Augmented reality (AR) is an interactive experience that combines the real world and computer-generated content. The content can span multiple sensory modalities, including visual, auditory, haptic, somatosensory and olfactory. AR can be defined as a system that incorporates three basic features: a combination of real and virtual worlds, real-time interaction, and accurate 3D registration of virtual and real objects. The overlaid sensory information can be constructive, or destructive. This experience is seamlessly interwoven with the physical world such that it is perceived as an immersive aspect of the real environment. In this way, augmented reality alters one's ongoing perception of a real-world environment, whereas virtual reality completely replaces the user's real-world environment with a simulated one.
Mixed reality (MR) is a term used to describe the merging of a real-world environment and a computer-generated one. Physical and virtual objects may co-exist in mixed reality environments and interact in real time.
A tangible user interface (TUI) is a user interface in which a person interacts with digital information through the physical environment. The initial name was Graspable User Interface, which is no longer used. The purpose of TUI development is to empower collaboration, learning, and design by giving physical forms to digital information, thus taking advantage of the human ability to grasp and manipulate physical objects and materials.
Object hyperlinking is a term that refers to extending the Internet to objects and locations in the real world. Object hyperlinking aims to extend the Internet to the physical world by attaching tags with URLs to tangible objects or locations. These object tags can then be read by a wireless mobile device and information about objects and locations retrieved and displayed.
Mutual authentication or two-way authentication refers to two parties authenticating each other at the same time in an authentication protocol. It is a default mode of authentication in some protocols and optional in others (TLS).
Locative media or location-based media (LBM) is a virtual medium of communication functionally bound to a location. The physical implementation of locative media, however, is not bound to the same location to which the content refers.
A tracking system, also known as a locating system, is used for the observing of persons or objects on the move and supplying a timely ordered sequence of location data for further processing.
A virtual keyboard is a software component that allows the input of characters without the need for physical keys. The interaction with a virtual keyboard happens mostly via a touchscreen interface, but can also take place in a different form when in virtual or augmented reality.
Digital graffiti is the act of creating graffiti art using a computer vision system. Various groups and companies have pioneered digital graffiti since technology advances made it possible. Most notably is the Graffiti Research Lab based in the US with their L.A.S.E.R. Tag system.
Supranet is a term coined at the turn of the 21st century by information technology analysis firm Gartner to describe the fusion of the physical and the digital (virtual) worlds, a concept that embeds the "Internet of things" as one of its elements.
In computing, 3D interaction is a form of human-machine interaction where users are able to move and perform interaction in 3D space. Both human and machine process information where the physical position of elements in the 3D space is relevant.
Mobile technology is the technology used for cellular communication. Mobile technology has evolved rapidly over the past few years. Since the start of this millennium, a standard mobile device has gone from being no more than a simple two-way pager to being a mobile phone, GPS navigation device, an embedded web browser and instant messaging client, and a handheld gaming console. Many experts believe that the future of computer technology rests in mobile computing with wireless networking. Mobile computing by way of tablet computers is becoming more popular. Tablets are available on the 3G and 4G networks.
Spatial contextual awareness consociates contextual information such as an individual's or sensor's location, activity, the time of day, and proximity to other people or objects and devices. It is also defined as the relationship between and synthesis of information garnered from the spatial environment, a cognitive agent, and a cartographic map. The spatial environment is the physical space in which the orientation or wayfinding task is to be conducted; the cognitive agent is the person or entity charged with completing a task; and the map is the representation of the environment which is used as a tool to complete the task.
Nokia Point & Find is a mobile application, which lets you point your Nokia smartphone camera at objects and images you want to know more about, to find more information. It is a visual search technology that uses the phone's camera to obtain information by using image recognition to identify objects, images and places in the physical world in real-time. For example, one can use the application to find information on movies by pointing the camera at movie posters and then view reviews, or find tickets at nearby theaters. Its uses include city landmark tagging, barcode scanning for comparison shopping and 2D barcode scanning and finding information related to products and services based on content provided by third party publishers.
Affective haptics is the emerging area of research which focuses on the study and design of devices and systems that can elicit, enhance, or influence the emotional state of a human by means of sense of touch. The research field is originated with the Dzmitry Tsetserukou and Alena Neviarouskaya papers on affective haptics and real-time communication system with rich emotional and haptic channels. Driven by the motivation to enhance social interactivity and emotionally immersive experience of users of real-time messaging, virtual, augmented realities, the idea of reinforcing (intensifying) own feelings and reproducing (simulating) the emotions felt by the partner was proposed. Four basic haptic (tactile) channels governing our emotions can be distinguished:
- physiological changes
- physical stimulation
- social touch
- emotional haptic design.
WebAR, previously known as the Augmented Web, is a web technology that allows for augmented reality functionality within a web browser. It is a combination of HTML5, Web Audio, WebGL, and WebRTC. From 2020s more known as web-based Augmented Reality or WebAR, which is about the use of augmented reality elements in browsers.
The Augmented Reality Markup Language (ARML) is a data standard to describe and interact with augmented reality (AR) scenes. It has been developed within the Open Geospatial Consortium (OGC) by a dedicated ARML 2.0 Standards Working Group. ARML consists of both an XML grammar to describe the location and appearance of virtual objects in the scene, as well as ECMAScript bindings to allow dynamic access to the properties of the virtual objects, as well as event handling, and is currently published in version 2.0. ARML focuses on visual augmented reality.
In virtual reality (VR) and augmented reality (AR), a pose tracking system detects the precise pose of head-mounted displays, controllers, other objects or body parts within Euclidean space. Pose tracking is often referred to as 6DOF tracking, for the six degrees of freedom in which the pose is often tracked.
Commercial augmented reality (CAR) describes augmented reality (AR) applications that support various B2B (Business-to-Business) and B2C (Business-to-Consumer) commercial activities, particularly for the retail industry. The use of CAR started in 2010 with virtual dressing rooms for E-commerce.
Smart tourism is an important component of a smart city. Tourism is one of the major components of economic growth for communities worldwide. A key requirement of tourism has been to attract more and more tourists from different parts of the world. Smart tourism refers to the application of information and communication technology, such similar to the smart cities, for developing innovative tools and approaches to improve tourism. Smart tourism is reliant on core technologies such as ICT, mobile communication, cloud computing, artificial intelligence, and virtual reality. It supports integrated efforts at a destination to find innovative ways to collect and use data derived from physical infrastructure, social connectedness and organizational sources, and users in combination with advanced technologies to increase efficiency, sustainability, experiences. The information and communication technology tools used for smart tourism include IoT, mobile communication, cloud computing, and artificial intelligence. It combines physical, informational, social, and commercial infrastructure of tourism with such tools to provide smart tourism opportunities. The principles of smart tourism lie at enhancing tourism experiences, improve the efficiency of resource management, maximize destination competitiveness with an emphasis on sustainable aspects. It should also gather and distribute information to facilitate efficient allocation of tourism resources and integrate tourism supplies at a micro and macro level ensuring that the benefits are well distributed.
