Assessment of wizards for eliciting users’ accessibility preferences

Abstract

Tailoring of the user experience to each individual´s needs and preferences can lead to more accessible solutions. Adaptation has a key role on matching the systems characteristics with the user needs. This can be achieved with personalization (system-driven adaptation) or customization (user-driven adaptation). Personalization have good results on matching the user needs but raises concerns about privacy and how the information is retrieved. Customizations require that the user manually choose the preferences configuration. This article proposed two versions of a web wizard to elicit the accessibility preferences. One version was based on a quiz and the other one presented small interactive activities. The activities version was proposed to help reduce the burden of configuration by implicitly eliciting the user preferences through interactive small activities. The preliminary results with healthy participants suggest that both versions obtained a positive evaluation. However, there was no major difference between each wizard. The causes of these findings are discussed.
