Implication

Randomized trial explores task performance in older adults using smartphone app design, indicating design features impact usability.

Key Points

  • This study aims to evaluate the effectiveness of age-friendly smartphone interfaces for older adults during product searches.
  • Two-stage study with 52 older adults across two experiments.
  • Experiment 1 compared age-friendly to standard interface performance using WeChat and Pinduoduo.
  • Experiment 2 tested menu configurations and vibration feedback on a custom product-search task.
  • Two-level menu configuration resulted in 56.7% fewer clicks and 30.7% shorter completion time compared to the flat configuration.
  • Vibration feedback led to 20.2% fewer ineffective clicks during tasks.
  • Delayed recall was linked to completion time but weakened when adjusted for age and sex.
