Area of Science:

  • Human-Computer Interaction
  • Gerontology
  • Usability Engineering

Background:

  • Interactive television services offer diverse functionalities but present usability challenges.
  • Elderly users, a key demographic, experience significant barriers to accessing these services.
  • Current interfaces often lack intuitive design, hindering adoption and satisfaction.

Purpose of the Study:

  • To assess barriers elderly users face when accessing interactive television services.
  • To identify factors contributing to poor usability and desirability of these services for older adults.
  • To provide recommendations for improving the accessibility and user experience of interactive television.

Main Methods:

  • User-centered assessment of interactive television service accessibility.

  • Analysis of interaction operations and interface design across various services.
  • Evaluation of the impact of previous experience on user proficiency.

    • Main Results:

    • Significant barriers identified for elderly users regarding ease and desirability of access.
    • No positive correlation found between previous experience and improved interactive service usability.
    • Lack of explicit information and inconsistent operational rules identified as primary issues.

    Conclusions:

    • Current interactive television services present major accessibility challenges for elderly users.
    • Inconsistent design and inadequate information impede user proficiency and adoption.
    • Future interactive service design must prioritize explicit guidance and consistent interaction rules for broader accessibility.
