ETSI has published EG 203 499, a new guide providing harmonized terminology for ICT devices and services in 19 major EU/EFTA languages to improve user interface consistency and accessibility. The document defines over 800 terms across functional areas such as telephony, photography, and navigation to reduce ambiguity caused by varying manufacturer labels. This standardized vocabulary aims to enhance usability for all users, particularly older adults or those with cognitive limitations, by ensuring consistent interactive elements across different platforms. The guide was developed through stakeholder collaboration and is freely available as a public resource to support terminology management systems and documentation.
