The document is a project proposal for a remote web air hockey game developed by a team at Chung-Ang University, named 'nullpointexception.' The game allows users to control gameplay using their smart devices while they view the game on web pages, with a focus on real-time communication facilitated by socket.io and a server built on Node.js. The proposal outlines the technology stack, team roles, and a development schedule that includes design, client and server development, testing, and final demonstrations.
