Customizing Interface Design for Users with Impairment Using a Paper Prototyping

Abstract

Impaired users are often digitally excluded due to their physical and/or cognitive limitations in accessing information and technology. This paper presents a usability study on the user interface design of a mobile phone application for users with impairment. In this study, a paper prototyping is used to examine the interface design, particularly on the size of an image, and the selection of fonts and background colors. An expert review was conducted to validate the design interface. Three experts on the physical impairment field took part in the study. The study findings confirmed earlier claim that bigger image sizes with a suitable font and background colors give a significant impact on user interaction
