- The present inventive concepts relate to an input device for an electronic gaming machine, and in particular to an input device that is actuated by the feet of a user.
- Electronic and electro-mechanical gaming machines (EGMs) are systems that allow users to place a wager on the outcome of a random event, such as the spinning of mechanical or virtual reels or wheels, the playing of virtual cards, the rolling of mechanical or virtual dice, the random placement of tiles on a screen, etc. Manufacturers of EGMs have incorporated a number of enhancements to the EGMs to allow players to interact with the EGMs in new and more engaging ways. For example, early slot machines allowed player interaction by pulling a lever or arm on the machine. As mechanical slot machines were replaced by electronic slot machines, a range of new player interface devices became available to EGM designers and were subsequently incorporated into EGMs. Examples of such interface devices include electronic buttons, wheels, and, more recently, touchscreens and three dimensional display screens.
- Previous electronic gaming machines for wagering relied on hand operated controls. More recently, EGMs have been developed that allow players to interact with the machine using other types of inputs, such as haptic sensors, eye tracking, etc. Some video game systems and machines allow input using a user's feet, such as the foot touchpad used in Dance Dance Revolution by Konami or the Wii balance board by Nintendo. Such input devices may not be ideal for using in a casino environment, however, because they may require the user to stand on the input device, while casino patrons often prefer to sit while playing EGMs in a casino environment.

FIG. 1A is a top view andFIG. 1B is a side view of aninput device 10 according to some embodiments. As shown therein, in some embodiments, theinput device 10 includes a generally bowl-shapedlower body 15 including a generally convexlower surface 15B and a generally flatupper surface 15A. In operation, theinput device 10 may be oriented such that the convexlower surface 15B faces downwards and rests on the floor or on a base, mat or other surface, and the flatupper surface 15A faces upwards. A player may operate theinput device 10 by resting or placing his or her feet on theupper surface 15A and tilting theinput device 10 forwards, backwards, or side to side, or by rotating theinput device 10 about a central axis normal to the flatupper surface 15A (i.e., in the z-direction) with their feet. Accordingly, theinput device 10 may have at least three degrees of freedom, namely, rotation about the x-, y- or z-axis illustrated inFIGS. 1A and 1B . Because of the bowl-shaped configuration of thelower body 15 of theinput device 10, the input device can be rotated about all three axes simultaneously. - The
input device 10 may include afoot pad 12 on theupper surface 15A of thelower body 15 that is arranged to receive the feet of the player as indicated by thefootprints 13 on thefoot pad 12. A pressure sensor orload cell 16 may be provided between theupper surface 15A of thelower body 15 and thefoot pad 12 that detects when pressure is applied to thefoot pad 12 and responsively generates an electrical signal that is proportional to the amount of force applied to thefoot pad 12. - The
input device 10 may further include avibration unit 14 that vibrates in response to a signal from the EGM to provide haptic feedback to the player through vibration of the player's feet. Such feedback may be incorporated into game play on the EGM, for example, to provide feedback to the player upon the occurrence of a predetermined event during game play. - The
input device 10 may further include acounterweight 19 provided as an eccentric mass in a lower portion of thelower body 15 that urges the input device to return to an upright position when pressure is not being applied to thefoot pad 12. - The
input device 10 may further include a 3-axis motion sensor 18 that senses rotation of thelower body 15 about the x-, y- and z-axes and generates an electrical signal indicative of angular motion of theinput device 10. Themotion sensor 18 may, for example, include a three-axis accelerometer, such as an ADXL345 3-axis digital MEMS accelerometer manufactured by Analog Devices, Inc. - The electrical signal indicative of the motion of the
input device 10 is provided to an EGM, which controls the operation of a game in response to the electrical signal, as will be described in more detail below. - The
input device 10 illustrated inFIG. 1B has a generally hemispherical shapedlower body 15. However, thelower body 15 may have a different shape, such as only a partial section of a sphere. For example, as shown inFIG. 1C , theinput device 10 may include a shallow bowl-shapedlower body 15′ that does not form a complete hemisphere. Other configurations of thelower body 15 are possible. For example, thelower body 15 may include ridges, protrusions, or other non-spherical portions that provide tactile feedback causing theinput device 10 to favor motion in one direction over another. Stops or limiters could also be formed or provided on thelower body 15 to prevent it from tilting too far in a given direction. -
FIG. 2A is a top view andFIG. 2B is a side cross sectional view of aninput device 10B according to further embodiments. Theinput device 10B has a pair of foot pads includingleft foot pad 22A andright foot pad 22B on which a player may put his or her feet. Acorresponding load cell respective foot pads foot pads right vibration units respective foot pads - In some embodiments, the input device may be positioned on or within a housing that provides support for the input device.

FIG. 3A , theinput device 10C may include features that prevent thelower body 15 from pitching or rolling too far in a given direction. For example, theinput device 10C may include anarm 28 that protrudes from the lower body into anotch 52 in thebase 50. When thelower body 15 pitches or rolling by a predetermined amount in a given direction, thearm 28 may contact an inner surface of thenotch 52, preventing further movement in that direction. In some embodiments, the cavity may be filled with a viscous liquid that opposes movement of thearm 28 to control a rate at which the lower body rolls and pitches. In addition, fins or other features may be provided on thearm 28 to control a rate at which the lower body yaws. - To determine the position of the
lower body 15, theinput device 10C may include anillumination source 62, such as a visible or infrared LED, and anoptical sensor 64. The illumination source illuminates a region of the outer surface of thelower body 15, and theoptical sensor 64 sequentially generates images of the illuminated region. Two dimensional motion of the lower body can be detected by digitally correlating sequential images generated by theoptical sensor 64. Motion detection using digital image correlation is used, for example, to detect motion of an optical mouse. To assist with detection of movement, an optical pattern may be formed on the outer surface of thelower body 15. - The base 50 may further include one or
more speakers 66 to provide audio feedback to the player. - Referring to
FIG. 3B ,input device 10D according to some embodiments includes acollar 35 that extends circumferentially around an upper portion of thelower body 15 to prevent thelower body 15 from rolling or pitching too far in any direction. That is, when thelower body 15 rolls or pitches by a predetermined angle determined by the dimensions of thebase 50, thelower body 15 and thecollar 35, thecollar 35 will strike thebase 50, preventing further movement in that direction. - Referring to
FIG. 3C , aninput device 10E according to some embodiments may include anarm 48 that protrudes from the base 50 into anotch 42 in thelower body 15. When thelower body 15 pitches or rolling by a predetermined amount in a given direction, thearm 48 may contact an inner surface of thenotch 42, preventing further movement in that direction. -
FIG. 4 is a side cross sectional view of an input device 10F including a base 50 according to further embodiments. In the input device 10F, thelower body 15 is suspended from the base 50 by magnetic levitation. In particular, a plurality ofpermanent magnets 72A. 72B, 72C are provided in the lower body, while a plurality ofelectromagnets electromagnets permanent magnets 72A. 72B, 72C to be repelled from theelectromagnets lower body 15 from thebase 50. Conversely, energizing theelectromagnets permanent magnets 72A. 72B, 72C to attract theelectromagnets lower body 15 being locked in place on thebase 50. As with the embodiment ofFIG. 3B , acollar 35 can be provided on thelower body 15 to limit rotation of thelower body 15. -
FIG. 5 is a perspective view of aninput device 10 and an electronic gaming machine (EGM) 100. In particular,FIG. 5 illustrates that theinput device 10 may sit between anEGM 100 and achair 120. A player may sit in thechair 120 and use theinput device 10 to control various operations of theEGM 100. In some embodiments, theinput device 10 may be integrated into either theEGM 100 or thechair 120. -
FIG. 6 is a functional block diagram showing various electronic aspects of aninput device 10 according to some embodiments. - The
input device 10 includes amicrocontroller 40 which may include integrated memory or cache. The microcontroller 20 controls the operations of theinput device 10 according to a program stored in the memory. The memory may include flash memory, EEPROM or other non-volatile memory that retains its programming even when power to the device is disconnected. - The
input device 10 may include various sensors, including left andright load sensors right foot pads FIG. 2 ), a 3-axis accelerometer 18 that detects rotation about an x, y and z axis, and aposition sensor 46 that detects movement of thelower body 15. Theposition sensor 46 may be provided instead of or in addition to the 3-axis accelerometer 18. - Signals output by the left and
right load sensors axis accelerometer 18 are amplified byamplifiers 32 and output to an A/D converter 36 by amultiplexer 34 under the control of themicrocontroller 40. - The
input device 10 further includes output devices for outputting tactile or audio feedback to the player. The output devices include ahaptic feedback unit 14 and aspeaker 25, each of which is coupled to and controlled by themicrocontroller 40. Thehaptic feedback unit 14 generates vibrations that are transmitted to the feet of the user as feedback. Thehaptic feedback unit 14 may generate vibrations, for example, by rotating an eccentric mass about a drive shaft. - In some embodiments, the
input device 10 may include anelectromagnet controller 44 for controlling the electromagnetic levitation of thelower body 15, as illustrated in the embodiment ofFIG. 4 . - The
input device 10 may further include aserial data adapter 42 for outputting serial data to an EGM through anoutput connector 48. Theserial data adapter 42 may include a USB adapter, a UART adapter, or any other suitable interface for communicating serial data to an EGM. - In some embodiments, the
input device 10 may include a wireless communication adapter 54 which enables theinput device 10 to communicate with an EGM using a wireless communication protocol, such as Bluetooth, NFC, Wi-Fi or other protocol. - Position, force and/or motion data generated by the
input device 10 is transmitted to the EGM through theoutput connector 48 or the wireless communication adapter 54. Such data may be used by the EGM to control operation of a game on the EGM. - For example, an
input device 10 according to some embodiments may be used in conjunction with an EGM having a 3D display. In that case, a player may use theinput device 10 to control an avatar in the game without touching the screen. Referring toFIG. 7 , aprimary display screen 116 of an EGM is illustrated along with aninput device 10 according to some embodiments. An avatar orcharacter 82 would appear on the 3D display, and would move through a 3D world based upon the tilting and turning of the user's feet. The speed at which the avatar moves may be proportional to the angle at which the input device is tilted and/or the force applied to the input device by the player's feet. The player could traverse the avatar through a series of mazes, using their feet to control the movement of theavatar 82. Using the pressure control of the controller, the user could make the avatar jump by raising their feet off the controller. - As another example, a player could control a virtual camera that shows the view seen by an avatar by rotating the
input device 10 in a clockwise or counter-clockwise direction (i.e., yaw rotation about the z-axis) so that the avatar would appear to be looking in different directions around a virtual world. - As a further example, referring to
FIG. 8 , a player could use aninput device 10 to cause anavatar 82 to traverse a selection screen displaying multiplevirtual gaming machines 100A-100C. For example, the player could use theinput device 10 to cause theavatar 82 to walk to different virtual game machines displayed on the EGM and to face the virtual game machine the player wishes to play. Once theavatar 82 is facing themachine 100A-100C the player wishes to play, the player could push down on theinput device 10 to allow select the game. Another option would be to have portals that have versions of game to select, where the player causes theavatar 82 to walk through a portal using the input device and enter a virtual world containing the game. - Referring to
FIG. 9 , in a 3D maze game, a player could control a ball 84, and have the input device tilt the world and move the ball through the level (i.e., tilt the surface of the level). The level could contain multiplecollectable items 86 with a goal of gathering a specified amount to finish the level. When the player collects objects, the haptic system in the controller could vibrate. Another instance could have a hold in the level, in which the player must tilt the world with theinput device 10 and get the ball through the maze and to the opening to exit the level. - An
input device 10 may also be used to control a traditional reel-style gaming game, for example, by using the player control of the input device as a button. Tilting the controller forward and back could trigger the reels to start spinning. Theinput device 10 could be used to nudge the reels once they are stopped, by rocking the controller. The reels could be nudged up or down depending on which way theinput device 10 is tilted. Another use of theinput device 10 would be to start a reel spin by tilting the controller back and forth. The player could change bets by tilting theinput device 10 back to select/adjust a wager and moving theinput device 10 sideways to select a wager. - In some embodiments, the
input device 10 may be used as part of a bonus game. For example, referring toFIG. 10 , a bonus game on an EGM may include simulated panning for gold. Avirtual pan 90 is displayed on the screen and filled with virtual dirt that may contain virtual gold. The pan's movements would be tied to the tilt tracking of theinput device 10 and would reveal to the player whether or notgold nuggets 94 are contained in the virtual dirt asvirtual water 92 is poured into the pan. The player could push down on theinput device 10 to increase the amount of water poured into thepan 90. Once the dirt has been cleared out of the pan, the prize amount would be revealed. If the player tilts the controller too much, the pan can empty and the player loses the bonus feature. - As a still further example, referring to
FIG. 11 , theinput device 10 could also be used to control a 3rd person perspective airplane bonus feature where anairplane 96 is seen moving forward. The movement of theinput device 10 would control the pitch and roll of theairplane 96, as well as being able to perform a barrel roll if the controller is rotated. When theairplane 96 is hit by enemy fire, the haptic feature of the input device would then give the player feedback. Pushing down on the input device would allow theairplane 96 to fire a stronger attack. - Electronic Gaming Machines
