The virtual location of a player in a location-based game is determined from the real-world location of the player's client device. The location-based game provides the player access to one or more chat room based on their location. To determine the locations of chat room, a server analyzes player locations in a geographic region, clusters player locations to identify centroids, and adjusts the clusters based on constraints. The server selects chat room locations (e.g., at points of interest) to more evenly balance the number of players in each chat room while complying with one or more restraints on the size of the geographic area served by each chat room.

In one implementation, a method comprises: obtaining an input from a client device indicating an entry transaction between an avatar and a portal of a modeled space; in response to obtaining the input from the client device indicating the entry transaction between the avatar and the portal of the modeled space, determining an identifier associated with the avatar; determining whether a custom destination has been defined for the portal based on the identifier for the avatar; causing the avatar to enter a default destination environment for the portal according to a determination that a custom destination has not been defined for the portal; and causing the avatar to enter a custom destination environment that is distinct from the default destination environment according to a determination that a custom destination has been defined for the portal.

Provided is a simulation method and system for real-time broadcasting. A simulation method may include verifying an action set for a mechanical object, and displaying a movement of the mechanical object in response to the action using a line that connects a start location of the movement and an end location of the movement.

An image processing unit 118 generates a distribution image including a game image. A distribution processing unit 126 distributes the distribution image to one or more of information processing terminals through a shared server. A participation processing unit 128 accepts play requests of viewing users operating the information processing terminals and approves a game play of one of the viewing users who has made a request for a play. An application execution unit 110 processes a game using operation information transmitted from the information processing terminal operated by the viewing user the game play of which has been approved.

A video game processing apparatus for controlling progress of a video game is provided. In the video game, a plurality of players addresses a common task. The video game processing apparatus includes a processor and a display controller. The processor specifies a task corresponding to a task providing request of a first player and generates player related information of a second player corresponding to the specified task. The display controller displays, on a task screen, an image in association with the second player. The image satisfies a display condition during progress of the specified task. The task screen indicates the specified task.

An information processing apparatus is connected to a peripheral apparatus that includes sound inputting means for outputting a sound signal representative of sound of surroundings. The information processing apparatus performs control such that, in a case where sound input is required in processing of an application determined in advance, in a state in which a sound signal accepted from the peripheral apparatus is cut off, the sound signal accepted from the peripheral apparatus is accepted and the sound signal is used only in the processing of the application determined in advance.
