01 / About

Expanding reality
through visual technology.

The Visual Computing & Augmented Reality Lab. investigates 3D stereoscopic visualization, motion analysis, HCI and information-visualization techniques grounded in computer graphics and image processing.

We also study core technologies for augmented reality, which seamlessly aligns virtual objects and information with the physical world, and develop application systems that bring those technologies into use.
