Designing a first prototype touchscreen interface for older novice users

This paper describes a part of the process of generating a touchscreen interaction design prototype for older novice users of digital technology, for subsequent evaluation with representative users. The rationale for attempting to develop such an interface is discussed, and the major decisions taken to reach the prototype are highlighted. Unexpected issues of application of guidelines and research results to a specific interface design are discussed. The steps the ergonomists took to generate new design ideas brought to light the problems the designers face in their work routine. The paper highlights these issues as well as suggests a topic to be explored in future research to facilitate the design of more inclusive interfaces.
