Marker: A term used by programmers of magic mirror augmented reality systems to denote the pattern a camera will recognize. See glyph

GPS

GPS: GPS is an acronym for Global Positioning Satellite. Devices with GPS built-in are aware of their location on the surface of the earth. This information can be useful in augmented reality systems because it allows the AR system to know what the “real” reality of the device is, pull in correlating data (like nearby map features, weather, other GPS data encoded objects and so on). In conjunction with a compass, GPS can have a sense of what direction the device is facing–perhaps enough to place useful data or artwork into a live video overlay.; GPS-based AR applications require the system to know the location of the viewer, usually approximated as the location of the device used to run the AR application. This is in contrast to Glyph-based AR application, which require possession of a Glyph to display the data or augmentation.

Papervision3D: A Flash code framework for making simple three-dimensional (3D) art on the web. Many augmented reality systems use this framework to present artwork mapped to an AR glyph.

FLARToolkit: A Flash code framework based on the ARTools codebase. FLARToolkit surfaces the code required for Flash applications to use webcams to recognize augmented reality glyphs.

Magic Lens

Magic Lens: A mode of augmented reality in which the audience is looking at view-finder-like screen which presents a images of the world with digital content superimposed. Like a first-person view of the real world with digital artwork overlayed.; This is in contrast to the Magic Mirror mode of augmented reality.

Magic Mirror

Augmented Reality Magic Mirror: A type of augmented reality (AR) system/rig where a glyph is displayed to a camera and a video display shows the video captured by the camera with the augmented reality data overlayed. The end result is that the video display looks something like a mirror–showing the user, the glyph and the augmented reality data all at once. This contrasts with the Magic Lens type of augmented reality.; For example: A glyph is distributed on a postcard. The user logs into an augmented reality website. The website activates the user’s webcam and asks the user to present the glyph. The user shows the glyph to the webcam. The augmented reality website then displays a 3D model or other digital information mapped over the glyph in the live webcam display.

Glyph

Augmented Reality (AR) Glyph: A Glyph is a printed symbol used in Augmented Reality applications to allow access to digital content. AR glyphs are often referred to as “Markers” in technical writing and code.; Augmented reality applications that use glyphs take advantage of a hardware camera to recognize the image in the glyph, then align the artwork in relation to that glyph.; For example, an augmented reality iPad application would use the camera in the iPad2 or later to recognize a printed image (the glyph) and then place artwork over that image in the video display of the iPad.; Glyph-based augmented reality applications require possession of the glyph or image. This is one of the key differences between Glyph and GPS based augmented reality.; An example of an augmented reality glyph from a children’s media project.
This augmented reality glyph looks like a heavy black square outline around a black and white image of Dusty, a Dogsharks character. From a children's augmented reality application.
Note that the artwork features Dusty, a character from Dogsharks. The heavy black outline of a glyph is what the augmented reality application uses to determine how to place the “augmented” artwork in the video. The artwork in the center of the outline is what the augmented reality application uses to determine which artwork to display. This glyph could be placed anywhere (a book, a sticker, a billboard and so on) and anyone possessing the AR application that recognizes the glyph could access the augmented content.
