User Centred Design of a Smartphone-based Cognitive Fatigue Assessment Application

Abstract

This paper presents the user experience design approach taken for a mobile cognitive assessment tool. Taking a multidisciplinary approach with user centred assessment and feedback, the design of this tool was tailored to provide a usable and intuitive user experience. Key to user participation is ease of use and minimal time on task for participant engagement. To address this selected measures were carefully considered as to make the testing process simple and easy to engage with. Following a pre-validated, iterative design approach, an acceptable and engaging user experience was designed while retaining the ability to measure multiple aspects of a user's condition and environment. Accurate assessment of cognitive fatigue requires a wide range of environmental user data in order to understand the participant's current cognitive fatigue levels, therefore measures of physical, cognitive, social and emotional aspects were included within the application.
