Video Replacement with Audio Plus Kinect-Based Gestures for Qur'an E-Learning to Reduce Network Traffic

摘要

Kinect is a motion sensing device by Microsoft that can be used for many different purposes.We have explored it's usage in e-learning by introducing it for Qur'an e-learning. This service can be availed by both instructors and students through our online platform of Aalims. It is further divided into two modules. One is implemented for instructor where it conducts the lecture in front of Kinect, which is used for sensing gestures of instructor. These gestures along with voice are then broadcasted to all connected students using peer-topeer connection of WebRTC. Other module is at the students' end that is based on virtual board with Qur'an verses having some highlighted text. Instructor can remotely control highlighted text in front of student, just through his gestures and students only need to have WebRTC enabled browser to attend the lecture. However, instructor needs to have Kinect device installed for gesture recognition. Alternatively, instructor can also use keyboard navigational keys to control the highlighted text. We have also implemented both techniques of audio/video broadcast and audio/gestures broadcast for Qur'an e-learning and experiments proved that replacement of audio/video with audio/gestures consumes less network traffic. Hence we have replaced video streaming with audio plus gestures.
