[0004] This application is also related to co-pending U.S. Patent Application No. 12/271,781, entitled GAMING MACHINE HAVING A CURVED DISPLAY and U.S. Patent Application No. 12/271,802, entitled GAMING MACHINE HAVING A CURVED DISPLAY AND RELATED GAMING SYSTEMS, both filed on November 10, 2008, which is hereby incorporated by reference.

BACKGROUND

[0005] Gaming machines have been developed having various features to capture and maintain player interest. Some features are directed to increasing or providing the player with the opportunity to win larger sums of money. For example, gaming machines may include second chance games that provide a player with additional opportunities to obtain a winning outcome. Alternatively, gaming machines may be tied into progressive gaming systems that award large progressive jackpots.

[0006] In addition to providing players with more opportunities to obtain a winning outcome or win a large sum of money, gaming machines have increased the number of features and grown in sophistication in order to increase player participation or interest in a game. For example, the mechanical reels of traditional gaming machines have been replaced with video depictions of spinning reels. These video gaming machines provide a richer gaming experience for players by including graphics or animation as part of the game. However, overly complex video displays on a gaming machine may turn off player participation because players become frustrated with the game or are unwilling to learn or decipher all the information provided on the video display. Accordingly, there is a continuing need for slot machines variants that provide a player with enhanced excitement without departing from the original slot machine gaming concept.

DETAILED DESCRIPTION

[0032] Various embodiments are directed to gaming machines having video depictions of one or more mechanical reels projected onto a curved display. According to one embodiment, a digital light processing (DLP) projector that presents video images of one or more reels on the curved display. In one embodiment, the curved display is shaped to simulate the look of mechanical reels. Additionally, the high resolution of the DLP projector presents video images that give a player the impression that the combination of the curved display and the video images are physical, mechanical reel strips.

[0033] In other embodiments, shrouds (either physical or video-depictions of the shrouds) may be placed between the video depiction of the reels to provide a more realistic impression of mechanical reels. Optionally, the gaming machines may include other audio and visual features to enhance the perception that the video images and curved display are mechanical reels. For example, the video images may shudder to simulate the torque of stopping the spinning mechanical reels. Alternatively, the video images may have visual imperfections to simulate mechanical reels. Furthermore, audio sound effects may be coordinated with the movement and stopping of the reels to further simulate a gaming machine having mechanical reels.

[0034] Because the gaming machine is video-based, the gaming machine also maintains the flexibility of a video gaming machine. For example, the DLP projector may present pay lines directly on and/or around the symbols that comprise a winning outcome. The pay lines may be animated or otherwise highlight the winning combination of symbols. Optionally, the winning symbols may be animated on the "virtual" reel strip. For example, the symbols that form a winning pay line may interact with one another or the symbols may be emphasized by expanding the size of the symbol. Alternatively, a short animated movie may be presented at one or more of the game indicia on a winning pay line. In another embodiment, the images of the game indicia on the "virtual" strips may be altered so that a "wild" symbol morphs into the game indicia that forms a winning combination. For example, a "wild" symbol may morph into a "7" to complete a winning combination of "7-7-7." In yet another embodiment, the reel strip color may be altered in response to a particular game outcome or trigger for a bonus game.

[0035] Referring now to the drawings, wherein like reference numerals denote like or corresponding parts throughout the drawings and, more particularly to FIGS. 1-18, there are shown various embodiments of a gaming machine having a curved display system. More specifically, as shown in FIG. 1, the gaming machine 10 includes a curved material 12 positioned within the main gaming cabinet 14. A video image 16 of one or more mechanical reels is projected onto the curved material 12 by a digital light projection (DLP) device 18 or other light projection system. As shown in FIG. 1, the video image 16 depicts an image of three mechanical reels. In another embodiment, the video image 16 may depict video images of five mechanical reels.

[0036] It is contemplated that the video image 16 may present any number of reels ranging from one reel to five or more reels. In another embodiment, the gaming machine may include a combination of one or more mechanical reels and video images of one or more reels presented on a curved display. The DLP device may project one or more video images 16 onto the curved display 12. Accordingly, it is possible to present a game that is a combination of mechanical reels as well as video reels. The video reels may be part of the primary game or may be presented as a portion of a secondary game.

[0037] As shown in FIG. 1, the video image 16 of each of reels also presents one or more game indicia 28. Optionally, the game indicia 28 may be animated when the indicia 28 is a component of a winning outcome on an active pay line. Alternatively, the game indicia 28 morphs into a symbol that forms a winning outcome. For example, a "wild" symbol will morph (i.e., change into) a symbol that will form a winning outcome. Accordingly, for a winning outcome of "cherry-wild-cherry," the "wild" symbol will change into a "cherry" symbol.

[0038] FIG. 2 illustrates a schematic diagram of the components of one embodiment of a gaming machine 10 having a curved display system. The gaming machine 10 includes a microcontroller with a central processing unit (CPU) 32 one or more video outputs 34, and a system memory (not shown). The CPU 32 is in communication with a LCD and DLP control driver 36 via video outputs 34. As shown in FIG. 3, the LCD and DLP control drivers 36 are integral components. In other embodiments, it is contemplated that the LCD and DLP control drivers are separate components. The LCD control driver 36 interfaces with primary LCD display 38 and the secondary LCD display 24 via a mixer 42. In another embodiment, the LCD control driver 36 may directly interface with the primary 38 and secondary displays 24.

[0039] The primary LCD display 38 may be used to display buttons and lights, pay line indicators, and other game information such as, but not limited to, credits available, credits won, wager size, wager per pay line, or wager denomination. The secondary LCD display 24 may be used to display other game related information such as, but not limited to, one or more bonus games, pay tables, game theme information, jackpot information, progressive jackpot information jackpot meters, or the like. The secondary LCD 24 may also display non-gaming related information such as, but not limited to, player account information, advertisements, casino promotions, news, one or more sporting events, or the like.

[0040] FIGS. 3-5 illustrate exploded views of various embodiments of a curved display system 50. The curved display system 50 is described by relating the components of the curved display system in relation to layers with the outermost layer in front of the gaming cabinet 14 (i.e., outer layer is closest to the game patron) and the innermost layer located within the gaming cabinet.

[0041] As shown in FIG. 3, the outermost layer of a transparent material. The transparent material 52 may be flush with the gaming cabinet 14 or slightly recessed within the gaming cabinet. In one embodiment, the transparent material 52 may be one or more layers of glass, polycarbonate, plexiglass, or other transparent material known or developed in the art. The transparent material may also include printed graphics or a printed frame around the perimeter of the transparent material. In another embodiment, the transparent material 52 may be one or more LCD displays. In yet another embodiment, the transparent material 52 or the LCD displays may also include a touch screen system 54, as shown in FIG. 5.

[0042] Referring to FIG. 3, one more shrouds 56 are placed in front of the curved material 12. The shrouds are physical pieces of material positioned in front of the curved material. The shrouds 56 are placed between the images of the reels 16 that are projected onto the curved material 12 and give the player the impression of separate reel strips. The shrouds 56 may be placed directly on the curved material 12. In another embodiment, the shrouds 56 may be positioned between the transparent material 52 and the curved material 12. In yet another embodiment, the shrouds 56 are placed on the transparent material 52. In another embodiment, the shrouds are video images that are placed between the video images of the reels.

[0043] As shown in FIGS. 3-5, a curved material 12 is positioned behind the transparent material 52. In one embodiment, a portion of the curved material 12 touches the transparent material 52. Alternatively, the curved material 12 is in spaced relation to the transparent material 52. The curved material 12 is made of a material that is optically clear such as, but not limited to, glass, polycarbonate, plexiglass, acrylic, or the like. The curved material 12 has a radius of curvature similar to the radius of curvature of a mechanical reel. According to one embodiment, the radius of curvature is approximately 4.5". However, as those skilled in the art will appreciate, the curved material may have any radius of curvature that approximates or simulates the appearance of a mechanical reel. A shown in FIG. 3, the curved material 12 is a single piece of material. In another embodiment, two or more pieces of a curved material may be used to form a curved display. In one embodiment, the pieces may be slightly spaced apart to give the appearance of separate reels.

[0044] As shown in FIG. 3, glossy coating 58 is applied to the outer surface of the curved material 12. In another embodiment, the outer surface of the curved material 12 is polished to a finish having a glossy or reflective properties. The glossy finish reflects light to further to simulate or mimic a mechanical reel. Optionally, a finish or coating 58 may be applied to the inner surface of the curved material to improve the appearance of the images projected on the inner surface, as shown in FIG. 3.

[0045] As shown in FIGS. 3-5, a DLP device 18 is positioned behind the curved material 12. The DLP device 18 projects video images onto the inner surface of the curved material 12. The DLP device 18 generally includes a DLP chip, a flywheel color filter, and a light source. In one embodiment, the light source is a high intensity discharge (HID) projector. In another embodiment, the light source is a light emitting diode (LED) projector.

[0046] The DLP device 18 may directly project video images onto the inner surface of the curved material 12 as shown in FIGS. 3 and 5. Alternatively, the video image is indirectly projected onto the inner surface of the curved material by reflecting the video images off a mirror 62, as shown in FIG. 4. In one embodiment, the DLP device 18 projects an image having a display resolution of 800 x 600, 1280 x 720, 1280 x 1024, or 1980 x 1080. As those skilled in the art will appreciate, these resolution values may be approximate as the resolution may be lower or higher than the cited resolution values. For example, the DLP device 18 may project an image of a plurality of reels onto the curved material having a resolution of 1360 x 768.

[0047] As shown in FIGS. 3-5, a lens 60 is positioned between the curved material and the DLP device 18. In one embodiment, the lens 60 may be an anamorphic lens may be used shorten or stretch the image to an appropriate size. In other embodiments, a video scaler or other software may be used to reduce or increase the size of the image in order for the image to fit within the curved display. In another embodiment, the larger image may still projected (i.e., overscan) onto the curved material, but the extra image that is over-projected is not visible to the game patron as a screen or other partition is used to block out the periphery of the curved material. In some embodiments, the edges of the projected image are bowed/distorted, thereby create a fish-eye effect. This effect may be corrected using warping software and/or hardware to correct the projected image. In another embodiment, a warping template, which is previously created for a particular hardware configuration, may be applied to correct the projected image.

[0048] FIG. 4 illustrates a curved display system 50 in which the image of the reels is indirectly projected onto the curved material 12. The curved display system 50 includes a short-throw lens 60 and a front-coated mirror 62 to achieve the necessary image size while working with the dimensional constraints (i.e., depth) of the gaming cabinet 14. Otherwise stated, the DLP device 18 requires a particular throw distance in order to project a particular image size, but the gaming cabinet 14 is not large enough to accommodate such a throw distance. For example, according to one embodiment, the combination of the short-throw lens 60 and the front-coated mirror 62 provides a throw distance of approximately 25".

[0049] In alternate embodiments, a combination of a short-throw lens 60 and a back-coated mirror may be used to achieve the proper throw distance for the DLP device 18. In another embodiment, a combination of a short throw-lens and two or more mirrors may be used to achieve the proper throw distance. In yet another embodiment, the gaming cabinet (not shown) is sized to allow the DLP device 18 to directly project an image onto the curved display 12 without needing a short-throw lens and/or any mirrors.

[0050] FIG. 5 illustrates another embodiment of a curved display system 50 having a touch screen 54 placed in front of the curved display 12. As shown in FIG. 5, the touch screen 54 is a flat surface that is spaced apart from the curved display 12, as disclosed in U.S. Patent Application No. 11/209,895, filed August 23, 2005, which is hereby incorporated by reference. In another embodiment, the touch screen 54 is curved to conform to or approximately conform to the shape of the curved display.

[0051] FIGS. 6-8 illustrate one embodiment of a touch sensor assembly 68 incorporating a substantially transparent touch panel 54, a touch controller 70, and touch panel software. As shown in FIG. 6, the touch panel 54 utilizes the touch sensor assembly 68 to produce touch data when touched or activated, as well as allowing substantially unobstructed viewing of the projected images of the reels shown on the curved display 12 behind the touch panel. The touch sensor assembly 68 includes one or more touch pad areas (not shown), one or more touch transducers 66, wave reflectors (not shown), cabling (not shown), a bezel (not shown), a touch panel controller 70, touch panel driver software, and touch panel application software. The material for the touch pad areas (not shown), is either glass or other polymeric material suitable for propagating surface acoustic waves.

[0052] Additionally, the transducers 66 are able to adhere to the skin of the glass-like materials of the touch panel 54 sufficiently to pass around curves. This allows a curved touch panel (not shown) to be utilized without detrimental effects. Accordingly, in one embodiment, the touch panel 54 has a radius of curvature similar to the curved display 12. Also, one of ordinary skill in the art will appreciate that while the touch panel 54 is shown to be rectangular in shape with respect to FIG. 6, the touch panel may be designed to accommodate the shape of any gaming machine configuration (e.g., circle, semi-circle, triangle, and the like).

[0053] As shown in FIG. 7, the touch panel 54 is placed in front the projected images of the reels 16. Touch panel data received by the touch panel 54 is transmitted to the touch panel controller. The touch panel controller 70 acts to control and interpret touch data from the touch panel 54. The controller 70 typically includes a printed circuit board assembly, often encased inside a metal or plastic housing with mounting holes. In one embodiment, the controller 70 is mounted to the inside of the gaming machine door or cabinet, and is preferably within reach of the touch panel wiring (not shown). The controller 70 is wired to the appropriate power and communication connections within the gaming machine. The controller 70 outputs a data stream consisting of touch coordinate information.

[0054] In one embodiment, the microprocessor 72 runs an application that translates the touch panel controller 70 serial touch information into reel control commands for the GDCU reel controller 74. The application uses drivers to communicate with the GDCU 74 which controls the projection of the image onto the curved display 12. The GDCU 74 is a communications portion of the gaming machine 10 which "talks" to the different components of the gaming machine.

[0055] FIG. 8 illustrates the operational flow of a gaming machine including a touch panel system. As shown in FIG. 8, the logical operations of the various embodiments of the touch screen system are implemented (1) as a sequence of computer implemented steps or program modules running on a computing system and/or (2) as interconnected machine logic circuits or circuit modules within the computing system. The implementation is a matter of choice dependent on the performance requirements of the computing system implementing the touch panel system. Accordingly, the logical operations making up the embodiments of the touch panel system described herein are referred to variously as operations, structural devices, acts or modules. It will be recognized by one skilled in the art that these operations, structural devices, acts and modules may be implemented in the system, in firmware, in special purpose logic, analog circuitry, or any combination thereof.

[0056] As shown in FIG. 8, the logical operations of a touch panel system 64 utilize the components of the system in a logical sequence. In the panel activation step 80, the touch panel 54 is activated. This occurrence produces a signal that is received by the transducers 66 associated with the touch panel 54 in the transducer signaling step 82. In the controller signaling step 84, a signal is sent to the touch panel controller 70 reporting the activation of the touch panel 54. From the touch panel controller 70, a signal is then sent to, and interpreted by, the touch panel software (which is in the microprocessor 70) in the signal processing step 86. Finally, the touch panel software sends a signal to the GDCU reel controller 74 to activate the DLP device 18 in the mechanical activation step 88.

[0057] The touch panel system 64 is adapted to detect and interpret different types of touch data. For example, FIGS. 9A-9B illustrate one embodiment in which touch data in the form of a touch gesture 90 generally parallel to the reels will cause the projected image of the reels to spin. The touch gesture in a "slide up" or "slide down" motion will initiate the spinning of the reels as shown in FIG. 9B. The gesture causes the reels to spin in the particular direction of the gesture. For example, if the gesture moves top-down on the touch screen, the reels spin in a top-down direction. Alternatively, if the gesture moves bottom-up on the touch screen, the reels spin in a bottom-up direction. Additionally, the speed of the gesture may effect the speed of the spinning of the reels. For example, if the gesture is fast, the reels spin fast whereas the reels will spin slower for a slower gesture. Generally, any gesture on the touch screen that is parallel to the image of the reels will cause all the reels to spin. In another embodiment, the player needs to make a gesture at a particular area adjacent to the image of the reels in order to cause the image of the reels to spin. In yet another embodiment, the player can gesture to control each reel. Accordingly, the player may vary the order and/or speed of each reel spun.

[0058] FIGS. 10A-10B illustrate touch gestures related to placing a wager or selecting a pay line. For example, in one embodiment, touch data sensed at the location near a pay line will result in the selection of the pay line for play. If the touch data is a circular motion 91 that covers one or more paylines 92, this touch gesture is interpreted as selecting two or more pay lines, as shown in FIG. 10A. For example, the circular gesture encompasses or touches all pay lines, then all the pay lines are selected. Alternatively, if the circular gesture only encompasses three pay lines, those three pay lines are selected for play. As shown in FIG. 10B, the pay lines located within the touch gesture are highlighted on the screen and active for game play.

[0059] FIGS. 11A-11C illustrate various screen shots of touch gestures that add or remove reels from the game. A generally-perpendicular, touch gesture 93 in a direction away from the reels is interpreted as a player request to remove reels. FIG. 11A shows a five-reel game and a player touch gesture 93 (away from the reels toward the edge of the screen). As a result, two reels are removed from the game, and the curved display projects an image of a three-reel game as shown in FIG. 11B. According to one embodiment, each generally perpendicular touch gesture in a direction away from the reels causes one reel to be removed. In another embodiment, each generally perpendicular touch gesture causes a predetermined number of reels (e.g., two reels) to be removed from the game. As those skilled in the art will appreciate, the game is configured to have a predetermined minimum number of reels for a particular game.

[0060] As shown in FIG. 11B, a generally-perpendicular touch gesture 94 from the edge/side of the curved display toward the center of the display causes one or more reels to be added to the game. As shown in FIG. 11C, the touch gesture 94 of FIG. 11B causes one reel to be added to the game to form a four-reel game. A gesture 93, 94 may be programmed to add one reel or add a predefined group of reels (e.g., two, three, or more reels per gesture).

[0061] FIGS. 12A-12B illustrate another embodiment of touch gestures 95 that allow a player to move symbols 28 between reels 16. As shown in FIG. 12A, the gesture is touching the positions on the touch screen corresponding to two game indicia (e.g., with the thumb and middle finger) and drawing the thumb and middle finger together. This gesture will cause two symbols to swap positions on the reels as shown in FIG. 12B.

[0062] As shown in FIGS. 12A-12B, a player is able to swap symbols between adjacent reels. Alternatively, the player may be able to swap symbols between non-adjacent reels. In another embodiment, the touch data may be a gesture that allows a player to change the order of symbols on the same reel. In one embodiment, only adjacent symbols on the same reel may be swapped. Alternatively, any symbols on the same reel may be swapped. The touch screen may be activated during certain portions of a game to allow a player to swap symbols. For example, the touch screen may be activated for a predetermined period of time after a game has completed. Accordingly, a player may attempt to achieve a winning outcome or improve a winning outcome by swapping symbols.

[0063] In various embodiments, the ability to swap symbols may be a feature of the game or the player must have satisfied some predefined criteria to permit this feature of the game. For example, the predefined criteria may be one or more maximum wagers, a predefined period of continuous play, a particular player club level, accrual of a particular number of player club points, or any other trigger events known or developed in the art. As those skilled in the art will appreciate, the game may be limited to only allow the player to swap certain game indicia. Alternatively, the game may allow any swapping of game indicia between reels or on the same reel. Optionally, the game may allow more than one swap per game.

[0064] In yet another embodiment, the touch screen is configured to accept touch data that allows a player to add a game indicia onto one or more reels or remove one or more indicia from a reel as shown in FIGS. 13A-13D. FIG. 13A illustrate one embodiment in which a touch gesture 96 from a game indicia 28 on one of the reels to a symbol bank 97 causes the game indicia to be moved from the reel to the symbol bank as shown in FIG. 13B. FIG. 13C illustrates one embodiment in which a touch gesture 98 from a symbol bank 97 to a reel 16 causes a game indicia 28 to be added to a reel at the position in which the touch gesture terminates, as shown in FIG. 13D.
