Title Unobtrusive augmentation of physical environments: Seamless empowerments of the senses
Abstract Augmented Reality (AR) is the concept of merging virtual information with a real environment. It presents an intuitive and direct user interface to annotate real-world objects without physically altering them, with potential use in many different application areas, including medicine, maintenance and repair, architecture, and entertainment. Most traditional AR systems have however required encumbering equipment, such as head-worn displays, active or passive stereo glasses, and position and orientation trackers, to produce the registered augmentation effect. Their complexity and indirectness, however, limit their applicability in many scenarios.

Recent advances in a number of technological areas have inspired our research in AR interfaces that support sporadic and spontaneous interaction with a seamless blend of the digital and physical. This new concept, which we call Unobtrusive AR, emphasizes an optically direct view of a visually unaltered physical environment, the avoidance of user-worn equipment, and the preference for unencumbering techniques.

We contribute a set of novel interaction techniques, display systems, and sensing technologies, which include research in touch-screen interaction, spatially aware mobile devices, direct projection systems, holographic technology and immaterial displays.

Alex Olwal is a Ph.D. Candidate in the School of Computer Science and Communication at KTH (The Royal Institute of Technology) in Stockholm, where he received his M.Sc. in Computer Science and Engineering in 2002. In 2002 and 2003 he was a visiting scholar and staff associate researcher in the Dept of Computer Science at Columbia University in New York. During 2005 he was a visiting researcher in the Dept of Computer Science at University of California, Santa Barbara.

Alex's research focuses on interaction techniques and technology for handheld and spatial Augmented and Mixed Reality systems. His research interests include spatially aware mobile devices, ubiquitous computing, touch screen interaction, as well as novel interaction devices and displays.
