VIDEO GAME CONTROLLER WITH LIGHT FEEDBACK MECHANISM
BACKGROUND OF THE INVENTION
[0001] This invention relates to video game controllers, and more particular to video game controllers having a feedback feature that controls lights in the controller depending on the actions taking place in the game being played.
[0002] Video games, such as those that run on popular video game platforms such as Microsoft® XBox®, Sony® Playstation®, and Nintendo® GameCube® all include a game console unit that plays games stored on CD ROMs or DVDs. The game console unit connects to a video display, most commonly a television set, plasma display, etc. Connected to the console unit, either by cables or by a wireless connection, are game controllers with buttons, joysticks and/or other actuating devices. Some of the older styles of game consoles use replaceable game cartridges instead of CD ROMs or DVDs as the media for the games, but nonetheless, each employ a game controller for interfacing between the game and the player.
[0003] A game controller may incorporate what is termed a "force-feedback effect" or
"rumble" feature, to cause the controller to vibrate in response to actions taking place in the game being played. This helps to provide tactile feedback to a player holding and using the game controller. For example, a player may feel feedback when tackled by an opposing linebacker, when cornering hard or crashing in a driving game, or shooting a shotgun. The vibration is generally generated by vibration/feedback motors that are controlled by circuitry which translate action in the game to activity at the motor(s) that causes a vibration or movement in the controller. The operation of these motor(s) consumes electricity at a relatively high rate compared to other features of the controller. In the case of wired controllers which derive their power from the console, the issue of power consumption is not of great concern. However, in the case of wireless devices which are powered by onboard batteries, battery life may be shortened due to the use of the rumble feature.
[0004] There are also game controllers which incorporate internal lights (e.g. different colored LEDs) inside a clear plastic body of the game controller. These lights provide a more
interesting visual appeal to users when the game controller is in use. Since LED lights consume moderate amounts of power, use of LED lights does not place great additional power demands on wireless devices. In some cases, these lights remain statically lit. In other cases, the lights may randomly flash or flash in some predetermined pattern. However, the lights in these prior art game are not controlled based on feedback from the player's interaction with the game. It would be appealing for feedback from the player's interaction with a game to be visually appreciated at the game controller in lieu of or in addition to being provided by a rumble feature.

1 DETAILED DESCRIPTION OF THE INVENTION
[0016] In general terms, an embodiment of the present invention provides a wireless and/or wired video game controller with one or more light sources coupled to a rumble/vibration circuitry included in the controller. The lights from the light sources provide visual feedback to a player for actions occurring in a game that is being played. In the case of a wired controller, the lights that provide the visual feedback may be included in addition to vibration motor(s), which provide tactile feedback to the player. In the case of a 10 wireless controller, the rumble motor(s) may be eliminated for purposes of limiting power consumption. In this case, only lights are provided to provide visual feedback. The visual feedback may be in terms of flashing lights, stationary lights, or other types of light display
1 - mechanism that should be appreciated by a person of skill in the art. Furthermore, one portion of the game controller may display one light color while another portion of the game controller may display a different light color. Furthermore, the portions of the game controller that may be lit may differ depending on the actions taken during the game.
20 [0017] FIGS. 1A-1D are top perspective views of various exemplary video game controllers 100a- lOOd according to one embodiment of the invention. FIG. IE is a side perspective view of an exemplary video game controller lOOe according to one embodiment of the invention. Each illustrated controller includes a housing 102 which has all or portions
25 made of a transparent or translucent material to allow one or more lights inside the housing to shine through. The lights may be controlled to cause the housing to appear in a particular color, and/or to cause the housing to display a particular pattern or color pattern. According to one embodiment, the transparent portions of the housing are laid out in such a manner that 30 when one or more lights inside the housing are lit, they provide a crackle-type paint effect on the housing. Alternatively, the crackle-type paint effect may be provided by the layout of the light sources inside the housing. The crackle-type paint effect may be provided in a single or ox- multiple stationary and/or flashing colors.
[0018] Although the lights are described as residing inside the housing of the game controller, a person of skill in the art should appreciate that all or portions of the lights may also be located outside of the housing.
[0019] According to another embodiment of the invention, in lieu or in addition to the lights, digital ink may be employed on the housing 102 to cause the display of particular shapes, patterns, or letters.
[0020] FIG. 2 is a block diagram of a wireless game controller 1OA with a light feedback 10 mechanism according to one embodiment of the invention. The wireless controller 1OA connects to a video game console 12A with a wireless interface, such as, for example a radio frequency (RF) interface 14. The video game console 12A is in turn connected to a monitor
1 - 16A which may be, for example, a plasma display, television monitor, computer monitor, or the like.
[0021] The video game console 12A includes a memory 32A storing computer program instructions which, when executed by a processor 36A, cause the processor to interact with a
20 disc or cartridge reader 34A to read game software for playing a game. The game software may be provided on a CD, DVD, memory cartridge, or any storage device conventional in the art. The game console 12A may also be equipped with a network connection (not shown) for downloading the game software into the memory 32A over a wired or wireless local area network, a private wide area network, or a public wide area network such as the Internet. [0022] The game software communicates with the game console 12A to display text, graphics, and/or video associated with the game. The game software also communicates with the wireless game controller 1OA to receive user input that controls the progression of the 30 game. The game software further transmits to the game controller signals used by the controller to provide visual feedback to the player in response to actions taken during the game.
„<- [0023] In the illustrated embodiment, the wireless game controller 1OA has a wireless transponder, such as, for example, an RF chip 18. The RF chip 18 is connected to an interface chip 2OA, which in turn is connected to one or more rumble/vibration chips 22A,
22B. The rumble chips 22 A, 22B may be similar to the rumble chips provided in game controllers manufactured for Sony® PlayStation® 2, Microsoft® Xbox®, and Nintendo® GameCube® video game consoles. However, instead of using the output of the rumble chips to control rumble/vibration motors to provide a rumble/vibration feeling in the controller during game play, the rumble chips 22A, 22B in the illustrated embodiment are used for controlling one or more light sources, such as LEDs 22 A, 22B, 24A, and 24B. In this regard, the rumble chips 4OA, 4OB are coupled to the LEDs 22 A, 24A, 22B, and 24B, and each time the game software triggers the rumble chips 4OA, 4OB, one or more of the LEDs are actuated in response. As an example, in a game where guns are being fired, one or more LEDs may be actuated to flash a light each time the player's character fires or gets fired upon. Because the light sources consume less power than the rumble/vibration motors, power may be preserved while allowing feedback to the player.
[0024] The LEDs 22A, 22B, 24 A, and 24B may be different colors (or multicolor) LEDs for added visual impact, with, for example, different color effects being produced in response to different signals from the rumble chips 4OA, 4OB. Just by way of example, a red LED may flash in response to a "gun fire" signal from the rumble chips while a while a white LED may flash in response to a "lightning" signal from the rumble chips.
[0025] According to the illustrated wireless embodiment, an on-board power supply, such as batteries 28, supply power for the wireless controller 1OA. Various input devices 3OA such as buttons, switches, joysticks, mouse pad, voice and/or motion activation units, and the like are coupled to the interface chip 2OA for allowing a user to interact with the game.
[0026] FIG. 3 is a block diagram of a wired game controller 1OB with a light feedback mechanism according to one embodiment of the invention. The wired game controller 1OB is coupled to a game console 12B which in turn connects to a game monitor 16B similar to the game monitor 16A of FIG. 2. The game console 12B includes a processor 36B, memory 32B, and disc or cartridge reader 34B which may be similar to the processor 36A, memory 32A, and disc or cartridge reader 34A of FIG. 2.
[0027] The wired game controller 1OB includes an interface chip 2OB coupled to input devices 30B and one or more rumble chips 4OC, 4OD. The rumble chips 4OC, 4OD are in turn coupled to one or more light sources, such as LEDs 22C, 22D, 24C, 24D. The interface chip 5 2OB, input devices 3OB, rumble chips 4OC, 4OD, and LEDs 22C, 22D, 24C, 24D are similar to the interface chip 2OA, input devices 30B, and rumble chips 4OA, 4OB, and LEDs 22 A, 22B, 24A, 24B of FIG. 2.
[0028] Unlike the wireless embodiment of FIG. 2, however, the wired controller 1OB in 10
FIG. 3 derives its power from the video game console 12B via a power cable 42 instead of a battery. Thus, unlike the wireless embodiment where no vibration motors are included to limit power consumption, the wired embodiment includes one or more vibration motors 26A,
1 - 26B to provide a rumble/vibration effect. The rumble chips 4OC, 40D according to this embodiment are coupled to the vibration motors 26A, 26B as well as to the LEDs 22C, 22D, 24C, 24D. The rumble/vibration motors interact with the game software to provide a rumble/vibration feeling in the controller during game play. Some common examples
20 include the feedback a player feels when being tackled by an opposing linebacker in a football game, when cornering hard or crashing in a driving game, or shooting a shotgun and feeling its tactical kick. However, because the rumble chips 4OC, 4OD are also coupled to the light sources, a signal emanating from the rumble chips 4OC, 4OD in response to the player's interaction with the game not only causes the rumble motors 26A, 26B to be activated, but also causes the activation of the LEDs to create a complementary light flashing or stationary light feature. The lights provide visual appeal and feedback in addition to the tactile feedback from the rumble motors 26 A, 26B. 30
[0029] A person of skill should appreciate that in addition to the use of the rumble chips
4OA, 4OB, 4OC, 4OD (collectively referenced as 40), other chips or devices may be used in lieu or in addition to the rumble chips to provide the visual feedback to the player. For „ - example, the various light sources may be coupled to one or more speaker units (not shown) included in the controller or game console to activate the lights in response to certain types of audio output. The light sources may also be directly coupled to the control buttons, switches,
and the like to cause different lights to shine or flash in response to the actuation of different control buttons, switches, and the like. Furthermore, the interface chip 2OA, 2OB may be programmed to control the light sources directly, allowing the lights to be activated even when the rumble chips are not activated.
[0030] FIG. 4 is a process flow diagram of a game controller light feedback mechanism according to one embodiment of the invention. The process may be a software process, portions of which is executed by the processor 36A, 36B and portions of which is executed by the interface chip 2OA, 2OB. A person of skill of art should recognize, however, that the process may be implemented via hardware, firmware, or a combination of hardware, firmware, and/or software. Furthermore, the various steps of the process may be implemented in the indicated order, or in any other order that should be appreciated by a person of skill in the art.
[0031] In step 200, the interface chip 2OA, 2OB receives a player's actuation of the input device 36A, 36B for controlling the progression of the game. In step 202, the user input is transmitted to the game software executed by the processor 36A, 36B in the game console 12A, 12B. The game software processes the user input in step 204 and provides one or more output signals in response. A portion of the output signals are transmitted to the game console to control the display on the game monitor 16 A, 16B. Other portions of the output signals are transmitted to the game controller 1OA, 1OB and processed by the interface chip 2OA, 2OB in step 206. The portion of the output signal processed by the interface chip may be a feedback signal indicative of a type of feedback to provide to the player in response to the user action taken or a particular occurrence in the game.
[0032] In step 208, the interface chip transmits a rumble signal corresponding to the feedback signal to the rumble chips 22. The rumble chips 22 are then actuated to control any rumble motors that may be coupled to the rumble chips 22. Because the rumble chips 22 are also coupled to the LEDs 22A-D, 24A-D, one or more LEDs are also actuated in step 210 each time the rumble chips are actuated to provide visual feedback to the user. The rumble signal controls which LEDs are actuated as well as other LED lighting parameters such as,
for example, the length of time in which they are actuated, the brightness of the lights, the timing of the actuation, and the like.
