  • Patent number: 11275432
    Abstract: A system and/or method that uses a body posture of a user to determine and modulate a content mode of a virtual reality system. The content mode may define the manner in which virtual reality content is presented to the user and/or the manner in which the user interacts with the virtual reality content. The user's body posture and/or a change in body posture may cause the content mode and/or the virtual reality content to change accordingly. In some implementations, primary content may be presented to the user according to a first content mode in response to the user sitting. Secondary virtual reality content may be presented to the user according to the second content mode in response to the user standing. As such, a user may initiate a change in the virtual reality content and/or the content mode by standing from a sitting posture and/or sitting from a standing posture.
