Data visualization as an information barrier for blind users

Vol.13,No.2(2021)

Abstract

Purpose – While communicating data in media, science, and education visually, we must consider that a certain percentage of recipients will be limited in their visual perception. The disadvantages of visual perception can be varied. They range from common refractive errors and colour blindness (these can be dealt with simply) to complete loss of visual perception, i.e. blindness. Blindness is still not often addressed in the data visualisation community, despite creating a significant information barrier.

Design/Methodology/Approach – The article is conceived as a conceptual one. It brings a synthesis of findings from past work and research on specific topics and presents them through the perspective of a new context – to provide a springboard for further research.

Results – The concept paper synthesises the debates and hitherto approaches to breaking down possible visual barriers in the perception of data visualisations, examining the topic in a broader context. At the heart of this examination are questions about meaningful forms and approaches to the design of assistive technologies and their social aspects. The article argues that simple haptisation of visual sources may not be sufficient and that the social aspects of the solution must also be considered.

Originality/Value – The concept article deals with a sidelined topic of data visualization debate. Equally important, it serves as a call to action for further research into this crucial issue.
