Abstract
Touch screens are currently the dominant technology for facilitating input and output for mobile devices. Several directions to extend the possibilities of current touch screen technologies have been explored. In this demonstration we showcase a handheld device that consists of a stack of three see-through displays. Using three display layers enables to realize a volumetric 3D display. As our device is touch sensitive on both display sides it enables touch input on the device's front and back. We demonstrate the device's capabilities through three demo applications. We present 3D images using three display layers, demonstrate a game where the character can move from layer to layer, and show a target selection task to compare selection performance on different display layers.
