Elementos de diseño que afectan la autoeficacia y la accesibilidad en las interfaces web para el adulto mayor

The Colombian population is aging because the birth and mortality have reduced. In an increasingly digitized world, the elderly has greater challenges for learning how to use digital systems. There are multiple studies of accessibility for older adults that suggest principles for designing web interfaces. However, they focus on perceptual limitations and motion control. Although it is made clear that the cognitive limitations of the elderly, such as memory problems, are the main factor that reduces accessibility, there are few studies that determine strategies or design principles to increase the usability of interfaces for older adults. For example, self-efficacy increases the technological confidence of older adults to use web interfaces. In this study, the aim was to identify elements of web interfaces that increase elders' self-efficacy and therefore accessibility to the web. The research of this article 0is of qualitative type and in its methodological development is based on grounded theory that, in the process, throws data in an emergent manner. It was found that elements related to size, representation, and used tools influence elders' self-efficacy. These results can be used by designers as an essential input in the design, development and implementation of web interfaces accessible to the elder.
