We introduce a new type of interactive surface technology based on a switchable projection screen which can be made diffuse or clear under electronic control. The screen can be continuously switched between these two states so quickly that the change is imperceptible to the human eye. It is then possible to rear-project what is perceived as a stable image(More)
In this paper we present novel input devices that combine the standard capabilities of a computer mouse with multi-touch sensing. Our goal is to enrich traditional pointer-based desktop interactions with touch and gestures. To chart the design space, we present five different multi-touch mouse implementations. Each explores a different touch sensing(More)
The planar manipulator display uses physical objects for human-computer interaction. This system addresses the poor match between standard computer interfaces and human spatial awareness. The desire to take advantage of these abilities was our primary motivation in developing the planar manipulator display (PMD). The PMD uses movable physical objects as a(More)
Adding multi-touch sensing to the surface of a mouse has the potential to substantially increase the number of interactions available to the user. However, harnessing this increased bandwidth is challenging, since the user must perform multi-touch interactions while holding the device and using it as a regular mouse. In this paper we describe the design(More)
Physical design environments are places that support people engaged in the spatial, physical, tangible act of creation. It is now possible to augment workspaces with an amazing array of technologies to assist users in their creative endeavors. However, the integration of computing technologies into physical environments involves a new set of tools,(More)
