MOBILE VIRTUAL REALITY

SERVICE

LIJO MATHEW

REG.NO:89200327ECE,S6



INTRODUCTION • A mobile virtual reality service (VRS) will make the

presence and presentation of the sounds and sights of an

actual physical environment virtually available everywhere

in real time• VRS is the conversion of a physical system into its digital

representation in a 3D multimedia format.

• multimedia environment to its virtual presence everywhere

in real time .

• VRS do not allow user control in viewing 3D environment’s

& generally limited to viewing images on monitor in 2D



PROBLEM STATEMENT

• From a users perspective, the VRS is defined as the experience ofviewing an object in its 3D environment and sensing its sound with itsnatural and real-world quality

• A virtual movie theaters where a user can view movies with the same

feel as being in a movie theater.

• A virtual conference session depicting to every participant thepresences of others in a virtual conference room with projectorscreen, drawing board, and so on

• The VRS will include both terminal and personal mobility. It could be aset up in a limousine, hotel, airport, home or office



A schematic view of VRSfunctional Architecture



SOLUTIONS The VRS realization scheme is built upon the

development and availability of the followingentities:

• Actual physical environment (APE)

• VRS user equipment (VUE)

• VRS access system (VAS) and

• VRS core system (VCS).



VRS episode setup information flow diagram.



VRS EPISODE SETUP SIGNALINGINFORMATION FLOWS

• Initiating the request for establishing a VRS episode

• Recoganising the request for establishing a VRSepisode

• Sends n information query to VUE• Recoganising the request for establishing a VRS

episode

• Using information on the VUE’s VRSinformation

• VRS have been identified AND\OR alerted• SVECE forward the episode response

• All necessary notification have been received



VRS EPISODE SET UP



GATEWAY ENTITY

• The gate way entity is a bountry functionentity with each VCS .it is the connectionpoint of all VCES in a VCS network from

one side & the GWE of another VCSfrome the other side.



VRS IMPLIMENTATIONSCENARIO

• This section presents an example of VRSarchitecture ,a configuration scenario forsingle VUE &multiple APES participating

in a VRS episode



DISADVANTAGES

• Currently the availability of VRS is limited tofixed applications such as entertainment,machines & flight simulator

•Lack of VRS capable user terminal equipment

• Inadequate data transmission rates over the air

• Absence of efficient and suitable signaling 7
