Accessible Video-Call Application on Android for the Blind

Nutnicha Maneesaeng, Proadpran Punyabukkana, and Atiwong Suchato
Abstract—Video call function on smartphone, if properly implemented, can become a vital tool for people with visual disabilities to communicate with their assistants. We evaluated six popular video call applications on Android: Line, Skype, Hangouts, Tango, WeChat and Viber, and found that none of them was readily accessible for the blinds. Nonetheless, Tango outperformed their competitors as it could accomplish six out of seven mandatory tasks. In terms of efficiency, Hangout stood out because it was able to complete five out seven tasks with the least amount of time. Regarding effectiveness, no significant difference was found among the seven applications. We then analyzed their user interface and proposed a guideline as an extension to WCAG 2.0. Finally, we simulated a new UI based on our guideline and ensure accessibility and minimum swipes. The proposed design was evaluated by a blind user and found an improvement on five of seven tasks. The overall improvement was 53.15%.

Index Terms—Accessibility, video-call, smartphone, android, user interface, navigation, assistive technology.
