Are you curious about how VR works? It seems illogical that a headset can give the illusion that you are skiing on a mountain when actually you are playing in the comfort of your own home. With this technology, we’re able to replace our senses with something, which is beyond our imagination.
Immersive media developers and innovators are experimenting with new ways of displaying content that takes advantage of tools that change how we feel, what we see, and what we hear. Let’s learn more about technology.
The Basics of Virtual Reality
As humans, we perceive the world based on rules that have been developed over time. Our perception is shaped by what we see, hear, and touch. Virtual reality designers use the basic rules of perception and the way we perceive the world to create environments that feel exactly like the outside world. In essence, VR headsets are mere machines that substitute our surroundings with something we have created. Wearable headsets have gyroscopic sensors, accelerators, and magnetometers that determine how you move and monitor your interactions with a virtual environment.
Virtual Reality Evolution’s Crucial Components
Currently, virtual reality has evolved to offer more immersive experiences. Though we haven’t yet mastered the experience, the innovations continue to come. Right now, the most impressive virtual reality experiences offer the following features.
FPS and Field of View
For VR developers, the field of view is a major concern. To immerse us in a virtual environment, it must mimic the perspective of our own eyes. Humans usually have a much broader field of view than headsets typically can provide. An average human can see around 210 degrees of surrounding content at a time. With VR, that’s 180 degrees. You see around you based on the field of view in your headset and how much it mimics your current environment. Another visual term that defines how VR works is frame rate.
Audio and Sound Effects
It is very common to think of VR as a visual experience. In reality, VR tools try to immerse you fully into a new environment. It is also important to have a 360-degree sound to give you the feeling that you are in a new environment. Virtual reality technology uses spatial audio to simulate a realistic audio landscape. The better the audio quality, the more immersed you feel by the sound that appears to come from the side, above, and behind you. Spatial audio assists in guiding you through VR experiences in a way that developers want by showing you where to turn.
Keeping Track of Position and Head
VR is truly engaging because it allows you to move around in a virtual space, and a virtual environment will adapt to your movements accordingly. Similarly, your device’s position tracking capabilities are based on a free-form system, which allows you to choose between 3 degrees of freedom or 6 degrees of freedom.
In headsets that use six axes of motion, the position of your head in a room can be calculated, as can the direction in which it is pointed. Thus, you can move freely through space.
