Diversity of Web accessibility in tourism: Evidence based on a literature review

BACKGROUND: In the tourism industry, people with disabilities (PwD) are frequently excluded from certain activities. The Internet is one of the most used information sources for planning tourism trips. However, the level of accessibility of information disseminated by the tourism industry through websites is still very low. OBJECTIVE: This study aims to explore the existence of diversity in Web accessibility in the tourism industry. METHODS: A systematic literature review method was used for the identification, selection, and evaluation of the published research on Web accessibility in the tourism industry. A set of 40 papers obtained from relevant scientific databases, and complemented with a snowballing effect, was synthesized and analyzed. RESULTS: Low levels of diversity of Web accessibility were found in the different tourism activities analyzed. The majority of studies published in this field are relatively recent and both manual and automated methods were employed. Web accessibility failures were mainly related to lack of connectivity with assistive technologies, complex layout, and navigation difficulties. CONCLUSION: The results obtained in this systematic literature review provide important contributions to increase knowledge of Web accessibility in the tourism industry. Moreover, practical and theoretical contributions can help Web developers creating more accessible tourism websites.
