3. Traditional Laboratory
 Advantages
 Physical access to real equipments
 Generate real data
 Face to face interaction with teacher
 Support from technicians, scientific officers etc.
 Disadvantages
 Costly to establish
 Pre-scheduled lab time table
 Require more number of trained technicians
 High recurring expenses and maintenance charges

4. Animated Laboratory
 Advantages
 Effective visualization of experiments
 Explanation / step to step guide of experiments
 Easily accessible
 No ethical issues
 Disadvantages
 Only visual presentation for users
 Variable can’t be changed to desired values
 Only idealistic results

5. Simulation Laboratory
 Advantages
 More interactive
 User can change the variable to desired values
 Realistic results
 Scope to analyze the critical mistakes generally happened in
real laboratory
 Repeatability
 Disadvantages
 One-to-one instruction from teachers / support from
technician is missing
 Least scope for out of box experimentation
 No access to real time equipments

6. Remote Triggered Laboratory
 Advantages
 Real time access to costly equipments
 Repeatability
 Low instrumental damage
 Cost sharing
 Generate real time data and realistic results
 Disadvantages
 Network related issue
 Experiments could be performed in slots / on-demand only
 Almost no scalability

Virtual Laboratory: To augment the learning in science &
engineering subjects experiments can be performed remotely
through the web-based platforms using the internet.

8. Virtual Labs: A Project of MHRD
 Any time, any where (24x7) free access across the globe
through Web-based platform
 Web link : http://www.vlab.co.in/
 Presently 150 labs and 1500 experiments
 Coverage of major subjects of science & engineering
including communication skills
 Contribution by best institutes of the country
 Invitation for more contribution by educational institutes is
open
 Support / popularization through workshop and web-based
solutions

13. Reality versus Scalability
.

14. Important Features
 Learn at your own pace
 Practical Integrated Learning
 Supported by theory and laboratory manual
 Self –Evaluation
 Animation / videos of real experimental set-up
 Freedom to make mistake i.e. freedom of experimentation
in experiments

15. Requirements to Run Virtual Labs
 System configuration required for running Virtual
Labs:
 Browser: Chrome, Firefox, Internet explorer
 Plugins: Flash Player, Java 1.6 version, and Iced Tea
 JavaScript should be enabled on the browser
 No pop-up blockers
 Internet connection (2-4 MBPS)
 If firewall, the communication ports to facilitate VLab
network traffic should be open. Specifically ports 3306, 5900,
5902, and 8700 need to be opened.

16. Working with Virtual Labs
 Simulation Labs:
 Registration may or may not required
 Can be used by any number of students at any time
 Remote Triggered Labs:
 Registration is required
 After registration receive the user ID and password for slot
booking through e-mail
 After Registration book the slot from available slots
