Technologies are generally described for providing a notification to a player playing a gesture-based game of a potentially dangerous condition. In some examples, a safety component of a gesture-based game system includes a gesture range determination unit configured to determine a gesture range associated with a gesture-based game; a detection unit configured to detect a movement of an object; and an alarm unit configured to generate an alarm in response to a determination based on the movement of the object which is within the gesture range.

A method for real time processing of images providing a real time preview of face images for interaction with a game environment. Images from one or more image sensors are processed providing a modified image of a certain size and certain shape, for algorithmically detecting and tracking faces in the modified image for a real time preview of face images overlaid on a game environment. The real time preview of face images is configured for user control for interaction with the game environment. A facial gesture control functionality is disclosed for the execution of game commands allowing control of the real time preview of a face images for interaction with the game environment. The method of the present invention further discloses real time processing of images from a second image sensor for a real time preview of a second face images for interaction with the game environment. The present invention further discloses a method for real time processing of images from a first and second image sensor for a real time preview of face images overlaid on a real time preview of background images.

The present disclosure provides a game operation optimization method and a mobile device. The method includes: in response to detecting that a game application is operating on the mobile device, reading a button configuration file corresponding to the game application; in response to detecting a first button event corresponding to the first button, converting the first button event into a second button event corresponding to the second button according to the button configuration file; and controlling a first content of the game application according to the second button event.

Provided are a server, a method of controlling a server, and a program that can increase the variations on methods for acquiring an item or the like and enhance interest in a game. Included are receiving, from a user, an item change request for changing first item data; displaying, to the user, a selection screen to display a plurality of options after receiving the item change request; and providing the user with second item data when a selected option on the selection screen is a correct answer.

An information processing apparatus performs predetermined game processing based on operation inputs from a plurality of operation devices and generates a game image based on the game processing. Then, in accordance with the number of the operation devices used for the game processing, the information processing apparatus generates a game image for multiplayer play using a split screen, and performs a restriction process for, in a case where an output destination to which the game image is to be output is a display, placing a restriction so that multiplayer play is not performed by players exceeding a predetermined number of players, and in a case where the output destination to which the game image is to be output is an external display, not placing the restriction.

A haptic feedback planar touch control used to provide input to a computer. A touch input device includes a planar touch notice that inputs a position signal to a processor of the computer based on a location of user contact on the touch surface. The computer can position a cursor in a displayed graphic environment based at least in part on the position signal, or perform a different function. At least one actuator is also coupled to the touch input device and outputs a force to provide a haptic sensation to the user contacting the touch surface. The touch input device can be a touchpad separate from the computer's display screen, or can be a touch screen. Output haptic sensations on the touch input device can include pulses vibrations, and spatial textures. The touch input device can include multiple different regions to control different computer functions.

A method for determining the position of a controller device, comprises: receiving dimensions of the display input by a user of the computer-based system; capturing successive images of the display at the controller device; determining a position of the controller device relative to the display based on the dimensions of the display and a perspective distortion of the display in the captured successive images of the display; providing the determined position of the controller to the computer-based system to interface with the interactive program to cause an action by the interactive program.

A real world image captured by a real camera such as an outside right imaging unit 23b is acquired, a synthesized image is generated by synthesizing the acquired real world image and a virtual image depicting a first virtual object such as an enemy object EO, in such a manner that the first virtual object such as an enemy object EO appears to be present behind the real world image, and the synthesized image thus generated is displayed on a display device.

A method and system (10) is provided for playing an interactive mobile device based game system though a communication network. The communication network includes at least one system central server (13) and database (14) accessible to the internet or other communication networks. The system further includes any number of mobile devices (15), (16) and (17). Each mobile device includes software or a software application for communicating with the system server. In playing the game, users or players accrue points or otherwise advance in the game as they compete or obverse events which occur in real life situations in their geographic location. The events are entered into the central server and verified by communicating requests from the central server to the mobile devices of other players of the game.

A communication game system includes a plurality of game apparatuses which are able to wirelessly communicate with each other. Each of the game apparatus registers identifying information of an opponent obtained by a short-distance wireless communication or by user's manual input in a friend list. Thereafter, the game apparatus connects to the Internet, and inquires whether it is possible to communicate with an opponent in the friend list over the network. If it is possible to communicate, the game apparatus obtains an address of the opponent to make a network communication. Even if a user makes a short distance wireless communication with a friend to exchange and register the identifying information or registers the friend by hand and then is parted from the friend, the user can safely communicate with the friend across the network without being exposed to unknown players. In a case that an additional opponent is to be added to the multiplayer game session, one of the participants transmits identifying information to introduce the communicating opponents to each other. The game apparatuses introduced to each other make a communication over a network, and add the identifying information of the opponents to the friend list, if necessary.
