AbstractThe authors studied depth positions of the title characters corresponding to the best viewing of the entire screen, while stereo pictures and title characters were presented at the same time on a stereo display by liquid‐crystal shutter eyeglasses. They conducted subjective tests of dynamic images obtained by rotation for measuring the best viewable title character positions with varying conditions of picture depth positions and rotation speed, as well as with different picture representation models. Positions expressing the average depth rate of the presentation pictures were defined as mean depth positions, and the results were compared with the test results. It was discovered that the title character positions corresponding to the best viewable screen closely matched the mean depth positions when the solid model was used for expressing the presentation pictures. Moreover, when pictures were expressed by the wire‐frame model, the best view positions of the title characters closely matched the mean depth positions for the case when the same pictures were represented by the solid model. In addition, the best viewable title character positions were the same at rotation speeds of 20 and 80°/s, which demonstrated that they were not affected by the rotation speed. © 2002 Wiley Periodicals, Inc.
