[U] the use of leaves, branches, paints and clothes for hiding soldiers or military equipment so that they look part of what surrounds them a camouflage jacket

[S or U] something that is meant to hide something, or behaviour that is intended to hide the truth Augmented reality (AR) is a term for a live direct or an indirect view of a physical, real-world environment whose elements are augmented by computer-generated sensory input, such as sound or graphics. 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. By contrast, virtual reality replaces the real-world with a simulated one. Augmentation is conventionally in real-time and in semantic context with environmental elements, such as sports scores on TV during a match. With the help of advanced AR technology (e.g. adding computer vision and object recognition) the information about the surrounding real world of the user becomes interactive and digitally manipulable. Artificial information about the environment and its objects can be overlaid on the real world. The term augmented reality is believed to have been coined in 1990 by Thomas Caudell, working at Boeing.[1] ideo games have been entertaining us for nearly 30 years, ever since Pong was introduced to arcades in the early 1970s.Computer graphics have become much more sophisticated since then, and game graphics are pushing the barriers of photorealism. Now, researchers and engineers are pulling graphics out of yourtelevision screen or computer display and integrating them into real-world environments. This new technology,...
