FIELD OF THE INVENTION The present invention related generally to a system and method of obscuring or partially obscuring an electronic playing card.

BACKGROUND OF THE INVENTION Gaming is an increasingly popular form of entertainment. Games, particularly, games of change and skill in which one or more players play and place wagers on the outcome thereof may be played in a variety of ways, including at a casino or other venue or on the Internet. Of the various forms of games which are available for play, many are played with playing cards. Of these, poker is arguably the most popular.

Traditionally, poker is played at a table with several players wagering paper or coin money on a series of playing cards dealt from a deck of fifty-two cards. This deck is comprised of four suits at thirteen cards per suit. This form of poker requires a human dealer to coordinate the game, including dealing, wagering, folding, One of the problems with traditional poker is that it suffers from the possibility of human/dealer N:\Melboure\Cases\Patent\76000-769919\P76492.AU.2\Specis\P76492 AU.2 Spccificaion 2008-2-5.doc 08/05 2008 13:31 FAX 61 3 92438333 GRIFFITH HACK [a005 -3error. In "social" card games, especially poker, the players take turns acting as the Odealer, but in licensed commercial gaming establishments, such as casinos, the dealer is typically a non-playing employee. Thus, another problem associated with traditional poker games in this context is the training and retention of de4lers.

s One alternative form of gaming, with particular refereAce to poker, has 0flourished on the internet. Internet gaming has become quite s ccessful in that it 0 provides many choices for the players. In particular, Internet 4aming is fast and convenient, with registration, betting and payouts available frcm almost any computer with Internet access and with payments typically arranged via a credit card or electronically.

Poker or other card games may also be provided by stakd-alone machines 0similar to slot machines, OOne major drawback of internet and stand-alone type glames is the lack of the ,O human element. Many people prefer to play poker against othjr players, due in part to the drama associated with "live" gaming. Undoubtedly, an ele{'ated level of competition exists when humans compete directly against one another. In aming establishments, experienced players are trying to hone strategy and read other players' intentions through their movements and style of play to be more competi ive.

Electronic card games, such as electronic poker games,jhave been provided which allow players to compete against one another, but elimi4ate the dealer and the physical cards. However, one problem associated with electror ic cards is maintaining the confidentiality of each player's cards which are typically di.played on a monitor in close proximity to the player. In general, the prior art deals wi h this problem by providing some type of shield or other physical barrier. Howetr, these type of devices have several inherent problems, in that they are easy to defeat 6y positioning oneself where the player's card are viewable. Furthermore, the devices have not been well received by players. Additionally, these devices are bulky and lend to extend upward from the monitor. This detracts from the overall appearance ofhe environment and may distract the players.

The present invention is aimed at one or more of the problems set forth above.

In the illustrated embodiment, the poker tables 18 are able to seat a maximum of ten players at a time, and thus, includes ten electronic player interaction areas 24A-24J. The table top 10 also includes a central or common display area (CDA) 26.

In one embodiment, the individual electronic player interaction areas 24A-24J are used to convey game information directly to a player assigned to a specific player interaction area 24A-24J and to implement a player user interface (see below) to effectuate interaction or input from the player. The central or common display area 26 is used to display information to all off the players.

For example in one embodiment, the system 10 is used to play the version of poker known as Texas Hold'em. In Texas Hold'em, each player is dealt a number of cards, two cards, face down. These are know~n as a player's "hole" cards 28. A number of cards ar~e dealt face-up and displayed in the common display area 26. These are known as the common cards 28. A player's hand, thus, consists of the player's hole cards 28 and the common cards 28. Whichever player's hand makes the highest poker hand is the winner of that round or hand of poker.

In one aspect of the present invention, the hole cards 28 are displayed facedown on the respective electronic player interaction area 24 and the common cards are displayed in the central display area 26. The hole cards 28 are displayed at a first predetermined ratio and the common cards 28 are displayed at a second predetermined ratio. The first and second predetermined ratios may be expressed as a ratio of a standard N-\Mclb,me\Caucs\Patent\76000-76999\P76492.AU.2\Specis\P76492 AU.2 Specification 2008-2-5.doc -9size playing card or a predetermined default size. In one embodiment, the first and 0 0 different For example, the first and second ratios may be defined such that the common cards 28 are displayed larger than the hole cards 28.

With reference to Figures 6, 7, and 8 in one embodiment, the electronic player ci interaction areas 24 are implemented using separate display devices, such as touchscreen displays 32. Each display 32 may be housed in a removable module 34.

Other information which may be displayed on the player interface include, but is not limited to indicator of the player whose turn it is, a total of chips for each player, any cards of the other players which arc face-up, and/or messages to the player, such as advertising.

V. System and Method or Dislaying and/or Obscuring Electronic Playing Cards In another aspect of the present invention, the player interface 54 includes a graphical representation of one or more of electronic playing cards 76 (see Figure 12).

N:\Melibourm\Cases\Patent\760DO-76999\P76492.AU.2\Specis\P76492.AU.2 Spci~fication 2008-2-S.doc 13 Each electronic playing card 76 has a front side 76A and a back side 76B. The back 00 0 side 76B of each card has an identical pattern or image such that the cards cannot be told c-I apart when viewing the back side 76B. The electronic playing card 76 is typically one of a set or deck of standard playing cards. The deck may be a standard deck of 52 cards, each card having a value. The value being two components: the first component being NI one of a two through ACE and the second component being one of four suits (hears, diamonds, clubs, spades). The value of each card is indicated on the front side 76A of kn each playing card 76.

The image displayed on the back side 76B of the playing cards may be a logo, a random image (chosen from a set of predetermined images), or may be advertising 00 directed at the player. The image may include a video. In one embodiment, the image Cl displayed on the back side 76B of the playing cards may be cycled through a set of predetermined images. The image may be selectable by a user, who may be the player or an employee of the casino.

In one embodiment the electronic playing card or cards 76 are a player's hole card(s) in an electronic poker game. However, the electronic playing 76 cards mpiy be used in any sort of electronic card game in which it is desirable to controllably display/hide the player's cards. Thus, while the present invention may be described below in the context of an electronic poker game (and more specifically, with respect to a player's hole cards in a Hold'em. style poker game), the present invention is not limited to such a card game.

In a playing card game with physical cards, in which the player's card are dealt "face-down" and not revealed to any other player, the player may look at their cards, while attempting to keep the cards secret from the other players in several ways. For example, the player may lift the cards close to their bodies, spread them out, and shield them with their hands, so only the player can see the front side of their cards. Or the player may leave the cards face down on the table and lift one side or cornier revealing at least a portion of the fr-ont side, while shielding the cards with their bands.

A controller, which is either, the module 34, the personal computer 52, the hand-held device 58, the server 50 or a combination thereof, controls the player interface 54, controls the information components of the player interface 54 displayed on the electronic player interaction areas 24, detects touches on the touch screen display devices N \Melbourne\Cases\Patent\76000-76999J76492AU.2\Specis\P76492.AU.2 Specification 2008-2-S5doc 14 00 32 (when utilized) and interprets the touches as trigger or touch events (see below). As discussed below, the controller 24, 52, 58, 50 may control the display or obscuring (hiding) of the player's hole electronic playing card(s) such that the player may controllably display and view the cards, while maintaining them secret from the other players. As if the player was playing with physical playing cards, the player, thus, has the opportunity to shield their cards with their hand or hands prior to them being revealed.

In one aspect of the present invention, the controller 24, 52, 58, 50 detects a trigger event and displays at least a portion of the front side 76A of the hole electronic 00 playing card or cards 76 in response to the trigger event. The back side 76B of the hole electronic playing card or cards 76 are displayed on the electronic player interaction area 24, the hole electronic playing card or cards 76 are displayed face-down. The electronic player interaction area 24 is implemented on the touch-screen display device 32. In one embodiment, the trigger event is defined as a touch event on the touch-screen display device 32.

In one aspect of the present invention, the touch event may be defined by several parameters. For example, the touch event may require that the player touches a pre-defined location (indicated for purposes of illustration only by a dotted lie) on the touch-screen display device 3 2 for a predetermined period of time. As shown in Figures 9 and 10, the predefined location may be indicated on the touch-screen display device 32 by a gra phic or icon 80. In the illustrated embodiment, the graphic 80 includes the phrase "PRESS HERE TO REVEAL HOLE CARDS", but other words and/or graphics may be used. Alternatively, the touch event may be defined by two or more predetermined locations 78 on the touch-screen display device 32.

In another embodiment, the touch event may be defined as actuation of a mechanical switch/button (not shown).

In one embodiment, the at least a portion of the front side 76A of the hole electronic playing card 76 may be displayed, after the occurrence of the trigger event, for a predetermined time period, 2 seconds. Alternatively, the fr-ont side 76A of thc hole electronic playing card 76 may be displayed until the trigger event has been removed. In this case where the trigger event is a touch event, the front side 76 of the N \Melbourne\Cases~atent\76000-76999\P76492.AU.2\Specis\P76492.AU.2 Specification 20D8-2-.doc 15 hole electronic playing card 76 is, thus, displayed until the player stops touching the 00 predetermined location.

N ~With reference to Figure 8, the electronic player interaction areas 24 include a* hand rest 82. The hand rest 82 is located in a location relative to the touchscreen device 32 which guides a hand of the player towards the predetermined location 78. The hand ri rest 82 may be in either or both sides of the device 32 and may be implemented as an indentation.

In another aspect of the present invention, the controller 24, 52, 58, 50 for allowing the player to designate a location where the hole electronic playing card or cards 76 are to be displayed on the touch-screen video display 34. For example, as 00 shown in Figures 9 and 10, the hole electronic playing cards 76 are located adjacent a right side of the touch-screen video display 34. However, some players such as lefthanded players, may prefer that the hole electronic playing cards 76 be located on the left side of the touch-screen video display 34. Additionally, other players may prefer that the hole electronic playing cards 76 are located in the center of the touch-screen display device 34. In one embodiment, the locations at which the hole electronic playing cards are displayed may be predetermined. The player may select between these predetermined locations through a menu accessible through the options button 72C. In another embodiment, the player may set the position by touching an area on the touchscreen display device 34. This feature may also be accessible through the options button 72C.

With reference to Figures 13-22 several methods for displaying or otherwise indicating the value of the hiole electron-ic playing cards 76.
