Publication: Accessibility for Individuals with Color Vision Deficiency

Individuals with Color Vision Deficiency (CVD) are often unable to distinguish between colors that individuals without CVD can distinguish. Recoloring tools exist that modify the colors in an image so they are more easily distinguishable for those with CVD. These tools use models of color differentiation that rely on many assumptions about the environment and user. However, these assumptions rarely hold in real-world use cases, leading to incorrect color modification by recoloring tools. In this doctoral consortium, I will present Situation-Specific Models (SSMs) as a solution to this problem. SSMs are color differentiation models created in-situ via a calibration procedure. This calibration procedure captures the exact color differentiation abilities of the user, allowing a color differentiation model to be created that fits the user and his/her environmental situation. An SSM-based recoloring tool will be able to provide recolored images that most accurately reflect the color differentiation abilities of a particular individual in a particular environment.
