Randomized trial examines how search layouts and visual styles impact performance and usability in older adults, suggesting design improvements for digital tools.
Key Points
This research aims to understand how different search layouts and visual presentations affect older adults' performance, usability, and cognitive load in mobile interfaces.
Mixed-factor experimental design with a 3 × 3 layout.
Conducted in China from March 2025 to April 2026.
Evaluated performance, usability, and cognitive load across various visual presentations.
Realistic visual presentations led to the best overall performance in evaluated dimensions.
List layout reduced task completion time but had a small effect size; it showed higher usability than other designs.
