Laser Sensing Display

In this line of research, we are creating interactive laser display systems that are capable of sensing interaction without the use of external cameras. These display systems use modulated galvo-scanning lasers to project laser light and then detect it with a fast photodetector. This enables highly responsive (up to 1000 Hz) detection of interaction with the projector graphics. Some potential uses for this work are implementing interactive spatial Augmented Reality interfaces and displays that present dynamic information on real-world surfaces and overlapping real and virtual environments to create seamless interfaces and displays where the use of existing headsets is not practical.
