Abstract
Figure 1: CoSight, a Chrome extension developed as a design probe to explore how lightweight interface nudges might encourage accessibility contributions from sighted video viewers when watching and commenting. The prototype augments YouTube video pages with features inspired by Fogg's Behavior Model [24], including color labels to highlight accessibility gaps (sparks), hints and references to guide contributions (facilitators), and reminders at key moments (signals).
