Abstract: A user menu is created by retrieving at least one animation frame that corresponds to a user selected portion of stored subject matter. The animation frame or frames are displayed at a portion of the display and aid the user to accurately enter the subject matter at a desired location.

Abstract: A game involves establishing a Wi-Fi connection for retrieving a template used to create a level for the game. A play test is conducted to determine if the created level of the game can be played. The created game level can be shared with other players and/or submitted as a contest for play and competition judging by other players.

Abstract: In the context of a video game, multimedia presentation or other application, multiple sound sample files are read out simultaneously and mixed together. The volumes and/or pitches of the wave tables are parameterized to allow a single parameter (e.g., power, intensity, etc.) to simultaneously control the multiple read out processes. The control parameter may be, for example, responsive to a user-manipulable control, such as a joystick. Sound effects produced using this technique are rich and interesting, and the user feels as if he or she is directly controlling the effect.

Abstract: Example systems and methods involve a video game system that has a touch sensitive display screen that can be used to supply inputs used in video game control. In one example system and method, a user or player draws movement patterns on the touch sensitive display screen. The drawn movement patterns are stored and a game object can be moved in accordance with a drawn movement pattern selected from the memory by the user.

Abstract: A method and apparatus for modeling a track in video games that enables efficient collision detection between a game object (such as a racecar wheel) and the track. The invention provides an infinitely smooth track for use in collision detection through the novel use of arcs and splines. The invention enables relatively small amounts of data to be used to model and express relatively large gameplay courses, such as race tracks and the like. The arcs and splines enables quick and efficient look-up of the location of the tire on the track and calculation of the distance from the wheel to the track for loading purposes.

Abstract: Transformation matrices describing the motion of an articulated reference object specify translations of the reference object and/or its articulated parts, and are relative to the origin of the object's coordinate system. During the real-time animation process, a connection matrix is saved to represent the current transformation status of the animated object. This connection matrix being obtained by continuously concatenating an external transformation (if any) with the next animation step. This process allows efficient insertion of external transformations (e.g., resulting from operating real-time interactive user controls). Use of absolute transformations to develop the connection matrix allows a first animation sequence to be interrupted at any arbitrary point and immediately, smoothly followed by a second animation sequence (e.g., walking can be interrupted at any time and turned into running, jumping, etc.).
