     BACKGROUND 
     1. Field of the Invention 
     The present invention relates to a player interface associated with an electronic gaming device and, more particularly, to such an interface that includes a display and an input device to provide interactive communication with the player. 
     2. Background of the Invention 
     Incorporating casino slot machines into a computer network is well known. Early in the deployment of such networks, preexisting slot machines were retrofitted by installing a communications board that included a processor, memory and other components that facilitated communications between the electronic slot machine and the network. When so configured, transactions at one of slot machines could be communicated via the board onto the network and from there to a computer that stored the transactions for later analysis and verification. Conversely, the network computer can issue commands onto the network that are addressed to a particular machine or a group of machines. The communications board receives the command and communicates with the slot machine to effect, for example, payment of a bonus over and above the pay table in the slot machine as described in U.S. Pat. No. 5,655,961, which is owned by the assignee of the present application and which is incorporated herein by reference for all purposes. 
     In addition to the communications board, it is well known to install a card reader, a display, and a keypad at each slot machine to facilitate player tracking, as it is referred to in the industry. In a conventional player-tracking system, each player is assigned a card and an associated account, which is maintained on a network computer. Before playing one of the slot machines, the player inserts his or her card to cause points proportionate to play to accrue in his or her account. The points are then redeemable by the player for additional play, dinners, merchandise, or the like. In addition, the card, keypad and display, which is typically a vacuum fluorescent display or a small-character LCD display, can be used to permit a player to access a cashless play account or to access credits that are either complimentary or awarded to the player during the course of his or her play. 
     The design, construction and operation of networked slot machines, including the card reader, the keypad and the display, as mentioned above, is described in detail in the &#39;961 patent. Another embodiment is also described in U.S. Pat. No. 6,319,125 for a Method and Apparatus for Promoting Play on a Network of Gaming Devices, which is also assigned to the assignee of the present application and which is also incorporated herein by reference for all purposes. 
     In addition to player-tracking functions, cashless play and associated functions can be implemented using the system of  FIG. 1  as described in U.S. patent application Ser. No. 09/694,065, which is assigned to the assignee of the present application and which is incorporated herein by reference for all purposes. In addition, conversion of player-tracking points into playable credit can also be implemented using the system of  FIG. 1  as described in U.S. patent application Ser. No. 09/134,598, now U.S. Pat. No. 6,371,852 which is also assigned to the assignee of the present application and which is also incorporated herein by reference for all purposes.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     Turning first to  FIGS. 1-4 , indicated generally at  10  is the upper portion of a slot machine. The slot machine is a commercially available electronic gaming device that has been modified as described herein. 
     One aspect of the modifications to slot machine  10  includes addition of a bracket  14  mounted on the front of the slot machine. The bracket includes two openings, the first containing a 640×240 touch-panel liquid crystal display (“LCD”)  16 . In the present embodiment of the invention, LCD  16  comprises a Hitachi SX16H005-AZA LCD. The second opening  18 , in  FIG. 1 , contains a card reader having a slot  20  (visible in  FIG. 7 ), into which a player&#39;s card is received as is known in the art. As shown in  FIG. 7 , both LCD  16  and slot  20  are framed by respective bezels  22 ,  24 . Card reader bezel  24  and slot  20  are not shown in  FIG. 1 . 
     Turning now to  FIG. 5 , the schematic components depicted therein on the left side of dashed line  26  are all contained within the cabinet that houses slot machine  10  in  FIG. 1 . Slot machine electronics  28  is part of the original slot machine structure provided by the slot-machine manufacturer. The additional components on the left side of line  26 , however, are all added to implement the invention in association with electronics  26  and the network. 
     The components within the slot machine, i.e., on the left side of line  26 , are connected to a computer network, along with numerous additional slot machines having the related structure depicted in  FIG. 5 . The network is illustrated as a computer  30  on the right side of dashed line  28 . Networked slot machines are known in the art and are depicted in &#39;961 and &#39;125 patents. The network includes databases for storing slot machine transactions and player tracking data, servers for implementing system games and bonuses, configuration work stations for configuring the system games and bonuses, and a Content Manager, which is a program implemented on a network computer that permits an operator of the system, typically a casino, to customize and configure images that appear on display  16 . 
     The slot-machine electronics  28  are connected to a system-machine interface board  31  via a wiring harness  32 . Board  31  provides communications between the slot machine electronics  28  and network  30  in a manner that is described in the &#39;961 and &#39;125 patents. A power supply  34  provides power to board  31 . A wiring harness  35  connects board  31  with the display and associated electronics  36 . Another harness connects board  31  to the network including computer  30 . The power supply also supplies power to electronics  36  and to a card reader  38 . The card reader is behind bezel  24  in  FIG. 7  and includes slot  20 . 
     Turning now to  FIG. 6 , additional details of the display and associated electronics  36  in  FIG. 5  are depicted schematically. 
     A dedicated computer  39  includes an LCD controller and electronics for enabling VGA touch panel images and sound for LCD  16 . In the present embodiment of the invention, computer  39  is a commercially available processor board manufactured by Intrinsyc. It includes an Intel ARM processor and a Windows CE operating system. Computer  39  also includes nonvolatile memory for storing images and sounds that are utilized as described hereinafter. An amplifier  40  provides sound signals to speakers  42 ,  44 , which are partially visible in  FIG. 7 . 
     In the present embodiment of the invention, the networked slot machines are initially configured using the Content Manager, which—in the present embodiment of the invention—runs on the same network PC platform as a configuration work station, which enables files to be downloaded to the system-machine interface board, like board  31 , associated with each slot machine. Once the screens and features of individual screens are selected at the Content Manager, an initialization file is created that identifies which MMC files and features have been selected. The configuration workstation can then be used to download the initialization file and associated MMC files to all the machines, to groups of machines, or even to a single selected machine. These initialization files and associated MMC files are stored in nonvolatile memory in electronics  36 . All parameters associated with the audio content and with display  16  can be configured in this manner. 
     In operation of the prior art VFD, System Tokens—such as a player&#39;s name or accrued points—are embedded in a slot-machine message comprising otherwise constant text strings that appear on the VFD. For example in the message Hello Richard, Hello comprises a constant text string and Richard comprises the System Token, here, the player name associated with the player card in use. 
     In the present invention, an MMC Token is embedded in the prior art VFD message, which may include System Tokens, that is transmitted to board  31  by the network and from there to board  39 . As a result, if the message is received by a slot machine with a VFD, the usual VFD message is displayed. If it is received by a slot machine with an LCD, the MMC message identified by the MMC Token is called from storage in electronics and run, incorporating any System Tokens as specified in the network message. But when a VFD message that does not include an MMC Token is received at an LCD machine, the  FIG. 8  emulation screen appears bearing the VFD message in the upper half, and emulating a prior art keypad, which is associated with the VFD in prior art machines. This feature permits gradual introduction of LCD machines on a network and gradual introduction of MMC messages to any LCD machines that are on the network. Multimedia content can thus be downloaded on the gaming-machine network and displayed on the LCD as described above. 
     In  FIG. 8 , display  16  is shown with an image that appears when the system emulates a prior art vacuum florescent display (VFD), like that disclosed in the &#39;961 and &#39;125 patents. The touch screen display image includes a keypad  40 , a message screen  41 , a bonus button  42 , a casino logo  44 , and a time display  46 . Unless it is otherwise clear from the context, use of the term “button” herein refers to an image of a button on the touch screen, which enables a player to interact with the network by touching screen  16  over the button image. The casino operator has the option, implemented via the Content Manager, of displaying various features such as the bonus button and the system time, dependent upon the operator&#39;s preference. Emulation mode is advantageous in two situations. First, if the touch screen display has not been configured, or configured incorrectly, the image of  FIG. 8  appears. Second, when prior art systems are retrofitted to include some slot machines that incorporate the touch screen LCD of the present invention and others that incorporate the prior art VFD, there may be some network display messages that are not implemented with the multimedia content (“MMC”) used by LCD  16 . If so, the system defaults to VFD emulation mode, in which VFD messages are displayed on message screen  41 , while the player enters commands using keypad  40  and bonus button  42 . In this mode, touch keypad  40  and the message panel  41  emulate the behavior of the prior art VFD and keypad, respectively. 
     In another embodiment of the invention, a separate network, i.e., a different network from one computer  30  is on, is connected to board  39 . This separate network provides MMC to board  39  for displaying images or playing audio. Such a network could be used to deliver real-time multimedia content to the display  16  and speakers  42 ,  44 . In addition, this network is used to deliver real-time video, either broadcast or closed circuit, to the display while play is ongoing. The keypad image on the touch screen display is used by the player to select a broadcast or closed-circuit channel. This configuration could permit a player to watch, e.g., a sporting event or other show while gaming. 
       FIG. 9  depicts an example of display  16  in idle-attract mode, i.e., when there is no player card inserted in slot  20 . When there is no card, the system displays up to 32 full size screens in a repeating sequence. Using a computer and keyboard on the network, the operator can control the duration, time of day, and sound associated with the idle-attract mode. 
     Turning to  FIG. 10 , the display is shown as it appears after a player enters his or her card into slot  20  of the card reader. This display includes a title, Pin Entry, PIN being an acronym for Personal Identification Number, a number that is stored on the network in association with the player&#39;s account. Also included is a casino logo  48 , in the present embodiment of the invention, the logo of the assignee being utilized for illustrative purposes. In the upper right-hand corner of the display are an Exit button  50  and a Help button  52 . Exit button  50  permits the player to cancel current operations or to move back to the previous screen. In  FIG. 10 , if Exit button  50  is pressed, the system resumes the idle-attract mode of  FIG. 9 . Pressing Help button  52  retrieves up to 8 screens of help information (e.g., as shown in  FIG. 14 ) that can be configured on the Content Manager. 
     The display of  FIG. 10  also includes a touch keypad  54 , a touch Enter button  56 , a touch Cancel button  58 , and a PIN entry field  60 , which displays an asterisk each time a digit from the player&#39;s PIN is entered on keypad  54 . 
     In operation, when a player enters his or her card into slot  20 , the  FIG. 10  image appears on display  16 . The player enters the PIN associated with the player card by pressing the digits on keypad  54  and hitting Enter button  56 . The Content Manager can be used to change the number of PIN digits required. There is also an auto enter feature that can be implemented at the Content Manager that sends the PIN to board  31  without waiting for the player to push the Enter button. 
     If, however, a player&#39;s card format cannot be recognized when it is inserted into slot  20 , the display of  FIG. 11  appears. 
     When the format is recognized and the PIN is transmitted to board  31 , the card information and PIN stored on a network computer is compared with those entered at slot machine  10 . If there is a match, the image of  FIG. 12  is displayed. The  FIG. 12  image includes a personalized welcome, using the name associated with the player account, and a replica of the player card  62 . Speakers  42 ,  44 , also play accompanying audio. The system operator can control the colors on the image of  FIG. 12  via the Content Manager. The screen will persist on the display for up to 30 seconds, a time that can also be configured by the operator on the Content Manager. 
     In addition, the system is configured to require the PIN as described above each time the player is either requesting personal information, such as cash or point balances, or issuing commands to effect account changes, such as transferring cash to or from a slot machine. This provides increased account security, including protecting the player&#39;s account in the event that he or she leaves the game without withdrawing the card. 
     After the welcome screen of  FIG. 12 , a session screen, shown in  FIG. 13  is displayed. A Menu button  53  calls the image of  FIG. 17  as later discussed in more detail. The session image includes the player&#39;s name at the top and displays and updates the player&#39;s total player tracking points (Total Points), points accrued during the current session (Session Points), and additional coins to play necessary to generate additional points (Coins to Go). The Coins to Go display can be enabled or not depending upon the operator&#39;s preference, using the Content Manager. The image of  FIG. 13  persists until the player takes some action or the system interrupts the session screen with a higher priority display.  FIG. 14  depicts another image of the  FIG. 13  session screen after Help button  52  is touched. This displays a stored help screen relating to—in this case—the session screen. The help displayed is in the context of the current screen upon which Help button  52  is touched, i.e., the help relates to the display on the current screen. 
       FIG. 15  is another version of the  FIG. 13  session screen. The  FIG. 15  image does not include the Coins to Go field as a result of a configuration command entered by the casino operator on the Content Manager. 
       FIG. 16  is still another implementation of the session screen of  FIGS. 13 and 15 , which includes a session-attract area  64 . When the session-attract feature is implemented, area  64  is configurable to display up to 32 screens in any sequence. When the sequence ends, it repeats in round-robin fashion. Each displayable screen has a programmable duration, time of day control, and sound controls, all of which are programmable by the operator using the Content Manager. The session-attract area may also be used to notify players of special events and awards. 
       FIG. 17  depicts a menu-mode screen, which is initiated when the player touches Menu button  53 . Menu screens contain two touch screen buttons in the upper right-hand corner, namely Exit button  50  and Help button  52 . As previously mentioned, the Exit button allows the player to cancel current operations or move back to the previous screen. Any of the four buttons on the left are pushed to select different menu options. 
     For example, touching the Account Balance button in  FIG. 17  produces the menu display screen of  FIG. 18 . Pushing each of the buttons on the left of  FIG. 18  provides the corresponding balance on the right of the screen. The Points Balance button provides the balance of player tracking points. Touching the Point Play Balance button shows the value of machine credits that have been converted by the player at the gaming machine from player tracking points. These credits are referred to by applicant as Xtra Credit points and are described in applicant&#39;s co-pending &#39;065 application. 
     The Coinless Balance button in  FIG. 18  provides a balance for a player&#39;s cashless play account as described in applicant&#39;s co-pending &#39;598 application. 
     Returning again to  FIG. 17 , when Point Play button is touched, the image of  FIG. 19  appears on the screen. This is the feature that allows players to convert their point balances into game playable credits (Xtra Credit). On the image of  FIG. 19 , the player selects one of the dollar amounts of credits that he or she wishes to exchange for points in the player&#39;s account. Touching, e.g., the $5 button in  FIG. 19  produces the Point Play image of  FIG. 20 . Touching the Confirm button in  FIG. 20  moves $5.00 of Xtra Credit to the player&#39;s Xtra Credit account, designated “Point Play Balance” in  FIG. 18 . 
     Turning now to  FIG. 21 , an Xtra Credit display replaces the Welcome display of  FIG. 12  when a player has Xtra Credit. The player then plays off any Xtra Credit, and—after doing so—the session screen, like, e.g., the session screen of  FIG. 13 , is displayed. 
       FIG. 22  illustrates a Hand Pay display, which appears whenever the slot machine is in a hand pay condition. This typically occurs for large jackpots or bonus awards that are too large to apply to the machine&#39;s credit meter. This display persists until the hand pay condition is cleared from the slot machine, typically by an attendant who arrives to clear the machine in a known manner. 
       FIG. 23  depicts a Return Play screen which is associated with the return play bonus, described in the &#39;961 patent. Briefly, upon earning a pre-determined number of points in a session, the player is awarded gaming credits that cannot be played until after a pre-determined later time. This induces the player to return to the casino to play off his or her credits. 
       FIG. 24  depicts a screen that appears when the player is a winner of the Lucky Coin bonus, a random award that is described in applicant&#39;s U.S. Pat. No. 6,375,569, issued Apr. 23, 2002. 
       FIG. 25  informs the player that the multiple jackpot bonus is in effect, a bonus promotion described in the &#39;961 patent. 
     Upon withdrawal of the player&#39;s card, the image of  FIG. 26  is displayed. The image persists on the screen for a period of up to 10 seconds, which can be designated by the operator on the Content Manager. 
     In another aspect of the present invention, the display can be used to implement what are sometimes referred to as secondary or top-box games. For example, U.S. Patent Application Ser. No. 60/282,703 discloses a secondary game that includes a display mounted on the top of a commercially available slot machine. The same secondary game can be implemented via software stored on board  38 . This software can drive display  16  in the same fashion as the upper portion of the game described in the &#39;703 application. A percentage of each coin played in a session can be allocated to a pool personal to the player. This pool can fund an award resulting in playing the secondary game implemented on display  16 . The sound associated with that secondary game is played via speakers  42 ,  44 . 
     In addition, a subset of slot machines on the casino network can be grouped to provide a secondary game in which multiple players participated as shown in U.S. patent application Ser. No. 09/104,145, now U.S. Pat. No. 6,375,567 which is assigned to the assignee of the present application and which is incorporated herein by reference for all purposes. Software implementing that game can be used to cause the display  16  on each of the grouped machines to depict substantially the same graphics associated with the secondary game screen as shown in the &#39;145 application. 
     Finally, a subset of the slot machines or the entire network could be selected for periodic bonus games that utilize display  16 .
