A bandwidth saving mobile application for e-learning

Abstract

In this paper, we proposed a bandwidth saving e-learning system for mobile learners who wish to save their bandwidth. In the meantime we provided a more user-friendly and comprehensive administration tool for teachers to prepare and deliver course materials (in form of presentation slides) more efficiently and easily. The teachers can create their presentation slides through the back-end user interface by a few clicks, or upload existing MS Power Point slides onto the system. The slides can be converted into smaller sized files (e.g. compressed image files) that saves the bandwidth of the mobile device of the user. In addition, teachers may record their audio narration in order to give a clearer explanation to the contents. Furthermore, the teacher can monitor the students’ learning progress and their performances through the system generated analysis reports. User studies have been conducted to verify whether the app interface is user-friendly for the learners. We have collaborated with Hong Yip (a property management company) and deliver online courses to the front-line workers on trial basis.
