Presents a reflection on the assessment of mobile Web content for people with disabilities. It proposes a rationale for an evaluation framework considering: (1) the coherent merge of state of the art guidelines on Web accessibility and mobile best practices; and (2) the usage of current and prospective practices particularly for people with visual impairments. It also presents the preliminary results of a questionnaire that validates that rationale laying the grounds for a coherent evaluation approach.
