Types of Virtual Reality
Virtual reality has undergone significant evolution, resulting in various types, each boasting distinct features and applications. Among the most pioneering forms of virtual reality that presently exert substantial influence and promise to shape the future are the following:
1. Non-Immersive Virtual Reality
Non-immersive virtual reality encompasses computer-based simulations where users exert control over characters or activities within the software, yet the environment does not directly engage with them. Alongside desktop computers, powerful laptops equipped for virtual tasks and portable productivity are increasingly sought after by consumers. In response to the growing demand for mobility, manufacturers engineer robust systems packaged in compact forms.
For instance, in gaming scenarios like World of Warcraft, players manipulate characters endowed with distinct movements and attributes. While technically interacting with the virtual environment, users remain secondary to the focal point of the game. All actions and features within the virtual landscape revolve around the characters embedded within it, maintaining a degree of separation from direct user engagement.

However, there is no physical interaction or immersion between it and the virtual world, and the user still remains in the real world while sitting at the computer.
2. Fully Immersive Virtual Reality
In contrast to non-immersive virtual reality, fully immersive virtual reality offers an unparalleled sense of realism within the digital realm. Users are enveloped in a convincing virtual environment, experiencing events as if they were unfolding in real-time. This advanced VR format demands specialized equipment such as helmets, gloves, and sensor-laden body connections, all intricately linked to high-performance computers.
Within the virtual landscape, intricate sensors capture and reflect users' emotions, reactions, and even subtle movements like a blink of an eye, enhancing the sense of immersion. An illustrative example involves being equipped in a confined space with requisite hardware to engage in immersive experiences such as virtual shooter games, where the boundaries between reality and simulation blur seamlessly.

The figure also shows how the sensors on the user’s equipment react to his movements, emotions and reactions. Thus, it is clear that the user is completely immersed in the virtual space and interacts with it, experiencing events as if they were happening in real time.
3. Semi-Immersive Virtual Reality
A semi-immersive virtual reality encounter amalgamates elements from both fully immersive and non-immersive VR experiences. Utilizing a computer screen or VR headset, individuals can explore independent 3D spaces or virtual worlds. Within these environments, all interactions are directed towards the user, albeit without substantial physical movement beyond visual perception. Navigation in virtual realms occurs via conventional input methods such as mouse control on computers or finger gestures and swipes on mobile devices.

Some objects and the scene around him show that he is exploring independent 3D spaces or virtual worlds. All interactions are directed towards the user, although physical movements are limited and limited to visual perception. To navigate the virtual world, standard control methods are used, such as the mouse on a computer or finger gestures on mobile devices.
4. Collaborative VR
Collaborative Virtual Reality (VR) epitomizes a digital realm where individuals scattered across various locations communicate through avatars or 3D personas. This technology enables multiple users to converge within a shared virtual space simultaneously, fostering real-time interaction, dialogue, and collaborative engagement on diverse undertakings.
The picture shows a virtual space where several people in different places interact with each other through their avatars or 3D characters. Around them are elements of the virtual environment, such as interfaces, objects, as well as areas of communication and collaboration. Avatars can be shown in various poses, communicating or working together on a project. The background may contain futuristic elements reflecting the digital nature of virtual reality.
5. Augmented Reality
Augmented Reality (AR) represents a cutting-edge technology seamlessly blending real-world settings with computer-generated elements. By integrating virtual objects into physical environments, AR empowers users to engage with digital content within their tangible surroundings.
The picture shows a scene from the real world, for example, a cityscape, a street. This scene may contain people, buildings, cars, and other real-world objects. But besides this, the picture also contains virtual elements that are added to the real picture using AR technology. These could be, for example, virtual information panels, navigation signs, or even virtual creatures or objects that interact with the real environment. This image demonstrates the idea of how AR combines the virtual and real worlds, creating a unique and interactive experience for users
6. Mixed Reality
Mixed reality (MR) stands at the forefront of technological innovation, blending the realms of reality and virtuality to craft immersive environments. This cutting-edge technology intertwines virtual elements with the physical world, forging a seamless and dynamic user experience.
In the visual portrayal, a gentleman is depicted adorned with an augmented reality apparatus, notably a helmet. Encircling him are tangible articles of reality: a table, chairs, and various environmental components. Additionally, virtual entities and elements coalesce seamlessly with the corporeal realm, either intermingling with tangible objects or seamlessly integrating into the ambient surroundings, blurring the line between the virtual and the authentic world.
