IBM::The Everywhere Displays Project

The Everywhere Displays project aims to develop systems that allow the transformation of every surface in a space into a projected "touch screen". We are developing a prototype where we combine a LCD projector, a pan/tilt mirror, and a camera. The mirror is used to deflect the image of the projector to surfaces, walls, or the floor of a room. We process the projected image to compensate for the perspective distortion. We employ a pan/tilt video camera to detect hand/body activity on the projected area, so people can interact with the projected image by simply touching the surface.
				No goggles, no wired surfaces
				A major emphasis in this project is to avoid "wiring" surfaces with monitors or other sensing devices. Unlike traditional augmented reality applications, users do not neet to wear graphics goggles or special input devices. Everything happens simply by projection and vision processing: light in, light out. Also, the Everywhere Displays projector can be easily steered to a new surface by a simple software command, thus avoiding fixed setups where projectors or cameras can only perform one specific task. The pan/tilt mechanisms provide dynamic adaptation to changes in the space usage and to different patterns of people activity.
ED-projector in a Store
Three prototypes of application scenarios have been developed so far.The first examines the use of ED-projectors in a retail space. Steerable projected interactive displays are particularly suited to public spaces such as stores since they can be installed on the ceiling, preventing accidental damage and discouraging vandalism and theft.Three different applications have been developed for the retail environment including: interactive bins for women's pants (photo), projected product directories, and an augmented table of Halloween products.
ED-projector in BlueSpace
The second is a prototype of a context-aware, sensor-loaded future office environment called BlueSpace. In this space, the ED-projector is used to deliver silent notifications, to dynamically create collaborative displays on tables and walls, and to contribute to personalization.
				ED-projector at SIGGRAPH'01
				The third prototype is an augmented reality (AR) demonstration scenario of an assembly task. Unlike traditional AR, the use of ED-projectors enable user visualization of information without encumbering goggles and interaction without contact with input devices. In our demo at SIGGRAPH'01, assembly instructions are superimposed on the objects to be assembled. Each individual user contributes to the assembly of an object by executing specific parts of the assembly process, without knowledge of the complete structure of the assembled object.
