Observation based analysis on the use of mobile applications for visually impaired users

Abstract

The current efforts to specify an usability guideline for accessible mobile applications are sparse and they are still far to present a concrete pattern. Our previous work carried out a broad survey to consolidate the findings of these efforts in a unique list with 36 requirements, 13 of them focused on vision impairments. In this paper we show the results of an observation-based analysis involving visually impaired volunteers, whose aim was to complement this review and confirm if the lack of these requirements in fact affects the use of mobile applications.
