The first commercial VR headset, the Forte VFX1, was released in 1995 by Forte Technologies.

Oculus, acquired by Facebook in 2014, popularized VR gaming with the release of its Oculus Rift headset in 2016.

VR headsets use stereoscopic 3D technology, presenting slightly different images to each eye, creating the illusion of depth and immersion.

A VR gaming system typically consists of a VR headset, motion controllers, and a powerful graphics card. A gaming console is not a necessary component.

Presence is the feeling of being physically present in a virtual environment, a key aspect of VR gaming.

VR game developers typically face challenges such as motion sickness, high production costs, and lack of content variety, but limited graphics capabilities are not a major concern.

World building is the process of creating the virtual environments and experiences that players explore in VR games.

Social VR, location-based VR, and haptic feedback integration are major trends in VR gaming, while asynchronous multiplayer VR is not a common concept.

Inside-out tracking uses sensors on the VR headset itself to track the user's movements, while outside-in tracking uses external sensors.

Action-adventure, simulation, and puzzle are common types of VR games, while sports games are less common.

Foveated rendering optimizes image quality by focusing on the area where the user is looking, reducing the computational load and improving performance.

Hardware limitations, motion sickness, and high development costs are major challenges, while lack of user-generated content is not a significant issue.

Force feedback technology provides physical feedback to users, such as vibrations or resistance, enhancing the sense of immersion in VR games.

Tethered, standalone, and mobile VR are common headset designs, while inside-out tracking is a technology used in some headsets.

Head-related transfer function (HRTF) technology personalizes the audio experience by simulating how sound waves interact with the user's head and ears, enhancing spatial awareness and immersion.
