Abstract(s)
Účel – Při vizuální komunikaci dat v médiích, vědě i vzdělávání musíme brát na zřetel, že jisté procento příjemců bude limitováno ve svém vizuálním vnímání. Znevýhodnění vizuálního vnímání mohou být různorodá a pohybují se na širokém spektru od běžných krátkozrakostí/dalekozrakostí a poruch barvocitu, se kterými je možné se vypořádat relativně jednoduše, až k úplné ztrátě vizuálního vnímání, tedy slepotě. Ta dosud není ve vizualizační komunitě příliš často řešena, přestože vytváří zásadní informační bariéru. Design/metodologie/přístup – Příspěvek je pojat jako koncepční článek, který přináší syntézu poznatků z dosavadních prací a výzkumů v konkrétních tématech a prezentuje je skrze pohled nového kontextu tak, aby poskytl odrazový můstek pro další výzkum, který by měl zaplnit současná palčivá bílá místa. Výsledky – Koncepční článek přináší syntézu dosavadních debat a přístupů k překonávání bariér v oblasti vizuálního vnímání vizualizací a nahlíží na ně v širším kontextu. Jádrem textu jsou pak otázky o smysluplných podobách a přístupech k návrhu možných asistivních technologií i k jejich sociálním aspektům: příspěvek argumentuje, že prostá haptizace vizuálních předobrazů nemusí být dostatečnou cestou, je však nutné promýšlet i sociální aspekty zkoumaných řešení. Originalita/hodnota – Koncepční článek zpracovává v odborné vizualizační debatě upozaděné téma a je v druhém plánu také výzvou k dalšímu bádání v této zásadní problematice.
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.
