Preference Customization

The ability for users, particularly those using assistive technologies, to configure how they receive and interact with digital content based on their individual needs, preferences, and context. In accessibility, preference customization goes beyond basic assistive technology settings to encompass content-level preferences such as how much detail to include in alt-text descriptions, how to sort data in tables, what sound types to use for sonification, and which information to prioritize or exclude. Effective preference customization systems store settings centrally so they persist across websites and sessions, reduce configuration burden by importing from existing assistive technology settings, and make preferences available to content creators through standardized mechanisms. The concept is rooted in ability-based design, which tailors interfaces to individual abilities rather than requiring all users to consume content in the same way.
