Governments have been investing considerable resources into making their services to citizens available through the Internet. However, people face barriers when accessing these e-services. Barriers affect people with disabilities to a greater extent. Taking into account the accessibility-in-use in addition to the required standards while designing these services would mitigate some of these issues. In this work, five e-services from the Spanish government were selected from among the most used ones and tested with fifteen participants, of whom ten participants belong to the group of people with low vision. Different qualitative and quantitative measures were analyzed to determine whether participants with low vision had more difficulties performing the tasks and to identify the design issues required to achieve improvement. The results highlighted some issues to be incorporated into the complexity and cognitive accessibility evaluations of e-services to anticipate difficulties (e.g., error prompting/prevention mechanisms). In addition, contributions to existing accessibility standards are proposed to be considered in the design of the e-services. [ABSTRACT FROM AUTHOR]

Web accessibility evaluation requires tests to be carried out with real users with disabilities performing real tasks or activities. To recruit an appropriate group of users and to observe their performance in the real world is difficult. For this reason we have developed RemoTest, a platform that assists researchers designing experiments, conducting remote and in-situ experimental sessions and analyzing the data gathered while the users are accessing the Web. Although this tool is oriented to experimenters, it is necessary to check whether the evaluation environments created by RemoTest are accessible or not to the users that participate in the tests. To this end, we conducted formal in-situ evaluations with 36 users with diverse characteristics. For this assessment, the participants were asked to install the platform, to fill in some automatically created questionnaires and to carry out several web navigation tasks. From the data gathered we analyzed the ease of the installation process, the accessibility of the automatically generated questionnaires, and user satisfaction. The results revealed the suitability of the platform for conducting inclusive experiments both in remote and in-situ contexts and provided guidelines on how the experiments should be set out.
