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)
Peripheral administration of motilin has been found to stimulate feeding behavior in rats. Since motilin immunoreactivity has been found in discrete brain sites, we tested the effect of motilin administered intracerebroventricularly on feeding in rats. Injection of 1 microgram of motilin significantly increased food consumption at 2 hours, 22 hours, and at(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)
COntext and evidenCe The sustainability of our cities—as measured by both the quality of life they provide today, and the long-term environmental protection they promise to future generations—will determine the future of our planet. Considering the host of social and environmental challenges we currently face—including global warming, air quality concerns,(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)
