Specialist Task Force 304:
AT Commands for Assistive Mobile Device Interfaces
Who we are:
News – TS 102 511 is Published
TS 102 511 was
published on the 31st of August, as planned! It is available at the
ETSI publications Download Area
The STF will now enter the
dissemination phase of the project. A strategy is being formulated that will
include, but will not be confined to the standardisation bodies. You are welcome
to contact us in case you have any ideas regarding dissemination activities !
What we do:
This EC/EFTA funded STF has produced the ETSI Technical Specification TS 102
511 Human Factor (HF); AT Commands for Assistive Mobile Device Interfaces.
The ETSI Technical Specification sets out the requirements for a number
of AT commands that can be used to enable assistive devices to interwork
satisfactorily with mobile terminals.
Why AT commands?
Because AT commands has matured from being a modem control technology to be a
comprehensive and pervasive middleware platform for mobile devices.
Why we do it:
An eEurope community that allows everyone fair access to
advanced information and communication services must include those citizens
whose disabilities are such that they cannot use devices designed for all. For
this group of users, often with multiple disabilities, it is crucial that
affordable, effective and usable assistive devices be available. These devices
must be able to easily connect to and interact with a multitude of fixed and
mobile ICT devices.
The work to achieve this will include the upgrading of
existing standards where the necessary Hayes AT commands do not exist (as recommended
in the ETSI TR 102 068, developed under the eEurope Action Plan). Consensus
building on this set of interface standards will be initialized in the
appropriate standards fora (e.g. 3GPP) in a process which involves manufacturers
of mainstream mobile devices, assistive devices and groups representing the user
with different special needs.
Standardized communication with assistive mobile devices
will improve the quality of life for millions of disabled citizens of the
European Union since it will open up possibilities for Small and Medium-sized
enterprises (SMEs) producing assistive devices.
It will also provide a basis for national regulatory
authorities to implement the Framework Directive (2002/21/EC), enable member
states to take specific measures for disabled end-users in order to ensure
access to publicly available telephone services in accordance with the Universal
Service Directive (2002/22/EC) and facilitate the implementation of the Public
Procurement Directive (2004/18/EC).

Meeting with ITU-T SG 16
The meeting was held on the 26 June - 6 July
2007 in Geneva. ITU-T SG16 understood that the desire is to see that the
documented commands are implemented in as many mobile devices as possible
for the benefit of those with disabilities. In order to achieve that
objective, it was agreed during the meeting to create an ITU-T work item on
The meeting was held on the 11-15 June. The final draft of TS 102 511
was discussed and amended. The meeting considered that a further two weeks
of review should be allowed before final approval.
Presentation and discussion, on the 24-25
April at ETSI.
Coordination with 3GPP SA1 working on Service
and system Aspects. The meeting was on the 27th of April in Madrid. The STF
had hoped to start a new 3GPP work item during this meeting, but
unfortunately this topic (access to mobile services by disabled users) is
not a priority within the 3GPP, so the suggested new 3GPP work item did not
receive support from the industry representatives at this meeting.
Coordination with the group responsible for
the Technical Specification 27.007; 3rd Generation Partnership Project;
Technical Specification Group Core Network and Terminals; AT command set for
User Equipment (UE). The meeting took place on the 28th of Mars

Milestone A (table of contents and scope) has been approved at HF#40, 16
June at ETSI.
Workshop, ICCHP 2006, 10th International Conference on
Computers, Helping People with Special Needs
The first workshop has been held on the 11th of July 2006. It has
been organized by STF 304 in association with the ICCHP 2006, 10th International
Conference on Computers, Helping People with Special Needs, July 12-14,

Stakeholder interviews at ISAAC
Stakeholders have been interviewed at the ISAAC (International Society for
Augmentative and Alternative Communication) conference. This year the 12th
Biennial International Conference of ISAAC was held on the 29-31st of July and
the 1-3rd of August in Düsseldorf, Germany. 48 exhibitors presented their
products at this year’s conference.
Workshop, Rehabilitation and day centre in Upper
The next workshop has been held on the 21st of September 2006 at
the Rehabilitation and day centre in Upper Springland, Perth in Scotland. People
with various disabilities have be asked to give their opinions about tasks
corresponding to different mobile technology usage scenarios.
