Abstract— This paper proposes a novel binocular‐disparity three‐dimensional (3‐D) display with accommodative compensation (3DDAC) to achieve fatigue‐free viewing. The display principle is based both on detecting gaze points and moving the display screen to the gaze depth in real time. Gaze detection is discussed with respect to whether eyeball rotation occurs or not, and screen motion is discussed with respect to whether the screen is real or a virtual image. In an experimental setup, a 3‐D computer‐graphics image was produced to evaluate the accommodation effect. The gaze position was fixed at the center of the field of view, and the display depth was controlled by a z ‐buffer value of the pixel focused on. The display screen was then moved, as a virtual image, by back‐and‐forth movements of a relay lens. It was determined that the perceived sharpness of the image increased for the proposed display mode.
