Remotely Activated Virtual Laboratory An e-Learning Tool

Abstract

Colleges are usually equipped with the laboratory equipment required for the prescribed experiments. However, many theoretical concepts require practical demonstration (with sophisticated equipment) for better understanding. These equipment may not be available in colleges, due to which, teaching faculties face difficulty in demonstrating them. In order to overcome this situation, an attempt has been made to develop a system which provides an interface to the user through which sophisticated equipment situated at a remote location can be easily accessed via any computing device. This work emphasizes on Publisher-Subscriber pattern, Subscriber can be any computing system connected to the internet and the Publisher will be a system with LabVIEW to which the lab equipment will be connected via National Instruments Data Acquisition Module (DAQ). For communication between Publisher and Subscriber, an add-on called Smartphone and Cross-Platform Communication Tool (SCCT) has been used.
