Working across domains
The IEC Systems Committee (SyC) concept covers different domains rather than a single one. The SyC AAL, for instance, brings together a multitude of technology experts from different areas, such as medical devices, consumer electronics, Internet of Things, computer systems and networks. These experts, who may come from a number of IEC Technical Committees (TCs), from other standards development organizations (SDOs) and from industry consortia such as Continua and other organizations like AALiance 2, work to address transversal standardization and broader system-wide issues.
Users come first!
IEC SyC AAL has been established to address concepts, products, services and systems combining technologies and social environment with the aim of improving the quality of AAL users’ lives. The AAL user is any person, of any age, who uses and/or benefits from AAL devices, systems or services.
The multiplicity of AAL technologies that the industry is developing, the large number of standards on the market today and the currently fragmented standardization landscape are challenges for the IEC in developing international and interoperable standards from which the AAL user can benefit.
The objective is that AAL users should, to the greatest extent possible, live a meaningful, active and independent life, be fit and in good health and be socially connected.
The SyC AAL work is represented through four levels of assistance and five use case categories.
Levels of assistance and AAL use case categories
AAL user domains cover four different levels of assistance:
- Level 0: Able to live independently with minimal assistance
- Level 1: Able to live independently, but some assistance is needed occasionally
- Level 2: Permanent assistance is needed with Instrumental Activities of Daily Living (IADL), which include, for example, the use of transportation, answering the telephone, shopping, cooking, housekeeping, cleaning, medication management, monetary management, etc.
- Level 3: permanent assistance is needed with Activities of Daily Living (ADL), which include the most basic human activities such as walking and moving around, going up a few steps of stairs, bathing, eating, clothing, continence, grooming, etc.
AAL use cases include a number of categories to deal with the required levels of assistance, for which there is a certain degree of overlap, i.e. categories may be relevant to several different levels of assistance and not limited to one. The categories identified so far are for:
- Prevention and management of chronic long-term conditions, e.g. prevention, early detection and efficient management of chronic long-term conditions; provision of AAL solutions for persons with identified risk factors or chronic conditions or both; enabling the wellbeing of people with chronic conditions and their communities, etc.
- Social interaction: enabling people of all ages to be active and socially connected in the society, from both a societal and personal perspective, effectively contributing to their health, overall quality of life and to social inclusion; including all systems for social connection and networking as well as the possibility for knowledge transfer
- Mobility: enabling mobility in terms of moving in the home and domestic environments; orientation and navigation, transportation and travel activities, etc.
- Health and wellness: effective management of health and wellness; prevention of functional decline and frailty; inclusion of all technical support, for example for fall detection and prevention, ambient sensors or actuators, alarm systems and location tracking; supporting sustainable care models
- (Self-)management of daily life activities at home: living independently for longer, with as little (professional) help as possible and with the choice and control over decisions, equipment and assistance affecting them; living actively in the sense of remaining in charge of their own lives and participating in society, etc.
The standards development work conducted by a SyC begins at the systems level rather than at the level of individual products, so supporting the investigation of more complex issues related to devices, services, systems, infrastructure and interoperability. As with a TC, a SyC can publish International Standards and other IEC deliverables such as Technical Reports and Technical Specifications but only to fill any gaps that may exist with other standards.
The SyC AAL currently consists of five Working Groups (WGs), one Project Team (PT) and two Chairman’s Advisory Groups (CAGs):
- WG 1: User Focus, covers all user-related issues of AAL products, systems and services; defines use cases that take into account the need of users (end users and organizations relevant to the SyC AAL); develop user requirements based on use cases; create risk management and contingency planning for these use cases; recommend product, systems, services and technologies needed for standardization.
- WG 2: Architecture and Interoperability, aims at coming up with a definition for an AAL reference architecture based on user needs, which allows interoperability at different levels by taking into account security and privacy issues
- WG 3: Quality and Conformity Assessment, focuses on quality criteria, developing testing cases, tools and Standards, working with IEC Conformity Assessment Board (CAB) to develop relevant schemes, and organize interoperability testing events (e.g. plugfests)
- WG 4: Regulatory Affairs, looks at AAL initiatives on national and regional levels with details on R&D projects and trials, at regulatory requirements on national and regional levels with details on AAL policies and at the relevant AAL organizations on national and regional levels such as those for the elderly and those with disabilities
- WG 5: AAL in the connected home environment, including the totality of appliances (e.g. household technology, home network, furnishings). Identifies standardization needs and new areas of standardization specific to the use of AAL systems, devices, services and technologies in the connected home environment; identify requirements for the integration of AAL assistant systems in connected homes (both new and existing homes)
- PT 60050-871: International Electrotechnical Vocabulary, was set up to develop the IEV part that deals with AAL terminology. The IEC TCs involved in AAL as well as the external stakeholders engaged in SyC AAL are involved in this PT.
- CAG 1: Coordination, is responsible for organizing and coordinating the work of the SyC AAL
- CAG 2: Strategy, develops the vision and long-term strategy of the SyC AAL by taking into account the emerging market trends and user needs
Wide network of liaisons
IEC SyC AAL is working closely with the following IEC TCs, Systems Committees, Advisory Committees and a Standardization Management Board (SMB) ad hoc Group, as well as with ISO/IEC JTC 1: Information Technology, the Joint Technical Committee set up by the International Organization for Standardization (ISO) and the IEC:
- IEC TC 59: Performance of household and similar electrical appliances
- IEC TC 61: Safety of household and similar electrical appliances
- IEC TC 62: Electrical equipment in medical practice
- IEC TC 79: Alarm and electronic security systems
- IEC TC 100: Audio, video and multimedia systems and equipment. TC 100 has set up a Technical Area, TA 16: Active Assisted Living (AAL), accessibility and user interfaces, to address AAL-specific issues related to audio, video and multimedia systems and equipment.
- IEC TC 124: Wearable Electronic Devices and Technologies, a newly-created TC
- ACART: Advisory Committee on Applications of Robot Technology
- ACSEC: Advisory Committee on Information security and data privacy
- SMB ahG 66: Smart Home/Office Building Systems
- ISO/IEC JTC 1: Information Technology, including WG 10: Internet of Things and Subcommittee (SC) 35: User interfaces
IEC SyC AAL also works with the following TCs, the Strategic Advisory Group (SAG) from ISO and the International Telecommunication Union Telecommunication Standardization Sector (ITU-T), and other organizations.
This wide network may extend in the future as further needs become apparent.
Set to deal with emerging trends
The systems approach is being used to address AAL issues because they cut across many fields of technology.
To do this, IEC SyC AAL has set itself the task of monitoring closely the following emerging trends:
- accessibility, user needs and user interface technologies
- Internet of Things and of People
- daily life autonomy and health support
- health informatics
- wearable smart devices
- disruptive technologies
- service robotics
- 5th generation Internet
- smart cities, including intelligent (smart) homes and smart office buildings
- security and personal data privacy
- Big Data and data analytics
Fast-growing AAL needs mean expanding role for SyC AAL
Increasingly, people of all ages are seeking wider and better access to technologies that allow them to live a more active and fulfilling life. These individuals may be elderly people who want to live independently and remain active longer, or those of any age who need to use or benefit from AAL devices, systems or services.
The proportion of elderly people in all societies is growing fast. In 2010, an estimated 524 million people were aged 65 or older, according to the US National Institute on Aging. By 2050, this number is expected to nearly triple, to about 1,5 billion.
Meanwhile, more and more individuals from other demographic groups are also seeking improved access to AAL products and services. The multitude of AAL technologies, products and services that can be used in the home and other environments, and the need to develop international and interoperable standards for these point to a very active agenda for the IEC SyC AAL in the future.
