Computer-mediated reality. Art installation illustrating the mediated reality concept. First we display what's really there, and then this allows a computer to be inserted into the "reality stream" to modify it. Mediated Reality application running on Apple iPhone Computer-mediated reality refers to the ability to add to, subtract information from, or otherwise manipulate one's perception of reality through the use of a wearable computer or hand-held device[1] such as a smart phone. Typically, it is the user's visual perception of the environment that is mediated.
This is done through the use of some kind of electronic device, such as an EyeTap device or smart phone, which can act as a visual filter between the real world and what the user perceives. Computer-mediated reality has been used to enhance visual perception as an aid to the visually impaired. It has also been used for interactive computer interfaces.[2] Window managers[edit] One common window manager in mediated reality is the "Reality Window Manager" [3] Knowbotic Research. Knowbotic Research is a German-Swiss electronic art group, established in 1991. Its members are Yvonne Wilhelm, Christian Hübler and Alexander Tuchacek.
They hold a professorship for Art and Media at the University of the Arts in Zurich. History[edit] Yvonne Wilhelm (born 1962), Christian Huebler (born 1962), Alexander Tuchacek (born 1962) are based in Zurich Switzerland. The Knowbotic Research group has experimented with the intersection of technology, information and knowledge, interface, immersive virtual reality and networked agency. Knowbotic is a coinage that combined “knowledge” with “robot”, meaning intellectual agent on the Internet. Awards[edit] Knowbotic Research has been exhibited widely and has received several prizes, including: Two Prix Ars Electronica Golden Nicas (in 1994 and 1998)The Claasen Prize for Media Art and Photography, CologneThe international ZKM Media-art awardThe August Seeling-Award of Wilhelm Lehmbruck Museum [edit] References[edit] External links[edit] Map database management. Map database management stems from navigation units becoming more common in automotive vehicles (see Automotive navigation system).
They serve to perform usual navigation functions, such as finding a route to a desired destination and guiding the driver to it or determining the vehicle’s location and providing information about nearby points of interest. Moreover, they are playing an increasingly important role in the emerging areas of Location-based services, Active safety functions and Advanced Driver Assistance Systems.
Common to these functions is the requirement for an on-board map database that contains information describing the road network. Maintaining such a map database, including keeping it up to date and incorporating related information, is the subject of this article.

Interchange format[edit] Augmented reality. NASA X38 display showing video map overlays including runways and obstacles during flight test in 2000. Augmented reality (AR) is a live direct or indirect view of a physical, real-world environment whose elements are augmented (or supplemented) by computer-generated sensory input such as sound, video, graphics or GPS data. It is related to a more general concept called mediated reality, in which a view of reality is modified (possibly even diminished rather than augmented) by a computer. As a result, the technology functions by enhancing one’s current perception of reality.[1] By contrast, virtual reality replaces the real world with a simulated one.[2][3] Augmentation is conventionally in real-time and in semantic context with environmental elements, such as sports scores on TV during a match.
Technology[edit] Hardware[edit] Hardware components for augmented reality are: processor, display, sensors and input devices. Display[edit] Head-mounted[edit] Eyeglasses[edit] HUD[edit] EyeTap[edit] Ubiquitous computing. Ubiquitous computing (ubicomp) is a concept in software engineering and computer science where computing is made to appear everywhere and anywhere. In contrast to desktop computing, ubiquitous computing can occur using any device, in any location, and in any format. A user interacts with the computer, which can exist in many different forms, including laptop computers, tablets and terminals in everyday objects such as a fridge or a pair of glasses. The underlying technologies to support ubiquitous computing include Internet, advanced middleware, operating system, mobile code, sensors, microprocessors, new I/O and user interfaces, networks, mobile protocols, location and positioning and new materials.
This new paradigm is also described as pervasive computing, ambient intelligence,[1] ambient media[2] or 'everyware'.[3] Each term emphasizes slightly different aspects. Core concepts[edit] Dust: miniaturized devices can be without visual output displays, e.g. Layer 1: task management layer. Information and communications technology. Information and communications technology (ICT) is often used as an extended synonym for information technology (IT), but is a more specific term that stresses the role of unified communications[1] and the integration of telecommunications (telephone lines and wireless signals), computers as well as necessary enterprise software, middleware, storage, and audio-visual systems, which enable users to access, store, transmit, and manipulate information.[2] The term Infocommunications is sometimes used interchangeably with ICT.
In fact Infocommunications is the expansion of telecommunications with information processing and content handling functions on a common digital technology base. For a comparison of these and other terms, see.[6] The ICT Development Index compares the level of ICT use and access across the world.[7] Global Costs of IT[edit] The WSIS Process and the stocktaking process[edit] The second phase took place from November 16 through 18, 2005, in Tunis, Tunisia. See also[edit] Infotainment. Infotainment is "information-based media content or programming that also includes entertainment content in an effort to enhance popularity with audiences and consumers. "[1] The term can also refer to the hardware/software products and systems which are built into, or can be added to vehicles in order to enhance driver and/or passenger experience. It is a neologistic portmanteau of information and entertainment, referring to a type of media which provides a combination of information and entertainment.
According to many dictionaries[2] infotainment is always television, and the term is "mainly disapproving. Infotainment is not to be confused with infotisement, a form of advertisement. Criticism[edit] The label "infotainment" is emblematic of concern and criticism that journalism is devolving from a medium which conveys serious information about issues affecting public interest, into a form of entertainment which happens to have fresh "facts" in the mix.
Apocrypha[edit] See also[edit] [edit] Virtual globe. NASA World Wind, an open-source virtual globe with stars and advanced atmosphere & sunlight effects A virtual globe is a 3D software model or representation of the Earth or another world. A virtual globe provides the user with the ability to freely move around in the virtual environment by changing the viewing angle and position.
Compared to a conventional globe, virtual globes have the additional capability of representing many different views on the surface of the Earth. These views may be of geographical features, man-made features such as roads and buildings, or abstract representations of demographic quantities such as population. On November 20, 1997, Microsoft released a popular offline virtual globe in the form of Encarta Virtual Globe 98, followed by Cosmi's 3D World Atlas in 1999. The first widely publicized online virtual globes were NASA World Wind (released in mid-2004) and Google Earth (mid-2005).
