UNIT V –VR APPLICATIONS

INTRODUCTION

• VR is not so much a technology, but more a mode of computer interactions.

• VR is here to stay and will become a natural feature of computer systems.

• VR applications is divided in to

– ENGINEERING

– ENTERTAINMENT

– SCIENCE

– TRAINING

APPLICATIONS

•Military simulators.

• Teleconferencing.

• Telepresence.

• Remote sensing.

• Medical applications.

• Entertainment industry.

• Training, simulators – Flight, cars, military, surgery, etc.

• CAD / prototypes / visualization – Useful when designing many kinds of products –Architecture, oil exploration, Boeing 777 –Marketing

• Entertainment, casinos, games

• In the future, VR may have a big impact on novel user interfaces

ENGINEERING

• 3D CAD systems is used to design everything from shoe to oil rig.

– AERO ENGINE DESIGN

– SUBMARINE DESIGN

– ARCHITECTURE

– HUMAN FACTOR MODELLING

– INDUSTRIAL CONCEPT DESIGN

AERO ENGINE DESIGN

• ProVision 100Vpx systems-Aircarft engine simulation

• CADDS4X –Rolls Royce aero engine maintenance.

SUBMARINE DESIGN

• VSEL-Vickers Ship builiding and Engg Limited-specializes in submarine design and refit planning

ARCHITECTURE

• CAD SYSTEMS-visualization of data related

• VR SYSTEMS

– ILLUMINATION-buildings internal aesthetics

– ACOUSTICS-HRTF

HUMAN FACTOR MODELLING-JACK

• Physical attributes

• Inverse kinematics

• Ergonomics

• Collision Avoidance

INDUSTRIAL CONCEPT DESIGN

ENTERTAINMENT

The entertainment industry is one of the most enthusiastic advocates of virtual reality, most noticeably in games and virtual worlds. But other equally popular areas include:

• Virtual Museums, e.g. interactive exhibitions

• Galleries

• Theatre, e.g. interactive performances

• Virtual theme parks

• Discovery centres

• Many of these areas fall into the category ‘edutainment’ in which the aim is to educate as well as entertain.

SCIENCE• In computational neuro science

• Molecular modeling

• Phobias

• Ultrasound echography

TRAINING- MILITARY

• VR software and display equipment go beyond many standard limitations

• allow users to communicate and cooperate with each other in digital world as well as

• reduce the costs and the number of real exercises needed for military personnel training.

• Presently, computer applications are mostly used to train military pilots and tank crews in safe

• environments. Soldiers step into a physical mockup of the vehicle surrounded with projection

• screens which in the real time generate 3D world around their perception.

• Advanced first response simulators based on Virtual Reality technology gives us

• a significant benefits, such as:

• Repeatability – each mission can be repeated many times, results may be stored, and played to analyze and compare individual behavior.

• Knowledge transfer – years of ground in combat experience may be captured and documented for young soldiers’ training.

• Safe training – the highest risk possible combat scenarios may be simulated to deceive soldiers perception without exposing them to any physical risk of injury.

• Economic factor – soldiers deployment may take place without moving

• expensive military equipment and troops to foreign country or ally training

• ground, ammunition and fuel expenses are eliminated.

• Behavior evaluation – VR allows to detect suspicious behavior and actions of

• individuals in dangerous combat conditions, and their decision making process.
