IEC TR 62907: Ambient Assisted Living Use Cases for Audio, Video and Multimedia

Introduction to IEC TR 62907

IEC TR 62907:2014 is a Technical Report that documents a comprehensive set of use cases related to Ambient Assisted Living (AAL) in the field of audio, video, and multimedia systems and equipment. As the global population ages, there is an increasing need for technology solutions that support independent living for elderly and disabled individuals. This technical report serves as a foundational reference for understanding how audio, video, and multimedia systems can be designed and deployed to address the unique challenges of AAL environments.

The report was developed by IEC Technical Committee 100 (Audio, Video and Multimedia Systems and Equipment) with contributions from multiple national committees and organizations including JEITA (Japan), ITU-T FG AVA, and the universAAL and GUIDE research projects. It provides a structured framework for identifying user needs, defining system requirements, and establishing a roadmap for future standardization activities in the AAL domain.

Use Case Scenarios and Application Framework

IEC TR 62907 defines an extensive taxonomy of AAL use cases organized by application domain and functional requirements. The major use case categories include communication and social interaction, entertainment, daily life support, safety and security, healthcare monitoring, and active aging support.

Connected TV as an AAL Hub

A particularly detailed use case involves the Connected TV serving as a central hub for AAL services. The TV set, already a familiar device in most homes, becomes the primary user interface for health monitoring, emergency communication, and daily information services. For example, monitoring TV power-on events and channel changes can serve as a passive indicator of the user’s activity and wellbeing. If no TV operation is detected for 24 hours, an automated alert is sent to healthcare providers or family members.

Health Monitoring and Telemedicine

The report describes use cases where smart devices such as smartphones with specialized applications function as pedometers, recording daily step counts, weight, and blood pressure. This data can be shared with healthcare providers for remote monitoring. The standard also covers telemonitoring scenarios where vital signs are measured through TV-based interfaces and communicated to healthcare professionals.

Engineering Design Principles for AAL Systems

IEC TR 62907 identifies four categories of accessibility principles that should guide the design of AAL systems: user-focused principles, interaction-focused principles, task-focused principles, and system-solution-focused principles.

User-focused principles emphasize the importance of designing for the full range of user abilities and recognizing that user capabilities may change over time. Systems should accommodate varying levels of vision, hearing, dexterity, and cognitive function.

Interaction-focused principles address the modalities through which users interact with AAL systems. The report advocates for multimodal interfaces that support voice, touch, gesture, and remote control input, allowing users to choose the most appropriate interaction method for their abilities and preferences.

Task-focused principles emphasize that common tasks should be achievable through multiple pathways, recognizing that a user who cannot perform a task one way may be able to achieve it through an alternative method.

Standards Gaps and Future Directions

The report identifies significant gaps in the existing standards landscape for AAL, particularly in the areas of interoperability between different vendors’ AAL systems, consistent accessibility features across devices, and standardized data formats for health monitoring information. These findings have directly influenced subsequent standardization work in IEC and other organizations.

Looking forward, the standard envisions a future where AAL systems are seamlessly integrated into everyday life through standardized interfaces and protocols. The concept of a “universal AAL platform” emerges from the use case analysis, where different service providers, device manufacturers, and healthcare organizations can interoperate through common middleware layers. This vision has influenced the development of subsequent standards including aspects of the ITU-T F.780 series for AAL systems and the ongoing work within IEC TC 100 on multimedia accessibility. The report specifically recommends that future standardization efforts focus on semantic interoperability, context-aware service discovery, and privacy-preserving data exchange mechanisms to enable the full potential of AAL technology.

From a business perspective, the standard provides valuable market intelligence for technology companies entering the AAL space. The detailed use case analysis reveals that the most commercially viable AAL solutions are those that leverage existing consumer devices (particularly smart TVs and smartphones) as the primary user interface, rather than requiring specialized and expensive dedicated hardware. This insight has significant implications for product strategy and market positioning in the rapidly growing ambient assisted living market, which is projected to serve over 200 million elderly individuals worldwide by 2030.

The system-solution-focused principles round out the accessibility framework by addressing the broader ecosystem in which AAL systems operate. These principles emphasize the importance of interoperability between different vendors’ systems, support for established communication protocols, and the ability to integrate with existing home automation and healthcare infrastructure. The report recommends that AAL system designers adopt service-oriented architectures with well-defined APIs to enable third-party service integration and future-proof system expansion. This architectural approach allows AAL solutions to evolve incrementally as new sensors, services, and care models become available, without requiring complete system replacement.
