Abstract

Handheld projection lets users create opportunistic displays on any suitable nearby surface. This projection method is a practical and useful addition to mobile computing. Incorporating a projector into a handheld device raises the issue of how to interact with a projection. The focus of the article is interactive projection: a technique for moving a cursor across a projection, allowing all the familiar mouse interactions from the desktop to be transposed to a handheld projector, and requiring only natural, one-handed pointing motion by the user. This article is available with a short video documentary on CD-ROM.
