Virtual reality on web

Term breaks are going on and during this period i am researching on Virtual reality on web, what are the impacts of virtual reality on web, what are the things requires for webvr. Virtual reality has becoming very popular now a days. Mozilla, Janus, Chrome these are some companies and browsers are using VR on web. I have researched through these websites and articles based on VR on web. For webvr JavaScript API language is required which supports the VR devices. Virtual Reality Modeling Language(VRMP) is the standard who supports the conveyance of 3D models on the internet. On the other side basically HTML (Hyper Text Markup Language) is the current standard for authoring home pages. The VRML models are based on a polygonal representation and they can be animated, many functions and dynamic behavior can also be adding and can be interactively controlled by any user. Home pages can be changed into “Home spaces” in future which will hyperlinks to other pages or spaces located on server within the WWW. At the center of a large portion of these VR frame works is a PC model that is typically produced utilizing 3D displaying strategies as, bolstered by many CAD/CAM frameworks. The model should be a polygonal representation of all geometry included. I have completed 6000 words so far after this topic. Next i will write about webvr companies.

Top virtual reality companies

Virtual reality is an emerging technology which is famous in all over the world. There are number of companies who is promoting Virtual reality worldwide. Every day these companies coming with new features in the field of virtual reality.  Following are some leading companies in Virtual reality.

  • Samsung Gear VR
  • HTC vive
  • Google
  • Facebook/ Oculus Rift VR
  • Microsoft HoloLens

This week am going to write about the top companies who is using the virtual reality. Every day many companies come with new features and latest inventions in Virtual reality. My task is to research on these companies who is inventing these Virtual Reality headsets.

3 meeting

Today was the meeting with my project supervisor Neil Benson. The meeting schedule is every week on Monday but Neil Benson postponed the meeting to Thursday because he had a project to do. That’s by he postponed our meeting to Thursday. He looked my project and told me that i am going well. We discussed about some issues about project. He suggested me some ideas to make my report more impressive. He also told me that he will ask Clare about my project means what else she want in my report.

2 meeting

Today i had meeting with my project supervisor Neil Benson. I showed him overall work i have done so far. He liked the way i did all the work. He discussed some issues regarding Virtual Reality. He advised me to add some more stuff in this project related to VR. For this week my task is to find more stuff for this project.

Types of virtual reality

This week I am researching on different kinds of Virtual Reality. Nowadays virtual reality has been used as an interactive video game, 3d movies, and television serials and in marketing. It is difficult to groups all virtual reality systems, but we have divided virtual reality system in following categories.

Fully immersive

Non-immersive

Collaborative

Web-based

Augmented reality

Semi-Immersive Projection Systems

Shutter Glasses

These are some kinds of Virtual Reality which I have researched. I will write all these types of Virtual Reality in detail in my project report.

Working of virtual reality

This week I am working on how does Virtual Reality works. Virtual reality is a very exclusive invention but how does it work? What makes us think we are in the real world? This is the main question. To know about how VR works let’s start from basics.

Virtual reality is being used by many companies and websites like Oculus, HTC, Samsung, Sony, YouTube etc all they required is three things personal computer, smartphone, and a headset. In VR process headset is used to show the virtual world, actions, voice etc and smartphone is used to run games. Virtual reality headset contains two LCD displays for both eyes.  Both LCD displays contain lenses for eyes and the pixels all these stuff make a device called goggles. In some cases, these can be adjusted to match the distance between your eyes which varies from person to person. These lenses focus and restructure the picture for each eye and create a stereoscopic 3D image by angling the 2D images to mimic how each of our two eyes views the world ever-so-slightly differently. If you close one eye and trying to see with another eye, then you will come to know the idea behind it. One important way VR headsets can increase immersion is to increase the field of view i.e. how wide the picture is. A 360-degree display would be too expensive and pointless. Most high-end headsets make do with the 110-degree field of view which is wide enough to do the trick.

Oculus is having 90fps fps stands for frames per second, for instance, Sony’s Project Morpheus of 120fps. Virtual reality means feeling things through our comp that don’t really exist.

There are a number of technologies planned to give a different experience of the different world to explore. In Virtual reality, HMD which stands for head mounted display plays an important role which uses a technique named stereoscopy that gives different images to each eye. In oculus rift a single LCD screen which having a color depth of 24 bits per pixel and also having a 1000 hertz head to head reality tracker that decreases potential to improve the overall quality of the images when HMD moves. Each eye lenses gives the presence of deepness and mean the images totally cover the wearer field of vision.

Tracking software built into the HMD means that when the user moves their head, the virtual world moves with them. A built-in three-axis gyroscope, magnetometers (which measure the strength of the Earth’s magnetic field) and accelerometers (to measure how fast the HMD is moving in space) all allow accurate head tracking and therefore the perception that the environment is real.

These three technologies change the images fed to the HMD as the wearer moves around. This sense that the scene they see moves as they do is how VR wiles your brain into thinking you are in a real place. Movement is also a key component of conclusive VR. The Omni from Virtuix is the perfect companion for a VR HMD and controller. The routine works with the user wearing modified stuck shoes. When the shoes make contact with the grooved, low- friction surface of the Omni, the plates within the treadmill move to mimic the walking on a flat surface. Users can even run or jump with their relative position fed back to the computer generating the images shown on the HMD. As users walk unsupported – just as you would in the real world – the illusion of movement through the VR space is assured.
