Head-mounted display-based virtual reality sickness-reducing technology is defined.
Measuring quality of experience (QoE) aims to explore the factors that contribute to a user's perceptual experience including human, system, and context factors. Since QoE stems from human interaction with various devices, the estimation should be started by investigating the mechanism of human visual perception. Therefore, measuring QoE is still a challenging task. In this standard, QoE assessment is categorized into two subcategories which are perceptual quality and virtual reality (VR) cybersickness. In addition, deep learning models considering human factors for various QoE assessments are covered, along with a reliable subjective test methodology and a database construction procedure.
This standard defines a framework for the Tactile Internet, including descriptions of various application scenarios, definitions and terminology, functions, and technical assumptions. This framework prominently also includes a reference model and architecture, which defines common architectural entities, interfaces between those entities, and the mapping of functions to those entities. The Tactile Internet encompasses mission critical applications (e.g., manufacturing, transportation, healthcare and mobility), as well as non-critical applications (e.g., edutainment and events).
This standard specifies the general technical framework, components, integration, and main business processes of augmented reality systems applied to mobile devices, and defines its technical requirements, including functional requirements, performance requirements, safety requirements and corresponding test methods. This standard is applicable to the design, development, and management of augmented reality enabled applications or features of applications on mobile devices.
This standard defines an architecture required to implement a virtual reality system that can simulate responses to possible disasters in physical spaces, where users can actually move around with six degrees of freedom, for training. This reference architecture includes the physical-to-virtual component that transfers sensor data in the physical space to the virtual world, the virtual-to-virtual component that conveys the data between virtual world objects, and the virtual-to-physical component that transfers the simulated responses in the virtual world to actuators in the physical world.
This standard specifies the requirements and test methods for the motion to photon (MTP) latency that causes virtual reality (VR) sickness while users are using the virtual reality content. This standard is applicable to VR content related with software, hardware, and human factors regarding MTP latency.
ISO 19141:2008 defines a method to describe the geometry of a feature that moves as a rigid body. Such movement has the following characteristics.(a) The feature moves within any domain composed of spatial objects as specified in ISO 19107.(b) The feature may move along a planned route, but it may deviate from the planned route.(c) Motion may be influenced by physical forces, such as orbital, gravitational, or inertial forces.(d) Motion of a feature may influence or be influenced by other features, for example:- The moving feature might follow a predefined route (e.g. road), perhaps part of a network, and might change routes at known points (e.g. bus stops, waypoints).- Two or more moving features may be pulled together or pushed apart (e.g. an airplane will be refuelled during flight, a predator detects and tracks a prey, refugee groups join forces).- Two or more moving features may be constrained to maintain a given spatial relationship for some period (e.g. tractor and trailer, convoy).ISO 19141:2008 does not address other types of change to the feature. Examples of changes that are not addressed include the following:(a) The deformation of features.(b) The succession of either features or their associations.(c) The change of non-spatial attributes of features.The feature's geometric representation cannot be embedded in a geometric complex that contains the geometric representations of other features, since this would require the other features' representations to be updated as the feature moves. Because ISO 19141:2008 is concerned with the geometric description of feature movement, it does not specify a mechanism for describing feature motion in terms of geographic identifiers. This is done, in part, in ISO 19133.
ISO/IEC 18023-2:2006 specifies the abstract syntax of a SEDRIS transmittal. Actual encodings (e.g. binary encoding) are specified in other parts of ISO/IEC 18023.
This document specifies the abstract class of a media thing (MThing), which is a basic component to construct the Internet of media things. The MThing class contains the basic APIs to:(a) discover other MThing(s) in the network;(b) connect/disconnect MThing(s); and(c) support transactions (e.g. payments) using media tokens between MThings.
This document provides context, motivation, and use case descriptions for a set of MPEG standards that collectively deliver media directly to render-based applications such as game engines with a renderer component, or standalone renderers. Emerging examples where such applications are especially relevant include “metaverse” applications and immersive displays where such displays provide an interface to components (e.g., renderers) of existing game engines; e.g., Unreal Engine by Epic Games, Inc. and Unity by Unity Technologies. This document:(1) describes the motivators leading to the development of new MPEG standards that facilitate the streaming of media to render-based applications;(2) provides an overview of a media workflow from content production to content distribution;(3) provides general information on relevant components of render-based systems including game engines, and renderers;(4) differentiates between visual media distributed for video-based applications and visual media distributed to render-based applications;(5) identifies key components and resources (compute, storage, or network) comprising a heterogeneous set of immersive displays and other render-based applications; and(6) documents use cases for end-to-end interoperability, including Audio, Video, Graphics and Systems aspects for render-based systems and applications.
This document specifies the conformance and reference software implementing ISO/IEC 23093-3. The information provided is applicable for determining the reference software modules available for ISO/IEC 23093-3, understanding the functionality of the available reference software modules, and utilizing the available reference software modules. Furthermore, this document provides means for conformance testing, i.e. bitstreams - XML descriptions that conform or do not conform to ISO/IEC 23093-3.
ISO/IEC 18023-1:2005 addresses the concepts, syntax and semantics for the representation and interchange of environmental data. It specifies: - a data representation model for expressing environmental data; - specifications of the data types and classes that together constitute the data representation model; and- an application program interface that supports the storage and retrieval of environmental data using the data representation model.ISO/IEC 18023-1:2005 also specifies topological, rule-based, and other constraints that ensure appropriate data can be available for applications that rely on automatically generated behaviours when interacting with environmental data.
