Applying Usability Testing in the Evaluation of Products and Services for Elderly People

Abstract

A usability testing study on Self-help Health Checker, a human-machine interactive medical service system for the elderly people was introduced in this paper. The goal is to evaluate the product quality and users' experience when the product is at the very early stage of market launch. The test was conducted in the Lab of Psychology and Behavior Testing for the Elderly People, which consists of the Testing Room and the Observation Room. A professional audio-video system was set for recording the whole testing process. Seven subjects of different age and education background were invited to do the test. The methodology of Observation, Think Aloud, and Group Discussion were adopted. The test focused on the system stability and interface friendliness. Test results showed that this target product needs improvement in "degree of self-help" and "elderly user-friendliness" aspects.
