Abstract: Nowadays the number of mobile apps grows faster and faster. A good framework to assess the design for wheelchair accessible mobile apps is needed. This work uses three methods: design-based review, usability test and Analytic Hierarchy Process to understand user requirement design, performance of mobile apps andelements of user experience. Firstly a survey is conducted for comprehending existing mobile apps for wheelchair users in the market. A comparison between Wheel map and Visitors' Guide, which is designed by a group of PolyU students, has been done in performance test of our work. Second, we have conducted a survey to learn user requirements on content and functions of a wanted wheelchair accessible mobile app. Reasons why users use this kind of apps and existing problems are also investigated. For usability test, Visitors' Guide is used to collect feedbacks of user experience design. During the test, users performed operations on using the Visitors' Guide and concluded it is not easy to use. There are 25 problems reported at the end. Finally, testers were asked to mark every element of user experience. There are divide 21 elements into 5 parts: visual design, content, functionality, usability and social. The scores then formed a pairwise comparison matrix to calculate accumulative weights of the 5 parts for getting the possible relationships between each criterion. It is found out that performance and content are the two most significant criteria in user experience design.
