The development of online labs includes the study and use of mathematical techniques to demonstrate the various complex functions in diverse areas of science. The labs make use of cutting edge simulation technology to create real world lab environments. Thorough study and research is done by research personnel for better understanding of the experimental procedures. Real lab scenarios are captured through live demonstration of the experiment so as to assimilate information on the procedures and lab equipment. Visualisation and development of the graphical symbols are done based on realistic situations and compared with the respective real equipment. Simulations are made interactive using various authoring tools thus recreating and simulating a real lab environment.
