VR-AR-QR: NEXT-GEN TECHNOLOGY

Well this is a very long and detailed topic but I'll try my best to simplify it for you people, have a good time reading and gaining knowledge from it

With images and things that seem genuine, a virtual reality (VR) environment gives the user the impression that they are completely engrossed in their surroundings. A virtual reality headset, helmet, or other equipment is used to see this world. A VR headset is used to create this sense of presence; you may borrow one from the OISE Library. Oculus Rift, Samsung Gear VR, HTC Vive, Google Daydream View, and Google Cardboard are further prominent VR headsets.  These headsets block out the outside world and provide visuals to each eye, enabling depth perception. In order to link the virtual environment to what the user is experiencing, this technology is then backed with head and body tracking. Virtual reality immerses the user in an alternate reality using VR headsets or closed head-mounted displays (HMDS).

AUGMENTED REALITY

The real-time integration of digital information with the surroundings of the user is known as augmented reality (AR). Users of augmented reality (AR) encounter a real-world environment with created perceptual information superimposed on top of it, as opposed to virtual reality (VR), which produces a completely fabricated environment.

It also increases our presence via "augmenting" reality by adding digital things and digital object overlays to our already existent world. 

MIXED OR MERGED REALITY

Holographic lenses are used in mixed reality to combine virtual and augmented reality, allowing for the interaction of virtual and real-world items.

360-DEGREE

It employs 360-degree cameras to piece together various pictures to generate 360-degree panoramic photos or films. 

Students may explore, experience, and immerse themselves in virtual worlds via VR, which goes beyond simply engaging them. Virtual reality may be utilized in the classroom in one of two ways: either a student can explore a virtual environment using a computer, keyboard, and mouse, or they can use an input device, such a controller or a virtual reality headset. The latter configuration uses helmet mounted displays (HMD) to completely immerse students. Any topic may be covered with this tool, which also allows teachers a chance to connect with a range of learning methods and explore new ideas with students. For instance, children can explore a rainforest and learn about various plants and animals. The technology also gives designers and programmers a lot of flexibility.

QR CODES

Well QR Is a very different technology apart from AR, VR and those stuff. You can simply do whatever you want with QR.  Do you want to share a video? Use QR. Do you want to share a link? QR is here at your service. I am going to leave you 2 videos about QR, the math behind it and history of it.

Anyways as a bonus, here is a QR code I made. Be sure to test it out :)

Go ahead, scan it.

I mean, what could go wrong, right?
