Investigating Accessibility Issues in Scheduling Coordination for Visually Impaired Computer Users

Although various scheduling methods have merits and demerits, accessibility issues, particularly for visually impaired users, have not been adequately clarified. Herein, we clarified accessibility issues with scheduling interfaces for visually impaired people and propose measures to deal with them. We first created four different types of modeled-scheduling interfaces. Then, we asked the visually impaired people who used a speech-to-text to register for a simulated schedule with these interfaces and answer questionnaires about their usability. The results revealed that the form with radio buttons for circle (○, available for participation), triangle (△, partially available), and cross mark (×, unavailable) and with a comment field for each candidate date received the highest usability with a significant score.
