WITHDRAWN: The impact of input modality on user experience by age group: based on self-service terminal

Abstract

The current interaction of self-service terminal lack an effective way that is consistent with the needs of older adults. Touch input is a frequent modality, sometimes the only modality, used in self-service terminal, which may not be beneficial to some older users. This study aims to investigate the effects of input modality (touch, voice, eye control) and age (young people, pre-seniors, and seniors) on the task performance and cognitive load of users operating a prototype self-service terminal. Task performance and cognitive load significantly differed across input modalities and participant ages. For touchless modalities appropriate for pandemic environments, this research indicates both eye control and voice inputs are suitable for young people, and voice input appropriate people over the age of 55. For non-pandemic environments, the touch input was found suitable for users below the age of 55. For those over 55, voice input is a better choice.
