Exploring Tangible Ways to Evaluate User Experience for Elders

Abstract

While user experience assessment enables understanding users' perception about a product, limitations have been encountered when elders use questionnaires to evaluate user experience. In this paper we present the design process of Aestimo, a tangible interface to assist elderly people when evaluating the user experience of interactive prototypes. Our prototype is a simplification of the AttrakDiff questionnaire, which gives a chance to record one's overall opinion (i.e., speech) and emotions. In addition, our design uses playful interaction styles that are familiar to the elderly. In a preliminary evaluation, elderly found Aestimo entertaining and easy to use. As future work, we aim to explore new materials in building Aestimo and to perform a comprehensive evaluation with several elders.
