Development and testing of a Thai website accessibility evaluation tool
This research addresses theimportant problem of a lack of a method to help with the evaluation of the accessibility of Thai websites and web applications by developing and evaluating a new method and online tool, WebThai2Access, with developers, experts, and disabled users. The tool was evaluatedby30 developers, 30 hearing impaired people, 30 visually impaired people, and 30 elderly people. The developers evaluated the websites whereas experimental tasks were given to each disabled group based on the problems they had accessing web information. The developers found WebThai2Access very usable and the 15 test criteria were reliable for evaluating websites. The average 95% upper and lower confidence limits of the developer scores were plus or minus 10% for both Pantip and YouTube websites and plus or minus 3% for the blind association website. The average 95% upper and lower confidence limits were plus or minus 0% for the visually impaired users, plus or minus 2% for the elderly users, and plus or minus 5% for the hearing impaired users. The results therefore showed that WebThai2Access was very accessible and could be used reliably by developers and their evaluations predicted the accessibility of websites for disabled users reasonably well.

Abstract

This research addresses theimportant problem of a lack of a method to help with the evaluation of the accessibility of Thai websites and web applications by developing and evaluating a new method and online tool, WebThai2Access, with developers, experts, and disabled users. The tool was evaluatedby30 developers, 30 hearing impaired people, 30 visually impaired people, and 30 elderly people. The developers evaluated the websites whereas experimental tasks were given to each disabled group based on the problems they had accessing web information. The developers found WebThai2Access very usable and the 15 test criteria were reliable for evaluating websites. The average 95% upper and lower confidence limits of the developer scores were plus or minus 10% for both Pantip and YouTube websites and plus or minus 3% for the blind association website. The average 95% upper and lower confidence limits were plus or minus 0% for the visually impaired users, plus or minus 2% for the elderly users, and plus or minus 5% for the hearing impaired users. The results therefore showed that WebThai2Access was very accessible and could be used reliably by developers and their evaluations predicted the accessibility of websites for disabled users reasonably well.
