We present an approach to 3D printing custom optical elements for interactive devices
labelled Printed Optics. Printed Optics enable sensing, display, and illumination elements to …

Instrumented with multiple depth cameras and projectors, LightSpace is a small room
installation designed to explore a variety of interactions and computational strategies related …

Spatial augmented reality (SAR), which typically uses projectors to augment physical spaces
with virtual contents, is one of the three main forms of augmented reality. In SAR systems …

Entertainment and in particular gaming is currently considered one of the main application
scenarios for virtual reality (VR). The majority of current games rely on any form of …

LightGuide is a system that explores a new approach to gesture guidance where we project
guidance hints directly on a user's body. These projected hints guide the user in completing …

Projectors are pervasive as infrastructure devices for large displays but are now also
becoming available in small form factors that afford mobile personal use. This article surveys …

We present Bonfire, a self-contained mobile computing system that uses two laptop-
mounted laser micro-projectors to project an interactive display space to either side of a …

Recent technological advances in input sensing, as well as ultra-small projectors, have
opened up new opportunities for interaction--the use of the body itself as both an input and …

Steerable displays use a motorized platform to orient a projector to display graphics at any
point in the room. Often a camera is included to recognize markers and other objects, as well …
