The patent covers cameras, computers, and projectors that display an interactive screen on a physical surface.
"The projected content may include electronic books, videos, images, interactive menus, or any other sort of visual content," Amazon said in its patent filing. "Various types of cameras and sensors may be used to capture images representing the scene and a person's hand within the scene."
Meanwhile, YouTube is working to become the leading provider of virtual-reality content, whether its creators want to go 360 or not.
The video-sharing website recently introduced a new video format called VR180, which allows creators to film as they normally would but is compatible with virtual-reality goggles such as Google's (GOOGL) Cardboard, Daydream and PSVR. Cameras that support the format will be available this winter, according to a press release.
"We've heard from creators and viewers that you want to make and see even more immersive videos on YouTube," the announcement said. "VR180 will unlock opportunities for anyone looking to easily make VR memories."
VR180 allows creators to set up their camera as they normally would to capture about 180 degrees, but the format lets viewers watch in high resolution on their computer or mobile device or stereoscopically in 3D, which means objects closer to the camera appear closer to the viewer and objects farther away appear farther. The other 180 degrees of the virtual-reality sphere will appear black.
Creators will be able to livestream the format as well as edit the video with Premiere Pro from Adobe (ADBE) , which recently acquired SkyBox technology, which builds transitions, titles and effects in VR applications and 360-degree videos.
Google is working with Xiaomi Inc.'s Y.I. Technology, Lenovo Group Ltd. (LNVGY) , and LG Corp. to create the cameras and a certification program will be available to other manufacturers such as 3DV Systems Ltd.'s ZCam.
For more than two years, YouTube invested in supporting 360 and virtual reality on its platform, according to the release.
Here are some other top names already playing in the space.
At its Worldwide Developers Conference, Apple held a virtual-reality Star Wars demonstration that showed how it is diving into virtual reality.
The company announced its new graphics application programming interface, Metal 2, would allow developers to render directly on a device such as a VR headset, according to The Verge. Lower-end iMacs and Macbooks also will now be able to support external graphics processing units to play VR, and virtual reality gaming software and hardware like Valve Corp.'s SteamVR and HTC Vive are also now compatible with Mac.
Oculus Visiontech Inc. (OVTZ) has designed goggles that put people into a virtual reality. It also has touch controllers that allows people to interact with the virtual reality with hand controllers such as when playing video games. It has also partnered with PC manufacturers to create systems that that are compatible with Oculus Rift and Touch.
Facebook (FB) Spaces is an app that creates a virtual-reality social space with Facebook-owned Oculus Rift VR goggles. The app allows users to create a digital avatar based on their profile picture, and they can spend time with people on their friends list in a virtual lounge. The Facebook Spaces app launched in beta in April.
HTC Corp. in conjunction with Valve Corp. created HTC Vive, which is a high-end virtual reality headset. Its bundle also includes two controllers, base stations for safety, ear buds and two games. It is also compatible with Valve's virtual-reality digital gaming platform, SteamVR.
