Virtual reality (VR) is a simulated experience that employs pose tracking and 3D near-eye displays to give the user an immersive feel of a virtual world. Applications of virtual reality include entertainment, education and business. Other distinct types of VR-style technology include augmented reality and mixed reality, sometimes referred to as extended reality or XR, although definitions are currently changing due to the nascence of the industry.
Valve Corporation, also known as Valve Software, is an American video game developer, publisher, and digital distribution company headquartered in Bellevue, Washington.

Portal is a series of first-person puzzle-platform video games developed by Valve. Set in the Half-Life universe, the two main games in the series, Portal (2007) and Portal 2 (2011), center on a woman, Chell, forced to undergo a series of tests within the Aperture Science Enrichment Center by a malicious artificial intelligence, GLaDOS, that controls the facility. Most of the tests involve using the "Aperture Science Handheld Portal Device" – nicknamed the portal gun – that creates a human-sized wormhole-like connection between two flat surfaces. The player-character or objects in the game world may move through portals while conserving their momentum. This allows complex "flinging" maneuvers to be used to cross wide gaps or perform other feats to reach the exit for each test chamber. A number of other mechanics, such as lasers, light bridges, high energy pellets, buttons, cubes, tractor funnels and turrets, exist to aid or hinder the player's goal to reach the exit.

The company was sold to the British company Ultrahaptics in 2019, which rebranded the two companies under the new name Ultraleap.
