Basics of virtual reality:
Applications, technologies and FAQs

What is Virtual Reality?

Virtual Reality (VR) refers to a computer-generated, interactive environment that allows users to immerse themselves in a three-dimensional, digital world. VR technology is used in areas such as entertainment, education and medicine to create immersive experiences and training opportunities.

The development of virtual reality

Since the 1960s, VR has evolved from experimental prototypes such as the Sensorama to modern headsets such as the Meta Quest 3 and Pico 4 developed. Today, these devices offer affordable and powerful options for an immersive experience.

Differences between VR, AR and MR

• Virtual Reality (VR): Complete immersion in a digital world.
• Augmented Reality (AR): Overlaying digital content on the real world.
• Mixed Reality (MR): Combination of real and virtual elements with interaction possibilities.

Technical requirements

Modern VR devices such as the Meta Quest 3 no longer require high-end PCs. These Standalone headsets offer outstanding performance without additional hardware. A gaming PC with a current graphics card such as the Nvidia RTX 3060 is sufficient for PC-connected headsets.

Areas of application for virtual reality

• Education: Virtual excursions and training environments.
• Medicine: Surgical simulations and therapy applications.
• Gaming: Immersive gaming experiences.
• Architecture: Realistic visualizations.
• Marketing: Emotional and interactive brand experiences.

How VR is changing marketing

VR allows companies to present their brand messages through emotional and immersive experiences. This gives customers new perspectives on products and services that go beyond traditional marketing methods.

Technological innovations

Modern headsets such as the Meta Quest 3 and the Apple Vision Pro use technologies such as artificial intelligence and haptic feedback to create more realistic and personalized experiences. However, the development of lighter and more ergonomic devices remains a goal.

FAQ on virtual reality

What is virtual reality (VR)?

Virtual reality is a digital simulation that offers users an immersive environment. With the help of VR headsets and controllers, users can immerse themselves in interactive 3D worlds that are realistically designed. This technology is used in many industries such as education, medicine and gaming to provide virtual experiences that go beyond traditional media.

What technologies are used for VR?

The most important technologies for VR include:

• VR headsets: Devices such as the Meta Quest 3 or Pico 4, which generate visual and auditory stimuli.
• Sensors: For capturing head and hand movements for precise interaction.
• Software: Applications and games that are specially developed for VR.

These components work together to create a seamless and immersive experience.

How does VR work?

Virtual reality works by transmitting visual and audio information to the user, creating the impression of a real world. Technologies such as head tracking and hand tracking record the user's movements and adapt the virtual environment in real time. This creates a realistic sense of immersion, allowing the user to interact with objects and people in the virtual world.

Is VR safe to use?

VR is safe if its use follows certain guidelines:

• Take regular breaks to avoid eyestrain.
• Sufficient space to prevent unintentional collisions.
• Use of modern devices that reduce nausea through optimized refresh rates.

As long as these points are observed, VR is a safe and pleasant technology.

How can I get started with VR?

Getting started with VR is now easier than ever. Beginners can choose a standalone headset such as the Meta Quest 3 or Pico 4, which are easy to set up and affordable. For more demanding applications, a PC-connected headset with powerful hardware is recommended. Many platforms offer free VR content to get your first experience.
