Abstract
An interactive three-dimensional display system includes a three-dimensional display panel which has an optical sensor array, an interactive device which includes a projection light source and a shadow mask, and an image recognizing unit. The shadow mask has a pattern to define an image projected by the interactive device. The image is captured by the optical sensor array. The pattern includes two strip patterns which cross each other. The image includes two strip images which cross each other. The image recognizing unit is electrically connected with the optical sensor array and calculates relative positions of the interactive device and the three-dimensional display panel according to the image. A method of calculating the relative positions includes calculating according to the lengths of one of the strip patterns and one of the strip images, and a divergent angle and tilt angle of the projection light source.
