This paper evaluates the accessibility features of the iPhone’s user interface for visually impaired (VI) users. This research was conducted in collaboration with Pervasive Technology Systems, Cambridge, UK. A qualitative approach was used to test the accessibility and to study the Human-Computer Interaction (HCI) of iPhone 3G model designed and developed by Apple. The research was carried out by direct observations of a focus group, conducted during one-to-one tutoring session. The multiple case-study approach was adopted to increase the reliability of data, with the help of a team of researchers and tutors to reduce bias. The focus group of fifteen visually impaired adults was given different tasks and activities to perform over multiple sessions. At the end of theses sessions a questionnaire was also conducted. The research concluded that 80% of the participants felt confident using iPhone user interface. This study demonstrates that it is possible to create accessible devices like iPhone for visually impaired users. The technological resources can only be fully compliant if site manufacturers, designers and developers consider accessibility requirements as an essential element.
