“…Many of the users did not use potentially helpful features in the screen-reading software (Theofanos and Redish, 2003). This finding is consistent with other studies that have found usability concerns with existing screen reader tools (Lazar et al, 2006(Lazar et al, , 2007.…”

“…As JAWS does not provide any programmatic means of directly accessing and recording this information, such studies would most likely use indirect measurements based on focus and navigation keystrokes. Evaluation of the impact of factors such as the number of links required to access items might provide empirical support for improvements to screen reader designs, which have been noted as a cause of difficulties for blind users Lazar et al, 2006;Lazar et al, 2007).…”

a b s t r a c tNumerous studies have investigated task performance times for selection from hierarchical menus, with structures containing many choices at each of a few levels (broad, shallow structures) generally outperforming structures containing fewer choices at each of many levels (narrow, deep structures). To see if these results applied to blind users who rely on screen reader software for computer access, we replicated an earlier published study, using 19 blind screen-reader users. Consistent with earlier studies, broader, shallow hierarchies outperformed narrow, deep hierarchies. Task performance times and hypertext lostness measures were correlated. Although further work will be needed to understand specific determinants of task performance rates, these results support the use of broad, shallow menus for blind as well as sighted users.

“…For example, if the shift key does one thing in one program, she has a hard time dealing with it if it does something else in a different application." (14) Frustration with computers has been documented for both the general computer users [Ceaparu et al 2004] and users with visual disabilities [Lazar et al 2006]. However, frustration may have greater impact on children with DS due to their limited cognitive and language abilities.…”

and ANT OZOK UMBCChildren with Down syndrome, like neurotypical children, are growing up with extensive exposure to computer technology. Computers and computer-related devices have the potential to help these children in education, career development, and independent living. Our understanding of computer usage by this population is quite limited. Most of the software, games, and Web sites that children with Down syndrome interact with are designed without consideration of their special needs, making the applications less effective or completely inaccessible. We conducted a largescale survey that collected computer usage information from the parents of approximately six hundred children with Down syndrome. This article reports the text responses collected in the survey and is intended as a step towards understanding the difficulties children with Down syndrome experience while using computers. The relationship between the age and the specific type of difficulties, as well as related design challenges are also reported. A number of potential research directions and hypotheses are identified for future studies. Due to limitations in survey methodology, the findings need to be further validated through hypothesis-driven, empirical studies.

“…Otro desafío que se presenta corresponde a que los navegadores de voz actuales omiten varias señales visuales, tales como estilos de texto y estructuras de páginas, y carecen de información significativa sobre el foco actual. Por otra parte, Lazar et al ha reportado que los usuarios de lectores de pantalla se sienten frustrados por muchas razones, incluyendo las dificultades técnicas de la navegación, y esto afecta negativamente a sus sentimientos y su desempeño [25].…”

RESUMENLa Web 2.0 propone nuevos desafíos para asegurar la "Accesibilidad Universal." Los diferentes tipos de usuarios Web se enfrentan con numerosas barreras de accesibilidad cuando interactúan con los diferentes tipos de sitios y aplicaciones que coexisten hoy en la Web 2.0, desde los denominados Simple Web Presence hasta las Rich Internet Applications o las Mobile Web Applications. En este escenario, la Accesibilidad Web es un atributo de calidad clave para propiciar el acceso a la información y a los servicios Web y proveer beneficios en el desarrollo de productos para la Web tales como la optimización de motores de búsqueda y la escalabilidad de aplicaciones multi-dispositivo. Los enfoques que asisten a la evaluación de la Accesibilidad de productos Web existentes, son semi-automáticos y requieren de la intervención humana en la detección de "falsos positivos"/"falsos negativos" y en la corrección de errores comprobados automática y manualmente. Para simplificar el proceso de toma de decisiones y reducir la intervención humana, las herramientas de evaluación, reparación, transformación y filtrado incorporan técnicas de automatización basadas en conceptos de inteligencia artificial. En este trabajo, se presentan y describen los enfoques y/o herramientas basados en agentes inteligentes y luego se propone una comparativa para analizar las contribuciones que estos hacen a la mejora de la accesibilidad, ya sea aplicando técnicas propias o las Web Content Accessibility Guidelines propuestas por el consorcio W3C.
