Description:
FIELD OF THE INVENTION 
       [0001]    The present invention relates to a hand held remote controller unit, and more particularly, to an integrated remote controller for operating a television and a video game player unit that is used in conjunction with the television. 
       DESCRIPTION OF THE RELATED ART 
       [0002]    Remote control units have long been used to facilitate users&#39; operation of televisions, video cassette recorders (VCR), home stereos, and other associated audio/video electronic equipment. Using wireless remote control units that transmit control commands to receiver units via infra-red (IR) signals, a user can perform a variety of operations, such as changing the volume or channel of a television, fast forwarding or scanning a videotape in a VCR, changing a preset radio station on a stereo receiver, or switching to a different track on a compact disc (CD) playing in a CD player, all from a distance away from the audio/video equipment. Although televisions and other assorted audio/video electronic equipment can be controlled without using a remote control, many users rely on the convenience of such hand-held portable controllers. 
         [0003]    As different types of audio/video equipment have become operable by remote control, a need has developed for converging the capabilities of remote control units to control the operation of different types of electronic equipment by a single unit. For example, remote control units are commercially available that control the operation of a television, VCR, and cable television set-top box with a single controller, as in Darbee et al., U.S. Pat. No. 4,959,810. Some remote control units are also programmable to “learn” the IR transmission format for different brands, so that a consumer can replace the individual remote controls intended for the consumer&#39;s different types of home audio/video equipment with a single remote control unit. These remote control units can reduce the clutter and confusion associated with operating a plurality of different remote control units. 
         [0004]    During the past few years, video game playing has become increasing popular for home entertainment as video game designers incorporate improvements to computerized graphics and special effects to create realistic video games and adventure simulations. The convergence of the Internet with television programming is also expected to bring added capabilities for video games and interactive television. For example, consumers may soon be able to participate as a contestant in television game shows, or may be able to play action or adventure games with others in different households. 
         [0005]    Video games are typically played using one or more hand-held control units that are directly connected to a video game console through a wire. The controllers typically include a “joystick” or series of “up/down/left/right” buttons, and a few other “action” buttons for shooting, firing, jumping, selecting, etc. While some video game systems are designed for all games to be playable with the same controller, others require users to obtain specially designed controllers for certain games (e.g., a driving game may require a controller that includes a steering wheel). In either case, this adds at least one more controller that is necessary for a user to operate the components in a home entertainment system. The user must therefore use one or more remote control units to adjust the features of a television (e.g., volume, picture contrast) and a connected stereo system, and then switch to a separate video game controller for video game playing. Switching between separate controllers may be inconvenient or unwieldy, particularly if the user is frequently switching between controller units. 
       SUMMARY OF THE INVENTION 
       [0006]    In view of the difficulties described above, there is a need for a method and apparatus for controlling the operation of both a television and a video gaming system with a single remote controller unit. In the preferred embodiment of the present invention, a hand-held remote control unit for controlling the operation of a television and other electronic audio/video components, such as a VCR, DVD player, or home stereo, operates in a different mode for use as a video game controller. The location and position of the push buttons on the remote controller unit are arranged such that a subset of the buttons that are for the television remote control are operable in a different mode as a video game controller. A user rotates the remote control unit from a first position to a second position to use the remote control unit for operating a video gaming system. For example, the first position could be a substantially vertical upright position, and the second position could be a substantially horizontal position. When used as a video game controller, the controller indicates which of the subset of buttons on the remote control are to be used for operating the video game. 
         [0007]    It is an object of the present invention to provide a remote control unit for controlling a plurality of electronic audio/video applications. The remote control includes a keypad arranged for receiving input to control either a first electronic audio/video application when the remote control unit is accessed in a first position or a second electronic audio/video application when the remote control unit is accessed in a second position. A CPU within the remote control generates control signals to control an electronic audio/video application based upon input received from the keypad. A memory is connected to the CPU for storing control signal data associated with input received by the CPU. At least one transmitter transmits control signals from the CPU to an electronic device for controlling either the first or second electronic audio/video application according to the position by which the remote control unit is accessed. 
         [0008]    It is another object of the present invention to provide a remote control unit having a plurality of pushbuttons arranged on a housing of the remote control unit for operating the remote control unit in a first hand-held position to control a first electronic device, a subset of the plurality of pushbuttons for operating the remote control unit in a second hand-held position to control a second electronic device, a CPU for receiving input from the pushbuttons and generating control signals for controlling either the first or second electronic device, and a first and second transmitter for transmitting control signals to control the respective first and second electronic devices. 
         [0009]    It is yet another object of the present invention to provide a remote control unit having a plurality of pushbuttons arranged on a housing of the remote control unit for operating the remote control unit to control a first electronic device, a subset of the plurality of pushbuttons for operating the remote control unit to control a second electronic device. A CPU receives input from the pushbuttons and generates control signals for controlling either the first or second electronic device. A transmitter transmits control signals to control the respective first and second applications. An illuminating display on the housing lights pushbuttons on the remote control unit, wherein only the subset of pushbuttons for controlling the second application of the electronic device are illuminated. 
         [0010]    It is also an object of the present invention to provide a method for controlling access to operation of video games. A controller unit is provided to users for operating video games on video game consoles, wherein the controller unit includes a keypad with a plurality of keys for controlling the operation of video games. Face plates are designed that are removably attachable to the controller keypad for operating different video games, wherein each face plate covers keys on the keypad that are unnecessary for controlling a particular video game, and the face plate provides an access code to the controller when attached to the keypad for accessing operation of the particular video game.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       [0025]    The preferred embodiment of the present invention provides a method and apparatus for controlling the operation of both a television and a video gaming system with a single remote controller unit. 
         [0026]    The present invention will now be described in more detail with reference to the figures.  FIG. 1  is a perspective view of remote controller unit  10  according to the preferred embodiment of the present invention. As shown, the remote control unit  10  includes a housing  11  and a base panel  12  with openings for receiving elastomeric pushbuttons for keypad  13 , extending therefrom. Face plate  14  overlays a portion of the base panel on the outer surface thereof. The function that is assigned to each pushbutton for controlling a television or another electronic audio/video component is labeled on the face plate. LEDs  15  and  16  transmit infra-red (IR) signals to control a television or other audio/video devices. 
         [0027]    An arrangement of pushbuttons for the remote control and the face plate label for controlling a television and other audio/video components is shown in greater detail in  FIG. 2 . As can be seen, pushbuttons  21  are grouped together as four buttons that are contiguous to one another as a set. Face plate  14  indicates that these pushbuttons control “channel up”  21   a , “channel down”  21   b , “volume up”  21   c , and “volume down”  21   d . Pushbuttons  21  can be used for controlling the volume and/or the channel of a television, radio receiver, or VCR. Pushbuttons  22  are also grouped together as four contiguous buttons located toward the lower side of the base panel  12 . These pushbuttons control “play”  22   a , “stop/eject”  22   b , “fast forward/scan forward”  22   c , and “rewind/scan reverse”  22   d . Pushbuttons  22  can be used for operating a VCR, a DVD player, or a CD player. 
         [0028]    The set of push buttons  23  control whether the remote control is operating in a mode for controlling the television (“TV”), video cassette recorder (“VCR”), compact disc player (“CD”), digital video disc player (“DVD”), or video game system (“Game”). As an alternative, a toggle control can be operated by a switch on the side of the remote controller unit. 
         [0029]      FIG. 3A  provides an orthogonal view of the remote controller unit  10 . The hand-held controller is held by a user in an upright or vertical position to control a television, VCR, CD player, or DVD player. When the remote controller is used for playing video games, it is held in the horizontal position as shown in  FIG. 3A , such that the width of the unit is greater than its height. As can be seen, one of the two sets of four contiguous pushbuttons  21 ,  22  can be utilized for manipulating the position of a character in a video game (up, down, left, right), and the other can be used to select the activities or events associated with the game (shoot, jump, select, etc.). Depending upon the configuration of the game or the game console design, other keys in the keypad (e.g., the pushbuttons for the “1”, “4”, and “7” keys) may also be activated for use when in the “game” mode. 
         [0030]    As shown in  FIG. 3B , the sides of the remote control unit when positioned in the horizontal position are ergonomically shaped to conform to the position of hands and fingers when playing a video game.  FIG. 3C  is a rear-side orthogonal view of the remote control. The indentations in the shape of the sides of the remote control and the bump-out in the center-edge of the remote control allow the unit to be held easily by a user in the orthogonal position. 
         [0031]      FIG. 4  provides a schematic diagram of the operating circuitry in the remote control unit according to the present invention. The electrical circuitry is generally of the type disclosed in O&#39;Donnell et al., U.S. Pat. No. 5,414,426, and in FIG. 9 of Darbee et al., U.S. Pat. No. 4,959,810, the disclosure of both of which are incorporated herein by reference. Remote control  10  includes a microprocessor  41 , which includes central processing unit (CPU)  42  and memory including RAM  43  and ROM  44 . Keypad  13  is connected to CPU  42  by an interrupt line  45   a  and a bus  45   b . A battery power supply  46  also connects to CPU  42 . Backup battery  47  maintains the data in RAM memory  43 . The output of the CPU  42  is connected to one or more LEDs and lamp drivers  48 , which transmits an infra-red signal to infra-red receivers on the electronic audio/video components to be controlled, as shown by LEDs  15  and  16  in  FIG. 1 . When the remote control held in a vertical position for use in controlling a television, VCR, DVD player, CD player, etc., the IR Lamp Driver Circuit  48  drives LED  49   a , located at the top edge of the remote control unit. When the remote control is held in the horizontal position for controlling a game console, the lamp driver  48  drives LED  49   b , which is located along the side edge of the remote control unit. The two LEDs are positioned such that the infra red light will be directed toward a receiver in an entertainment console unit. The relative positioning of the two LEDs,  51   a  and  51   b  on a circuit board  50  for a remote controller unit is shown in  FIG. 5 . 
         [0032]    The operating programs for the remote control  10  that are stored in RAM  43  and ROM  44  are similar to the operating programs disclosed in U.S. Pat. Nos. 4,959,810 and 5,414,426, with the exception of the video game operation and programming for selectively illuminating the operative keys, as will be described below. 
         [0033]    When a user presses the pushbutton  23  for “Game,” CPU  42  receives a signal to load the keypad configuration for the remote control unit from ROM  44  for the video game mode. As described with reference to  FIG. 3A , pushbutton sets  21  and  22  may be activated in this mode, and, depending upon the particular configuration, the pushbuttons for “1”, “4” and “7” also may be activated. Correspondingly, if pushbutton “2” is depressed in the video game mode, the CPU will ignore this activity. By holding the remote control in the orthogonal direction and using the selected subset of pushbuttons designated for the video game mode, a user can use the remote controller unit for playing video games or for participating in interactive television. On the right side of the controller, the pushbuttons of pushbutton set  21  are labeled “Up”  21   a , “Down”  21   b , “Left”  21   c , and “Right”  21   d , above the top of the pushbuttons. As can be seen, the commands for controlling a television, namely, “Channel Up,” “Channel Down,” “Volume Up,” and “Volume Down,” are now shown to the side of the pushbuttons. On the left side of the controller, the pushbuttons of pushbutton set  22  are labeled “Fire”  21   a , “Jump”  21   b , “Walk”  21   c , and “Run”  21   d , above the top of the pushbuttons. 
         [0034]    In a first alternative embodiment, the remote controller of the present invention selectively illuminates the pushbuttons that are operative for the designated mode. In the “game” mode, the only buttons that are illuminated are those for pushbutton sets  21  and  22 , and perhaps the pushbuttons for the “1”, “4”, and “7” keys. Assuming that the remote control is being used in a darkened room, only the illuminated keys will be viewable by the user. Even in a normally lighted room, the illuminated keys will be more easily viewable by the user. 
         [0035]    The configuration of LEDs for selectively illuminating a subset of the pushbuttons on the remote control is shown in  FIG. 5 . The remote controller unit is constructed of a circuit board  50 , an insulating plate/light separator  55 , a contact plate  58 , a pushbutton plate  60 , a lower housing  62  and an upper face plate  65 . Above the lower housing casing  66 , circuit board  50  is imprinted with a plurality of contacts  53  that are positioned directly beneath the remote control pushbuttons. The circuit board additionally includes four LEDs,  54   a ,  54   b ,  54   c , and  54   d , which protrude from the circuit board and are connected with lighting circuits on the circuit board. The circuit board additionally includes an LED  51   a  at the tip of the remote control unit and a second LED  51   b  at a side edge of the unit, each for transmitting IR signals to a receiver. 
         [0036]    An insulating plate  55  with holes  56  is positioned directly above the circuit board  50 . The insulating plate includes three separator walls,  57   a ,  57   b , and  57   c . The separator walls surround a subset of the plurality of holes  56 , and block any light emitted from LEDs  54   a ,  54   b ,  54   c , and  54   d  from penetrating beyond the holes encircled by the walls. Contact plate  58  is positioned directly above the insulating plate  55  and has a plurality of contacts  61  to electrically contact with contacts  53  on the circuit board  50 . 
         [0037]    A translucent pushbutton projection fixing, locating or guiding plate  60  with holes  61  is positioned above the contact plate  58 . Transparent or translucent plate  62  is then seated on the pushbutton fixing plate  60 , and has a plurality of pushbutton protrusions  63  that extend upwardly through holes in the upper casing  65 . 
         [0038]      FIG. 6  is a schematic diagram of the microprocessor  41  of  FIG. 4  with additionally connected circuitry for providing illumination within the remote controller unit  10 , for use in an alternative embodiment of the present invention. When the pushbutton marked as “Games” is depressed on keypad  13 , contact  66  electrically contacts the corresponding contact on the circuit board, sending a signal through interrupt line  45   a  and bus  45   b  to CPU  42  to load the “game mode” configuration from ROM  44 . CPU  42  then retrieves an instruction from CPU  42  to drive a subset of LED backlights  68   a ,  68   b ,  68   c , or  68   d  to illuminate activated pushbuttons that correspond with the “game mode.” Because the separator walls  57   a ,  57   b , and  57   c , on the insulating plate  55  prevent the light emitted from the LEDs from penetrating beyond the selected pushbuttons, the remote controller unit  10  of an alternative embodiment present invention selectively illuminates only those pushbuttons  63  that are activated for the “game mode.” 
         [0039]    It is also possible to configure CPU  42  and ROM  44  to send instructions to illuminate only certain pushbuttons when the remote controller unit is used in other modes. For example, the pushbuttons for “play”  22   a , “stop/eject”  22   b , “fast forward”  22   c , and “rewind”  22   d , are not active when the remote control is used to control the features of a television. Accordingly, the remote control can be configured such that these translucent push buttons are not illuminated when the remote control is in the “TV” mode. 
         [0040]    As another alternative embodiment, the remote controller unit can include an LCD display above or beside each pushbutton, and can be programmed to display a descriptive indicator for each pushbutton that is activated. The LCD display can be backlit for clearer illumination in a darkened room. The LCD display may be used in conjunction with a series of push-buttons (e.g., above or below the actual buttons), or may be used as a display beneath a touchscreen surface, to be operated by pressing fingers against the screen or a special pointer device, as in many conventional personal digital assistant devices (PDA&#39;s) such as the Palm Pilot™ systems. 
         [0041]      FIGS. 7A ,  7 B, and  7 C provide an illustration of a remote control unit configured within a multi-function, personal digital assistant. As shown in  FIG. 7A , the LCD display provides a touch screen display for a television/VCR remote control, to be operated in the upright position. In  FIG. 7B , different text is displayed within the LCD display, perpendicular to the text displayed in  FIG. 7A  to control a game console when the unit is held in the horizontal position.  FIG. 7C  illustrates an example in which different text is provided on the left-side of the display for use in controlling the operation of a different type of game. In this “karate” game, the “fire,” “walk,” and “run” input keys are replaced with “duck,” “kick,” and “punch.” 
         [0042]    As an alternative embodiment to selectively illuminating the activated pushbuttons, the remote control system can be designed to be fitted with removable face plates that expose only the activated pushbuttons for particular modes of operation for the remote control.  FIG. 8  illustrates a removable face plate  80  to be affixed to remote control  10 . As can be seen, the face plate  80  has a plurality of holes  81  that expose pushbuttons for only a selected subset of pushbuttons on remote control  10 . The face plate  80  also contains text or graphics imprinted above or beside the holes to indicate the purpose or function of the exposed push buttons when in operation. The face plate  80  connects to the remote control  10  through a series of connectors  82 , which attach to slots  83  at both sides of the remote control  10  on the housing such that the face plate is removably affixed to the remote controller unit. Accordingly, when the face plate  80  is attached to the remote control  10 , the remote control appears such that the remote control is designed exclusively for use for the video gaming system. 
         [0043]    In another alternative embodiment, the face plate  81  can have a protrusion on the underside of the face plate body, shown in phantom lines as element  84 , to press against the “Games” pushbutton  85  and load the ROM  43  code for activating the pushbuttons for controlling the game console. In such a system, the CPU may be configured to require the “Games” pushbutton to be continually depressed, as would occur when the face plate  80  is affixed to the remote control unit  10 . 
         [0044]    Face plates can also be designed to be interchangeable to accommodate the play of different types of games in the game console. For example, while the face plate shown in  FIG. 8  may be appropriate for a “karate” or martial arts-type of action game, the “jump,” “kick,” “duck,” and “punch” keys may not be appropriate for other types of games. Therefore, a different type of face plate may be available for purchase for each type of video game. 
         [0045]      FIG. 9A  provides an illustration of a face plate that may be suitable for play for a driving/racing-type of game. Some of the pushbuttons that are active for the “karate” game illustrated with reference to face plate  80  in  FIG. 8  are not utilized for the racing game that uses face plate  90 . The face plate  90  is also labeled differently to reflect the differences in how the game is played.  FIG. 9B  provides another illustration of a face plate that is suitable for playing a different type of game. In this case, face plate  91  is configured for playing a television-style quiz-show. 
         [0046]    Face plates  90  and  91  as shown in  FIGS. 9A and 9B  additionally include a series of protrusions on the underside of the face plate body, in addition to the protrusion  84  that depresses the “Games” pushbutton when connected to the remote controller unit. These additional protrusions may serve two possible purposes. These protrusions may activate a code to the CPU  42  to indicate the type of game that is to be played, so that the CPU can retrieve the appropriate code from memory to activate the proper pushbuttons. Secondly, the code may required by the CPU as an access mechanism. By requiring a code, a user can only play game for which he has the appropriate face plate. In this manner, the game manufacturer can reduce the instances of software piracy, by requiring a user to purchase a face plate before playing a game. 
         [0047]    Accordingly, the remote controller unit of the present invention allows a user to control a television, several other types of electronic audio/video equipment, and a game console, all with a single remote controller unit. The pushbuttons on the remote controller unit can be selectively illuminated to indicate the pushbuttons that are activated in each mode of operation of the controller. The remote controller unit can also be configured within a touchscreen LCD display, in which the text within the graphical keypad changes for each mode. Finally, the remote controller unit can be configurable with one or several types of removably fixable face plates. These face plates can indicate the assignment of particular push buttons on the remote controller unit for a game, and provide an access code required by the CPU in order to gain access and play a game. 
         [0048]    The foregoing disclosure of embodiments of the present invention and specific examples illustrating the present invention have been presented for purposes of illustration and description. It is not intended to be exhaustive or to limit the invention to the precise forms disclosed. Many variations and modifications of the embodiments described herein will be obvious to one of ordinary skill in the art in light of the above disclosure.
