These virtual worlds are able to train, explore and entertain in addition toaugment the real world with information for our everyday lives. To perform tasks such as traveland other interaction, researchers in these worlds have focused heavily on issues of three-dimensionalinteraction, including interaction techniques, user interface metaphors and inputdevices but always with an outlook centric to their particular position along the MR continuum.This has resulted in interfaces tuned to certain MR instances that are not possible in them allbecause of factors such as the display types, tracking issues or interference and limits from thereal world.This panel brings together diverse researchers across the MR continuum to discuss theirresearch and dissect the similarities and differences of each other's fields. The result is anunderstanding of interfaces across these realities and a merger of developing terminology,techniques and tools for future collaborations.Panel members will give a description of their research followed by a short vision of futureinterface research. Audience questions submitted via index cards are heavily encouraged andexpected to shape the panel discussion and direction.","PeriodicalId":105245,"journal":{"name":"IEEE Virtual Reality, 2003.

This paper presents Virtual-SAP, an immersive VE application allowing users to assess building structures and their response to various environmental conditions through an interactive design-build-test-redesign cycle. Virtual-SAP has three distinct user interfaces that support its use with a high-end, multi-tracker VE system, with a low-cost portable VE system, or on the desktop. Two of these interfaces have been proven highly usable in user testing, and the third will be tested soon. Virtual-SAP is being used for both research and education.","PeriodicalId":105245,"journal":{"name":"IEEE Virtual Reality, 2003.

The database represents information about the layout of streets and sidewalks, the rules that govern behavior on roads and walkways, and the locations of agents with respect to road and sidewalk structures. This information is used by programs that control the behavior of autonomous vehicles and pedestrians populating the virtual urban environment. Roads and sidewalks are modeled as ribbons in space. The ribbon structure provides a natural coordinate frame for defining the local geometry of navigable surfaces. This geometry is important for way finding and also forms the geometric basis on which spatial relationships among agents are defined. The database includes a powerful run-time interface supported by robust and efficient code for locating objects on the ribbon network, for mapping between Cartesian and ribbon coordinates, and for determining behavioral constraints imposed by the environment.","PeriodicalId":105245,"journal":{"name":"IEEE Virtual Reality, 2003.

The tracker uses invariant properties of marker patterns to efficiently identify and reconstruct the pose of these interaction devices. Since invariant properties are sensitive to noise in the 2D marker positions, an offline training session is used to determine deviations in these properties. These deviations are taken into account when searching for the patterns once the tracker is used.","PeriodicalId":105245,"journal":{"name":"IEEE Virtual Reality, 2003.

{"title":"Taking it to the streets: how virtual reality can change mobile computing","authors":"Steven K. Feiner","doi":"10.1109/VR.2003.1191114","DOIUrl":"https://doi.org/10.1109/VR.2003.1191114","url":null,"abstract":"Virtual reality has long been an indoor affair. Whether constrained by stationary computers ordisplays, or by the limitations of our tracking technologies, researchers typically build virtualenvironments that work within a single physical room or a portion of a room. Even distributedvirtual reality systems usually interconnect two or more such indoor spaces. Meanwhile, ascomputers grow ever smaller and faster, mobile computing is becoming an increasingly importantpart of our daily lives, accompanying us wherever we go, outdoors, as well as indoors.What will it take for virtual reality to move outdoors and finally see the light of day? And, whyshould we care? Within the virtual reality research community, work on augmented reality hasalready begun to explore outdoor environments-tracking using computer vision, gyroscopes,accelerometers, compasses, and GPS; and experimenting with (barely) wearable testbeds. I willdiscuss why virtual reality (especially in the form of augmented reality) and mobile computing are asynergistic combination, and will provide an overview of the research problems that must beaddressed for mobile augmented reality systems to play a major role in our future.Among the issues that I will review are overcoming physical and aesthetic barriers to mobilityand wearability; tracking and registration of heads, hands, bodies, and other objects; renderingvirtual objects in the real world; and developing sufficiently high quality displays. Equallyimportant is the design of head-tracked user interfaces that are well suited to mobility. Wearablesystems will need to support collaboration among mobile users, facile interaction with real andvirtual objects, and coordination across a wide range of heterogeneous displays and devices. Keyhere is the volatile nature of mobile interactions-users continually move into and out of thepresence of other users, devices, and objects, and rapidly change tasks. Furthermore, augmentedreality makes it possible for real and virtual objects to share the same display space, creating thepotential for a variety of visually confusing relationships as objects overlap and occlude each other.Avoiding these problems will require that the virtual world be redesigned and laid out on the fly, tomaintain desired visual relationships between virtual objects and other real and virtual objects.","PeriodicalId":105245,"journal":{"name":"IEEE Virtual Reality, 2003.
