Web Based E-learning Tool for Visualization and Analysis of 3D Motion Capture Data

In this paper, we propose an e-learning tool for visualization and manipulation of 3D data on a web platform. The data is streamed in real time from an optical motion capture system Qualisys consisting of eight infrared cameras and Qualisys Track Manager (QTM) software. A WebSocket protocol and WebGL application programming interface (API) are used to visualize and to interact with the data in a browser. The tool represents a web-based extension of QTM software providing also additional features and new possibilities to manipulate and analyze the data. We report also on a user study in which we evaluated the web based application and compared it with the original desktop-based application. The proposed application proved to be fast, effective and intuitive and can be used as an e-learning tool for demonstrating and teaching techniques for visualization and analysis of motion
