Q1. What is Virtual Reality(VR)?
Virtual Reality(VR) can be considered an Artificial Environment that provides you with a real-life environment and experience. There are many software and techniques available that can create a simulated environment. This is a different experience than the traditional user interface. Using VR, the user will be able to interact with the 3D world. VR experience can be created by altering as many senses as possible to make the VR experience much better and powerful. It allows you to create those things via a computer that does not exist, but you can feel them as they are real.
Q2. What are the 3 elements of virtual reality?
Q3. What is the main purpose of virtual reality?
Q4. What are the benefits of virtual reality?
- Increase knowledge area
- Active experience rather than just passive information
- Helps to understand complex concepts, subjects, or theories
- No distractions while the study
- Boosts students creativity
- Expands learners efficiency to gain knowledge
- Increase Interest in boring subjects like science
- Improve the understanding level of students
- Improve teaching skills in teachers using VR by providing a deep level of knowledge.
- Improving memory power by connecting feelings with education.
- It takes very little time to understand very complex topics.
- Get education as per the book syllabus with its connecting environment and practicals.
- Fun, Virtual tour, and existing game-based education.
- Improve a Student’s Imagination power.
Q5. What is new in Virtual Reality(VR) Technology?
Immersive and innovative digital tools such as 3D learning environments, virtual reality, augmented reality, and mixed reality facilitate experiential learning that allows students to grasp theoretical concepts faster and in greater depth. Immersive learning enhances the learning process by adding content that is interactive and engaging, allowing for experimentation, practice, and learning by doing. This greatly appeals to an insatiable curiosity residing in young learners, and due to the possibility of multiple instances of connecting with key concepts, enables learners to work at their own pace and to their level of proficiency.
Using VR Tech, any learner understands complex scientific concepts with fun and ease, for example, when a student uses Virtual Reality to understand “Respiration System in a human body” the student will understand that while breathing, so many gaseous elements go inside the lungs and how the oxygen is filtered from the other elements and how it will bound with RCB. This RCB containing oxygen penetrates the cell membrane and breaks glucose, to produce water and carbon dioxide. During this process, energy is released, which is captured by the ATP molecule. All these explanations are in 3D & 360° which will help the student to remember it easily and then recall whenever required. The example I have discussed here is just a glimpse of our vast VR content Library.
Virtual Reality is used in education to enhance student engagement with their study. VR creates the real world around us. It can transform the way of education which is provided nowadays. It can be also used in industries, medical, security, military, Anti-terrorism, Traffic accidents awareness, Weather forecasting, etc.
Q6. What are 5 advantages of VR technology?
- Improved learning and performance.
- Making the impossible possible.
- Speeding up the learning process.
- Reducing costs.
- Remote training and accessibility: great for your company, great for the planet.
Q7. What is 3I in virtual reality?
immersion, interaction, imagination and we will also add one more I for the immersive VR system.
Q8. What is Total Immersion in Virtual Reality(VR)?
Total immersion means that the sensory experience feels so real, that we forget it is a virtual-artificial environment and begin to interact with it as we would naturally in the real world. In a virtual reality environment, a completely synthetic world may or may not mimic the properties of a real-world environment. This means that the virtual reality environment may simulate an everyday setting (e.g. walking around the streets of London), or may exceed the bounds of physical reality by creating a world in which the physical laws governing gravity, time and material properties no longer hold (e.g. shooting space aliens on a foreign gravity-less planet).
Q9. What is VRML?
VRML (Virtual Reality Modeling Language) — VRML (pronounced as “
V-R-M-L” or “
ver-mal”) is a modeling language which helps to create platform-independent 3D objects and interactive scenes on a web page. It was first introduced in 1994 at the first World Wide Web conference by Mark Pesce, Tony Parisi, and others. VRML had initially stood for Virtual Reality Markup Language. The VRML files are known as worlds and have “.wrl” extension. A VRML world is built using nodes. Nodes describe the geometry, sound, properties of the world, and more.
Q10. What is Virtual Reality Cloud?
Virtual Reality Cloud is the use of a cloud service provider's infrastructure to render Virtual Reality (VR) code on a remote server before streaming the programming to an end user's virtual reality headset. The goal of VR cloud is to lower the total cost of experiencing VR programming by removing requirements for powerful graphical hardware and compute resources to be installed locally.
Q11. Explain Sensors in VRML language?
One of the crucial components of VR applications is locomotion, which is used for moving the viewpoint of user in virtual environments. Locomotion in VR is expected to have a direct effect on user experience in terms of effort, enjoyment, frustration, motion sickness and presence. To date, many locomotion techniques for VR have been studied. However, these techniques were primarily evaluated in large tracked areas (larger than 16 ft by 16 ft). On the contrary, emerging consumer VR systems typically track within smaller room scales. In this study, eight VR locomotion techniques were investigated in a room-scale tracked area (8 ft by 8 ft).
These eight locomotion techniques are :
point & teleport,
hand flapping and
flying. A user study was performed with 15 participants. Results indicated that point & teleport, joystick and redirected walking were suitable VR locomotion techniques for room scale tracked areas whereas hand flapping and flying were not suitable.
Q13. What are the types of AR?
Q14. What is ARKit and ARCore?
ARKit and ARCore are software development kits (SDKs) released by tech giants Apple and Google. They enable developers to create augmented reality or AR-based apps that are tailored to today's smartphones, and as such, both are vital tools for eCommerce companies.
Q15. What is Unity in AR?
Q16. What is the difference between HTML and VRML?
|It is a markup language.
|It is a modeling language.
|It creates 2D documents.
|It creates 3D worlds.
|HTML is not case-sensitive.
|VRML is case-sensitive.
|All HTML versions are backward compatible.
|No backward compatibility among VRML versions.

|Files have .wrl extension.
Q17. Explain some Applications of Virtual Reality (VR).
Today, virtual reality applications are in high demand. Many companies are using this technology to boost their business. Basically, virtual reality deals mainly in the gaming section.
