Abstract

Nowadays, several guidelines support the development of mobile applications that intend to consider aspects of accessibility. These guidelines describe a set of requirements that must be considered during, for example, the specification of user interfaces and interaction strategies. However, these guidelines do not consider the influence of the response time of interactive systems regarding their accessibility. The aim of the present work is to identify concrete cases that show this influence, generating knowledge that can support the extension of the guidelines. Two initial cases are discussed together with possible strategies that could avoid interaction troubles for visually impaired users.

Keywords: Accessibility, Usability evaluation, Mobile devices.
