The embodiments described herein relate generally to table games and, more specifically, to a portable gaming apparatus for use at gaming tables.
Casinos and other forms of gaming make up a growing multi-billion dollar industry both domestically and abroad. Within such environments, table games are an immensely popular form of gaming and are a substantial source of revenue for gaming operators. Such table games are well known and may include for example, poker, Blackjack, baccarat, craps, roulette, and other traditional games. Moreover such table games may include more recently introduced games such as Paigow, Caribbean Stud®, Spanish 21, and Let It Ride® (Caribbean Stud is a registered trademark of Mikohn Gaming Corporation of Las Vegas, Nev., and Let It Ride is a registered trademark of Shuffle Master, Inc. of Las Vegas, Nev.). In a typical gaming event at a gaming table, a player places a wager on a game, whereupon a winning may be paid to the player depending on the outcome of the game. As is generally known, a wager may involve the use of cash or one or more chips, markers or the like, as well as various forms of gestures or oral claims. The game itself may involve the use of, for example, one or more cards, dice, wheels, balls, tokens or the like, with the rules of the game and any payouts or pay tables being established prior to game play. As is also known, possible winnings may be paid in cash, credit, one or more chips, markers, or prizes, or by other forms of payouts.
Although standard, fully-manual gaming tables have been around for many years, gaming tables having more “intelligent” features are becoming increasingly popular. For example, many gaming tables now include automatic card shufflers, liquid crystal display (LCD) screens, biometric identifiers, automated chip tracking devices, and even cameras adapted to track chips and/or playing cards, among various other items and devices.
At least some known gaming tables, including both standard gaming tables and electronic gaming tables, include such added items and devices. However, such gaming tables currently lack a reward feature for players that qualify for a bonus round. Accordingly, it is desirable to provide a table top gaming device for use during a bonus round.
In one aspect, a portable gaming device is provided including a base, a user-actuated wheel coupled to the base such that the wheel is rotatable relative to the base, and a display configured to display an image corresponding to a position of the wheel to a player.
In another aspect, a method of game play using a portable gaming device is provided. The method includes presenting the gaming device to a player, rotating a wheel coupled to a stationary base, determining a position of the wheel, and displaying an image to the player corresponding to the position of the wheel.
In another aspect, an apparatus for implementing a wheel-based bonus game is provided. The apparatus includes a base, a wheel coupled to the base such that the wheel is rotatable relative to the base, an indicator for indicating a position of the wheel relative to the base, and a display configured to display an image to a player corresponding to the position of the wheel.
The included drawings are for illustrative purposes and serve only to provide examples of possible structures and process steps for the disclosed inventive playing systems and methods for table games. The drawings do not limit any changes in form and detail that may be made to the invention by one skilled in the art without departing from the spirit and scope of the invention.

It will thus be apparent to one skilled in the art that the present invention may be practiced without some or all of these specific details. In other instances, well known process steps have not been described in detail in order to avoid unnecessarily obscuring the present invention. Other applications are possible, such that the following example should not be taken as definitive or limiting either in scope or setting. In the detailed description that follows, references are made to the accompanying drawings, which form a part of the description and in which are shown, by way of illustration, specific embodiments of the present invention. Although these embodiments are described in sufficient detail to enable one skilled in the art to practice the invention, it is understood that these examples are not limiting, such that other embodiments may be used and changes may be made without departing from the spirit and scope of the invention.
Various advantages of the present invention include the introduction of devices for use with a gaming table that is more fully automated, providing added benefits to the gaming operator, and also having various automated and player-friendly items and functionalities. The devices described herein may be used to, for example, award a bonus game to one or more players.
Although gaming table 100 is illustrated in
In one embodiment, one or more IR light sources 212 are coupled to, such as fixedly secured to, frame 204. In the exemplary embodiment, IR light source 212 includes a plurality of light emitting diodes (LEDs) and the light produced by IR light sources 212 is directed upward towards an underside of display surface 208. Infrared light from IR light sources 212 passes through a translucent layer 214 of display surface 208 and is reflected from any tabletop devices, such as device 206, that are positioned on, or near, display surface 208. In the exemplary embodiment, translucent layer 214 is fabricated from a sheet of vellum, or any other suitable translucent material that has light diffusing properties. More specifically, after passing through translucent layer 214, the IR light may exit through display surface 208 without illuminating any tabletop devices 206. Alternatively, the IR light may illuminate one or more tabletop devices 206, that are positioned on display surface 208. Moreover, the IR light may illuminate one or more tabletop devices 206 that are positioned adjacent to, but not touching, display surface 208.
Moreover, in the exemplary embodiment, a digital video camera 216 is coupled to frame 204 below display surface 208. More specifically, video camera 216 is positioned with respect to display surface 208 to facilitate maximizing an amount of IR light reflected from tabletop devices 206 positioned above display surface 208. Video camera 216 includes an IR pass filter 218 that transmits only IR light and prevents ambient visible light from traveling through display surface 208. Because it is desired that video camera 216 produce an output signal representative of only the IR light reflected from tabletop devices 206, a baffle 220 is positioned between IR light source 212 and video camera 216 to substantially prevent IR light that is directly emitted from IR light source 212 from entering video camera 216. As such, IR light reflected from tabletop devices 206 may be reflected through translucent layer 214, through IR pass filter 218, and into video camera 216. Alternatively, IR light reflected from tabletop devices 206 may be reflected or absorbed by other interior surfaces within table 200 without entering video camera 216.
In the exemplary embodiment, translucent layer 214 substantially diffuses both incident and reflected IR light. As such, those tabletop devices 206 positioned above display surface 208, but not in contact with display surface 208, will reflect less IR light back to digital video camera 216 than those tabletop devices 206 positioned in contact with display surface 208. Video camera 216 senses IR light reflected from tabletop objects 206 within its imaging field and produces a digital signal corresponding to images of the reflected IR light. The digital signal is input to processor 202 to enable a location of each tabletop device 206 to be determined. In addition, the size, orientation, and shape of tabletop device 206 may also be determined. Moreover, and as described in greater detail below, a tabletop device 206 may include an IR light reflective pattern or coded identifier that uniquely identifies that particular tabletop device 206 and/or identifies the tabletop device 206 as being within a particular class or group of related tabletop devices 206. Accordingly, the digital signal produced by video camera 216 may also be used to identify a tabletop device 206.
In one embodiment, processor 202 is integral to table 200. In an alternative embodiment, processor 202 is external to table 200 as part of, for example, a server (not shown). As used herein, the term “processor” may include any programmable system including systems using microcontrollers, reduced instruction set circuits (RISC), application specific integrated circuits (ASICs), logic circuits, and any other circuit or processor capable of executing the functions described herein. The above examples are exemplary only, and are thus not intended to limit in any way the definition and/or meaning of the term “processor”. In the exemplary embodiment, processor 202 executes algorithms for processing the digital signal from digital video camera 216 and executes software applications that use a user interface functionality of table 200 to display graphic images. The graphic images include, for example, but are not limited to only including, pictures and/or a virtual environment that is visible on display surface 208. As such, table 200 also includes a video projector 222 that displays graphic images, a virtual environment, and/or text information on display surface 208. In one embodiment, video projector 222 is a liquid crystal display (LCD). In an alternative embodiment, video projector 222 is a digital light processor (DLP) display. To facilitate preventing IR light emitted by video projector 222 from entering table 200, wherein the IR light may interfere with the IR light reflected from tabletop devices 206, a filter, such as an IR cut filter 224, is positioned in front of a projector lens (not shown) of video projector 222.
Moreover, in one embodiment, table 200 also includes a plurality of mirror assemblies 236. Specifically, in the exemplary embodiment, a first mirror assembly 226 directs light projected from video projector 222 through an opening 228 defined in frame 204 such that the projected light is incident on a second mirror assembly 230. Second mirror assembly 230 reflects the projected light onto translucent layer 214, which is positioned at a focal point of video projector 222. Table 200 also includes at least one alignment device 232, which is sized to facilitate properly aligning first mirror assembly 226. A positioning device 234 adjusts an angle of second mirror assembly 230. Such devices 232 and 234 facilitate ensuring that the image projected onto display surface 208 is properly aligned with respect to display surface 208. Alternative embodiments may include alternate elements that may be used to align first and second mirror assemblies 226 and 230. Moreover, other alternative embodiments may not include mirror assemblies 236 and/or devices 232 and 234 but, rather, directly project light from video projector 222 onto display surface 208.
In the exemplary embodiment, wheel 302 includes a top surface 330, an opposing bottom surface 332, a first flange 334, and an opposite second flange 336. First and second flanges 334 and 336 are positioned between top surface 320 of base first portion 308 and bottom surface 314 of base second portion 310. More specifically, in the exemplary embodiment, first and second flanges 334 and 336 are positioned such that wheel 304 is rotatable about axis A-A with respect to base 302. In the exemplary embodiment, wheel 304 is formed from a clear acrylic material. Moreover, in the exemplary embodiment, wheel 304 includes an object tag 338 that is coupled to wheel bottom surface 332 in an orientation that enables object tag 338 to be read by video camera 216 (shown in
In another alternative embodiment, wheel 304 includes an encoder ring (not shown). In such an embodiment, base second portion 310 includes a light-emitting diode (LED) (not shown) oriented such that light is emitted towards base first portion 308. Moreover, in such an embodiment, base first portion 308 includes a detector (not shown) that detects light emitted by the LED. The detector determines an angle of rotation of wheel 304 that corresponds to a position of wheel 304. Alternatively, base first portion 308 may include an LED that is oriented to emit light towards base second portion 310, and base second portion 310 may include the detector.
In the exemplary embodiment, display 306 is formed integrally with wheel top surface 330. More specifically, display 306 displays an image to a player that corresponds to a position of wheel 304. In one embodiment, the image is generated by video projector 222 (shown in
In one embodiment, device 300 includes a force feedback device (not shown) that provides feedback, such as haptic feed back and/or audible feedback, to a player as the player rotates wheel 304. For example, for each of unit of rotation, the force feedback device will emit a sound, such as a click sound, and will provide to the player a sensation of resistance and/or tumbler detents associated with locks. The force feedback device may also determine an angle of rotation of wheel 304 by incrementing a count of units of rotation that the player imparts to wheel 304. The force feedback device may be implemented using, for example and not by way of limitation, a PR1000 rotary actuator commercially available from Immersion Corporation, San Jose, Calif.
In an alternative embodiment, device 300 includes a transceiver (not shown). The transceiver communicates with a processor, such as processor 202 (shown in
In another alternative embodiment, device 300 includes a battery (not shown).

During operation, in the exemplary embodiment, a player rotates wheel 304 about axis A-A to a selected position by aligning pointer 328 with a selected marking 326 on base third portion 322. In one embodiment, the player then depresses wheel top surface 330 to cause contact between the electrical contacts on bottom surface 340 of first flange 334 and/or second flange 336 and top surface 320 of base first portion 308. The selected position is then stored in a memory and/or transmitted using a transceiver to a processor, such as processor 202. A combination of position selections by the player may correspond to an award. Processor 202 determines the award and transmits an image or an image identifier to the transceiver. An image associated with the position of wheel 304 and/or combination of positions of wheel 304 is then displayed to the player via display 306. In an alternative embodiment, when the player depresses wheel top surface 330, object tag 338 is moved into a position such that object tag 338 is readable by video camera 216, which transmits the position associated with object tag 338 to processor 202. Processor 202 determines the award and causes video projector 222 to project an image through wheel 304 such that the image associated with the position of wheel 304 and/or combination of positions of wheel 304 is displayed to the player via display 306.
In another alternative embodiment, as the player rotates wheel 304, a detector determines an angle of rotation of wheel 304 based on a number of units of rotation. The number of units of rotation is based on a number of LED light emissions counted by the detector and/or shaded by an encoder ring. The angle of rotation is then stored in a memory and/or transmitted using a transceiver to a processor, such as processor 202, and processor 202 determines a position associated with the angle of rotation. A combination of position selections by the player may correspond to an award. Processor 202 determines the award and transmits an image or an image identifier to the transceiver. An image associated with the position of wheel 304 and/or combination of positions of wheel 304 is then displayed to the player via display 306.
In yet another embodiment, a force feedback device (not shown) is coupled to wheel 304 in order to provide haptic and/or aural feedback to the player as the player rotates wheel 304. The force feedback device may also be configured to determine an angle of rotation of wheel 304 based on a number of units of rotation. The number of units of rotation is counted by the force feedback detector and the angle of rotation is then stored in a memory and/or transmitted using a transceiver to a processor, such as processor 202. Processor 202 then determines a position associated with the angle of rotation. A combination of position selections by the player may correspond to an award. Processor 202 determines the award and transmits an image or an image identifier to the transceiver. An image associated with the position of wheel 304 and/or combination of positions of wheel 304 is then displayed to the player via display 306.
In the exemplary embodiment, wheel 404 includes a top surface 422, a bottom surface 424, and a plurality of segments 426. A current position of wheel 404 is communicated to the player according to a particular segment 426 being aligned with pointer 418. Moreover, wheel 404 is coupled, such as rotatably coupled, to base 402. In the exemplary embodiment, each segment 426 includes a display 428. More specifically, display 428 displays an image to a player that corresponds to a position of wheel 404. In one embodiment, the image is generated by video projector 222 (shown in
