David Krum Presents at Ubiprojection at Pervasive 2010

May 17, 2010 | Helsinki, Finland

Speaker: David Krum, ICT
Host: Eighth International Conference on Pervasive Computing

David Krum will present his paper accepted to the Ubiprojection workshop which is part of the Pervasive 2010 conference (Eighth International Conference on Pervasive Computing). The title of Krum’s presentation is “Augmented Reality Applications and User Interfaces Using Head-Coupled Near-Axis Personal Projectors with Novel Retroreflective Props and Surfaces,” and his paper is a result from the ICT Seedling supporting the head mounted projector project.

One motivation for the development of augmented reality technology has been the support of more realistic and flexible training simulations. Computer-generated characters and environments – combined with real world elements such as furniture and props to ‘set the stage’ – create the emotional, cognitive, and physical challenges necessary for well-rounded team-based training. This paper presents REFLCT, a mixed reality staging and display system that couples an unusual near-axis personal projector design with novel retroreflective props and surfaces. The system enables viewer-specific imagery to be composited directly into and onto a surrounding environment, without optics positioned in front of the user’s eyes or face. Characterized as a stealth projector, it unobtrusively offers bright images with low power consumption. In addition to training applications, the approach appears to be well-matched with emerging user interface and application domains, such as asymmetric collaborative workspaces and mobile personalized guides.
