A method of changing a virtual world of a computer-implemented game based on real-world locations of players of the computer-implemented game is disclosed. A presence of a player of the computer-implemented game is detected at a physical location. A presence of an additional player of the computer-implemented game is detected at the physical location based on a communication received from the player of the computer-implemented game. An aspect of the virtual world of the computer-implemented game is changed based on the detecting of the presence of the player at the physical location and the detecting of the presence of the additional player of the computer-implemented game at the physical location.

A non-limiting example information processing apparatus that functions as a game apparatus includes a first LCD and a second LCD, and usually, a game screen of a single-play game is displayed on the first LCD and a list screen is displayed on the second LCD. In the list screen, an icon of a player of another game apparatus that is searched as a passer-by is displayed as well as icons of a player of another game apparatus that is registered as a friend and a player of another game apparatus that is determined as an acquaintance. That is, during a time that game processing of the single-play is being performed, the game screen is displayed and a list of a player who is registered and a player who exists in the neighborhood is displayed. The player sends an offer of a battle-play to a desired player through an operation using the list screen at an arbitrary timing during a time that the game processing of the single-play is being performed.

A method of incentivizing location-based actions by groups is disclosed. A group of users of a game networking system is notified that an incentive reward is to be provided based on a number of members of the group performing a location-based action transgressing a threshold. The incentive reward is provided based on the number of members of the group performing the location-based action transgressing the threshold.

Provided is a method for authentication and verification of a user in a virtual world (VU) based upon such criteria as the physical location of a user in the real world and the logical location of the user's avatar in the VU. The disclosed technology combines physical and application aspects of security to enhance security options within virtual environments. In addition to traditional credential-based authentication, physical constraints corresponding to the real world and logical locations in a VU are employed, wherein an authentication server requires each component to be in the proper association state, location or proximity before authenticating a user. Further, the disclosed technology provides for the termination of a user's authentication if the user moves from an approved physical or VU location to an unapproved location. Techniques are provided to track a user's credentials and real-time physical and logical location of a user.

A method of changing a virtual world of a computer-implemented game based on real-world locations of players of the computer-implemented game is disclosed. A presence of a player of the computer-implemented game is detected at a physical location. A presence of an additional player of the computer-implemented game is detected at the physical location based on a communication received from the player of the computer-implemented game. An aspect of the virtual world of the computer-implemented game is changed based on the detecting of the presence of the player at the physical location and the detecting of the presence of the additional player of the computer-implemented game at the physical location.

Aspects of this disclosure relate to rewarding users of an electronic game for real-world physical activity. Further aspects relate to altering virtual items based upon physical activity. An electronic game may comprise or otherwise relate to an online world (such as a Virtual World). Users may be represented through customized graphical representations, such as avatars. An account of a user (or entity) may be associated a virtual region. A threshold level of real-world physical activity may result in obtaining a reward that may be associated with a virtual item. A reward may be configured to result in: (1) altering visual appearance of a virtual item within a virtual region; (2) altering a virtual characteristic of a virtual item, such that the first user may engage in at least one additional virtual activity using that virtual item; and/or (3) acquiring a new virtual item for a virtual region.

A location-based game system is provided. Such a system may take the form of any device (e.g., a wireless telephone) that includes a locating device (e.g., a GPS system). One such location-based game may operate such that the actual, physical location of a user on a physical playfield corresponds to the location of a virtual character on a virtual playfield. Such location based games are referred to herein as actuality games. In one multiplayer actuality embodiment, two game devices may communicate location, and other, information to a remote database such that the two user's may interact on different physical playfields, but play on the same virtual playfield. A number of wireless communications protocols, self-configuration, and auto-download software applications are also provided to optimize integration with, for example, a wireless telephone.

In one embodiment of the invention, service providers generate bloom filters with the user ID codes of registered users and exchange the bloom filters with one another. In response to a request to locate a first user, a first service provider will query its own registration database to determine if the first user is registered with the first service provider. If the first user is not registered with the first service provider, then the first service provider will query its bloom filters to identify other service providers with which the first user may be registered. A positive response from a bloom filter indicates that the first user may or may not be registered with the service provider associated with that bloom filter, and a negative response indicates with certainty that the first user is not registered with the service provider associated with that bloom filter.

Methods of interacting with a mixed reality are presented. A mobile device captures an image of a real-world object where the image has content information that can be used to control a mixed reality object through an offered command set. The mixed reality object can be real, virtual, or a mixture of both real and virtual.

A method of updating virtual worlds based on interactions between real-world items is disclosed. An interaction between a first real-world item and a second real-world item is detected. The first real-world item is a real-world item that is associated with a first player of a computer-implemented game and the second real-world item is a real-world item that is associated with a second player of the computer-implemented game. A virtual world of the computer-implemented game is updated based on the detection of the interaction.
