    This article reviews the motivations, approaches, and accomplishments in applying genus loci - the sense of place - to advance Google's mission to organize the world's information and make it universally accessible and useful. Delivering information in a meaningful spatial context has proven an ambitious undertaking. Ideas from philosophy, psychology, and sociology shaped the design, and technical... View full abstract»

    This article describes a prototype immersive musical instrument that expands the concepts of traditional musical elements and allows the integration of a spatial dimension using 3D music and sound objects into the musical environment by employing physical, visual, and sound immersion. From the prototype's evaluation results, we conclude that immersive musical instruments naturally give users a way... View full abstract»

    Digital libraries (DLs) in general and technical or cultural preservation applications in particular offer a rich set of multimedia objects like audio, music, images, videos, and also 3D models. However, instead of handling these objects consistently as regular documents - in the same way we treat textual documents - most applications handle them differently. Considering that textual documents are... View full abstract»

    Methods for automatically extracting descriptors from 3D objects are key to searching and indexing techniques in their growing repositories. The authors present two recently proposed approaches and discuss methods for benchmarking the 3D retrieval systems' qualitative performance. View full abstract»

    Due to increasing product design complexities and the ever-expanding variety of product parts, the amount of information that designers must catalog has exploded. Accordingly, capable CAD tools to help designers create engineering artifacts are now pervasive. The volume of such engineering artifacts generated has increased exponentially and enterprises spend huge resources to organize and archive ... View full abstract»

    Mobile augmented reality requires georeferenced data to present world-registered overlays. To cover a wide area and all artifacts and activities, a database containing this information must be created, stored, maintained, delivered, and finally used by the client application. We present a data model and a family of techniques to address these needs. View full abstract»

    Safety is one of the main concerns in maritime activity. Although the safety of a ship may be determined by many uncontrollable factors (such as weather or human error), efficient and continuous monitoring of shipboard systems and the current safety status is crucial to avoid or at least minimize the effects. Most modern ships have a Damage Control Center onboard where the crew monitors ship syste... View full abstract»

  • Representing Interwoven Surfaces in 2-1/2D Drawings

    Drawing programs must be able to distinguish which surface is on top anywhere that two surfaces overlap. Existing drawing programs do this by assigning surfaces to distinct layers, so they can't represent interwoven sets of surfaces. Druid uses a more general representation by maintaining local depth ordering of segments of a drawing's surface boundaries rather than a global depth relation between... View full abstract»

    An essential goal of OpenGL is to provide device independence while still allowing complete access to hardware functionality. The API therefore provides access to graphics operations at the lowest possible level that still provides device independence. In OpenGL, the maximum flexibility provided by individual procedure calls was deemed more important than any inefficiency induced by using those ca... View full abstract»

    People who experience an immersive VR system usually report feeling as if they were really in the displayed virtual situation, and can often be observed behaving in accordance with that feeling, even though they know that they're not actually there. Researchers refer to this feeling as "presence" in virtual environments, yet the term has come to have many uses and meanings, all of which evolved fr... View full abstract»
