LOCATIONBASED BIDIRECTIONAL Q＆A AND REALTIME AUDIENCE RESPONSE ACQUISITION AND ALERTING SYSTEM

摘要

PURPOSE: A system for collecting and notifying learner reactions in real time and bidirectional questions and answers based on location is provided to implement real time location recognition based on rapid and accurate location recognition technology in a mobile sensor network including a mobile terminal. CONSTITUTION: A second mobile terminal(140) performs bidirectional communication with a plurality of first mobile terminals(130). A gateway(110) automatically authenticates the first and the second mobile terminals. The gateway relays the bidirectional communication between the first and the second mobile terminals. The gateway provides learning data or a web server for learning to the first and the second mobile terminals in real time by the request of the second mobile terminal.
