ISO/IEC 23005-2:2018

Overview

ISO/IEC 23005-2:2018 ("Information technology - Media context and control - Part 2: Control information") defines the syntax and semantics for control information used to describe devices, sensors and user preferences for controlling real and virtual environments. The standard specifies XML schema–based and binary representations that enable interoperability between actuators (lamps, fans, motion chairs, scent generators, etc.), sensors (light, temperature, GPS, intelligent cameras, etc.) and user preference descriptions. Note: the adaptation engine (decision logic) is explicitly out of scope.

Key topics and requirements

• Control Information Description Language (CIDL)
  • An XML schema–based language for expressing control information structure and semantics.
  • Includes provisions for both XML and compact binary representations (headers, mnemonics).
• Device Capability Description Vocabulary (DCDV)
  • XML representations to describe actuator capabilities (light, vibration, wind, heating/cooling, scent, fog, sprayer, colour correction, kinesthetic/rigid-body motion, mobile position, etc.).
• Sensor Capability Description Vocabulary (SCDV)
  • Interfaces and vocabularies for sensor capabilities (light sensors, temperature, velocity, GPS/global position, intelligent cameras).
• User preference vocabularies
  • Sensory Effect Preference Vocabulary (SEPV): per-user preferences for sensorial effects (light, wind, scent, vibration).
  • Sensor Adaptation Preference Vocabulary (SAPV): per-user preferences for how sensed data should be adapted or presented.
• Coordinate systems and semantics
  • Descriptions include reference/global coordinate definitions and base types/attributes to support spatially-aware devices and sensors.
• Interoperability focus
  • Consistent XML schema wrappers, semantic definitions, examples and binary encoding rules to enable cross-vendor control and integration.

Applications and who uses it

ISO/IEC 23005-2 is useful for organizations that need interoperable control of multimodal devices and sensors in both physical and virtual settings:

• IoT and smart home vendors - standardized capability descriptions for actuators and sensors.
• VR/AR and immersive media developers - consistent control of haptics, wind, scent, and motion systems.
• System integrators & middleware authors - building adaptation engines, orchestration layers and device drivers that consume standardized device/sensor descriptions.
• Accessibility and UX designers - mapping user sensory preferences to device control for personalized experiences.
• Standards bodies and implementers - aligning product interfaces to enable cross-platform media context and control.
