The technologies of this document specified are description languages and vocabularies to describe virtual world objects. The adaptation engine is not within the scope of this document. This document specifies syntax and semantics of the tools used to characterize a virtual world object related metadata: Virtual World Object Characteristics (VWOC) as an XML Schema-based language which enables one to describe a basic structure of avatars and virtual world objects in virtual environments.
This standard specifies the terminology, technical reference framework, basic functional requirements, and technical indicators for the platform of blockchain-based e-commerce transaction evidence collecting, which is the foundation of digital business interactions.
This standard establishes a system designed to trade data through domain-independent and principled marketplaces operating under a unified architecture. It defines terminology, a reference model, and the roles and functions of data providers, data users, and data marketplaces. The standard provides an overview of the data trading system using its reference model.
This standard defines a trusted data circulation platform based on blockchain and distributed ledger technologies. The system overview of trusted data circulation platform is defined including underlying computation engine layer, blockchain and DLT core function layer, trusted data circulation layer, and interface layer. The functional modules, data circulation processes, technical and security requirements are specified. This standard includes recommendations for controlling the allowable purposes and amount of data utilization, and for data privacy and resistance to tampering during the relevant data operations.
This standard defines an evaluation model and evaluation index system for using blockchain in low carbon zones, combining carbon emission scenarios and zone types. This standard also defines the technical requirements and management requirements for using blockchain for low carbon zones, including carbon accounting data sources, data storage, data interaction, data accounting, emission factor database establishment, carbon accounting method selection and prediction.
This standard defines an application model and technical framework for green power identification based on blockchain. This standard also specifies the technical and operation management requirements of green power identification based on blockchain.
This document specifies an image-based representation model that represents target objects/environments using a set of images and optionally the underlying 3D model for accurate and efficient objects/environments representation at an arbitrary viewpoint. It is applicable to a wide range of graphic, virtual reality and mixed reality applications which require the method of representing a scene with various objects and environments. This document:
(1) defines terms for image-based representation and 3D reconstruction techniques;
(2) specifies the required elements for image-based representation;
(3) specifies a method of representing the real world in the virtual space based on image-based representation;
(4) specifies how visible image patches can be integrated with the underlying 3D model for more accurate and rich objects/environments representation from arbitrary viewpoints;
(5) specifies how the proposed model allows multi-object representation; and
(6) provides an XML based specification of the proposed representation model and an actual implementation example (see Annex A).
- physical and material parameters of virtual or real objects expressed to support comprehensive haptic rendering methods, such as stiffness, friction and micro-textures; and
- a flexible specification of the haptic rendering algorithm itself.
It supplements other standards that describe scene or content description and information models for virtual and mixed reality, such as ISO/IEC 19775 and ISO/IEC 3721-1.
The technologies specified in this document are description languages and vocabularies which describe sensorial effects. The adaptation engine is not within the scope of this document (or the ISO/IEC 23005 series). This document specifies syntax and semantics of the tools describing sensory information to enrich audio-visual contents: Sensory Effect Description Language (SEDL) as an XML schema-based language which enables one to describe a basic structure of sensory information; Sensory Effect Vocabulary (SEV), an XML representation for describing sensorial effects such as light, wind, fog, vibration, etc. that trigger human senses.
- Description languages and vocabularies to characterize devices and users;
- Control information to fine tune the sensed information and the actuator command for the control of virtual/real worlds, i.e., user's actuation preference information, user's sensor preference information, actuator capability description, and sensor capability description. The adaptation engine is not within the scope of this document. This document specifies syntax and semantics of the tools required to provide interoperability in controlling devices (actuators and sensors) in real as well as virtual worlds: Control Information Description Language (CIDL) as an XML schema-based language which enables one to describe a basic structure of control information;
- Device Capability Description Vocabulary (DCDV), an XML representation for describing capabilities of actuators such as lamps, fans, vibrators, motion chairs, scent generators, etc.;
- Sensor Capability Description Vocabulary (SCDV), interfaces for describing capabilities of sensors such as a light sensor, a temperature sensor, a velocity sensor, a global position sensor, an intelligent camera sensor, etc.;
- Sensory Effect Preference Vocabulary (SEPV), interfaces for describing preferences of individual user on specific sensorial effects such as light, wind, scent, vibration, etc.; and
- Sensor Adaptation Preference Vocabulary (SAPV), interfaces for describing preferences on a sensor of an individual user on each type of sensed information.
The present document presents and classifies industrial use cases for AR applications and services. It forms the basis for the requirements document to be drafted ETSI GS ARF 004: Augmented Reality Framework (ARF) Interoperability Requirements for AR components, systems and services.
