**Digital Accessibility Advocate: A Geometry Problem That Shapes Smarter, Inclusive Navigation Systems** Every day, millions of users interact with digital environments—maps, websites, apps—where smooth, accurate navigation determines how easy it is to reach a destination or understand content. At the core of these systems lies a fundamental geometric principle: finding the closest point on a line to a given point. More than a math concept, this problem is essential in designing accessible interfaces that guide users confidently and independently. Recent data shows growing attention across the United States on digital inclusion and user-centered design, reflecting broader cultural and policy shifts toward equity in technology. As voice interfaces, screen readers, and assistive devices become standard, the precise geometry of proximity defines how well these tools interpret spatial relationships in digital spaces. This problem is no longer hidden behind code—it directly shapes user experience, independence, and inclusion for millions. ---
