Creating Ubiquitous Interactive Games Using Everywhere Displays Projectors

This paper introduces the Everywhere Displays projector, a device that uses a rotating mirror to steer the light from an LCD projector onto different surfaces of an environment and a pan/tilt camera to sense interaction with the projected surface. The ED-projector is a generic I/O ubiquitous device that is able to create graphical interfaces on non-wired surfaces, to access computational power and networked data. Also, ED-projectors can be used to augment reality without the use of goggles. In both cases, ED-projectors can be used to create a new generation of games that are played by one or more users on the real world, without requiring them to wear goggles neither asking for specially wired surfaces or objects. Some ideas of the games that can be created with the ED-projector are introduced and examined

SearchLight - A Lightweight Search Function for Pervasive Environments

We present a lightweight search function for physical objects in instrumented environments. Objects are tagged with optical markers which are scanned by a steerable camera and projector unit on the ceiling. The same projector can then highlight the objects when given the corresponding marker ID. The process is very robust regarding calibration, and no 3D model of the environment is needed. We discuss the scenario of finding books in a library or office environment and several extensions currently under development. The SUPIE environment The Saarland University Pervasive Instrumented Environment (SUPIE) is an instrumented room with various types of displays, sensors, cameras, and other devices. By means of a steerable projector, the room has continuous display capabilities which are limited in resolution and temporal availability (only one area at a time). The various other displays provide islands of higher resolution and interactivity within this display continuum. The projector can project arbitrary ligh
