Human-Computer Interaction

We have developed a dynamic coarse integral holography approach using opto-mechanical scanning, coarse integral optics and a low space-bandwidth-product high-bandwidth spatial light modulator to display dynamic holograms with a large space-bandwidth-product at video rates, combined with an efficient rendering algorithm to reduce the information content.

We have prototyped a compact, fluid-suspension, electromagnetically-rotated animatronic eye.

We present freeform interactive speakers for creating spatial sound experiences from a variety of surfaces. Traditional surround sound systems are widely used and consist of multiple electromagnetic speakers that create point sound sources within a space.

We present freeform interactive loudspeakers for creating spatial sound experiences from a variety of surfaces.

We present Lumitrack, a novel motion tracking technology that uses projected structured patterns and linear optical sensors.

We describe the conceptual design, architecture, and implementation of a multimodal, robot-child dialogue system in a fast-paced, speech-controlled collaborative game.

We present initial findings from an experiment in which participants played Mafia, an established role-playing game, with our robot.

We present a retrospective view on our experience with small groups of more than 175 children (ages 4 to 10) playing versions of a language-based game hosted by an animated character.

We propose technology for designing and manufacturing interactive 3D printed speakers. With the proposed technology, sound reproduction can easily be integrated into various objects at the design stage and little assembly is required. The speaker can take the shape of anything from an abstract spiral to a rubber duck, opening new opportunities in product design.

An approach of rapid hologram generation for the realistic 3D image reconstruction based on the angular tiling concept is proposed, using a new graphic rendering approach integrated with a previously developed layer-based method for hologram calculation.
