A conceptual framework of students with visual impairments on website accessibility acceptance

摘要

Website accessibility is a key determinant of people with disabilities' acceptance. It is the key of making websites accessible to all, which covers all disabilities who affect access to the web. Web users including students with visual impairments can conveniently undertake a number of tasks that would be difficult or impossible, but many web applications are not accessible to them. Therefore, inaccessible online materials will lead students with visual impairments to fewer opportunities to learn and improve their learning outcomes. Based on many researches, it was found that the acceptance of website accessibility of students with visual impairments included web accessibility and vision impairment level. The purpose of this paper is to build a model based on Unified Theory of Acceptance and Use of Technology, that performance expectancy, effort expectancy, social influence, and facilitating conditions have positive effects on usage intention and acceptance behavior of website accessibility. This proposed model provides more understanding of the factors that could influence user acceptance in website accessibility. It also presents hypotheses and develops a structural equation model for further empirical study.
