Application of the ISO 9241-171 Standard and Usability Inspection Methods for the Evaluation of Assistive Technologies for Individuals with Visual Impairments

This paper describes a usability evaluation process, based on ISO 9242-171 standard and inspection methods, to assess features to improve accessibility to in-formation services by individuals with visual impairments. A usability protocol based on checklists provided by the ISO 9242-171 standard together with con-sistency inspection and heuristics was applied to evaluate screen readers typically used by individuals with visual impairments. The results show that the approach proved to be adequate for supporting the assessment of accessibility features of the considered screen readers.
