Exploring Accessibility Features and Plug-ins for Digital Prototyping Tools

Many digital systems are found to be inaccessible and a large part of the issue is that accessibility is not considered early enough in the design process. Digital prototyping tools are a powerful resource for designers to quickly explore both low and high fidelity design mockups during initial stages of product design and development. We evaluated 10 popular prototyping tools to understand their built-in and third-party accessibility features. We found that accessible design support is largely from third-party plug-ins rather than prototyping tools’ built-in features, and the availability of accessibility support varies from tool to tool. There is potential to improve accessible design by increasing the potential for accessibility to be consider earlier in the design process.
