Challenges and Strategies in Mobile Phones Interface for elder people

Abstract: Mostly technological innovation depends on user interface design to enhance the technical complexity of products that match the end user requirements. The acceptance key of any technological product is user experience that how the user understands the end product. In design process a systematic approach is required to optimize user interface design to ensure optimal performance and usability testing. The main objective of this study is to identify the challenges and issues related to mobile phone software interface design in context of elderly people. The result of this study will support to mobile phone software interface designers and developers. During the investigation authors are trying to discover the usability problems faced by the elderly people using the current mobile phone software interface. The questionnaire technique was selected to collect the requirements from elderly about the mobile phone software interface. The finding of questionnaires was used to develop design guidelines for low fidelity prototype of mobile phone software interface. Moreover, usability testing was conducting to validate the design of low fidelity prototype. This thesis presents how we design mobile phone software interface for elderly with declining eyesight. Our system enables elderly declining eyesight to use their mobile phone by selecting different display modes.
