History of VR

It began in the 1960s when smart people started thinking about making computer worlds that feel real. But it wasn’t until the 1990s that Virtual Reality started getting attention.

There were VR headsets and games at the time, but they were big and not very popular. People liked the idea of virtual reality, but it still needed improvement.

In the early 2010s, VR started to come back quickly. Companies like Oculus (which Facebook bought) started making excellent VR headsets. These new headsets could track your movements and make you feel like you were in a fake world.

As technology got better, VR became more popular. It’s not just for games now – people use VR for all sorts of things, like teaching pilots, helping doctors, and even taking trips without leaving their homes.

Virtual Reality technology has improved a lot over time. It started with basic systems and got better with more immersive experiences.

At first, VR was big and costly, making it hard for most people to use. But now, thanks to better technology, VR is cheaper and easier for everyone to enjoy.

How does VR work?

When you put on a VR headset, you see special screens that display a simulated but highly realistic world. As you move your head, the screen moves accordingly, so it feels like you’re immersed in this new virtual environment.

VR also manipulates your hearing to enhance the experience. Sounds come at you from different directions, just like they do in the real world. This makes the experience more concrete and multi-dimensional.

Sensors and cameras monitor your movements. So, when you move your body in the real world, your perspective changes to the virtual world. This is important for VR games and simulations where you want to be able to move around and interact with objects.

Some virtual reality systems also have haptic devices to make you feel tactile sensations. For example, if you approach something in the VR world, you may have a slight vibration in your hands, as if you were actually handling it.

1. Non-immersive VR

Non-immersive VR uses a computer screen or handheld device to display a virtual environment. Users can interact with the virtual world using input devices such as a mouse or keyboard.

2. Semi-immersive VR

Semi-immersive VR provides a more immersive experience by using a larger display or projection screen. In this, users can move around a specified area and interact with the virtual environment using peripherals such as joysticks or motion controllers.

3. Fully Immersive VR

Fully Immersive VR aims to create a completely unbelievable experience using head-mounted displays (HMDs) like Oculus Rift or HTC Vive. These HMDs provide a 360-degree view of the virtual world, allowing users to feel fully present in the digital environment.

4. Augmented Reality (AR)

Augmented Reality (AR) is closely related to VR, and it combines virtual elements with the real world. AR overlays computer-generated content onto the user’s view of the physical world, usually through a smartphone or smart glasses. This technology enhances the user’s perception of reality by adding digital elements such as text, images, or 3D models.

5. Mixed Reality (MR)

MR combines elements of both VR and AR to create a hybrid experience. It involves the integration of virtual objects into the real world so that they can interact with the physical environment. Microsoft’s HoloLens is an example of MR technology.

6. 360-degree VR

The 360-degree VR utilizes omnidirectional cameras to capture a 360-degree view of a real or virtual environment. Users can then view these videos or images using VR devices, allowing them to look in any direction and feel present in the recorded scene.

7. Room-Scale VR

Room-scale VR refers to the ability to move within a designated area while wearing an HMD physically. This type of Virtual Reality system incorporates sensors or cameras to track the user’s position and adjust the virtual environment accordingly, creating a more immersive and interactive experience.

8. Mobile VR

Mobile VR applications are experienced using a smartphone or a standalone virtual reality headset. These VR uses the phone’s screen and sensors, providing an accessible and portable VR experience.

9. Social VR

Social VR allows multiple users to interact with each other in a shared virtual space, often represented by avatars.
