EFFECTIVENESS, PRODUCTIVITY AND SATISFACTION OF PERSONS WITH SIGHT AND MOTOR DISABILITIES WHEN USING DYNAMIC TEXT{ONLY PAGES
Keywords:
usability, accessibility, text transcoder, text-only pageAbstract
Text transcoders are web{server systems that produce, on the y, a text{only version of a web page requested by a user of a browser. Although the potential benets of text transcoders are multifaceted and discussions on appropriateness of text transcoders to produce accessible versions of web sites are still ongoing, at the moment the impact of transcoded pages on disabled web users has not yet been scientically studied. This paper describes an experiment aimed at evaluating usability of web pages pro- cessed by a text transcoder and used by 29 disabled persons. Results based on subjective and objective data show how usability changes, and which results can be generalized to a broader population.
