	Augmented Reality Home Pages - Introduction
		Augmented reality can be applied so that the surgical team can see the CT or MRI data correctly registered on the patient in the operating theater while the procedure is progressing.
		Augmented reality systems are expected to run in real-time so that a user will be able to move about freely within the scene and see a properly rendered augmented image.
		The U of R augmented reality system requires no a priori metric information about the intrinsic and extrinsic parameters of the camera, where the user is located in the world or the position of objects in the world.

	Augmented reality - Wikipedia, the free encyclopedia
		Augmented reality (AR) is a field of computer research which deals with the combination of real world and computer generated data.
		History of AR In the original publication (Wellner et al., 1993) which coined the term, (Computer-) Augmented Reality (abbreviated AR) was introduced as the opposite of virtual reality: instead of diving the user into a synthesized, purely informational environment, the goal of AR is to augment the real world with information handling capabilities.
		Additionally, augmented reality is itself a special case of the more general concept of mediated reality (med-R), in the sense that mediated reality allows for the perception of reality to be augmented, deliberately diminished, or otherwise modified.

	AugmentedReality
		Augmented Reality, by its very nature, is a highly inter-disciplinary field, and Augmented Reality researchers work in areas such as signal processing, computer vision, graphics, user interfaces, wearable computing, mobile computing, computer networks, distributed computing, information access, information visualization, software engineering, and the design of new displays.
		Augmented Reality is a new research activity which explores various approaches to augment a user's view of the real world with additional information.
		Augmented Reality can be applied in many sectors of industry, e.g., for repairing and maintenance of complex machines and facilities, visualizing sensor or simulation data, and for interior design.

	Augmented Reality
		This is in contrast to virtual reality (VR) in which the user is completely immersed in an artificial world and cut off from the real world.
		In order to combine real and virtual worlds seamlessly so that the virtual objects align well with the real ones, we need very precise models of the user's environment and how it is sensed.
		Realistic merging of virtual objects with a real scene requires that objects behave in physically plausible manners when they are manipulated, i.e., they occlude or are occluded by real objects, they are not able to move through other objects, and they are shadowed or indirectly illuminated by other objects while also casting shadows themselves.

	Augmented and Mixed Reality (Site not responding. Last check: 2007-11-05)
		Unlike virtual reality that replaces the physical world, AR enhances the physical reality by integrating virtual objects into the physical world which become in a sense an equal part of our natural environment.
		The goals of these demonstrations were, first, to demonstrate how augmented reality can be be used to dramatically enhance face to face collaboration in a way that could be used by novices with no training.
		Because in augmented reality environments visitors can see physical world, virtual objects and each other, several visitors can easily join around the mixing table and “jam” together, passing musical sequences to each other in the same manner in which we would pass everyday objects.

	Trend: Augmented Reality Check (Site not responding. Last check: 2007-11-05)
		Virtual reality, in the form of computer-based simulations, has been written about quite frequently in learning publications—but much less attention has been paid to the learning potential of augmented reality.
		Virtual reality completely replaces the real environment and this makes it much more difficult for users to adapt.” In 5 or 10 years, he says, we will be using AR for “a number of everyday applications,” including training and learning.
		In short, augmented reality training is no different than other types in that it needs to be focused on solid instructional design and well thought-out cost-benefit analysis.

	Towards Augmented Reality Gaming (Site not responding. Last check: 2007-11-05)
		For example, the augmented reality hardware may seem to augment the senses of the player, giving him the ability to see through physical walls to virtual objects in the game, hear a whisper at great distances, see other players' "good" or "evil" auras to avoid deception, follow lingering ``scents'', or detect "dangerous" hidden traps.
		In an augmented reality game, if the positions of the users and the objects that the users might interact with are known through time as with active RFID transmitters [Want95], many inferences can be made about the "where, when, who, and what" of the players' interactions.
		While the implementation of autonomous agents in augmented realities is of interest [Wren95], the typical ``birds-eye'' view of this type of game will have to be modified to address the player's living in the environment himself while monitoring his agents.

	Look Beneath the Surface with Augmented Reality - Overlaying digital information on real-world views literally opens up ...
		Augmented Reality AR, a technology based on virtual reality, superimposes virtual data onto real-life data, producing a mixture of the two environments.
		Often, AR augments data stored in several media and relays the information to the user, dependent on position in relation to the information source.
		However, this is a relative accuracy and so we completed testing of the output and how it relates to real world data, and confirmed that it supplied the requisite accuracy for the AR system.

	EDUCAUSE \| Resources \| Resource Center Abstract
		Augmented reality adds information and meaning to a real object or place.
		To the extent that instructors can furnish students with a broad context for understanding the real world, students are more likely to comprehend and remember what they are learning.
		Through exposing students to an experiential, explorative, and authentic model of learning early in their higher education careers, augmented reality may help shift students from passive to active learning modes and thus become more successful learners.

		While promising, Augmented Reality is barely at the demonstration phase today, and its full potential will not be realized until several technical challenges are overcome.
		The real and virtual objects must be properly aligned with respect to each other, or the illusion that the two coexist will be compromised.
		The result is that in most Augmented Reality systems, the virtual objects appear to "swim around" the real objects, instead of staying registered with them.

		Like virtual reality, augmented reality is becoming an emerging platform in new application areas for museums, edutainment, home entertainment, research, industry, and the art communities using novel approaches which have taken augmented reality beyond traditional eye-worn or hand-held displays.
		In this book, the authors discuss spatial augmented reality approaches that exploit optical elements, video projectors, holograms, radio frequency tags, and tracking technology, as well as interactive rendering algorithms and calibration techniques in order to embed synthetic supplements into the real environment or into a live video of the real environment.
		Augmented Reality is different from Virtual Reality in that part of the scene is "real" and part of the scene is computer generated.
