Methods and systems for using a position of a mobile device with an integrated display as an input to a video game or other presentation are presented. Embodiments include rendering an avatar on a mobile device such that it appears to overlay a competing user in the real world. Using the mobile device's position, view direction, and the other user's mobile device position, an avatar (or vehicle, etc.) is depicted at an apparently inertially stabilized location of the other user's mobile device or body. Some embodiments may estimate the other user's head and body positions and angles and reflect them in the avatar's gestures.

A non-transitory computer-readable recording medium having computer-readable instructions stored thereon, which when executed, causes a computer to execute a process of a game program, is provided. The process includes a step (a) of setting a default position of a virtual camera; a step (b) of calculating an outer edge of multiple objects arranged in a given region in the virtual space; a step (c) of determining a target position in an interior of the outer edge, to which the virtual camera is directed; a step (d) of adjusting a height of the virtual camera at the default position so as to display all of the plurality of objects in the region when the virtual camera is directed from the default position to the target position; and a step (e) of operating the virtual camera to be directed to the target position from the adjusted height of the default position.

A server apparatus includes a communication interface, a memory, and a processor configured to execute an instruction command stored in the memory to identify other players located within a predetermined range of a distance from a first terminal device, when the communication interface receives position information detected by the first terminal device held by a first player from the first terminal device, to determine whether a non-player character appears in a virtual space of a game application in response to a number of the identified other players, and to transmit non-player information about a non-player character to the first terminal device when the processor determined that the non-player character appears in the virtual space.

An avatar or avatar environment to visualize data may be provided within a social networking system or service, for example as part of the Internet, and/or within a desktop widget, panel, gadget, or the like. The avatar may further evolve or alter its appearance, animation, or other visual or audio characteristics in response to the data or other input such as athletic activity performed by a corresponding user. In particular, the avatar of an embodiment may respond to and provide visualization of athletic or sport performance data.

The invention discloses a multi-human tracking system and method with single Kinect for supporting mobile virtual reality applications. The system can complete the real-time tracking of users occluded in different degrees with a single Kinect capture device to ensure smooth and immersive experience of players. The method utilizes the principle that the user's shadow is not occluded when the user is occluded under certain lighting conditions, and converts the calculation of the motion of the occluded user into a problem of solving the movement of the user's shadow, and can accurately detect the position of each user, rather than just predicting the user's position, thereby actually realizing tracking.
