ABSTRACTThe vision of pervasive ambient information displays which show relevant information has not yet come true. One of the main reasons is the limited number of available displays in the environment which is a fundamental requirement of the original vision. We introduce the concept of an Ambient Mobile Pervasive Display (AMP-D) which is a wearable projector system that constantly projects an ambient information display in front of the user. The floor display provides serendipitous access to public and personal information. The display is combined with a projected display on the user's hand, forming a continuous interaction space that is controlled by hand gestures. The paper introduces this novel device concept, discusses its interaction design, and explores its advantages through various implemented application examples. Furthermore, we present the AMP-D prototype which illustrates the involved challenges concerning hardware, sensing, and visualization.

Traces

“…Rogers et al [37] found the visualisation, in part because it was embedded in the road, engaged residents more than a wall display. Floor displays, either as static fixed stickers or as non-interactive projections, are often employed as advertisements, or to show efficient navigational routes through complex buildings [39,47].…”

Map Navigation Using a Wearable Mid-air Display

“…Ota et al [15] explored 16 body locations for wearing multiple projectors for navigation and a photo-slide show while walking and standing, displaying information on floors. The Ambient Mobile Pervasive Display is a shoulder-mounted projector able to display on surfaces around the environment, the floor, and the hand [23]. Cauchard et al [3] identify challenges of handheld pico-projectors used on walls, desks, and floors, suggesting that this setting is unsuitable for many tasks.…”

Confined projection on selected sub-surface using a robust binary-coded pattern for pico-projectors

“…Applications of projector phones for picture browsing and map interaction has been explored in [13,17]. Improving upon the work of Omni Touch [18] and Beamatron [19], Winkler et al [20] proposed a wearable projector system that constantly projects an ambient information display in front of the user. By utilizing a Kinect-based depth sensor they were able to detect the projection surface as either a floor or the user body.…”
