Full Description
Scope
This standard defines two description languages for expressing augmented reality (AR) learning experiences. This document shows how to represent activities conducive to developing or upgrading knowledge, skills, abilities, and other characteristics in a standardized interchange format. The interchange format links the representation of learning activities with their environment and context in the actual (or simulated) workplace, classroom, or other environment in which an AR-enhanced training system may execute them. The specification aims to lower entry barriers for authoring of learning experiences that involve interaction with the real world, sensors, computer vision, and web applications.
Purpose
This standard for augmented reality learning experience models (ARLEMs) provides an overarching integrated conceptual model and the corresponding data model specifications for representing activities, learning context, and environment (aka a??workplacea??), while linking with other data model components needed for AR-enhanced learning activities. The standard distinguishes slow-changing data for environment description from fast-changing data for step-by-step guidance. It defines the required data models and modeling languages and their bindings to Extensible Markup Language (XML; see XML 1.0) and JavaScript Object Notation (JSON; see ECMA-404). The purpose of this standard is to support the discovery, retrieval, transfer, and execution of AR-enabled learning content, thereby facilitating the creation of repositories and online marketplaces. Finally, the standard supports reuse and repurposing of existing (learning) content in a??mixeda?? experiences that combine real-world guidance with traditional media such as instructional video material or existing web applications and widgets.
Abstract
New IEEE Standard - Active.Augmented Reality (AR) promises to provide significant boosts in operational efficiency by making information available to employees needing task support in context in real time. To support according implementations of AR training systems,this document proposes an overarching integrated conceptual model that describes interactions between the physical world, the user, and digital information, the context for AR-assisted learning and other parameters of the environment. It defines two data models and their binding to XML and JSON for representing learning activities (also known as employee tasks and procedures) and the learning environment in which these tasks are performed (also known as the workplace).The interoperability specification and standard is presented in support of an open market where interchangeable component products provide alternatives to monolithic Augmented Reality-assisted learning systems. Moreover, it facilitates the creation of experience repositories and online marketplaces for Augmented Reality-enabled learning content. Specific attention was given to reuse and repurposing of existing learning content and catering to a??mixeda?? experiences combining real world learner guidance with the consumption (or production) of traditional contents such as instructional video material or learning apps and widgets.
