Virtual Reality for Telecommunication

• Application of VR and Telecommunication
• Telemedicine
• Tele-education
• Tele-training
• Tele-banking
• Tele-work

Virtual Reality for Telecommunication

• VR technology in Telecommunication
• Using VR to manage Broadband Telecommunication
  Networks
• VR user interfaces for broadband network
• Allows network structure information flow to be
  visualized
• So immediately responds through VR reduce error
  
• Act as though in the real world using data
  gloves.

Potential VR for E-Commerce

• Introduction
• Three-dimensional (3-D) multi-user online
  environments constitute a revolution of
  interactivity by creating a compelling online
  experience.
• VE offers e-shoppers the ability study the
  product carefully.
• Provides the e-shoppers confidence that what they
  see is actually what they will get. Give better
  description on product.

11
Potential VR for E-Commerce

• Furniture and Interior Design
• Helps user to create their ideal home interior by
  just a few clicks.
• Provide the user with the actual view of the
  decoration of rooms and also the details of the
  furniture.
• Reduce the effort and cost to make changes.

12
Potential VR for E-Commerce

• Real Estate
• To show the architecture and interior design for
  the house or buildings to attract more buyers
• Buyers may tour around and have information on
  the building regarding size interior design and
  facilities near by facing area and others.
• Save time on going to see the model of house
  which might be too small.

13
Potential VR for E-Commerce

• Travel and Tour
• Offers the high end of interactivity to promote
  the places of interest.
• Provide actual scene of places to understand the
  place
• Able to tour without restriction of time and
  direction
• Given better understanding of location from
  interactive map/ linked panoramas given.

14
Potential VR for E-Commerce

• Virtual Hotels
• Able to promote the hotels by giving virtual tour
  on hotel and let the customer booked the room
  online by online booking system. Its give the
  best convenience to customer consequently
  increase the hotel business.
• Able to tour around for view of the interior
  design.
• Easily have information of facilities and the
  size of the room as actual room.
• Able to compare the price and choose the best

15

• Virtual Product Shop
• extends product familiarity effect motivation
  and decrease product ambiguity leading to
  elevated levels of arousal enhanced shopping
  enjoyment and heightened brand preference.
• provides complete backend interface.

• Conclusion
• 3D E-Commerce is able to provide consumers with a
  new type of mediated experience--virtual
  experience.

Collaborative Virtual Environment and
Collaborative Computing

• Collaborative Computing
• environment setup to allow users to work together
  sharing their ideas and applications remotely
  independent of their location.
• facilitates workgroup computing or better known
  as GroupWare.
• come in shared online whiteboard video
  conferencing audio conferencing and shared
  application.
• take the form of Virtual Reality or Virtual
  Environment Collaborative Virtual Environment

18
Collaborative Virtual Environment and
Collaborative Computing

• Shared Virtual Environment (VE) Systems
• multi-participant environment with the
  presences of graphics networkingand human
  interaction
• Characteristics that motivate the origin of
  shared virtual environment
• Computation power ubiquitous rendering
  capabilities smooth and realistic contents
• Interactive content which provides intelligent
  feedback
• Cyberspace where a single space is occupied by
  millions
• Infrastructure requirements dynamic
  extensibility scalability and composability

19
Collaborative Virtual Environment and
Collaborative Computing

• Architecture for Virtual Environment
• Serverless System (peer-to-peer multicast)
• Each player node broadcast its state directly to
  other player. No central bottleneck or d\single
  point of failure but comes with a price of
  hardship to manage the system.
• Centralized System
• All clients connect to a single server for
  communication.
• Multiple Server System
• VE is divided into regions.
• Coordinated Multiple Servers
• Having a hierarchy of servers to allow tiers of
  filtering. This approach enhances the sharing
  system while at the same time adds to the
  difficulty in coordination

Collaborative Virtual Environment and
Collaborative Computing

• Advantages of the distributed approach that to be
  taken consideration in the current Virtual
  Environment issues
• Robustness user can rejoin the session and be
  updated to its current state.
• Efficient network performance all operations
  and GUI updates are performed locally on all
  endpoints.
• Groupware environment multiple users can use
  different tools simultaneously and can share data
  without compromising security.
• Flexible file sharing users can control access
  to files during a collaborative session.
• Familiarity users can retain their existing
  windowing environment.
• Heterogeneous support allows interoperability
  between cross-platform applications.
