Challenges in Setting Interactive Classroom (Virtual Class Rooms)

17th October 2013

What is Virtual Classroom?

• Virtual classroom is a replica of the local class room teaching where

in the students at remote locations will get the same feel and experience as if they are in the same classroom.

• Teacher will be able to use all conventional teaching tools and

continue to teach the way he does.

• Students can ask questions and interact with the teacher as if he is in

the local classroom

Options available for an Interactive Classroom / Virtual Class Room

• Video conferencing setup
• Tele-presence based system
• Room / Group Videoconferencing Systems
• PC based solutions / Software based Solutions

What is expected in a Interactive Class Room

• Clear View of teacher to students
• Teacher shall see Students / participants
• Teacher shall be able use conventional teaching tools
• Teacher shall be able to show computer screens
• Teacher is able to show objects
• Interaction with students
• If required, quick test on topic
• Good learning experience

Concerns while choosing a Technology

• Network availability
• Bandwidth available
• No of students expected in a class
• Dedicated / General Purpose Setup
• Modes of Participation
• Scope of expansion (Scalability)

Gadgets / Equipments required for an Interactive Class Room

• Display systems
• Cameras
• Microphones & Speaker system
• Visualizes / Document Cameras
• Interface to Computer systems
• Interactive writing pad/panels
• User Interface for ease of operations

Setup for Interactive Class Rooms

• Dedicated Teaching stations
• Dedicated Learning Class Rooms
• General Purpose Class Rooms

NATIONAL INFORMATICS CENTRE

• Resolution: Standard Definition or High Definition?

– SD (352x288 to 704x576 pixels) 30 fps – HD720p (1280x720 pixels) 30/60 fps – HD1080p (1920x1080 pixels) 30/60fps

• Bandwidth / Date rates:

128 kbps to 6 Mbps

• Content Resolution :

XGA to HD1080p

• Content frame rate :

1 to 30 fps

• Hardware / SW Systems
• AV Accessories
• Management

IIT Madras  IIT Hyderabad IIT Bombay  IIT Gandhinagar IIT Guwahati  IIT Patna

NIC/NICSI

• Each of six IITs has been provided with

– HD VC system with 2 cameras and 2 mics. – 40” HD LCD TV – 2 nos. – 2500 Lumens Projector – White board Digital Converter – A Laptop

• HD Multi Conferencing Unit installed at

(Central location) NIC Delhi

Details of Equipment supplied in Pilot Virtual Class Rooms

NIC/NICSI

• Operations were largely manual
• Picking up of Student’s audio in

large class rooms was a problem.

• Sharing of the written

documents/3D-objects was not possible

• Display size was small
• The Equipments have not been

permanently fixed in the class rooms

• No special site preparation was done

in the Class rooms w.r.to lighting, layouts, acoustics etc.

THE PROJECT

CREATION OF VIRTUAL CLASSROOMS AT IITS OVER NKN

• The project required the Creation of High Definition (HD)

Video Conferencing based Virtual Class Rooms (VCR) at 15 IITs over NKN

• As per the project at each of the IIT, 3 Virtual Class Rooms will

be set up totalling 45 Virtual Class Rooms .

• A total of 38 VCR are being created at 15 IITs
• NIC office at Delhi, Hyderabad, Bhubaneswar, Pune and

Guwahati were also facilitated with similar facility.

• Later the project was extended to creation of additional 23

VCRs at IISC, NITs, IISERs, CMI etc.

• A total of 66 Virtual Classrooms (VCRs) were created under

this project.

MODES OF VCR

Three modes of operations of VCR

• LOCAL CLASS
• DISTANCE TEACHING
• DISTANCE LEARNING

IIT Delhi (VCR)

IIT Indore IIT Bhubneshwar

Desktop (PC) based video conferencing

Video Conferencing from any PC/Laptop/Desktop equipped web cam, microphone & speakers (HD).

• Based on a New Standard: Scalable Video

Coding (SVC)

• Reaches any desktop or laptop over LAN,

WAN, Internet

• Point to Point
• Multi-point
• Seamless integration with standard video

conferencing end points
