  • Patent number: 8696428
    Abstract: A large touch screen gaming table is disclosed that may accommodate, for example, four players. Each player creates a bank of credits at the table and plays a community game independently of other players. In one game, various icons are continuously displayed, and the icons display various wager amounts. Any player may simultaneous touch an icon of any wager and touch a player-active button, and the selected icon reveals a hidden prize credited to that player. In one embodiment, the game is continuous in that the icons are replenished after being selected. The players may play at any speed and in any order. The wagers may be very small and the prizes are generally also small to encourage rapid play. Any player(s) that does not wish to participate in the community game may control the screen to display a variety of individual games on a screen segment.

    Abstract: A video control system has an accelerometer sensor connected to a microcontroller for imparting motion and orientation information to the microcontroller. An encoder/transmitter is connected to the microcontroller and converts a plurality of parallel signals from the microcontroller into a serial data stream which is wirelessly transmitted to a receiver/decoder which converts the serial data back to the original parallel signals. The receiver/decoder is connected to a keyboard encoder that is connected to the keyboard port of personal computer. The accelerometer sensor, microcontroller and encoder transmitter are adapted to be worn on a video player's person.

    Abstract: A computing system translates a world space position of a hand of a human target to a screen space cursor position of a user interface. When the cursor overlaps a button in the user interface, the computing system actuates the button in response to a movement of the hand in world space that changes the cursor position by a depth threshold along a z-axis regardless of an initial z-axis position of the cursor. When the button includes an activation lock, the computing system unlocks the activation lock, prior to button actuation, if the cursor path satisfies unlocking criteria.

    Abstract: A game system moves a player character in a virtual game space in accordance with an operation by a player. Further, the player character's moving amount per predetermined unit time is detected at each predetermined time interval. A predetermined parameter (gage amount) value is calculated at each predetermined time interval based on the moving amount detected at each predetermined time interval. Also, the game system adds the predetermined parameter value calculated at each predetermined time interval for accumulation. In response to a predetermined operation performed by the player, the game system causes the player character to perform a predetermined motion (e.g., special shot) on a condition such that a value obtained as a result of the addition reaches a predetermined value.

  • Patent number: 8303386
    Abstract: The present invention is related to controlling a video game in which ability of a game character is adjusted on the basis of events in the video game. For example, in a baseball video game, if the game player operating a pitcher character keeps selecting a pitching trajectory that a batter character is bad at hitting the ball object, the extent that the batter character is bad at hitting the ball object in the pitching trajectory will be gradually reduced. Therefore, it becomes difficult for the pitcher character to make the batter character out. Accordingly, advantageous level for the pitcher character will be reduced. Therefore, imbalance of the baseball video game is to be solved between the pitcher character and the batter character.

Game processing corresponding to the kind of an acceleration input by means of the controller is executed. For determining the kind, reference timing when acceleration in a first-axis direction is below a threshold value to take on a minimum value is detected. Then, it is determined whether or not an angle between acceleration change vectors before and after the reference timing is equal to or more than a predetermined angle. When the angle is not equal to or more than the predetermined angle, it is determined that the acceleration input is an acceleration input in any one of the two-axis directions, and when the angle is equal to or more than the predetermined angle, it is determined that the acceleration input is an acceleration input in a direction including the two-axis directions as components.

    Abstract: Enhanced realism of a real-time simulator having multiple computer-controlled units results from making the units capable of reacting to only those other units that each of them can be aware of because of their spatial relationships to the unit. Awareness is based upon probabilities; it can persist after a relationship changes; and it can be influenced by a units designation of a target. Each unit selects a target based upon a score incorporating multiple aspects of its tactical situation, and can change targets when the situation changes. A unit selects a strategy in response to which of a set of tactical configurations exist between the unit and its target; the strategy can change short of completion when the configuration changes. A plan produces guidance commands from the high-level strategy. The guidance commands are converted into control settings for guiding the subject unit using a physics engine for simulating the physical dynamics of the unit.
