Unified 3-D Interactive Human-Centered System for Online Experimentation : Current Deployment and Future Perspectives

Online experimentation systems that support remote and/or virtual experiments in an Internet-based environment play an important role in skill-enhanced online learning, especially in the field of engineering. This article explores a human-centered online system with a unified architecture that covers the entire process of control engineering experimentation. The control and security-oriented design are presented and the human-centered design including the HTML5-based web application and the configurable graphical user interface is also introduced. Interactive features such as tuning parameters and 3-D animations and interactions are integrated into the system. Enhanced 3-D effects such as anaglyph 3-D and parallax 3-D are also provided. Thus, users can experience different types of 3-D effects on experiment equipment or in a 3-D virtual world while conducting experiments. Details of an application example with a dual tank system are also explored to verify the performance of the proposed system.
