We developed an eye movement analysis system using eye images during many kinds of eye movements. The system can display any kind of pattern in front of their eyes. It can analysis eye movements while subjects are on some ocular tasks. Our experimental system consists of a head mount display with a color liquid crystal display, infrared LEDs, and an infrared sensitive CCD camera. The camera is attached to the display goggle. The goggle is very light and it is a non-invasive system. In this study, we conducted the examination of eye tracking function. We made an moving target on the small liquid crystal display. The system could provide detailed data of the relationship between the eyes and the target position. It could be very useful for clinical diagnosis of neurological diseases.
