Augmentation of a fuse box. At left, a projected room map. The user tracks the cursor to a location on the map and clicks to invoke a projected highlighting of the corresponding fuse. The outer black rectangle defines the coordinate frame for the projec- tion. The colored circular badges are used to determine appropriate projected content for this object.

Handheld projectors offer a new type of display modality, not tied to a physical screen or to a fixed projection area, yet providing a larger display than is available from a handheld device with fixed screen. This paper begins with a review of our prototype handheld projector, and describes our work on interaction using a cursor that can be tracked across the projection. The most immediate use for such a device is to support existing applications like web-browsing. We show examples of this type of application.
But there is a broader question too - does a handheld projector support new types of application that are not available with a phys- ical screen or a fixed projection? We describe two applications that illustrate how the combination of handheld projection plus interac- tion supports ways to interact with the physical world that are much more natural than via conventional displays.
