Most software applications contain graphics such as charts, diagrams and maps. Currently, these graphics are designed with a ``one size fits all" approach and do not cater to the needs of people with disabilities. Therefore, when using software with graphics, a colour-impaired user may struggle to interpret graphics with certain colours, and a person with dyslexia may struggle to read the text labels in the graphic. Our research addresses this issue by developing a framework that generates adaptive and accessible information graphics for multiple disabilities. Uniquely, the approach also serves people with multiple simultaneous disabilities. To achieve these, we used a case study of public space floorplans presented via a web tool and worked with four disability groups: people with low vision, colour blindness, dyslexia and mobility impairment. Our research involved gathering requirements from 3 accessibility experts and 80 participants with disabilities, developing a system to generate adaptive graphics that address the identified requirements, and conducting an evaluation with 7 participants with disabilities. The evaluation showed that users found our solution easy to use and suitable for most of their requirements. The study also provides recommendations for front-end developers on engineering accessible graphics for their software and discusses the implications of our work on society from the perspective of public space owners and end users.

翻译：大多数软件应用包含图表、示意图和地图等图形。当前，这些图形采用"一刀切"的设计方式，未能满足残障人士的需求。因此，在使用包含图形的软件时，色觉障碍用户可能难以辨识特定颜色的图形，而阅读障碍人士则可能无法阅读图形中的文字标签。本研究通过开发一个能够为多重残障人士生成自适应且无障碍信息图形的框架来解决该问题。独特之处在于，该方法同样适用于同时患有多种残障的人群。为实现这一目标，我们以通过网页工具呈现的公共空间平面图为案例，与四类残障群体（低视力者、色盲者、阅读障碍者和行动障碍者）展开合作。研究过程包括：向3名无障碍专家和80名残障参与者收集需求，开发可生成满足需求的自适应图形系统，并组织7名残障参与者进行评估。评估结果表明，用户认为我们的解决方案易于使用且能满足大部分需求。本研究同时为前端工程师提供了在软件中工程化实现无障碍图形的建议，并从公共空间所有者与终端用户视角探讨了该项工作的社会影响。
