision enables us to use the eye-tracking system in the immersive projection display. The eye-tracking system obtains relative gaze directions with respect to the head, so the absolute position requires compensation of the user´s head motion with a head tracker. We then compare the eye mark pointer with a joystick in an experiment with the virtual environment system. The experimental result indicates the pointing of the eye mark pointer is 9.8 times quicker than that of the joystick, and suggests that the eye mark pointer is available for pointing at the target in the virtual environment
