Abstract: The present invention provides a highly scalable architecture for a three-dimensional graphical, multi-user, interactive virtual world system. In a preferred embodiment a plurality of users interact in the three-dimensional, computer-generated graphical space where each user executes a client process to view a virtual world from the perspective of that user. The virtual world shows avatars representing the other users who are neighbors of the user viewing the virtual word. In order that the view can be updated to reflect the motion of the remote user's avatars, motion, information is transmitted to a central server process which provides positions updates to client processes for neighbors of the user at that client process. The client process also uses an environment database to determine which background objects to render as well as to limit the movement of the user's avatar.

Abstract: A keypad used for dialing telephone numbers to establish a communications link is also used to display game moves. Once the communications link is established between two or more parties, their terminals are placed in a game mode which activates inband signal detection and player identification circuitry located within the terminals. Multi-colored indicators (e.g., LEDs) and player identification displays (e.g., LCDs) at each terminal are activated, their color being dependent upon the source of received instructions. Player identification indicators are incorporated into a touch-tone keypad located on each of the terminals. Each key of the keypad has two or more color-coded indicators incorporated within, each color representing a particular player's move. Thus, the touch-tone keys represent a game board and/or game accessory when the terminal is placed in a game mode.

Abstract: A crossing network that matches buy and sell orders based upon a satisfaction and quantity profile is disclosed. The crossing network includes a number of trader terminals that can be used for entering order. The orders are entered in the form of a satisfaction density profile that represents a degree of satisfaction to trade a particular instrument at various (price, quantity) combinations. Typically, each order is either a buy order or a sell order. The trader terminals are coupled to a matching controller computer. The matching controller computer can receive as input the satisfaction density profiles entered at each one of the trading terminals. The matching controller computer matches orders (as represented by each trader's satisfaction density profile) so that each trader is assured that the overall outcome of the process (in terms of average price and size of fill) has maximized the mutual satisfaction of all traders. Typically, the matching process is anonymous.
