Multi-view displays reproduce more than one view of an object. Classical 3D displays allow only a single user. Today’s multi-view displays are flat and reproduce two or more images. They base on e.g. parallax barrier, lenticular lenses, light field displays and projection with reduced effective resolution. Another method is projection on rotating mirrors. This approach requires highest frame rates (~5,000 Hz), so only prototypes without color and grey are realized so far. Our approach base on a rotating (prototype 60 rps) periscope-like mirror system (with magnification) in the center of a 360° circular display. For prototyping, we used large high-resolution flat displays. One simple method is to use a fixed position on a single display for every corresponding view. To avoid motion blur and ghosting one mirror is equipped with a vertical slit screen to block light from neighboring areas. We implemented eye tracking for efficient rendering in real time and reproduce only relevant views according the corresponding angular position of the viewer’s eyes. So a standard high resolution display can be used to generate thousands of different perspectives (at full color and 60 Hz). Possible applications of our multi-view display are collaborative work for e.g. several designers, which can see the object from very different locations and interactively improve design, (science) museums and entertainment.
