Abstract: A processor-based gaming machine running wager-based games can include an exterior housing, a master gaming controller, a display device, and an anonymous player tracking device adapted to detect passively biometric information from players to facilitate the anonymous tracking of gaming activities without the use of traditional player tracking instruments. A player tracking system can include multiple such gaming machines, a database storing a plurality of player profiles that include biometric data, and a remote player tracking server configured to receive passively detected biometric data regarding anonymous players, determine whether the received biometric data is associated with existing player profiles, attribute credit for the anonymous gaming activity if it is, and create a new player profile if it is not. Player profiles can include multiple biometrics for each player, and confidence levels can be associated with a given biometric to a profile and a given gaming session to a profile.

Abstract: A composite touchscreen incorporates acoustic pulse recognition sensing and capacitive sensing technology. The hybrid screen incorporates the advantages of each technology while minimizing the drawbacks. When such a screen is incorporated in a gaming device specialized gestures and functions can be implemented that enhance the interface, the range of games, and the gaming experience.

Abstract: The disclosure relates generally to different devices, methods, systems, and computer program products for a gaming machine that includes a projection button panel. The projection button panel may include one or more projection buttons configured to receive user input. Each projection button may include a projection surface disposed within the button capable of being viewed by a player of the gaming machine. Each projection button may also include a button projector proximate to the projection surface. Further, each projection button may be configured to receive button image information and to project, based on the received button image information, a button image onto the projection surface. Each projection button may also include one or more sensors capable of being activated responsive to activation of the button. The gaming machine may also include one or more controllers in communication with the main display and the button assembly.

Abstract: A gaming machine reel having a motor capable of rotating the reel operatively coupled to a controller to control a reel rotation speed, a support mechanism coupled to the motor having an outer circumferential region, a rotatable display mounted on the outer circumferential region operable to rotate about an axis of the reel. The rotatable display may be used to display game play indicia utilized in a wager-based game of chance. A game controller coupled to the rotatable display may be configured to determine a portion of the rotatable display that is visible through a viewing window on the gaming machine at a particular, determine pixel locations associated with the visible portions and map visual content to the visible portions as a function of time while the rotatable display is rotating.

Abstract: A gaming system including an electronic gaming machine (EGM) having a backlit video display, is described. In particular, the EGM can be configured with a display that allows display elements, such as mechanical stepper reels, positioned behind the display to be either revealed or obscured by using directional lighting. The display assembly can include an edge-lit light guide having different regions that can extract light coming from a particular direction.

Abstract: A gaming system including an electronic gaming machine (EGM) having a multi-layer display is described. In particular, the EGM can be configured with a display that provides a 3D-like image. An acousto-optical modulator interstitial component can be positioned between two liquid crystal displays to mitigate moiré interference. A piezoelectric transducer can be attached to a glass interstitial component or to a display panel of a multi-layer display in order to control the moiré interference.

Abstract: A video display having a window opening includes a graphic display portion configured to display graphical indicia, one or more light sources, and a light guide. The light guide is configured to receive light from the one or more light sources and provide the light as backlighting to the graphic display portion. The light guide also includes a light guide shutter configured to selectably transition between a closed state and a transparent state. The light guide shutter is configured to allow a user to see through the electronic display when the light guide shutter is in its transparent state.

Abstract: A physical device that triggers a deal of a video card is described. The physical device triggers the deal when a subject moves an object of the subject on the physical device.

Abstract: Methods, systems, and apparatus are provided for displaying game related information on gaming machines. The gaming machines include two or more game presentation devices such as rotating reels, video display screens, touch screens, etc. One or more of these game presentation devices can be moved into and out of position with respect to other game presentation devices. This may allow, among other things, flexibility in presenting different types of games or different game features within a single game.

Abstract: A gaming machine includes a rotating object that has at least one configurable surface that may be configured electronically. The rotating object may be synchronized with a video display. Configurable surfaces can use bistable materials, electroluminescent materials, LCDs, LEDs, OLEDs, projection, or other techniques. The appearance of the rotating object is changed without physically changing the rotating object.

Abstract: Techniques for forming and using formal partnerships are disclosed. Two or more entities (e.g., individual players, groups, organizations) can form a partnership for the purpose of participating in one or more games. In effect, a game can be played for a partnership without the active participation of all the entities (or partners) that have formed the partnership. The game can, for example, be played by one or the partners or an authorized representative of the partnership. When a game is played on behalf of a partnership, the gaming activity is effectively tracked and verification data is stored for the partnership. Verification data can be made available to allow the partners to verify the outcome of the game.

Abstract: A gaming machine may be activated by an individual player for subsequent play by displaying to the gaming machine, without physical contact with the gaming machine, a card carried by the player. The card carries indicia which may include suitable electronic memory, to be sensed by apparatus associated with the gaming machine, to cause the wireless transfer of individualized data concerning the player from the card to the gaming machine or to a computer network that is associated with the gaming machine. The data is evaluated against a stored database, which database may include identification of the card holder. The data is then evaluated against the stored database, and the gaming machine is activated for subsequent play upon favorable evaluation of the data.

Abstract: A gaming machine includes a gaming machine controller configured to control game play on the gaming machine, and a wheel assembly rotatably coupled to the gaming machine controller. The wheel assembly includes a front portion having an inner surface and at least one projector, wherein the at least one projector is configured to rotate with the wheel assembly and to project an image across at least a portion of the inner surface during game play.

Abstract: A multi-layer projection display including first and second panels separated by a predetermined distance, wherein at least a portion of the first panel overlaps at least a portion of the second panel, and the first panel is disposed between a viewing location and the second panel. The display also includes a controller configured to cause the first and second panels to alternate between substantially opaque and substantially transparent states at a determined frequency, such that the first panel is substantially opaque when the second panel is substantially transparent, and the second panel is substantially opaque when the first panel is substantially transparent. The display further includes a projector configured to project an image onto the first panel when the first panel is substantially opaque, and further configured to project the image onto the second panel when the second panel is substantially opaque.
