Overview

Analyzes usability differences in mobile applications across age groups and modalities, suggesting improved design for older users.

Key Points

  • The research aims to analyze how age and modality impact mobile application usability, particularly for older users.
  • Evaluated usability across age groups under four modality conditions.
  • Included visual-only and visual-plus-auditory information presentations.
  • Conducted 12 trials with tasks: shopping, food ordering, and banking.
  • Assessed performance using completion time, error count, and subjective workload measures.
  • Older adults had longer completion times and higher error rates than younger adults.
  • Multimodal conditions with auditory feedback and help functions reduced errors for older users.
  • Significant interactions between age and modality were observed, favoring help-supported modalities for older adults.
