People with cognitive disabilities benefit from new computerized tools for maintaining social contacts. Their need for easy-to-use applications has been established. However, there is little research on improving usability evaluation methods with this user group. We conducted a case study with a group of users with cognitive disabilities. Pilot test findings indicated that a think aloud test would not work well with this user group. Therefore, instead of a conventional usability test, we conducted an informal walkthrough, in addition to classroom observation and interviews. Our study shows a need to collect data with several complementary methods, and to adjust the methods to suit the characteristics of the participants. Without observational methods, many usability problems would have been missed. Furthermore, the special characteristics of this user group have to be taken into account also in expert evaluation.

Web Accessibility for Cognitive and Learning Disabilities: A Review of Research-Based Evidence in the Literature
Paul R. Bohman, George Mason University
Though suppositions and recommendations abound, evidence-based research focusing on how to make web content accessible to people with disabilities is scarce. Only seven studies could be found that 1) directly observed people with cognitive disabilities, and 2) addressed cognitive disability access from a web content design perspective. Most of these studies lack the rigor and/or focus to provide any firm evidence or rationale for guidelines, notwithstanding the many recommendations promoted by these studies. Certain broad observations surfaced in multiple studies, such as user difficulties typing text, understanding context, and navigating within web sites. This literature review summarizes and critiques the seven relevant studies, then discusses potential reasons for the dearth of research-based studies about cognitive disability access to the internet.

This paper discusses the results of an online survey that investigates how children and young adults with Down syndrome use computers and computer-related devices. The survey responses cover 561 individuals with Down syndrome between the age of four to 21. The survey results suggest that the majority of the children and young adults with Down syndrome can use the mouse to interact with computers, which requires spatial, cognitive, and fine motor skills that were previously believed to be quite challenging for individuals with Down syndrome. The results show great difficulty in text entry using keyboards. Young individuals with Down syndrome are using a variety of computer applications and computer related devices, and computers and computer-related devices play important roles in the life of individuals with Down syndrome. There appears to be great potential in computer-related education and training to broaden existing career opportunities for individuals with Down syndrome, and there needs to be further research on this topic.

Web accessibility for individuals with cognitive deficits: A comparative study between an existing commercial Web and its cognitively accessible equivalent
ACM Transactions on Computer-Human Interaction (TOCHI) archive Volume 14 , Issue 3 (September 2007) Authors Javier Sevilla, Gerardo Herrera, Bibiana Martínez, Francisco Alcantud,University of Valencia, Spain
This article explains an alternative Web that has been constructed and tested on a sample of participants with cognitive disabilities (N = 20) with positive results encouraging us to dedicate more effort to fine tune their requirements regarding specific cognitive deficits and automating the process of creating and testing cognitively accessible web content. This alternative web implies the use of a simplified web browser and an adequate web design. Discussion of the need to have several levels of cognitive accessibility, equivalent (although not identical) content for this collective and the need for testable protocols of accessibility that support these people's needs is also included.
