Health information display for elderly people: Interface attributes, usability, and emotional reaction

Abstract

This study investigated the four different interface formats of health information display — numeric, diagrammatic, imagery, and animated interface. Interface usability and emotional reaction were measured with SUS, QUIS, and SAM questionnaires. The performance of 30 young and elderly people was compared. Statistical results indicated that the information presented by the imagery and animated interfaces is easier to understand. Elderly people show a higher degree of acceptance with the numeric interface, regarding the information acknowledgment, emotional valence, and system usability.
