3-D display using motion parallax for outdoor user interface

This paper describes a 3-D display that can express differences between depths at extended distances of over a hundred meters for moving observers using motion parallax. The results of a subjective test demonstrated that the perceived depth of the image at long distances could be controlled using artificial motion parallax generated by changing the rate of expansion of the image size, irrespective of its real depth. As a result, we demonstrated its possibility for applications to car-navigation systems combined with augmented-reality technology.
