Where Is Siri? The Accessibility Design Challenges for Enterprise Touchscreen Interfaces

摘要

Accessibility design on office products is essential to providing independence and equal employment for people with all abilities. In this paper, we reported findings from a usability evaluation with 12 blind users on the keyboard navigation and voice guidance designs on a Lexmark multifunctional printer. Results of this study indicated that visually impaired users were confused by a number of issues associated with the current design. They expected mature accessibility solutions such as VoiceOver and Siri on the touchscreen devices in workplaces. Design recommendations were proposed to address the usability concerns identified in this study. However, to improve accessibility designs on enterprise products, user experience designers still need to overcome challenges such as supporting users with different disabilities and to cope with constraints from development cost and schedules.
