One of the major limitations of portable computing devices is the small size of their built-in displays. Fortunately, extremely small projection systems are being developed that can be integrated into devices that are small enough to be body-worn, yet can project a large image onto surfaces in the environment. To explore how a user might interact with this near-horizon technology, we created a functional simulation of a wrist-worn projector. We then developed a set of interaction techniques that assume that the wrist-worn computer and projector are equipped with position and orientation sensors, in addition to a touch-sensitive builtin screen. To complement the techniques that rely on the spatial manipulation of the user's forearm and the device itself, we also describe the use of a cursorless watch user interface that minimizes the need for the user to look down at the device's built-in screen. Finally, we present a sample application that illustrates our interaction techniques.
We present a novel approach for using pictorial artwork as information displays and show how to combine almost any kind of computergenerated visual information directly with the painted content.

MotivationPictorial artwork, such as paintings and sketches, can tell interesting stories. The capabilities of museums to communicate such and other information, however, are clearly limited. Text legends and audio guides can mediate facts, but offer little potential for presenting visual content, such as embedded illustrations, pictures, animations, and interactive elements.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
