Tangible Magic Lenses – Graspable Displays for Exploring Information
Until now, information exploration techniques are often restricted to traditional input and output devices, which are typically limited to one (larger) screen operated by mouse and keyboard interaction. In recent years, researchers started to also investigate several other interaction modalities. Thereby, they often employ interactive surfaces which are operated by multitouch, gesture, pen or other means of tangible interaction. In most cases interaction is limited to the surface itself, as with gestural interaction or tangibles on a tabletop. Moreover, the surfaces are mostly fixed in space (wall displays, tabletops, desktop displays) or in the user’s hands (smart phones, tablets) and therefore do not utilize their location.The talk will focus on the display aspect of tangibles as well as the tangible aspect of displays. Tangible magic lenses will be introduced as one solution to seamlessly interact in mixed realities. These are optically tracked, lightweight, passive displays that provide elegant three-dimensional exploration of rich datasets. This can either be volumetric, layered, zoomable, or temporal information spaces, which are mapped onto the physical volume above a tabletop. By moving one or multiple hand-held magic lenses through the volume, corresponding data is displayed, thus serving as a window into virtuality. Various interaction techniques are explained, which especially utilize the lens’ position and orientation in a novel way and provide a rich vocabulary of physical gestures on the lenses as well as with the lenses. The talk will demonstrate various promising application examples which we developed at the User Interface & Software Engineering group of the University of Magdeburg and will also outline future challenges for graspable displays.
