Quali-Quantitative Review of the Use of Multimodal Interfaces for Cognitive Enhancement in People Who Are Blind

摘要

Visual disability has a major impact on people's quality of life. Although there are many technologies to assist people who are blind, most of them do not necessarily guarantee the effectiveness of the intended use. As part of research developed at the University of Chile since 1996, we investigated the interfaces for people who are blind regarding a gap in cognitive impact. We first performed a systematic literature review concerning the cognitive impact evaluation of multimodal interfaces for people who are blind. Based on the papers retrieved from the systematic review, a high diversity of experiments was found. Some of them do not present the data results clearly and do not apply a statistical method to guarantee the results. We conclude that there is a need to better plan and present data from experiments on technologies for cognition of people who are blind. Moreover, we also performed a Grounded Theory qualitative-based data analysis to complement and enrich the systematic review results.
