Involving elderly users in design: techniques to collect preferences for Interactive Digital Television

Area of Science:

• Human-Computer Interaction
• Gerontology
• Digital Media Studies

Background:

• The increasing elderly population requires innovative solutions for social inclusion and engagement.
• Traditional digital television (IDTV) interfaces may not adequately cater to the specific needs of older adults.
• Aging is associated with changes in perception, cognition, and motor abilities that impact technology use.

Purpose of the Study:

• To explore the potential of Interactive Digital Television (IDTV) for active audience engagement among elderly individuals living at home.
• To identify and implement effective techniques for involving elderly users in the design and requirement collection phases.
• To understand elderly users' preferences for IDTV content and interaction methods.

Main Methods:

• User-centered design approach focusing on elderly participants.
• Adaptation of requirement elicitation techniques to address age-related sensory, cognitive, and motor changes.
• Exploration of content and interaction modality preferences through user studies.

Main Results:

• Specific solutions were developed to facilitate elderly users' contributions during the design process.
• Key preferences regarding IDTV content types were identified.
• Preferred interaction modalities suitable for older adults were determined.

Conclusions:

• IDTV can be effectively utilized to foster active audience participation among homebound elderly individuals.
• Tailored design methodologies are crucial for successfully incorporating the needs and preferences of aging users.
• Understanding user-specific content and interaction preferences is vital for developing inclusive digital television experiences for seniors.
