Reimagining iPhone Accessibility : A User-Centered Redesign for Improved Interaction and Usability

Abstract: Interacting with user interfaces has becoming something that everyone of all ages is doing whether it be using smart devices like phones and tablets, ordering at fast-food restaurants, watching movies on a plane, etc. With people of all ages interacting with interfaces, designers need to consider what limitations and barriers come with different age groups. This thesis aims to improve how elderly users interact with accessibility features on iPhones. The initial user testing conducted with elderly users discovered that many users are comfortable with their iPhones interface but that they could potentially benefit from accessibility features but are hesitant to explore. These insights were utilized in redesigning the interface for accessibility options on iOS, with the goal of creating a more inviting and user-friendly feature for elderly users. Final user testing showed that elderly users benefited from efficient interactions and instruction guides to make and perceive accessibility changes more effectively. The aim of the redesign was to address the users worries including confusion, hesitancy, and insufficient feedback.
