Enhancing the Viewing Experience of Academic Live Streams with font-size-controller

Abstract

Academic live streaming has emerged as a pivotal medium for knowledge dissemination, academic exchange, and remote education in the digital era. However, suboptimal text readability in the code editing interface during live streams often impairs the audience's comprehension and engagement. This paper introduces font-size-controller, an open-source Visual Studio Code (VSCode) extension designed to dynamically adjust font sizes in the editor. We demonstrate how this tool addresses the core issue of text legibility in academic live streams, thereby significantly enhancing the overall viewing experience for audiences with diverse needs, ranging from live lecture attendees to remote code reviewers. The technical implementation, application scenarios, and empirical benefits of font-size-controller in academic live streaming contexts are discussed, along with its potential for broader adoption in educational technology.
