Augmented Reality for Human Needs: An Ontology

Lecture Notes in Computer Science, 2012

This paper describes how semantic and Linked Data technology are incorporated into an Augmented Reality (AR) platform in the SmartReality project 1 and form the basis for enhanced AR mobile applications in which information and content in the user's surroundings can be presented in a more meaningful and useful manner. We describe how things of interest are described semantically and linked into the Linked Open Data cloud. Relevant metadata about things is collected and processed in order to identify and retrieve related content and services. Finally, the user sees this information intuitively in their Smart Reality view of the reality around them. We highlight how the use of semantics and Linked Data enables an AR experience which is more relevant for a user and with respect to what they have around them, and which can be automated and adapted at lower cost to content and application providers.

Augmented Reality aims to enhance the real world with computer-generated information. AR technology is both attractive and promising. Current AR experiences depend on external elements to launch, such as markers, images, and location. For an AR experience to be more personalized, this research proposes a scheme to trigger AR experiences based on human needs. This approach should enable human needs to be captured, and analyze them to select the most suited experiences that fulfill or aids in fulfilling needs. The contribution of this paper includes (1) a study of current AR technologies and triggers, (2) an analysis of human needs into measurable elements, and (3) a description of a needs-based AR application process with a demonstration of the process guidelines. The research presents a proof of concept prototype of a restaurant that satisfies the subsistence need for hunger. The results show the effectiveness of the guidelines in detecting human needs and recommending AR experience...

In this paper, a semantic model for distributed Augmented Reality services is presented. The services are built with the use of a novel Semantic Augmented Reality Ontology (SARO). SARO is based on semantic web standards (RDF, RDFS and OWL 2) and constitutes one of the main elements of the Contextual Augmented Reality Environments (CARE) approach. The model is used to build ubiquitous dynamic Augmented Reality presentations based on semantically described AR services in a contextual manner. In the paper, a visual design tool - the CARE Modeler - is also presented. The tool conforms to the SARO ontology and helps developers to model contextual Augmented Reality experiences. Finally, example presentations based on an AR service designed with the use of the tool are presented.

Due to the proliferation of smartphones, Augmented Reality applications have become more widespread nowadays. Augmented Reality browsers have especially enjoyed wide popularity within these applications. The physical environment could be extended by location-aware additional information using these browsers. At present, typically a specific data source is used by the current Augmented Reality browsers, even if there is an enormous amount of available data sources. The Semantic Web could help to bridge this problem. The goal of this work is to combine Augmented Reality and Semantic Web technologies in order to enhance the existing mobile Augmented Reality browsers using Semantic Web technologies. For this purpose, we utilize the advantages of the Semantic Web technologies such as data integration, unified data model as well as publicly available semantic data sources, among other things.

In our introduction is a state-of-the-art review in Augmented Reality (AR) Applications. Highly developed entertainment and critical games from both research and industry are introduced. The intangible, attention-grabbing, and flexible technology that provides a Simple Education Forum In this issue we present a summary of current AR applications outlining the challenges of designing a specific education-related domain. This research is part of an ongoing research project that aims to improve a better understanding of the design environment of AR applications that recognize the context of student smartphones. AR applications that can provide sensitive content to users while releasing them to explore context. To prevent misunderstanding, we refer to mobile AR as an AR type in which a mobile device (smartphone or tablet) is used to display and interact with visual content captured by a real-time camera server. of various educational levels. People with physical and mental disabilities are found all over the world; therefore, this paper introduces the Augmented Reality Application, conducted an indepth study of the popular taxpayer application we see based on in-depth reading / learning strategies and strategies published between 2014 and 2021 and concluded that current methods need to be differentiated in order to translate everything. data obtained correctly. Distinguishes progress in entertainment and critical sport in the education industry research. The unfortunate reality of taxpayers is seeing the sophisticated, attentive, and flexible technology that provides a simple educational platform, in this paper, we present the framework of the current AR smartphones program that helps vulnerable people to access information easily anywhere. This study is part of a larger study aiming at improving our understanding of the design environment for apps that identify student smartphone content. Mobile augmented reality is a sort of augmented reality object that uses a mobile device to display and interact with visual content in the real world that is covered by a real-time camera feed. The games and the unpopular reality of the taxpayers we encounter have been demonstrated to have a lot of learning power.

This article has a dual aim: firstly to define augmented reality (AR) environments and secondly, based on our definition, a new taxonomy enabling these environments to be classified. After briefly reviewing existing classifications, we define AR by its purpose, ie. to enable someone to create sensorymotor and cognitive activities in a new space combining the real environment and a virtual environment. Below we present our functional taxonomy of AR environments. We divide these environments into two distinct groups. The first concerns the different functionalities enabling us to discover and understand our environment, an augmented perception of reality. The second corresponds to applications whose aim is to create an artificial environment. Finally, more than a functional difference, we demonstrate that it is possible to consider that both types of AR have a pragmatic purpose. The difference therefore seems to lie in the ability of both types of AR to free themselves or not of location in time and space.

Abstract In this paper, we report on a prototype augmented reality (AR) platform for accessing abstract information in real-world pervasive computing environments. Using this platform, objects, people, and the environment serve as contextual channels to more information. The user's interest with respect to the environment is inferred from eye movement patterns, speech, and other implicit feedback signals, and these data are used for information filtering.

User Modeling and User-adapted Interaction, 2005

Ubiquitous computing is a challenging area that allows us to further our understanding and techniques of context-aware and adaptive systems. Among the challenges is the general problem of capturing the larger context in interaction from the perspective of user modeling and human–computer interaction (HCI). The imperative to address this issue is great considering the emergence of ubiquitous and mobile computing environments. This paper provides an account of our addressing the specific problem of supporting functionality as well as the experience design issues related to museum visits through user modeling in combination with an audio augmented reality and tangible user interface system. This paper details our deployment and evaluation of ec(h)o – an augmented audio reality system for museums. We explore the possibility of supporting a context-aware adaptive system by linking environment, interaction objects and users at an abstract semantic level instead of at the content level. From the user modeling perspective ec(h)o is a knowledge-based recommender system. In this paper we present our findings from user testing and how our approach works well with an audio and tangible user interface within a ubiquitous computing system. We conclude by showing where further research is needed.

Pervasive environments offer to software applications the possibility to interact with the reality in order to perceive the information surrounding the users and to adapt the environment and their own behavior. This problem is modeled as a set of context aware services which learn and augment the reality perceived by the user through her/his device. Application are enabled to perceive the information surrounding the users, to adapt the discovery and delivery of contents and software in order to optimize the user's satisfaction. We present a framework that implements the model to supports experts in the domain of the Cultural Heritage to augment the archaeological site with a set of multimedia contents which are delivered by innovative services to the visitors in order to guide their tour and to enhance their perception of the reality.

Augmented Reality (AR) applications have become widespread with the continued miniaturization of technology. With the increasing use of smart phones, which often provide increased processing power, enhanced and open software platforms, Augmented Reality has become instrumental in the way we perceive our surroundings and the information that it carries. Augmented Reality has also become a welcome visualization tool for many fields, not restricted to Human-Computer Interaction. In this paper we present a novel approach for building interactive interfaces using Augmented Reality and we give an example how one can use our framework for creating games to collect common sense knowledge from users. We present a software framework for ubiquitous Augmented Reality enhancement for human-computer interaction called UIAR (User Interface through AR). Our framework improves on four areas in Augmented Reality development that we currently see lacking.
