Disability users’ evaluation of the web accessibility of SNS
Tóm tắt
Social network service (SNS) is an effective communication tool for the community of disabled people. However, there is a general paucity of research on web accessibility of SNSs. This study investigates web accessibility of four SNSs that are most popular among disabled people: Facebook, Twitter, Me2day, and Yozm. Eight disabled individuals were selected according to the type of disability: two with total blindness, two with low vision, two with brain lesions, and two with an upper extremity disability. The subjects were asked to perform four navigation-related tasks and ten general tasks for each SNS. The success rate of their performances and user satisfaction levels were then measured. The four SNSs, on average, attained a task success rate of 73 % and a user satisfaction score of 3.1 points (max. = 5), indicating that the disabled participants found the websites generally inconvenient. As a pioneering evaluative study of the web accessibility of major SNS sites for the disabled, this research contributes to both theory and practice.
