European foreword
This document (prEN 17999:2023) has been prepared by Technical Committee CEN/TC 293 “Assistive
products and accessibility”, the secretariat of which is held by SIS.
This document is currently submitted to the CEN Enquiry.
Introduction
Accessible systems for living independently (ASLI) can enable all users to control individual situations or
surroundings and engage in social activities inside and outside the home. Accessibility refers to making
systems for living independently accessible by adapting the design and functionality of products, and the
design and deployment of services, treated as a whole system. This is done to allow ease of use by any
user, regardless of characteristics, capabilities, preferences and accessibility needs or circumstances in
diverse contexts of use.
ASLI elements cover the products itself, services for installation and maintenance and accessible
information.
The objective of this document is to enhance the quality of life for everyone by ensuring satisfactory
accessibility of systems in everyday life and by improving both independence and full participation in
society. Accessible design is a sign of the times. This document can be used as a tool for accessible design
for ASLI.
Users normally move between different places, different rooms, the home, the car, public transport, the
workplace or educational places, shops and outdoor activities during a day. This requires interoperability
between mainstream solutions and ASLI products and services. See Annex B for more information.
Systems for living independently include solutions related to security, comfort, care, and for the control
of surroundings.
The focus of this document is on:
— ASLI products and ASLI services;
— ASLI that requires interoperability with mainstream systems;
— Accessible user information, instructions and support for ASLI;
— Services for ASLI for installation and maintenance.
Easily accessible ASLI will benefit all users and other stakeholders like family members, caregivers and
service providers.
The target groups of this document are:
— users;
— manufacturers and suppliers;
— developers, technologists and engineers;
— designers;
— regulators (authorities);
— procurers and distributors;
— insurance companies, public authorities and others financing ASLI;
— installation services, service providers;
— health professionals and providers (therapists);
— professional caregivers, informal carers and care assistants.
1 Scope
This document specifies requirements, recommendations, and guidance on aspects of accessible systems
for living independently (ASLI) in relation to technical solutions, service design, provision, and
information. This includes adapting design and functionality of systems, to allow ease of use by any user,
regardless of their abilities.
This document does not cover system-to-system communication.
This standard is not applicable to household and similar electrical appliances covered by EN IEC 63008
[8].

3.1
accessibility
extent to which products, systems, services, environments and facilities can be used by people from a
population with the widest range of user needs, characteristics and capabilities to achieve identified goals
in identified contexts of use (3.7)
Note 1 to entry: Context of use includes direct use or use supported by assistive technologies.
Note 2 to entry: The context in which the ASLI is used may affect its overall accessibility. This context could include
other products and services with which the ASLI may interact.
[SOURCE: EN ISO 9241-112:2017, definition 3.15 – Modified: Added Note 2 to entry from
EN 301 549:2021, 3.1 definition “Accessibility” Note 1, modified.]
3.2
system
product, service, or any combination of them with which the user interacts
[SOURCE: CEN-CENELEC Guide 6:2014, definition, 2.1 – Modified: Built environment is excluded in the
definition as it is not included in ASLI.]
3.3
accessible system for living independently
ASLI
product or service designed to meet multiple user needs in an interconnected way, in identified contexts
of use (3.7), that facilitates the performance of activities for users
Note 1 to entry: ASLI also refers to design of accessible service environments. This includes accessing, interacting
and using information about ASLI, as well as the ASLI itself.
Note 2 to entry: ASLI are not assistive technology (3.4) and not assistive products (3.5) but support interoperability
with them.
Note 3 to entry: ASLI are accessible if they are detectable, accessible and usable for persons with disabilities in the
usual way, without particular difficulties, and, as a rule, without help from others. An ASLI can be used with assistive
technologies.
3.4
assistive technology
AT
equipment, product, system, hardware, software or service that is used to increase, maintain or improve
capabilities of individuals
Note 1 to entry: Assistive technology is an umbrella term that is broader than assistive products.
Note 2 to entry: Assistive technology can include assistive services, and professional services needed for
assessment, recommendation, and provision.
Note 3 to entry: Where ICT does not support directly connected assistive technology, but which can be operated by
a system connected over a network or other remote connection, such a separate system (with any included assistive
technology) can also be considered assistive technology.
[SOURCE: EN 17161:2019, definition 3.2 – Modified: Note 3 to entry is added and copied from EN 301
549:2021, 3.1 definition “Assistive Technologies” note 3.]
3.5
assistive product
AP
