Microsoft patent describes video games projected onto an entire room.
Microsoft’s Future Immersive Gaming System describes an idea for a gaming system that uses an HDTV as a primary display, with a peripheral image projected onto other surfaces in the room to immerse the player in the game.
The peripheral image appearing on the user’s wall will be configured to appear to be as an extension of the primary image that is shown on their TV. As a user perceives the peripheral image with the user’s peripheral vision, the user may be situationally aware of images and objects in the peripheral vision while being focused on the primary image.
In the example shown in patent FIG. 1, we see that the user is focused on the gameplay on his TV but may be aware of an approaching video game enemy from the user’s perception of the peripheral image displayed on his back wall. In some embodiments, the peripheral image is configured so that, to a user, the peripheral image appears to surround the user when projected by the environmental display. Thus, in the context of the gaming scenario shown in FIG. 1, the user may turn around and observe an enemy sneaking up from behind.
