## Background
RELATED APPLICATION
This application is a continuation of and claims priority to the U.S. patent application assigned Ser. No. 11/566,615, filed Dec. 4, 2006 now abandoned, and titled “Game Controller Simulating Musical Instrument.”


FIELD OF THE INVENTION
This invention relates to video game controllers and, more particularly, to video game controllers that emulate a musical instrument to provide game input.
BACKGROUND OF THE INVENTION
“Rhythm-action” is a popular video game genre which requires a player to perform phrases from a pre-recorded musical composition using the video game's input device. One of the best-known examples of this genre is the BEATMANIA series of games published by Konami Co. Ltd. of Japan. In this series of games the notes in musical phrases are graphically displayed to the player as a series of visual markers spaced along one or more timelines; each marker corresponds to one note in the phrase. In the block diagram environment shown in FIG. 1, visual markers 104 move from the top of the display to the bottom of the display. As each marker on the scrolling timelines 110, 120, 130, 140 passes a graphical cursor 108 displayed along this timeline, the player must simultaneously press a button on an input device (not shown) corresponding to the correct timeline to play the sound of the corresponding note at the correct time. If the player performs this action successfully for a sufficient percentage of the notes, he scores well and wins the game. If the player fails to perform this action successfully for a sufficient percentage of the notes, he scores poorly and loses the game. As shown in FIG. 1, two or more players may compete against each other, typically by each one attempting to play back different, parallel musical phrases from the same song simultaneously. The player who plays the highest percentage of notes correctly achieves the highest score and wins.
It is known, in the context of some rhythm-action games, to provide game controllers simulating musical instruments that allow players to fully use both their right and left hand to provide game input. It would be desirable to provide a game controller that closely mimics the instrument which the controller simulates in such a way that the physical instrument features mimicked by the controller affect gameplay.
SUMMARY OF THE INVENTION
In one aspect, the present invention relates to a guitar game controller which comprises two pluralities of fret buttons. A player switching between the pluralities of fret buttons during gameplay may trigger special game effects, graphics. In one embodiment, the present invention is a game controller simulating a guitar including: a body portion including a strum bar; a neck portion extending outwardly away from the body portion; a first plurality of fret buttons disposed on the neck portion; and a second plurality of fret buttons disposed on the neck portion. The game controller may also have a vibrato bar. The pluralities of fret buttons may each comprise five fret buttons. In some embodiments, a fret button in the first plurality fret buttons may correspond in color and/or function to a fret button in the second plurality of fret buttons. The second plurality of fret buttons may be used to trigger guitar effects such as a pick slide, a screech and feedback.
In a second aspect, the present invention relates to using a guitar having two pluralities of fret buttons in conjunction with a music-based video game. In one embodiment, the present invention is a method for facilitating interaction of a player with a music-based video game using a game controller simulating a guitar, which includes: providing a game controller comprising a body portion having a strum bar and a neck portion extending outwardly from the body portion and including a first plurality of fret buttons and a second plurality of fret buttons; displaying to a player first target musical data associated with a musical composition; receiving first music performance input from the player using one of the first plurality of fret buttons; displaying to the player second target musical data associated with the musical composition; and receiving second music performance input from the player using one of the second plurality of fret buttons. In other embodiments, the method relates to displaying special musical targets relating to a guitar solo, the targets signifying to the player that the solo should be played on a second set of fret buttons. The method may also include altering gameplay characteristics and/or graphics in response to the player successfully executing the solo on the second plurality of fret buttons.

DETAILED DESCRIPTION
A controller simulating a musical instrument may be used with a variety of gaming platforms, such as: PLAYSTATION2, PLAYSTATION3, or PLAYSTATION PERSONAL, manufactured by Sony Corporation; DREAMCAST, manufactured by Sega Corp.; GAMECUBE, GAMEBOY, GAMEBOY ADVANCE, OR WII, manufactured by Nintendo Corp.; or XBOX or XBOX360, manufactured by Microsoft Corp. In other embodiments, the simulated guitar musical controller may be used with a gaming platform comprising a personal computer, personal digital assistant, or cellular telephone.
Although described below in connection with a simulated guitar controller, the game controller may simulate any of a wide variety of musical instruments such as percussion instruments (including cymbals, bell lyre, celeste, chimes, crotales, glockenspiel, marimba, orchestra bells, steel drums, timpani, vibraphone, xylophone, bass drum, crash cymbal, gong, suspended cymbal, tam-tam, tenor drum, tom-tom, acme siren, bird whistle, boat whistle, finger cymbals, flex-a-tone, mouth organ, marching machine, police whistle, ratchet, rattle, sandpaper blocks, slapstick, sleigh bells, tambourine, temple blocks, thunder machine, train whistle, triangle, vibra-slap, wind machine, wood block, agogo bells, bongo drum, cabaca, castanets, claves, conga, cowbell, maracas, scraper, timbales, kick drum, hi-hat, ride cymbal, sizzle cymbal, snare drum, and splash cymbal), wind instruments (including piccolo, alto flute, bass flute, contra-alto flute, contrabass flute, subcontrabass flute, double contrabass flute, piccolo clarinet, sopranino clarinet, soprano clarinet, basset horn, alto clarinet, bass clarinet, contra-alto clarinet, contrabass clarinet, octocontra-alto clarinet, octocontrabass clarinet, saxonette, soprillo, sopranino saxophone, soprano saxophone, conn-o-sax, clar-o-sax, saxie, mezzo-soprano saxophone, alto saxophone, tenor saxophone, baritone saxophone, bass saxophone, contrabass saxophone, subcontrabass saxophone, tubax, aulochrome, tarogato, folgerphone, contrabassoon, tenoroon, piccolo oboe, oboe d'amore, English horn, French horn, oboe de caccia, bass oboe, baritone oboe, contrabass oboe, bagpipes, bugle, cornet, didgeridoo, euphonium, flugelhorn, shofar, sousaphone trombone, trumpet, tuba, accordion, concertina, harmonica, harmonium, pipe organ, voice, bullroarer, lasso d'amore, whip and siren), other stringed instruments (including harps, dulcimer, archlute, arpeggione, banjo, cello, Chapman stick, cittern, clavichord, double bass, fiddle, slide guitar, steel guitar, harpsichord hurdy gurdy, kora, koto, lute, lyre, mandola, mandolin, sitar, ukulele, viola, violin, and zither) and keyboard instruments (including accordion, bandoneon, calliope, carillon, celesta, clavichord, glasschord, harpsichord, electronic organ, Hammond organ, pipe organ, MIDI keyboard, baby grand piano, electric piano, grand piano, janko piano, toy piano, upright piano, viola organista, and spinets).
Game controllers simulating any of the instruments above may provide a note-producing mechanism different from that usually associated with the simulated instrument. For example, a simulated keyboard controller may include, in addition to key as one would expect on a keyboard, a pitch bend wheel or an associated effets pedal as a secondary note-producing mechanism. Simulated woodwind instruments may include “mutes,” such as cup mutes, straight mutes, wah-wah mutes, plunger mutes, bucket mutes, or hat mutes. A simulated microphone may include an effects pedal as a secondary note producing mechanism.
Referring now to FIG. 2, an embodiment of a simulated guitar controller 200 for use with a video game is shown. The simulated guitar controller 200 is provided with fret buttons 220. Although five fret buttons are shown in FIG. 2, any number of fret buttons 220 may be provided by the controller 200. The simulated guitar controller also includes a “strum bar” 240. In order to successfully “play” a game event, the player holds down one or more of the fret buttons 220 while simultaneously strumming the strum bar 240, in much the same way that one would play a guitar. In some embodiments players may also execute “hammer ons” and “pull offs,” as described below, which allows a player to “play” a game event by pressing or releasing only a fret button 220.
FIGS. 2A and 2B depict alternate embodiments of the guitar controller of FIG. 2. FIG. 2A depicts an embodiment of the guitar controller intended to simulate a guitar model by Gibson known as the “Flying V.” FIG. 2B depicts an embodiment of the guitar controller intended to simulate a guitar model known as the “Moderne.” Any other body styling may be provided.

The body portion of the guitar may simulate bass guitars, such as the Gibson EB-0, GIbson EB-1, Gibson EB-2, Gibson EB-3, Gibson EB-6, Gibson RD bass, Gibson Thunderbird, Gibson Ripper, Gibson Grabber, Gibson G3, Gibson Victory Standard bass, Gibson Les Paul bass, Fender Jazz Bass, Fender Jaguar Bass, Fender Mustang Bass, Fender Precision Bass, Fender Performer Bass, Fender Telecaster Bass, Fender VI, Fender Zone Bass, Fender Dimension Bass, Fender Bass V, Fender Bronco Bass, or Fender Bullet Bass.
FIG. 2C depicts another alternate embodiment of the guitar controller having two sets of fret buttons 220, 220′. As shown in FIG. 2C a second set of fret buttons 220′ is disposed on the “neck” of the guitar proximal to the guitar body, i.e. in between the first set of fret buttons 220 and the guitar body. In some embodiments, the ordering of the second set of fret buttons 220′ is the same as the first set of fret buttons 220; that is, if the first set of fret buttons 220 are colored, beginning at the “head” of the guitar neck and moving toward the body, green, red, yellow, blue, orange, then the second set of fret buttons 220′ have the same coloring as one continues down the neck toward the guitar body.
In some embodiments, the fret buttons 220 and 220′ may be colored to indicate that the buttons correspond to a particular note, chord, or fret. In some embodiments, a fret button 220 may indicate color by the color of the entire fret button. In other embodiments, only a portion of the fret button may be colored. For example, a fret button may be mostly black, but contain a colored dot or stripe indicating color. Or for example, the fret button may be clear, and one or more lights underneath the fret button may indicate the color.
In other embodiments, other markings on the neck may indicate the “color” of a particular fret button. For example, colored dots may be placed on the neck of the guitar next to one or more fret buttons 220 indicating the color corresponding to the fret button. In another example, patterns of dots may be used to indicate the note, chord, or fret to which a given button corresponds, similar to the patterns of dots used on traditional guitars to designate frets by thirds and octaves. In these embodiments, the fret buttons themselves may be white, clear, black, or all colored a similar color. In still other embodiments, one set of fret buttons 220 may be colored, while a second set of fret buttons is colorless. For example, in an embodiment such as the one shown in FIG. 2F, only one of the two fret buttons disposed on a given fret may be colored.
In some embodiments, a user of a guitar controller may be able to change the colors corresponding to one or more fret buttons, such as by using stickers, removable button colors, multiple colored LED's under the fret buttons, or otherwise. A game using the guitar controller may then have a configuration tool such that the user can configure the game to recognize the altered colors.
Although shown in FIG. 2C as round buttons, fret buttons 220′ may be any shape or size, including the same shape and size of the first set of fret buttons 220.
Referring ahead to FIG. 2F, the second set of fret buttons 220′ may be positioned on the neck portion of the guitar controller such that respective ones of the first set of fret buttons and corresponding ones of the second set of fret buttons are positioned on the same fret of the neck (i.e. a red fret button of the first set of buttons 220 and a red fret button of the second set of first buttons 220′ are located near each other on the same “fret” of the neck portion of the guitar controller). In specific ones of these embodiments, fret buttons are physically connected to a toggle switch which allows a single physical button to provide two fret buttons, one associated with a first set of fret buttons and one provided with a second set of fret buttons. In further embodiments, respective ones of the first set of fret buttons 220 and corresponding ones of the second set of fret buttons 220′ are electrically connected, e.g. wired together, so that activation of either one of the respective fret buttons is identified by the controller as activation of the fret button, regardless of whether the fret button from the first set of fret buttons 220, the fret button from the second set of fret buttons 220′, or both, are activated. In still other embodiments, the respective ones of the fret buttons are not wired together, that is, the controller can distinguish between activation of fret buttons in one set versus activation of fret button in another set.
In some of these latter embodiments, the second set of fret buttons 220′ may be used for playing “solos” during gameplay. Use of the guitar controller in this manner provides a player with a more realistic gameplay experience, since guitar solos are often played very close to the body of the guitar. In some embodiments, the second set of fret buttons 220; may be the only set of fret buttons on which hammer-ons and pull-offs may be executed, as described below. In other embodiments, the second set of fret buttons 220′ may be used to trigger specific guitar effects, such as pick slides, screeches, or feedback. Alternatively, “performing” using the second set of fret buttons may alter game graphics (such as venue animation, venue lighting, crowd animation, brightness, avatar animation, game cue sustain tail, game cue brightness, game cue sustain tail brightness, game cue size, game cue shape, game cue sustain tail pulsation, and game cue sustain tail size), sound quality, or other gameplay characteristics, such as character health, character wealth in the game, the player's score, or in-game “powerups.”
Referring back to any one of FIGS. 2, 2A, 2B and 2C, the simulated guitar controller 200 also includes a vibrato bar 260, also known to guitar players as a tremolo bar or “whammy bar.” The vibrato bar 260, for convenience, will be referred to throughout the remainder of this document as a “whammy bar” The whammy bar 260, as will be described below, may be used to alter the frequency, pitch, volume, sound quality, distortion, simulated feedback sound, or any other attribute of the current note or chord being played by the player.
The whammy bar 260 of the controller resembles a whammy bar of a real guitar. As shown in FIG. 2D, and with comparison to FIG. 2B, the whammy bar 260 can be rotated to any one of a number of positions for the convenience of the player. As shown in FIG. 2D, the whammy bar 260 has been rotated to a position that places it out of the way of the player's strumming hand. In some embodiments, the whammy bar 260 is spring-loaded, like the whammy bar of a real guitar. In these embodiments, as depicted by FIG. 2E, the whammy bar 260 can be pushed down or pulled up to affect the played note. When released, it settles back to its default, neutral position.
The whammy bar is typically manipulated by the guitarist's strumming hand, that is, the hand with which the player operates the strum bar 240. In a real guitar, manipulating the whammy bar directly affects the tension of the guitar strings, and therefore causes the pitch of the vibrating strings to rise and fall as the bar is pulled or pushed. The simulated whammy bar of the guitar controller, the vibrato bar, can be used as a continuous controlling actuator, much like a joystick. Typically, the vibrato bar has a single degree-of-freedom, but it may have more degrees of freedom. It may additionally be used as an on-off switch, instead of a continuous controller. The whammy bar 260 of the controller looks and feels like the whammy bar of a real guitar, and, therefore provides a much more enjoyable gaming experience for the player.
The guitar controller 200 also allows a player to use more sophisticated guitar playing techniques to interact with a game. Two such techniques are “hammer ons” and “pull offs.” Hammer-ons and pull-offs allow a guitarist to player notes in rapid succession. Typically, they only require the use of the player's fretting hand. To play a hammer-on note, the guitarist uses one of the free fingers of his fretting hand to strike the guitar string with high velocity. This results in the string vibrating due to the force of the string hitting a fret. As a result, the string need not be strummed by the strumming hand. Pull offs require the guitarist to tug slightly on the string when he releases it from a fret. This pulling action also causes the string to vibrate more, again, eliminating the need to strum the string with the strumming hand.
In the simulated guitar controller 200, hammer-ons may be simulated by allowing the player to press down fret buttons 220 without needing to simultaneously strum the strum bar 240. This is achieved by the manufacturer of the game authoring the game content to identify a note as amenable to hammering on or pulling off. For a hammer on, a player will generally need to capture a “lower” pitched note traditionally, that is, by holding down a fret button and simultaneously activating the strum bar. If the next note is identified as amenable to being played by a hammer technique, the player need only activates the “higher” pitched fret button to successfully capture the note.
Similarly, in pull-offs, the player can “play a note” by releasing a fret button 220 without needing to simultaneously strum the strum bar 240. This is achieved, again, by the manufacturer of the game authoring the game content to identify a note as amenable to hammering on or pulling off. For a pull off, a player will generally need to capture a pair of notes traditionally, that is, by holding down both fret buttons and simultaneously activating the strum bar. If the next note is identified as amenable to being played by a pull off technique, the player need only release the “higher” pitched fret button to successfully capture the note. As discussed above, when using the embodiment of a guitar controller 200 depicted in FIG. 2E, the second set of fret buttons may be used to perform hammer-ons and pull-offs. In either of these embodiments, notes that may be played using a hammer-on or pull-off technique may be visually indicated to the player by, for example, changing their geometric shape, transparency, color, or brightness.
Real guitarists often perform flamboyant motions on stage when playing guitar as part of their showmanship. One typical motion involves rotating the guitar vertically so that the neck of the guitar points up, while the body of the guitar is down, usually at waist level. In the simulated guitar controller 200, a mechanical “tilt sensor” can be included that monitors the guitar's physical orientation. This tilt sensor is typically a mercury switch or a ball-bearing switch which acts as a binary actuator, indicating whether the guitar has been rotated into a “neck up” position, or is in the normal playing position. Such tilt sensors have been included in guitar controllers manufactured by Konami and by Red Octane. Other secondary techniques for interacting with the controller include shaking the controller and slapping the controller.
Referring now to FIG. 3, one embodiment of a screen shot depicting a rhythm action game in which the simulated musical instrument, such as a simulated guitar controller, can be used is shown. A lane 320 extends to the players. In the embodiment shown in FIG. 3, the lane has five sub lanes 322, 324, 326, 328, 330 which correspond to a respective one of the fret buttons 220 provided on the guitar controller 200. In other embodiments, the number of sublanes does not need to match the number of fret buttons 220 provided by the simulated guitar controller 200. For embodiments in which there are more fret buttons 220 provided than sublanes, a subset of the provided fret buttons 220 may be used to interact with the game. For those embodiments in which there are more sublanes than fret buttons 220, one fret button 220 may be assigned to more than one sublane.
As shown in FIG. 3, each lane may be subdivided into a plurality of segments. Each segment may correspond to some unit of musical time, such as a beat, a plurality of beats, a measure, or a plurality of measures. Although the embodiment shown in FIG. 3 show equally-sized segments, each segment may have a different length depending on the particular musical data to be displayed. In addition to musical data, each segment may be textured or colored to enhance the interactivity of the display.
Referring back to FIG. 3, a sublane may have one or more game “cues”, “elements” or “gems” 350 corresponding to musical events distributed along the sublanes. During gameplay, the cues 350 appear to flow toward a game player. The cues 350 are distributed on the sublanes in a manner having some relationship to musical content associated with the game level. For example, the cues may represent note information (gems spaced more closely together for shorter notes and further apart for longer notes, pitch (gems placed on the left side of the lane for notes having lower pitch and the right side of the lane for higher pitch), volume (gems may glow more brightly for louder tones), duration (gems may be “stretched” to represent that a note or tone is sustained), articulation, timbre or any other time-varying aspects of the musical content. Although shown in FIG. 3 as a circular element, the game elements 350 may be any geometric shape, and may have other visual characteristics, such as transparency, color, or variable brightness.
As the game elements 350 move along a respective sublane, musical data represented by the game elements 350 may be substantially simultaneously played as audible music when the player successfully performs the event. To successfully perform an event, a player holds down the fret button 220 corresponding to the sublane on which the game elements 350 appears while strumming the strum bar 240. The player must perform this action when the game element 350 passes under the target marker 375. In some embodiments, the player may hold down the corresponding fret button at any point in time before the moment when game element 350 passed under the target marker 375. In other embodiments, the player may successfully perform an event by performing a hammer on or pull off when the game element 350 passes under the target marker 375.
In some embodiments, audible music represented by a game element 350 is only played (or only played at full or original fidelity) if a player successfully “performs the musical content” by capturing or properly executing the game element 350. In other embodiments, the audible music represented by a game element 350 is modified, distorted, or otherwise manipulated in response to the player's proficiency in executing game elements associated with a sublane. For example, various digital filters can operate on the audible music prior to being played by the game player. Various parameters of the filters can be dynamically and automatically modified in response the player capturing game elements associated with sublane, allowing the audible music to be degraded if the player performs poorly or enhancing the audible music if the player performs well. For example, if a player fails to execute a game event, the audible music represented by the failed event may be muted, played at less than full volume, or filtered to alter the its sound. In certain embodiments, a “wrong note” sound may be substituted for the music represented by the failed event. Conversely, if a player successfully executes a game event, the audible music may be played normally. In some embodiments, if the player successfully executes several, successive game events, the audible music associated with those events may be enhanced, for example, by adding an echo or “reverb” to the audible music. The filters can be implemented as analog or digital filters in hardware, software, or any combination thereof. Further, application of the filter to the audible music output, which in many embodiments corresponds to musical events represented by game elements 350, can be done dynamically, that is, during play. Alternatively, the musical content may be processed before game play begins. In these embodiments, one or more files representing modified audible output may be created and musical events to output may be selected from an appropriate file responsive to the player's performance.
FIG. 3A depicts a screenshot of an embodiment of a rhythm-action game in which a second set of fret buttons is part of gameplay. As shown in FIG. 3A and similar to FIG. 3, cues 350 appear to flow toward a game player. Unlike the embodiment depicted in FIG. 3, a second set of cues 355 are also distributed on the sublanes. The second set of game cues 355 indicate to the player that the second set of fret buttons 220′ should be used when performing those game events. In some embodiments, failure to perform those game events on the second set of fret buttons 220′ may result in failure. In other embodiments, successfully performing the game events indicated by the second set of game cues 355 may alter game graphics (such as venue animation, venue lighting, crowd animation, brightness, avatar animation, game cue sustain tail, game cue brightness, game cue sustain tail brightness, game cue size, game cue shape, game cue sustain tail pulsation, and game cue sustain tail size), sound quality, or other gameplay characteristics, such as character health, character wealth in the game, the player's score, or in-game “powerups.” Although the difference between game cues 350 and 355 is shown in FIG. 3 as geometric shape, the difference may be indicated using any visual characteristics, such as transparency, color, or brightness.
Referring now to FIG. 3B, a flow diagram illustrating one embodiment of a method for facilitating interaction of a player with a music-based video game using a game controller simulating a guitar is shown. In brief overview, the method comprises: providing a game controller comprising a body portion having a strum bar and a neck portion extending outwardly from the body portion and including a first plurality of fret buttons and a second plurality of fret buttons (step 301); displaying to a player first target musical data associated with a musical composition (step 303); receiving first music performance input from the player using one of the first plurality of fret buttons (step 305); displaying to the player second target musical data associated with the musical composition (step 307); receiving second music performance input from the player using one of the second plurality of fret buttons (step 309); and altering a gameplay characteristic in response to the received second music performance input (step 311).
Still referring to FIG. 3B, now in greater detail, the method shown comprises: providing a game controller comprising a body portion having a strum bar and a neck portion extending outwardly from the body portion and including a first plurality of fret buttons and a second plurality of fret buttons (step 301). The game controller may comprise a simulated guitar such as the one in FIG. 2C.
The method shown comprises displaying to a player first target musical data associated with a musical composition (step 303). This target musical data may comprise cues, elements, or gems as discussed herein. The first target musical data may indicate to the player that the player should use the first plurality of fret buttons 220 when playing the notes corresponding to the target musical data. For example, the first target musical data may correspond to a chorus or verse of a song which is meant to be played on the fret buttons 220 furthest from the body of the guitar. The method shown then comprises receiving first music performance input from the player using one of the first plurality of fret buttons (step 305).
The method shown comprises displaying to the player second target musical data associated with the musical composition (step 307). This target musical data may comprise cues, elements, or gems as discussed herein. The second target musical data may indicate to the player that the player should use the second plurality of fret buttons 220 when playing the notes corresponding to the target musical data. The second target musical data may differ from the first target musical data in shape, size color, transparency, and/or any other graphical property. For example, the second target musical data may correspond to a solo within a song that is meant to be played on the fret buttons 220′ close to the body of the guitar. The method then comprises receiving second music performance input from the player using one of the second plurality of fret buttons (step 309).
In some embodiments, the method comprises altering gameplay characteristics in response to the second music performance input (step 311). Examples of gameplay characteristics which may be altered include score bonus, star power, player score, character health, character money, in-game power-ups, and crowd excitement. For example, a player successfully playing a portion of a solo on the fret buttons 220′ close to the body of the guitar may result in increased crowed response, and an increased score. In other embodiments, the method comprises altering graphical characteristics of the game in response to the second musical performance input. Examples of graphical characteristics which may be altered include venue lighting, venue brightness, venue animation, crowd animation, crowd excitement, brightness, avatar animation, sustain tail, note brightness, sustain tail brightness, note size, note shape, sustain tail pulsation, and sustain tail size. For example, if a player successfully plays one or more notes using the fret buttons 220′ close to the body of the guitar, the notes may change color to indicate the success, and the crowd animation may be changed such that the crowd appears more enthusiastic about the performance.
Referring now to FIG. 4, one embodiment of a screen display showing player interaction using the whammy bar is shown. As described above, successfully activating the correct fret button 220 and strum bar 240 results in performance of a musical event. By activating the whammy bar, the player can alter the certain aspects of the reproduced musical event. For example, pushing or pulling on the whammy bar can change the pitch of a note or chord, the volume of a note or chord, or the sound quality of a note or chord. Activation of the whammy bar may also add effects to the audio such as simulated feedback, flange, fuzz, vocoder, echo, reverb, chorus, and delay. In some embodiments, pushing or pulling the whammy bar can add a feedback audio effect to a note or chord. In other embodiments, pushing or pulling the whammy bar can add a distortion audio effect to the note or chord being held. In addition, the whammy bar can affect sustained notes in addition to short single gems.
As shown in FIG. 4, pushing or pulling the whammy bar 260 may affect the graphical elements of the game. In FIG. 4, use of the whammy bar alters a note's “sustain trail,” a visual cue that helps a player know for how long a fret button should be depressed. As shown in FIG. 4, the player is using the whammy bar to alternately increase and decrease the width of the sustain trail. Other visuals can be directly affected by the whammy bar. The graphical display of the note may widen or narrow, it may brighten or dim, pulses can be animated down the length of the note, and its overall size may grow or shrink. Any number of graphical effects may alter the note to inform the player that the whammy bar is being actively used. In some embodiments, the player might be required by the game to move the whammy bar synchronously with a pitch bend in the recorded music. The player's moving of the whammy bar does not affect the sound, but the player's ability to bend the whammy bar as directed by the game affects the player's game score.
In other embodiments, use of the whammy bar may alter both the visual and auditory aspects of the game. For example, referring to FIG. 4, use of the whammy bar may cause the pitch of the sustained note to increase and decrease while the displayed sustain trail is widened and narrowed. In another embodiment, use of the whammy bar distorts a sustained note and causes a player's avatar to execute a flamboyant move, such as a jump, striking a pose with the guitar, or “machine gunning” the crowd with the guitar.
FIG. 5 depicts an embodiment of a screen display showing how use of the whammy bar may be used as a gameplay mechanic. In the screenshot shown if FIG. 5, the player is using the whammy bar to alter the pitch of a performed note. As shown in FIG. 5, the altered note is a special note indicating that the player will receive a bonus for successfully performing the note. By altering the note's pitch using the whammy bar, the player builds up the bonus more quickly. In one specific embodiment, the bonus is referred to as “star power collection” and is graphically indicated by the “star meter” 510.
In other embodiments, manipulating the whammy bar can affect other aspects of gameplay, such as the excitement of the simulated crowd, the number of points the player receives, the amount of “health” a player has, or, in general, the amount of any arbitrary game resource, such as points, score, health, money.
In some embodiments, the controller 200 may be used in conjunction with effects pedals that allow a player to activate certain audio effects. For example, a controller 200 may be provided with a socket for receiving input indicating activation of a flange pedal, fuzzbox, vocoder, distortion pedal, echo pedal, reverb pedal, chorus pedal, delay pedal, pedals that affect the attack and decay of a reproduced note and any other pedal typically used with real guitars.
The tilt sensor of controller 200 may be used as part of a gameplay mechanic. In one specific embodiment, tilting the guitar vertically causes “star power deployment” and is indicated by scoring, graphical, and sonic changes in the game. For example, tilting the guitar vertically changes the excitement of the simulated crowd, the number of points a player receives, the rate at which a player accumulates points, the overall reverberation of the music, the sound quality of the guitar notes, and other graphical and audio effects.
Although described in the context of a rhythm action game, the simulated guitar controller 200 may be used with any genre of game, including first-person shooter, survival horror, action adventure, fighting games, role playing games, real-time strategy games, platformers, puzzle games, racing games, sports games, and stealth action games, third-person shooters. The simulated guitar controller 200 may also be used with rhythm action games that do not center on performance of a musical work using an instrument, such as Dance Dance Revolution of Karoke Revolution, both published by Konami.
Having described certain embodiments of the invention, it will now become apparent to one of skill in the art that other embodiments incorporating the concepts of the invention may be used. Although the described embodiments relate to the field of rhythm-action games, the principles of the invention can extend to other areas that involve musical collaboration or competition by two or more users connected to a network. Therefore, the invention should not be limited to certain embodiments, but rather should be limited only by the spirit and scope of the following claims.
