We have designed a personal cubic display that offers novel interaction techniques for static and dynamic 3D content. We arrange five small LCD panels into a box shape that is light and compact enough to be handheld. The display uses head-coupled perspective rendering and a real-time physics simulation engine to establish an interaction metaphor of having real objects inside a physical box that a user can hold and manipulate. We have demonstrated four types of interaction techniques with pCubee: viewing a static scene, navigating through a large landscape, playing with colliding objects inside a box, and stylus-based manipulation of objects.
