This paper introduces the Everywhere Displays projector, a device that uses a rotating mirror to steer the light from an LCD/DLP projector onto different surfaces of an environment. Issues of brightness, oblique projection distortion, focus, obstruction, and display resolution are examined. Solutions to some of these problems are described, together with a plan to use a video camera to allow device-free interaction with the projected images. The ED-projector is a practical way to create ubiquitous graphical interfaces to access computational power and networked data. In particular, it is envisioned as an alternative to the carrying of laptops and to the installation of displays in furniture, objects, and walls. In addition, the use of ED-projectors to augment reality without the use of goggles is examined and illustrated with examples.
