Usability of Mobile Devices for Elderly People

Abstract

This study investigated different usability-related aspects of small devices for the elderly. Based on previous work, the research selected some aspects from two instruments, the Technology Acceptance Model (TAM) and the DeLone and McLean Information Systems Success Model; the aspects under study were physical attributes, technology and system information, overall impressions, learning, dealing with problems, own capabilities, concerns, device capabilities, computing experience, and net benefits. The collection of data was carried out using an online survey with different aspects measuring the selected aspects of the study, related to the experience the participants had with the use of small devices. The survey was applied to 30 senior citizens in Ireland between the ages of 50 to 64. The results showed 4 of the constructs proposed had high reliability and significance (overall impressions, terminology and system information, net benefits, and concerns), and 1 failed as a construct (learning); statistical analysis identified other relationships between those constructs.
