This paper reports on ways of using digitised video from television cameras in user interfaces for computer systems [6]. The DigitaiDesk [11, 12] shown in Figure 1 is built around an ordinary physical desk and can be used as such, but it has extra capabilities. A video camera mounted above the desk, pointing down at the work surface, is used to detect where the user is pointing and to read documents that are placed on the desk. A computer-driven projector is also mounted above the desk, allowing the system to project electronic objects onto the work surface and onto real paper documents. In particular, this technology has been applied to electronic publishing. The goal is to combine electronic and printed documents to give a richer presentation than that afforded by either separate medium. We introduce the idea of combined documents, show how they can be used for mixed-media publication and discuss some of the technical issues involved.
