Specialist Task Force 540:
User-centred terminology for existing and upcoming ICT devices, services and applications

Latest News:

The ETSI Guide has received ETSI Member approval and has been published on August 2019 as scheduled. The document can be found here.

Previous events: 

On October 17, 2018, STF540 organized a first, open, public consultation and review workshop in Stockholm, hosted by the Swedish National Body ITS. A draft of the ETSI Guide is available here. Participation was free of charge. Further details are available here.

On March 19-20, we organized an "electronic Open-house", an digital participation opportunity combined with physical presence at ETSI, offering multiple review, Q&A and future work discussion opportunities to interested stakeholders.

The updated, final Committee draft is available through the link below for comments during the ongoing ETSI TC Human Factors approval.

What we do

This EC/EFTA co-funded project spans over a two-year period (September 2017 to August 2019) with the aim to develop a set of user-centred, accessible and harmonized terminology recommendations intended to improve the overall user experience and accessibility. The work is covering commonly used, basic ICT features of current and upcoming ICT devices, services and applications, focusing on a mobile context, in five languages: English, French, German, Italian and Spanish.

ETSI Guide (EG) 203 499 is planned for publication in August 2019. A detailed time plan, including the open and free availability of several publicly accessible ETSI Guide drafts for stakeholders’ feedback, is provided below.

For more details, see our Terms of Reference

Why we do it

Users, unfamiliar with the terminology, technical meaning or intended functionality of mobile ICT may be reluctant to use their current and future devices, services or applications and may miss out on potential benefits. This also prevents them from exploiting the true potential of ICT and hinders the uptake and use of services, including those of societal relevance. 

How we do it

This ongoing development work is conducted in collaboration with ICT experts and other relevant stakeholders. It is based upon a combination of desk research, expert knowledge and an industry-wide collaboration, consultation, review and consensus process, in three main phases: 

1.    Identification of objects and activities to be addressed;
2.    Collection of terms used by major providers (top5 or as possible); and
3.    Analysis, selection, consolidation, consensus and presentation of the recommended terms (ongoing now).

The most common functional areas covered by the work were identified, selected and grouped into 16 functional areas:

Four device-related functional areas: General; Accessibility; Telephony; and Photography.
Twelve service- and application-related functional areas: General; Messaging services; Media services; Societal services and communications; Social media; Banking and payment services; eHealth services; Travel services; Navigation and maps; Games; Searching and browsing; and Tools and miscellaneous.

For each functional area, relevant and representative providers in the top market segments were selected and the most frequently used, specific terms, objects and activities of the respective functional areas were collected in five languages. The methodology applied is described in more detail in the draft ETSI Guide available further down on this page.

Stakeholders are consulted through available national and international channels. Face-to-face meetings are altered with electronic consultation, conference presentations, public free workshops, face-to-face discussions and targeted presentations since (see “Time plan” below for further details). Written input is always gladly accepted.


ETSI STF540 is developing ETSI Guide EG 203 499: “Human Factors; User-centred terminology for existing and upcoming ICT devices, services and applications” that proposes a user-centered, harmonized terminology of mobile ICT device (4 groups) and service and applications (12 groups) functions, focusing on communication in mobile contexts of use, in the five largest EU/EFTA languages: English, French, German, Italian, and Spanish. 

Details of our progressed approach, developed through an open consultation and collaboration process, are provided and reflected in the available drafts of ETSI Guide EG 203 499. 
The formal project timeframe is August 2017 to August 2019, development work taking place from November 2017 until June 2019. 

Time plan

The main development work takes place from November 2017 to April 2019, after which the ETSI TC Human Factors and Member Approval Vote process, deliverable adjustment and publication follows on, until July 2019.

Dissemination and promotion activities, informing about the free availability of ETSI Guide EG 203499, encouraging the free use of our deliverable will conclude the project by early August 2019.
