We investigated the effect of frame delay on stereoscopic vision by using a moving object in a virtual environment. The object was translated along the x-, y-, or z-axis or was rotated around the x-, y-, or z-axis while changing its speed and size. The effect on stereoscopic vision was measured by using the method of limits by changing the delay (i. e., the number of frames) between left-eye image and right-eye image. The measurements clarify the change tendencies with a maximum number of delays and allow the viewer to enjoy clear stereoscopic images when frame delay occurs.
