Summary - Y.4245 (06/2026) - Requirements and capabilities of accessible service management using user accessibility preference profile for Internet of things services

Recommendation ITU-T Y.4245 defines requirements and capabilities for accessible service management (ASM) using user accessibility preference profiles (UAPP) for IoT services. It addresses the difficulty users with disabilities face when identifying, activating, and adjusting accessibility features across different IoT services and interfaces. Recommendation ITU-T Y.4245 specifies requirements for UAPP, including user identification, assistive technology information, preferred input/output modes, and UI/UX personalization. It also defines ASM requirements and capabilities to map IoT service accessibility features to user preferences, provide alternative formats for visual and auditory information, maintain settings across interfaces, and allow users to control or delete stored preferences.
