The term "Field of View" (FOV) refers to the extent of the observable area that can be seen at any given moment. It is commonly used in various fields, including photography, video games, and virtual reality. A wider FOV allows for more of the environment to be seen, while a narrower FOV focuses on a smaller area. In human vision, the FOV is approximately 180 degrees horizontally and 130 degrees vertically. This range can vary based on individual differences and conditions. In technology, such as cameras or virtual reality headsets, FOV is crucial for creating immersive experiences and capturing detailed images.
