Synchronous Mobile Learning System to Cope with Slow Network Connection

초록

The network connection of a mobile device can get slow temporarily due to its high mobility. This could make synchronous mobile learning system unable to receive the video and audio from the server, thereby making students find difficulty understanding the real-time lecture on their mobile devices. Thus, we propose a synchronous mobile learning system that enables students to follow the ongoing lecture in such temporary slow network connection. The system allows students to watch an instructor and slide with annotation in real time. The students can send questions to an instructor and discuss together in text. To make students not to miss the lecture while the video and audio can't be delivered due to low-speed network connection, live speech text is supported by converting the instructor's speech to text in real time.
