擴增實境
Virtual reality headsets such as the Oculus Rift, HTC Vive, and Google Daydream View aim to create a more immersive media experience by either simulating a first-person experience or displaying the media in the user's full field of vision. Television, films, video games, and educational simulators have been developed for these devices to be used by working professionals and consumers. In a 2014 expo, Ed Tang of Avegant presented his "Smart Headphones". These headphones use Virtual Retinal Display to enhance the experience of the Oculus Rift. Some augmented reality devices fall under the category of wearables. Augmented reality glasses are currently in development by several corporations. Snap Inc.'s Spectacles are sunglasses that record video from the user's point of view and pair with a phone to post videos on Snapchat. Microsoft has also delved into this business, releasing Augmented Reality glasses, HoloLens, in 2017. The device explores using digital holography, or holograms, to give the user a first hand experience of Augmented Reality. These wearable headsets are used in many different fields including the military.
