36-558: A 3D Model (assuming one is available on http://www.example.com/myModel.dae ) on a Trackable, like a fiducial marker, located at http://www.example.com/myMarker.jpg : Wikitude Wikitude was a mobile augmented reality (AR) technology provider based in Salzburg, Austria. Founded in 2008, Wikitude initially focused on providing location-based augmented reality experiences through the Wikitude World Browser App. In 2012,

54-531: Is built on a generic object model that allows serialization in several languages. Currently, ARML defines an XML serialization, as well as a JSON serialization for the ECMAScript bindings. The ARML object model consists of three main concepts: The definition of a Feature is reused from the Geography Markup Language (GML) and describes the physical object that should be augmented. The physical object

72-553: Is compatible with Android, iOS, and Windows operating systems, and it has also been optimized for various smart eyewear devices. The Wikitude app pioneered the use of a location-based approach in augmented reality. As of September 21, 2023, no new subscription purchases can be made, and existing subscriptions cannot be renewed. Support for the Wikitude SDK has ceased on September 21, 2024, at which time all associated Wikitude services have been shut down. Wikitude initially entered

90-650: Is described by a set of metadata, including an ID, a name and a description. A Feature has one or more Anchors. An Anchor describes the location of the physical object in the real world. Four different Anchor types are defined in ARML: Geometries describe the location of an object through a set of fixed coordinates. WGS84 (latitude, longitude, altitude) is used as the default coordinate reference system, other arbitrary coordinate reference systems can be supplied if required. ARML allows 0- (Point), 1- (LineString) and 2-dimensional (Polygon) geometries. Geometry Anchors reuse

108-720: The Augmented Reality Markup Language (ARML). This format is now called ARML 1.0 and serves as an input format for the Wikitude World Browser. In late 2011, Martin Lechner, Wikitude's CTO and the main driver of the ARML initiative, established the Augmented Reality Markup Language 2.0 Standards Working Group (ARML 2.0 SWG) within the OGC. Its goal was to create an internationally accepted standard for Augmented Reality, based on

126-522: The Object Tracker can work with three-dimensional structures and objects (tools, toys, machinery, etc.). Opinions differ as to whether the location-based approach of augmented reality implemented by Wikitude can be considered as augmented reality . There is also concern for the accuracy of the GPS, compass and motion sensors used to calculate the position of the virtual objects. Inaccuracies could accumulate to

144-773: The company restructured its proposition by launching the Wikitude SDK, a development framework that uses image recognition and tracking, and geolocation technology. In September 2021 Wikitude announced that it has been acquired by Qualcomm . The Wikitude SDK (software development kit) serves as a foundational product for the company. First launched in October 2008, the SDK includes image recognition and tracking, 3D model rendering, video overlay, location based AR. In 2017 Wikitude launched its SLAM technology (Simultaneous Localization And Mapping) which enables object recognition and tracking, as well as markerless instant tracking. The versatile SDK

162-444: The definition of a Trackable is abstracted and split into two parts, a Tracker and its associated Trackables . A Tracker describes the technology (or algorithm) with which its associated Trackables should be tracked, using URIs identifying the algorithm. The Trackable itself describes the pattern the algorithm should look for in the video stream. Example: A natural feature tracker and an associated Trackable RelativeTo Anchors allow

180-426: The definition of a location relative to other Anchors or the user's position. The former allows the setup of a scene and the location of all included virtual objects based on a single Anchor, like a Trackable placed on a table. The latter allows for scenarios where the actual location of the user is irrelevant. The virtual objects are simply placed around the user, regardless of his or her physical location. Contrary to

198-439: The devices' screen or lenses. One of the notable examples of location-based AR is Pokémon Go. Since August 2012, Wikitude also features image recognition technologies that allow for tracker images to trigger augmented reality technology within the app. The software identifies relevant feature points of the target image (also known as marker). This allows to overlay and stick augmentations in specific position on top or around

216-578: The ideas of ARML 1.0 and similar formats. During ISMAR in Atlanta in November 2012, the first ARML 2.0 specification was officially published, making ARML 2.0 an official OGC Candidate Standard. ARML 2.0 is reusing ideas, structure, syntax and semantics of the following existing and widely used standards: In addition, the following, ARML-independent initiatives also deal with creating standards for Augmented Reality environments: The following example describes

234-463: The image. In 2017 Wikitude launched its SLAM technology. Instant Tracking , the first feature using SLAM, allows developers to easily map environments and display augmented reality content without the need for target images (markers). Object Recognition is the latest addition based on SLAM, with the launch of SDK 7. The idea behind Object Recognition and Tracking is very similar to Image Tracking, but instead of recognizing images and planar surfaces,

252-467: The market with its geo location AR app. The Wikitude app pioneered the use of a location-based approach in augmented reality. For location-based augmented reality, the position of objects on the screen of the mobile device is calculated using the user's position (by GPS or Wi-Fi ), the direction in which the user is facing (by using the compass ) and accelerometer . Augmentations can be placed at specific points of interest and afterwards viewed through

270-468: The previous three Anchor types, ScreenAnchors do not describe a location in the 3-dimensional virtual scene. Instead, they define an area on the device screen, allowing for status bars and the like. VisualAssets describe the appearance of the virtual objects in the augmented scene. ARML allows various kinds of VisualAssets to be described, including plain text, images, HTML content and 3D models. VisualAssets can be oriented (either to always automatically face

288-538: The syntax as defined in GML3. As an example, the following snippet defines the location of the Wiener Riesenrad . Trackables are patterns that are searched, recognized and tracked in the video screen coming from the camera of the device. A wide variety of different tracking technologies exist, including QR codes , Natural features , 3D and Face Tracking. As all these tracking types use different algorithms and technologies,

324-465: The user, or to maintain a specific static orientation) and scaled. Additionally, visibility conditions can be applied (i.e. the Asset is only visible on the screen if the distance to the user is within certain boundaries). In late 2009, Wikitude (formerly Mobilizy), the creators of the Wikitude World Browser, started an early initiative on creating a format all AR Browsers at that time could adhere to, called
