Abstract

We have built a HOE-based display capable of reconstructing arbitrary images, in mid-air at fixed focal depths, that can interact with the viewer in real-time. The display system comprises the HOE, a laser projection subsystem, a Kinect motion sensor and an embedded controller. The HOE functions as a fast converging lens and is A4 page sized (20×30cm). We have written a number of simple apps for the display that allow the user to draw in mid-air or to touch icons and buttons that trigger other actions. The reconstructed holographic images are high-resolution, relatively bright and visible under ambient indoor lighting conditions.
