INFORMATION COMMUNICATION TECHNOLOGY

MEANING

v   Virtual reality (VR) refers to a computer-generated simulation in which a person can interact within an artificial three-dimensional environment using electronic devices, such as special goggles with a screen or gloves  fitted with sensors.

v  In this simulated artificial environment, the user is able to have a realistic-feeling experience

v It has many types in different fields. Let see in this presentation.

TYPES OF VIRTUAL REALITY

NON-IMMERSIVE SCREEN BASED VIRTUAL REALITY

§  Non-immersive VR is a type of the virtual reality technology that provides users with a computer-generated environment without a feeling of being immersed in the virtual world.

§  The main characteristic of a non-immersive VR system is that users can keep control over physical surrounding while being aware of what’s going on around them: sounds, visuals, and haptics.

§  Non-immersive virtual reality systems rely on a computer or video game console, display, and input devices like keyboards, mice, and controllers. 

          Examples :

              Non immersive designing tools are sketches, models , CAD etc

IMMERSIVE LEVELS

SEMI- IMMERSIVE VIRTUAL REALITY

q Unlike these technologies, semi-immersive VR offers users a mix of real and virtual interactive elements.

q At its most basic, semi-immersive VR is one of the oldest kinds of this technology, but today companies are applying it differently.

q 4-D movies may be the traditional use of semi-immersive VR, but now the technology is primarily used for education.

q Flight simulators involving a moving cockpit and simulated environment on screens allow pilots to train without the risks of flying a real aircraft.

q As VR technology improves, developers can produce similar systems for other complicated tasks or professions.

          Example:

                   Flight simulator ,CAVE system etc..

FULLY IMMERSIVE VIRTUAL REALITY

Ø Fully-immersive virtual reality is a digital technology that allows users to experience artificial environments as the real world.

Ø In other words, users perceive virtual computer-generated surrounding using visuals, auditory, and haptics.

Ø The main destination of this technology is to make it impossible for users to recognize they’re in a simulation rather than a real-world environment.

Ø The virtual reality term is often used as a means of the fully-immersive VR.

AUGMENTED VIRTUAL  REALITY

•      AR applications display computer-generated items over real-time images of physical environments.

•       Some consider AR to be a separate technology from VR, but on a technical level, it falls under the umbrella of virtual reality. 

•      AR shows a lot of promise for several industries. Online retailers can use it to project to-scale 3-D images of products onto the user’s home.

•      AR goggles can help workers like technicians and plumbers by displaying instructions in the corner of their vision. Similar applications can help teachers make lessons more immersive for students.

COLLABORATIVE VIRTUAL REALITY

•      Collaborative VR can be as simple as a virtual conference room or as complex as an interactive 3D blueprint that engineers discuss and edit at the same time.

•       Collaborative VR takes video conferencing programs like Skype to the next level. 

•      This form of VR projects the same virtual environment to several users at once, no matter how far apart they may be.

•      As a result, they can share ideas and work together on projects. 

MANUFACTURING REALITY LEVEL

•      One of the industries with the most to gain from VR is manufacturing.

•      VR and AR technology can ensure safety and quality at every step of the manufacturing process, from design to inventory management.

•      Workers can use VR to train in simulated conditions before stepping onto the factory floor.

•      With the right tools, they can decrease the risk of injury when they work with the actual machinery.

•      AR overlays help employees spot errors during quality control checks.

•      Similarly, wearable AR tech will allow workers in inventory operations to identify parts and products more quickly than with the naked eye.

MEDICAL VIRTUAL REALITY

•      The field of medicine has a lot to gain from VR. In a business where accuracy and comprehensive approaches to problems are of utmost importance, virtual environments offer significant advantages across the board.

•      The most apparent of these benefits is that doctors and nurses can train in immersive simulations. Medical staff can use VR to practice surgery in a safe environment with real-time feedback.

•      These environments also prepare for any number of unique situations professionals might encounter. VR can create interactive digital models of the human anatomy that leads to a better understanding of different medical conditions.

•      Apart from training, virtual or augmented reality can assist patients in rehabilitation and recovery where traditional methods have fallen short.

VR THERAPY

•      Physical health is not the only area of wellness that VR can improve. Treating patients who have psychological disorders can be a complicated process, but VR applications help psychiatrists and therapists explore previously unviable options.

•      Professionals often treat patients with phobias or related disorders with gradual exposure to the source of the issue — a process called systematic desensitization or exposure therapy.

•      VR allows these patients to undergo exposure therapy in a controllable, safe and private environment, increasing effectiveness and alleviating concerns associated with traditional forms of this therapy. 

MIXED REALITY

•      One of the most recent advances in VR is the concept of mixed reality (MR). MR is similar to AR in that it combines virtual and real elements. Unlike AR, however, the virtual components in MR interact with the real world, leading to an authentic affected VR experience. 

•      Using technology like the Microsoft HoloLens, people can use MR to interact with 3D holograms in comfortable physical environments like their living rooms.

•      MR creates immersive tours and demonstrations, allowing students to gain a well-rounded understanding of a variety of concepts. Companies can use MR applications to generate unique and engaging team-building exercises for employees. Companies can use MR applications to generate unique and engaging team-building exercises for employees, which is super important for building strong relationships within the team.
