18. Types of Virtual
Reality

19. Types of Virtual Reality
● Enhanced Reality
● Desktop Virtual Reality
● Telepresence
● Immersive Virtual Reality
● QTVR

20. Enhanced Reality
● Enhanced Reality (ER) is an emerging technology that blends the
physical world with digital information in real-time, offering users
an enriched perception of their surroundings. Also known as Mixed
Reality (MR) or Augmented Reality (AR), Enhanced Reality goes
beyond traditional AR by seamlessly integrating virtual elements
into the user's environment, often in a more interactive and
immersive manner.

21. How Enhanced Reality Works
● Sensing Environment: Enhanced Reality systems utilize various sensors such as
cameras, depth sensors, GPS, and inertial measurement units (IMUs) to perceive the
physical world and track the user's movements accurately.
● Processing: The data collected from sensors are processed in real-time by powerful
computing devices like smartphones, tablets, or dedicated headsets. Advanced
algorithms are employed to understand the user's context and spatially map virtual
objects onto the physical environment.
● Overlaying Digital Content: Virtual elements, such as 3D models, text, images, or
animations, are superimposed onto the user's view of the real world. These digital
overlays are precisely aligned with the physical environment, creating a cohesive and
believable user experience.

22. Desktop Virtual Reality
● Desktop Virtual Reality (VR) refers to a subset of virtual reality experiences
that are designed to be utilized primarily with desktop computers or
laptops, often without the need for specialized VR headsets. This form of VR
typically relies on the existing hardware of a desktop system, combined
with compatible software applications and sometimes additional peripherals
like motion controllers or tracking devices. Desktop VR experiences offer a
more accessible and affordable entry point into virtual environments
compared to high-end VR setups that require dedicated headsets and
sensors.

23. Components of Desktop Virtual Reality
● Desktop or Laptop Computer: The core component of desktop VR is a standard
desktop computer or laptop. These systems serve as the computing platform for
running VR applications and rendering virtual environments. While high-performance
hardware can provide a smoother and more immersive experience, many VR
applications are designed to run on mid-range or even lower-end systems.
● VR Software: Desktop VR experiences rely on specialized software applications that
generate and render virtual environments. These applications can range from video
games and simulations to productivity tools and educational content. Some popular VR
software platforms for desktop computers include SteamVR, Oculus Rift, and Windows
Mixed Reality.
● Head-Mounted Displays (Optional): While desktop VR experiences can be enjoyed
without dedicated VR headsets

24. Telepresence
● Telepresence refers to a technology that allows a person to feel as if they are present,
or "telepresent," at a location other than their physical one. It aims to provide a sense
of being physically present in a remote environment by using a combination of audio,
video, and other sensory inputs. Telepresence systems are often used in situations
where physical presence is either impractical or impossible, such as remote meetings,
virtual tours, or telemedicine.

25. Components of Telepresence
● Audiovisual Equipment: The core components of a telepresence system include
cameras, microphones, speakers, and displays. High-definition cameras capture live
video of the remote environment, while microphones capture audio. Displays present a
live feed of the remote environment, allowing participants to see and hear what is
happening in real-time.
● Network Infrastructure: Telepresence systems rely on network infrastructure, such as
the internet or dedicated communication networks, to transmit audio and video data
between locations. High-speed and reliable network connections are essential for
maintaining the quality and responsiveness of the telepresence experience.
● Control Interfaces: Users interact with telepresence systems through control
interfaces, such as touchscreen panels, keyboards, or remote controls. These
interfaces allow users to initiate calls, adjust audiovisual settings, and control camera
movements remotely.

26. Immersive Virtual Reality
● Immersive Virtual Reality (VR) refers to a form of virtual reality
technology that aims to fully immerse users in realistic and
interactive virtual environments, often using specialized VR
headsets and motion tracking systems. Unlike traditional forms of
media consumption, immersive VR transports users to digital
worlds where they can explore, interact, and experience sensory
feedback as if they were physically present in the virtual
environment. This level of immersion is achieved through a
combination of advanced hardware, software, and sensory input
devices.

27. Components of Immersive Virtual Reality
● VR Headsets: Immersive VR experiences typically rely on specialized VR headsets
equipped with high-resolution displays, lenses, and motion sensors. These headsets
immerse users in virtual environments by rendering stereoscopic 3D images that
create a sense of depth and presence. VR headsets may also feature integrated audio
systems, eye-tracking technology, and adjustable straps for comfort.
● Motion Tracking Systems: To enhance immersion, immersive VR systems utilize motion
tracking technology to monitor the user's movements and translate them into the
virtual environment in real-time. This allows users to walk, gesture, and interact with
objects as they would in the physical world. Motion tracking systems may employ
external sensors, cameras, or inside-out tracking sensors embedded in the VR
headset.

28. QTVR
● QuickTime Virtual Reality (QTVR) is a type of virtual reality technology
developed by Apple Inc. in the mid-1990s. QTVR enables users to create and
view interactive panoramic images and 360-degree virtual tours using the
QuickTime multimedia framework. It was one of the earliest methods for
delivering immersive virtual reality experiences on personal computers.

29. Components of QTVR
● Panoramic Images: QTVR allows users to create panoramic images by stitching
together multiple photographs or rendering images from 3D modeling software.
Panoramic images capture a 360-degree view of a scene, providing users with the
ability to look in any direction within the virtual environment.
● Viewer Software: QTVR content is viewed using specialized viewer software that is
compatible with the QuickTime multimedia framework. The viewer software enables
users to interact with panoramic images by panning, tilting, and zooming to explore
different perspectives of the virtual environment.
● Interactivity: QTVR supports interactive features such as hotspots, which are clickable
areas within the panoramic image that trigger actions or display additional information
when selected by the user. Hotspots can be used to navigate between different
panoramic views, access multimedia content, or provide contextual information about
objects within the virtual environment.

30. Virtual reality applications
can be divided into

31. ● Entertainment and Gaming: This category includes immersive gaming
experiences, virtual reality arcades, and interactive entertainment content
designed for virtual reality platforms. VR games range from action-packed
adventures to immersive simulations, providing users with engaging and
immersive entertainment experiences.
● Education and Training: Virtual reality is increasingly being used in
education and training to create immersive learning experiences,
simulations, and virtual laboratories. VR-based educational content covers
diverse subjects, including science, history, art, and vocational skills, and is
used in schools, universities, and professional training programs.

32. ● Healthcare and Therapy: Virtual reality has applications in healthcare for medical
training, patient education, and therapeutic interventions. VR simulations enable
medical professionals to practice surgical procedures, diagnose medical conditions,
and conduct virtual surgeries in a safe and controlled environment. VR therapy
programs are used to treat phobias, anxiety disorders, and post-traumatic stress
disorder (PTSD).
● Architecture and Design: Virtual reality technology is used in architecture and design
industries for architectural visualization, interior design, and virtual prototyping. VR
enables architects, designers, and clients to visualize buildings, explore spaces, and
provide feedback on design concepts in a realistic and immersive manner.
● Tourism and Cultural Heritage: Virtual reality applications in tourism and cultural
heritage include virtual tours, interactive exhibits, and digital recreations of historical
sites, museums, and cultural landmarks. VR tourism enables users to explore
destinations, discover landmarks, and experience immersive travel experiences without
leaving their homes.

33. ● Remote Collaboration and Communication: Virtual reality technology enables remote
collaboration and communication in virtual environments, allowing users to meet,
interact, and work together regardless of their physical location. VR-based
collaboration platforms offer features such as avatars, spatial audio, and shared
whiteboards, enabling remote teams to collaborate effectively across distances.
● Training and Simulation: Virtual reality is used for training and simulation in various
industries, including aviation, military, and manufacturing. VR simulations provide
realistic scenarios, hands-on practice, and feedback mechanisms that enhance
learning outcomes and improve performance in real-world tasks.
● Art and Creativity: Virtual reality technology is used by artists, designers, and creatives
to explore new forms of expression and create immersive artworks, virtual installations,
and interactive experiences. VR art applications enable users to paint, sculpt, and
manipulate virtual objects in three-dimensional space, blurring the boundaries
between traditional art forms and digital media.

34. Advantages
● Although the disadvantages of VR are numerous, so are the advantages. Many
different fields can use VR as a way to train students without actually putting anyone
in harm's way. This includes the fields of medicine, law enforcement, architecture and
aviation. VR also helps those that can't get out of the house experience a much fuller
life. These patients can explore the world through virtual environments like Second
Life, a VR community on the Internet, exploring virtual cities as well as more fanciful
environments like J.R.R. Tolkien's Middle Earth. VR also helps patients recover from
stroke and other injuries. Doctors are using VR to help reteach muscle movement such
as walking and grabbing as well as smaller physical movements such as pointing. The
doctors use the malleable computerized environments to increase or decrease the
motion needed to grab or move an object. This also helps record exactly how quickly a
patient is learning and recovering.

35. Disadvantages
● The disadvantages of VR are numerous. The hardware needed to create a fully
immersed VR experience is still cost prohibitive. The total cost of the machinery to
create a VR system is still the same price as a new car, around $20,000. The
technology for such an experience is still new and experimental. VR is becoming much
more commonplace but programmers are still grappling with how to interact with
virtual environments. The idea of escapism is common place among those that use VR
environments and people often live in the virtual world instead of dealing with the real
one. This happens even in the low quality and fairly hard to use VR environments that
are online right now. One worry is that as VR environments become much higher
quality and immersive, they will become attractive to those wishing to escape real life.
Another concern is VR training. Training with a VR environment does not have the same
consequences as training and working in the real world. This means that even if
someone does well with simulated tasks in a VR environment, that person might not do
well in the real world.
