Virtual Reality ( vr) and Augmented Reality (ar)


Virtual Reality (VR) and Augmented Reality (AR) are two distinct technologies that have gained significant popularity in recent years. While they both fall under the umbrella of immersive technologies, they offer unique experiences and differ in how they present and interact with virtual elements in the real world. In this article we will tell you about VR and AR in detail, exploring what they are, how they work, and their key differences.

Virtual reality (vr):

Virtual reality is a term used to describe a technology that totally replaces users' real-world surroundings with a computer simulation. The goal of virtual reality (VR) is to give people the impression that they are physically present in the virtual environment. Virtual reality (VR) is built on the idea of "presence," which describes the sensation of being somewhere other than where you are physically.

To experience VR, users typically wear a VR headset, also known as head-mounted displays (HMDs).These headsets come equipped with screens that are positioned in front of the user's eyes, effectively blocking out the real world. The screens display a stereoscopic view, presenting a slightly different image to each eye, which creates a sense of depth and enhances the illusion of being in a three-dimensional space.

Head tracking is a critical component of VR technology. Inside the headset, there are sensors that track the user's head movements, such as rotation and position. This tracking data is then used to update the virtual view in real-time, ensuring that the user's perspective matches their physical movements. As users turn their heads or move within the virtual environment, the view inside the headset adjusts accordingly, creating a seamless and immersive experience
Interaction in VR is facilitated through various input devices, such as handheld controllers or motion sensors. 
These devices allow users to interact with virtual objects, navigate within the virtual space, and perform actions within the virtual environment. For example, users can use their hand controllers to pick up objects

Augmented Reality (AR):


In compared to virtual reality, augmented reality adds virtual features to the user's current surroundings rather than replacing it. By adding more digital information and content that is smoothly integrated into the user's vision, augmented reality (AR) improves the actual world. Due to its potential to combine the digital and physical worlds in a variety of useful and enjoyable applications, augmented reality technology has attracted a lot of attention.

Through gadgets like smartphones, tablets, smart glasses, or heads-up displays (HUDs), users can access AR experiences. These gadgets use their in-built cameras to capture the real-time perspective of the outside world. The software algorithms that process the collected video or picture feed then analyse and comprehend the scene, detecting objects, surfaces, and other crucial details.

The user's vision is aligned with the real-world objects and surfaces after the virtual content is projected onto the real-world picture and analysed. Depending on the particular AR application, this virtual material may take the shape of pictures, movies, 3D models, text, or interactive features. The virtual items are properly scaled and positioned to match the user's actual environment.

In compared to VR, which relies on headset that hide the outside world, AR enables users to stay aware of their surroundings. 
Users can view and engage with both the real and virtual worlds at once because the virtual parts are displayed in a way that makes them seem transparent or semi-transparent.Because of this quality, AR is particularly well suited for a variety of practical applications.
