Virtual reality
VR is most commonly used in entertainment applications such as gaming and 3D cinema. Consumer virtual reality headsets were first released by video game companies in the early-mid 1990s. Beginning in the 2010s, next-generation commercial tethered headsets were released by Oculus (Rift), HTC (Vive) and Sony (PlayStation VR), setting off a new wave of application development. 3D cinema has been used for sporting events, pornography, fine art, music videos and short films. Since 2015, roller coasters and theme parks have incorporated virtual reality to match visual effects with haptic feedback .
HTC Vive
In July 2016, VR news website Road to VR used game session figures from the Steam VR platform to estimate that approximately 100,000 Vive headsets had been shipped since launch. In the same month, SensoMotoric Instruments (SMI), a computer vision company, integrated its eye tracking technology in the HTC Vive to turn it into a dedicated eye tracking solution for research and professional applications. In November 2016, Vive announced that it would begin the first retail sales of its headsets at JB Hi-Fi and Harvey Norman stores in Australia later that month.
