  • FIELD
  • [0003]
    The embodiments relate generally to portable wagering game machines and more particularly to detecting location or proximity of portable wagering game machines in gaming environments.
  • BACKGROUND
  • [0004]
    Wagering game machines have traditionally been operated as a stand alone unit, or linked in a network of some type to a group of gaming machines. In general, these traditional wagering game machines are relatively large and have not been portable. That is, once placed on a casino floor the wagering game machine does not move unless it is replaced with another wagering game machine or if the gaming establishment redesigns the layout of the casino floor.
  • [0005]
    However, as technology in the gaming industry progresses, some jurisdictions are moving towards allowing portable gaming machines. Portable wagering game machines are typically small, handheld devices that may be taken from place to place. While such portability provides increased flexibility to gaming establishments and may enhance a user's wagering game experience, several issues are presented regarding portable wagering game machines. A first issue is that jurisdictions typically restrict wagering games to limited locations within a gaming establishment. Such restrictions are more difficult to enforce with portable wagering game machines.

  • [0016]
    FIG. 1 shows an example embodiment of a portable wagering game machine (PWGM) 100. The portable wagering game machine 100 can include any suitable electronic handheld or mobile device configured to play a video casino game such as blackjack, slots, keno, poker, blackjack, and roulette. The wagering game machine 100 comprises a housing 112 and includes input devices, including a value input device 118 and a player input device 124. For output, the wagering game machine 100 includes a primary display 114, and may include a secondary display 116, one or more speakers 117, one or more player-accessible ports 119 (e.g., an audio output jack for headphones, a video headset jack, etc.), and other conventional I/O devices and ports, which may or may not be player-accessible. In the embodiment depicted in FIG. 1, the wagering game machine 100 includes a secondary display 116 that is rotatable relative to the primary display 114. The optional secondary display 116 can be fixed, movable, and/or detachable/attachable relative to the primary display 114. Either the primary display 114 and/or secondary display 116 can be configured to display any aspect of a non-wagering game, wagering game, secondary game, bonus game, progressive wagering game, group game, shared-experience game or event, game event, game outcome, scrolling information, text messaging, emails, alerts or announcements, broadcast information, subscription information, and wagering game machine status.
  • [0017]
    The player-accessible value input device 118 can comprise, for example, a slot located on the front, side, or top of the casing 112 configured to receive credit from a stored-value card (e.g., casino card, smart card, debit card, credit card, etc.) inserted by a player. The player-accessible value input device 118 can also comprise a sensor (e.g., an RF sensor) configured to sense a signal (e.g., an RF signal) output by a transmitter (e.g., an RF transmitter) carried by a player. The player-accessible value input device 118 can also or alternatively include a ticket reader, or barcode scanner, for reading information stored on a credit-ticket, a card, or other tangible portable credit or funds storage device. The credit ticket or card can also authorize access to a central account, which can transfer monetary value to the wagering game machine 100.
  • [0018]
    Still other player-accessible value input devices 118 can require the use of touch keys 130 on the touch-screen display (e.g., primary display 114 and/or secondary display 116) or player input devices 124. Upon entry of player identification information and, preferably, secondary authorization information (e.g., a password, PIN number, stored value card number, predefined key sequences, etc.), the player can be permitted to access a player's account. As one potential optional security feature, the wagering game machine 100 can be configured to permit a player to only access an account the player has specifically set up for the wagering game machine 100. Other conventional security features can also be utilized to, for example, prevent unauthorized access to a player's account, to minimize an impact of any unauthorized access to a player's account, or to prevent unauthorized access to any personal information or funds temporarily stored on the wagering game machine 100.
  • [0019]
    The player-accessible value input device 118 can itself comprise or utilize a biometric player information reader which permits the player to access available funds on a player's account, either alone or in combination with another of the aforementioned player-accessible value input devices 118. In an embodiment wherein the player-accessible value input device 118 comprises a biometric player information reader, transactions such as an input of value to the wagering game machine 110, a transfer of value from one player account or source to an account associated with the wagering game machine 100, or the execution of another transaction, for example, could all be authorized by a biometric reading, which could comprise a plurality of biometric readings, from the biometric device.
  • [0020]
    Alternatively, to enhance security, a transaction can be optionally enabled only by a two-step process in which a secondary source confirms the identity indicated by a primary source. For example, a player-accessible value input device 118 comprising a biometric player information reader can require a confirmatory entry from another biometric player information reader 152, or from another source, such as a credit card, debit card, player ID card, fob key, PIN number, password, hotel room key, etc. Thus, a transaction can be enabled by, for example, a combination of the personal identification input (e.g., biometric input) with a secret PIN number, or a combination of a biometric input with an authentication fob input, or a combination of a fob input with a PIN number, or a combination of a credit card input with a biometric input. Essentially, any two independent sources of identity, one of which is secure or personal to the player (e.g., biometric readings, PIN number, password, etc.) could be utilized to provide enhanced security prior to the electronic transfer of any funds. In another aspect, the value input device 118 can be provided remotely from the wagering game machine 110.
  • [0021]
    The player input device 124 may include a plurality of push buttons on a button panel for operating the wagering game machine 100. In addition, or alternatively, the player input device 124 can comprise a touch screen mounted to the primary display 114 and/or secondary display 116. In one aspect, the touch screen is matched to a display screen having one or more selectable touch keys 130 selectable by a user's touching of the associated area of the screen using a finger or a tool, such as a stylus pointer. A player enables a desired function either by touching the touch screen at an appropriate touch key 130 or by pressing an appropriate push button on the button panel. The touch keys 130 can be used to implement the same functions as push buttons. Alternatively, the push buttons 126 can provide inputs for one aspect of the operating the game, while the touch keys 130 can allow for input needed for another aspect of the game. The various components of the wagering game machine 100 can be connected directly to, or contained within, the casing 112, as seen in FIG. 1, or can be located outside the casing 112 and connected to the casing 112 via a variety of wired (tethered) or wireless connection methods. Thus, the wagering game machine 100 can comprise a single unit or a plurality of interconnected (e.g., wireless connections) parts which can be arranged to suit a player's preferences.
  • [0022]
    The operation of the basic wagering game on the wagering game machine 100 is displayed to the player on the primary display 114. The primary display 114 can also display a bonus game associated with the basic wagering game. The primary display 114 preferably takes the form of a high resolution LCD, a plasma display, an LED, or any other type of display suitable for use in the wagering game machine 100. The size of the primary display 114 can vary from, for example, about a 2-3″ display to a 15″ or 17″ display. In at least some embodiments, the primary display 114 is a 7″-10″ display. In one embodiment, the size of the primary display can be increased. Optionally, coatings or removable films or sheets can be applied to the display to provide desired characteristics (e.g., anti-scratch, anti-glare, bacterially-resistant and anti-microbial films, etc.). In at least some embodiments, the primary display 114 and/or secondary display 116 can have a 16:9 aspect ratio or other aspect ratio (e.g., 4:3). The primary display 114 and/or secondary display 116 can also each have different resolutions, different color schemes, and different aspect ratios.
  • [0023]
    A player typically begins play of the basic wagering game on the wagering game machine 100 by making a wager (e.g., via the value input device 118 or an assignment of credits stored on the portable wagering game machine 100 via the touch screen keys 130, player input device 124, or buttons 126) on the wagering game machine 100. In some embodiments, the basic game can comprise a plurality of symbols arranged in an array, and includes at least one payline 132 that indicates one or more outcomes of the basic game. Such outcomes can be randomly selected in response to the wagering input by the player. At least one of the plurality of randomly selected outcomes can be a start-bonus outcome, which can include any variations of symbols or symbol combinations triggering a bonus game.
  • [0024]
    In some embodiments, the player-accessible value input device 118 of the wagering game machine 100 can double as a player information reader 152 that allows for identification of a player by reading a card with information indicating the player's identity (e.g., reading a player's credit card, player ID card, smart card, etc.).

  • [0047]
    FIG. 4 is a block diagram of an example system 400 of wireless signal sources 310, portable wagering game machines 100 and servers 330 in a gaming establishment and is used to illustrate embodiments of the invention. In some embodiments, an array of wireless access points (which may be low power wireless access points) are placed in predetermined locations. The access points 310 may be positioned in a pattern or grid to facilitate location within a coordinate system. Alternatively, the access points may be positioned at specific locations such as tables or seating areas with no particular pattern. The location of each wireless access point may be maintained in a database 336.
  • [0048]
    The system may also include one or more server 330, which may be central game controllers. PWGMs 100 may communicate through the wireless access points 310. As illustrated in FIG. 3, server 330 may be programmed or supplied with the actual locations of the wireless access points, such as through database 336.
  • [0049]
    In some embodiments, access points 310 are part of a mesh network to reduce wiring and installation cost. However, the access points may be hardwired to the server 330 to provide increased bandwidth. Hybrid schemes are also possible where some of the access points 310 are hardwired and others reside on a mesh network.
  • [0050]
    Each PWGM 100 may be assigned a unique identifier that is used in communication via the wireless access points. Based on location and signal strength, more than one access point 310 may establish communication with a particular PWGM 100. In some embodiments, the system will include the received signal strength in the information reported to a location management server 332 on server 330. This information may then be used by the location management service 332 to interpolate the actual location of the PWGM 100.
  • [0051]
    FIG. 5 is a block diagram of an example system 500 of wireless signal sources according to further embodiments of the invention. In some embodiments, system 500 implements an array of wireless signal sources comprising point locator transmitters 502. These points are arranged in a pattern such as the grid 504 illustrated in FIG. 5. It should be noted that although a grid is depicted, any predetermined arrangement of points may be used.
  • [0052]
    Each point transmitter 502 transmits a unique locator signal that corresponds to a specific point within the pattern. These locator signals are designated as X0Y0-X3Y3 in FIG. 5. By receiving locator signals from at least one point the approximate location of a PWGM 100 may be determined.
  • [0053]
    In some embodiments, system 500 may also include one (or more) server 330 s, which may be central game controllers, and one (or more) Wireless Access Points 310. The servers 330 and the PWGMs 100 communicate through the Wireless Access Points 310.
  • [0054]
    In some embodiments, a PWGM 100 reports the received locator location signal(s) to a location management service 332 on server 330. From this information the location management service may determine the location of each PWGM 100.
  • [0055]
    In some embodiments, to prevent a rogue PWGM 100 from spoofing the system or reporting a false location, it is desirable that the unique locator signals be encoded and changed frequently in a random or unpredictable manner such that the correspondence between a particular locator signal and a locator point is only known to the server 330. This will prevent a rogue PWGM from sending a predetermined “good” location regardless of its actual location.
  • [0056]
    Based on location and locator signal strength, a PWGM 100 may receive signals from more than one locator point 502. The system may include the received locator signal strength in the information reported to the location management service 332. This information may then be used to interpolate the actual location of the PWGM 100.
  • [0057]
    FIG. 6 is a block diagram of an example system 600 of wireless signal sources according to still further embodiments of the invention. In general, system 600 includes a grid 604 of location transmitters 602. System 600 employs a number of transmission wires 606. These wires 606, which act as antennas are arranged in an intersecting pattern such as the grid 604 depicted in FIG. 6. It should be noted that although a grid is depicted, any predetermined arrangement of intersecting antenna wires may be used. The wires may be located in the floor or ceiling of the space being monitored.
  • [0058]
    Each wire 606 carries a unique locator signal that corresponds to a specific line within the pattern. These locator signals are designated as X0-X3 and Y0-Y3 in FIG. 6. By receiving locator signals from two intersecting wires the approximate location of a PWGM 100 may be determined.
  • [0059]
    The system may also include one (or more) servers 330, which may be central game controllers and one (or more) Wireless Access Points 310. The servers 330 and the PWGMs 100 communicate through the Wireless Access Points 310.
  • [0060]
    A PWGM 100 may report the received locator location signals to the server 330. From this information a server 330 may determine the location of the PWGM 100.
  • [0061]
    To prevent a rogue PWGM from spoofing the system or reporting a false location, it is desirable that the unique locator signals be encoded and changed frequently in a random or unpredictable manner such that the correspondence between a particular locator signal and a locator wire is only known to the server 339. This may aid in preventing a rogue PWGM from sending a predetermined “good” location regardless of its actual location.
  • [0062]
    Based on location and locator signal strength, a PWGM 100 may receive more than two intersecting locator signals. The system 600 may include the received locator signal strength in the information reported to the server 330. This information may then be used by the server 330 to interpolate the actual location of the PWGM 100.
  • [0063]
    In some embodiments, a single locator transmitter may be used. In this configuration the transmitter may be switched from one locator wire to the next in sequence.
  • [0064]
    In some embodiments, a PWGM 100 includes an inertial navigation system. The principles of inertial navigation systems are well known and are not fully detailed here. In general, an inertial navigation system provides the position, velocities and attitude of a platform by measuring the acceleration and rotation of the platform. It accumulates these measurements over time to calculate the current position and attitude.
  • [0065]
    Inertial navigation systems do not rely on any outside systems and are therefore immune to jamming and deception. However, errors in measurement and calculation are typically cumulative so the position and attitude of the platform may become progressively less accurate over time.
  • [0066]
    In some embodiments, an inertial navigation system into a location detector 242 of a PWGM 100. A PWGM 100 may calibrate its position whenever it is ‘docked’, for example at a docking station 312 and would rely on the inertial navigation system when it is not docked. In these embodiments, a PWGM 100 may report its location to the server 330.
  • [0067]
    In some embodiments, a hybrid of systems 400, 500 or 600 may used. For example, an array of low power access points may be used to determine the general location of the PWGM 100 and the inertial guidance system may be used to pinpoint its exact location.
