A transparent display with per-pixel color and opacity control

We propose a new display system that composites matted foreground animated graphics and video, with per-pixel controllable emitted color and transparency, over real-world dynamic objects seen through a transparent display. Multiple users can participate simultaneously without any glasses, trackers, or additional devices. The current prototype is deployed as a desktop-monitor-sized transparent display box assembled from commodity hardware components with the addition of a high-frame-rate controllable diffuser.
