Description

BACKGROUND

Playing and listening to live music has been captivating humans for millennia. Traditionally, live performances featured little in the way of visual effects. More recently, live performances have been augmented by video, lighting effects, pyrotechnics, and props. While these effects have been entertaining, they do not let the audience experience the musician's point of view. These effects are further limited in that they are not controllable by the musician during the performance.

DETAILED DESCRIPTION

Systems and methods for providing virtual instrument visualization effects corresponding to movement of physical objects, such as drum sticks, a violin bow, a guitar pick, a conductor baton, or the like are described herein. The systems and methods described herein are used to augment and enrich experiences from traditional musical instruments by communicating with a device to perform motion sensing, gesture detection, and wireless communication.
The systems and methods described herein are used for music performance with enhanced experiences. Motion sensing is added to one or more musical instruments, such as a drum stick, a violin/viola/cello bow, a guitar pick, an end of a guitar (e.g., headstock), a conductor's baton, or the like. The musical experience of an artist or audience may be enhanced, and may include real instruments or virtual instruments, such as those used in virtual reality (VR) or augmented reality (AR) systems.
Some traditional systems may use one or more cameras to track musical instruments. An issue with these traditional systems is that they may be occluded by a player's own hand. The presently described systems and methods use a sensor, such as a nine-axis gyroscope and accelerometer, which may measure rotation, location, or orientation. The sensor may be used without a camera, which allows uninterrupted rotation, location, or orientation information to be available while a user plays, without concern for a camera line of sight.
In an example, the systems and methods described herein provide audible and visual feedback to be played and displayed, respectively, when an action, motion, or gesture occurs at a device (e.g., a drum stick, a violin/viola/cello bow, a guitar pick, an end of a guitar, a conductor's baton, or the like). In an example, the audible feedback may include sound created at a musical instrument by the action, motion, or gesture (e.g., when a violin how traverses a violin string, the string vibrates, causing sound to be produced), which may be augmented (e.g., amplified and played by a speaker, changed, or distorted) or the created sound may be added to by the audible feedback (e.g., additional sound may be played not caused by the musical instrument). In another example, the audible feedback may include sound created by a computer system, such as a Musical Instrument Digital Interface (MIDI) system, a drum kit, etc. This type of audible feedback may be created by, for example, tracking a gesture of one or more drum sticks (e.g., without hitting an actual drum), tracking movement of a conductor's baton, etc.
The visual feedback provided in the system may be displayed for an audience, a performer, a remote viewer, or a combination thereof. The visual feedback may include using a display screen, a VR or AR display, etc. Other visual feedback may include fireworks, animated or video sequences, lighting effects on a wearable device, or the like. The visual or audible feedback described herein may be based on additional activity of a user, such as dancing, gestures, predetermined effects, or the like.
FIG. 1 illustrates a pair of drum sticks 100 for creating visualization or audio effects in accordance with some embodiments. The pair of drum sticks 100 include a first drum stick 102A and a second drum stick 10213. Each of the pair of drum sticks 100 includes a respective motion sensor 104A and 104B and respective circuitry 106A and 106B. Although a single sensor 104A and 104B are illustrated in FIG. 1, it is understood that multiple sensors may be used on each drum stick 102A and 102B. The circuitry 106A and 106B may include a transceiver, a processor, memory, or a system on a chip. In an example, the first drum stick 102A may be a parent and the second drum stick 102B may be a child. The parent may receive information from the sensor 104B of the child, and the parent may forward that sensor information along with information from the sensor 104A of the parent to a device, such as a mobile device, a computer, a server, etc., for further processing. In another example, the pair of drum sticks 100 may independently send information to a device.
The pair of drum sticks 100 may be paired by assigning one to a left hand of a user and one to a right hand of a user (or simulating such). The left hand assigned drum stick may be assigned to output a first set of audible or visual feedback and the right hand assigned drum stick may be assigned to output a second set of audible or visual feedback. For example, either drum stick may be used to cause drum sound as audible feedback based on the location and motion of the drum stick, and one of the drum sticks may be assigned to a first visual effect (e.g., a flashing light on a proximate wearable device), and the other of the drum sticks may be assigned to a second visual effect (e.g., a visual effect on a display screen).
The sensors 104A, 104B may include a magnetometer, accelerometer, or gyroscope, For example, the sensors 104A, 104B may include a nine-axis sensor with a magnetometer, accelerometer, and a gyroscope for detecting location, position, and movement. The sensors 104A, 104B may be initiated at a starting location, position, or orientation, such that the sensors 104A, 104B may determine relative locations, positions, movement, or orientations in response to changes by the pair of drum sticks 100.
The sensor 104A may provide data based on movement of the drum stick 102A. The transceiver of circuitry 106A may transmit the sensor data to a device, such as a wearable device (e.g., a smart watch), a mobile device, a computer, a remote server, or the like. The device receiving the sensor data may include a processor to recognize a gesture from the sensor data. The gesture may be used to determine a visualization effect corresponding to the gesture or an audio effect including a drum sound corresponding to the gesture. The gesture may include movement from the pair of drum sticks 100 in coordination with each other. In an example, timing information may be sent to coordinate displaying the visualization effect and playing the audio effect. The gesture may be based on an orientation, location, movement, or force of one or both of the pair of drum sticks 100, for example as determined by one or more of the first sensor 104A or the second sensor 104B.
The gesture may be determined based on additional input, such as an additional sensor attached to an ankle or a foot of a user controlling the drum stick 102A. The additional sensor may output data to cause a second audio effect, such as a second drum sound (e.g., a bass drum sound) corresponding to a second gesture. The second audio effect may be played by a speaker. The gesture may include one or more of a linear movement, a tapping movement, a sweeping movement, a minimum acceleration, a minimum deceleration, or the like.
A display device may be used to display the visualization effect or a speaker may be used to play the audio effect. The speaker may be controlled by a MIDI player. The audio effect may include Multidimensional Polyphonic Expression instructions for use by the MIDI player. In an example, the processor of circuitry 106A may be used to determine the gesture. In an example, a visualization effect may be determined based on one or more previously recognized gestures (e.g., a series). The visualization effect may include using a plurality of wearable devices within a predetermined proximity of the drum stick 102A to display the visualization effect. Devices within the predetermined proximity may include devices on a network, within range of a Bluetooth device or devices, within a specified distance, within a room, etc.
FIGS. 2A-2C illustrate example visualization effects 200A-200C in accordance with some embodiments. The first visualization effect 200A includes sensor visualization effects 202 and orientation visualization effects 204 and 206. The second visualization effect 200B includes a front-facing view of a drum set and a drummer. The third visualization effect 200C includes a point-of-view perspective display of a drum set 208. The components of the visualization effects 200A-200C may include virtual components or augmented reality components. For example, the drum sets displayed in visualization effects 200B-200C may be virtual (e.g., displayed using a VR display).
Motion data or gesture primitives detected by a sensor may be used to create visualizations or visual effects to accompany a performance, such as to enhance an audience experience. For example, enhanced visual experiences may be shown, such as capturing activity level (e.g., sensor visualization effects 202 related to an accelerometer or gyroscope of a drum stick or other musical instrument), orientation of the musical instrument device (e.g., drum sticks, as shown in the orientation visualization effects 204-206), or other aspects of a performance. A system to predetermine the visualization effect 200A may include a customizable platform to select a background or visual effects, which may be manipulated by a user. Audience interaction may be enabled, such as at wearable devices (e.g., wrist bands) where lights may turn on and off, which may be controlled using the musical instrument device (e.g., drum sticks).
In an example, the visualization effects 200A-200B may be presented to an audience of a user controlling a musical instrument device. For example, a display screen may be used to display visualization effects 200A or 200B. For visualization effect 200C, the point-of-view drum set 208 may be presented, in an example, on a display screen to an audience. In an example, the visualization effect 200C may be presented using a VR display to a controller of the musical instrument device (e.g., drum sticks). The visualization effect 200C within the VR display may show the point-of-view drum set 208 and may include virtual drum sticks 210 or a virtual pedal 212. The virtual drum sticks 210 may be displayed virtually at a location corresponding to real drum sticks based on sensors and location information of the real drum sticks. The user of the real drum sticks, while wearing the VR display, may see the virtual drum sticks 210 as if the user was holding the virtual drum sticks 210 (and hands may also be shown to further this effect). The user may wear an ankle or foot device with a sensor to detect motion of the ankle or foot. The detected motion may cause the foot pedal 212 to move (e.g., in the VR environment) and may cause an audible or visual effect to occur. The user wearing the VR display may play the drum set 208 virtually with the virtual drum sticks 210 by controlling the real drum sticks (and optionally the foot pedal 212). The drum set 208 may move or display a visualization according to motion of the real drum sticks (e.g., the cymbals may crash, a drum head may appear to vibrate, a played drum may light up, etc.).
FIGS. 3A-3C illustrate instrumentation objects 300A-300C for creating visualization or audio effects in accordance with some embodiments.
For example, the instrumentation object 300A may be a violin bow, viola bow, cello bow, or other stringed instrument bow. The instrumentation object 300A includes a sensor 304 and may include circuitry 306, such as a transceiver, a processor, memory, or a system on a chip. In the example shown in FIG. 3A, the sensor 304 is located at the tip of the instrumentation object 300A. In other examples, the sensor 304 may be located in the middle of the instrumentation object 300A or at the frog. The sensor 304 may include a gyroscope, an accelerometer, or a magnetometer to determine position, orientation, or movement of the instrumentation object 300A. In an example, a plurality of sensors may be disposed on the instrumentation object 300A (e.g., one at the tip, one in the middle, and one at the frog).
The sensor 304 may track back and forth movement of the instrumentation object 300A. The sensor 304 may track bow tapping movements (e.g. in a perpendicular or partially perpendicular movement to the back and forth traditional bow movement on a stringed instrument). The tracked movement (or position or orientation) of the instrumentation object 300A may be used to create or identify visual effects to be shown. The visual effects may be matched to the music created by playing the stringed instrument with the instrumentation object 300A. In another example, augmented audible feedback may be created or identified by the tracked movement, which may be played in addition to the music created. For example, a real violin may be played using the instrumentation object 300A as a bow, and the sensor on the bow may add to a performance experience by integrating visual or audio effects in addition to the music created by playing the violin. For example, when the bow moves in a first direction, a first visual or audible effect may be created or identified and when the bow moves in a second direction, a second visual or audible, effect may be created or identified. In an example, mixers may be used to add in augmented sound. For example, a Multidimensional Polyphonic Expression for use with a MIDI player may be used to create or play the augmented sound.
In an example, a player of an instrument using the instrumentation object 300A may have a sensor on a finger or fingers of the player. For example, a violin player may place a sensor or sensors on one or more fingers used to play violin (e.g., a fourth finger of the player's left hand). The movement of the pinky finger may indicate a particular visual effect. For example, when playing a stringed instrument, notes may often be played interchangeably with different fingers (e.g., the fourth finger in first position on a first string, an open second string, or a second finger in a third position on the first string may all correspond to a single note). By playing with a particular finger, a specific visual (or audible) affect may be identified or created.
The instrumentation object 300A may be in communication with a server. The server may include a processor to receive sensor data from the sensor 304 of the instrumentation object 300A, the sensor data may be based on movement of the instrumentation object 300A. The processor may recognize a gesture from the sensor data, such as a back or forth movement, a tapping of the instrumentation object 300A on a string, etc. The processor may determine, such as from the gesture, a visualization effect corresponding to the gesture or an audio effect corresponding to the gesture. The visualization effect may be determined using a visualization engine. In an example, the processor may cause the visualization effect or the audio effect to be output in response to the determination. The audio effect may include a natural sound caused by the movement of the instrumentation object 300A.
In an example, causing the visualization effect to be output may include sending the visualization effect to a virtual reality headset of a user controlling the instrumentation object 300A, for example, to be displayed on the VR headset. Causing the audio effect to be output may include sending the audio effect to a speaker to play the audio effect. The processor may send the visualization effect to a display to be displayed in coordination with the audio effect played by the speaker. The processor may receive data from the sensor 304 indicating an initial position of the instrumentation object 300A and recognize the gesture based on a determined final position of the instrumentation object 300A. The visualization effect or the audio effect may be determined based on an orientation of the instrumentation object 300A identified in the sensor data. The visualization effect may be based on one or more (e.g., a series) of previously recognized gestures. The visualization effect may include a lighting effect. Outputting the visualization effect may include sending the lighting effect to a plurality of wearable devices, such as within a predetermined proximity of the instrumentation object 300A to be displayed, for example at the plurality of wearable devices. Devices within the predetermined proximity may include devices on a wi-fi network, within range of a Bluetooth device or devices, within a specified distance, within a room, etc. The gesture may include a linear movement, a tapping movement, a sweeping movement, a minimum or maximum acceleration, a maximum or minimum deceleration, or the like. The audio effect may include a Multidimensional Polyphonic Expression instruction for a MIDI player.
The instrumentation object 300B may be a guitar pick. The instrumentation object 300B includes a sensor 310 and may include circuitry 312, such as a transceiver, a processor, memory, or a system on a chip. The instrumentation object 300B may be used to strum a stringed instrument, such as a guitar. Movement of the instrumentation object 300B may correspond with a visual or audible effect to be produced. For example, when the instrumentation object 30013 is used to strum a guitar upward, a first visual or audible effect may be identified and when the instrumentation object 3009 is used to strum the guitar downward, a second visual or audible effect may be identified and used.
The instrumentation object 3009 may be in communication with a server. The server may include a processor to receive sensor data from the sensor 310 of the instrumentation object 300B, the sensor data may be based on movement of the instrumentation object 300B. The processor (e.g., circuitry 312) may recognize a gesture from the sensor data, such as a strumming movement, a slapping movement, etc. The processor may determine, such as from the gesture, a visualization effect corresponding to the gesture or an audio effect corresponding to the gesture. The visualization effect may be determined using a visualization engine. In an example, the processor may cause the visualization effect or the audio effect to be output in response to the determination. The audio effect may include a natural sound caused by the movement of the instrumentation object 300B.
In an example, causing the visualization effect to be output may include sending the visualization effect to a virtual reality headset of a user controlling the instrumentation object 300B, for example, to be displayed on the VR headset. Causing the audio effect to be output may include sending the audio effect to a speaker to play the audio effect. The processor may send the visualization effect to a display to be displayed in coordination with the audio effect played by the speaker. The processor may receive data from the sensor 310 indicating an initial position of the instrumentation object 3009 and recognize the gesture based on a determined final position of the instrumentation object 300B. The visualization effect or the audio effect may be determined based on an orientation of the instrumentation object 300B identified in the sensor data. The visualization effect may be based on one or more (e.g., a series) of previously recognized gestures. The visualization effect may include a lighting effect. Outputting the visualization effect may include sending the lighting effect to a plurality of wearable devices, such as within a predetermined proximity of the instrumentation object 300B to be displayed, for example at the plurality of wearable devices. Devices within the predetermined proximity may include devices on a wi-fi network, within range of a Bluetooth device or devices, within a specified distance, within a room, etc. The gesture may include a linear movement, a tapping movement, a sweeping movement, a minimum or maximum acceleration, a maximum or minimum deceleration, or the like. The audio effect may include a Multidimensional Polyphonic Expression instruction for a MIDI player.
The instrumentation object 300C may be a conductor's baton. The instrumentation object 300C includes a sensor 316 and may include circuitry 318, such as a transceiver, a processor, memory, or a system on a chip. The instrumentation object 300C may be used to conduct an orchestra, either real or virtual. The real orchestra may play music in response to movement of the instrumentation object 300C or orchestral sound may be created in response to movement of the instrumentation object 300C with a virtual orchestra. A visual effect or audible effect may be created or identified in response to movement of the instrumentation object 300C.
The instrumentation object 300C may be in communication with a server. The server may include a processor to receive sensor data from the sensor 316 of the instrumentation object 300C, the sensor data may be based on movement of the instrumentation object 300C. The processor (e.g., circuitry 318) may recognize a gesture from the sensor data, such as a up and down or left and right movement, a conducting cadence movement (e.g., based on a tempo of music being played, such as 3/4, 4/4, 7/8, etc.), or the like. The processor may determine, such as from the gesture, a visualization effect corresponding to the gesture or an audio effect corresponding to the gesture. The visualization effect may be determined using a visualization engine. In an example, the processor may cause the visualization effect or the audio effect to be output in response to the determination.
In an example, causing the visualization effect to be output may include sending the visualization effect to a virtual reality headset of a user controlling the instrumentation object 300C, for example, to be displayed on the VR headset. Causing the audio effect to be output may include sending the audio effect to a speaker to play the audio effect. The processor may send the visualization effect to a display to be displayed in coordination with the audio effect played by the speaker. The processor may receive data from the sensor 316 indicating an initial position of the instrumentation object 300C and recognize the gesture based on a determined final position of the instrumentation object 300C. The visualization effect or the audio effect may be determined based on an orientation of the instrumentation object 300C identified in the sensor data. The visualization effect may be based on one or more (e.g., a series) of previously recognized gestures. The visualization effect may include a lighting effect. Outputting the visualization effect may include sending the lighting effect to a plurality of wearable devices, such as within a predetermined proximity of the instrumentation object 3000 to be displayed, for example at the plurality of wearable devices. Devices within the predetermined proximity may include devices on a wi-fi network, within range of a Bluetooth device or devices, within a specified distance, within a room, etc. The gesture may include a linear movement, a tapping movement, a sweeping movement, a minimum or maximum acceleration, a maximum or minimum deceleration, or the like. The audio effect may include a Multidimensional Polyphonic Expression instruction for a MIDI player.
FIG. 4 illustrates a system 400 for providing effects corresponding to movement of an instrumentation object in accordance with some embodiments. Remote instrumentation devices may include a drum stick 410, a violin bow 416, a guitar pick 422, a conductor's baton 428, or the like. The instrumentation devices 410, 416, 422, and 428 may include respective sensors (e.g., 412, 418, 424, 430) and optionally respective transceivers or processors (e.g., 414, 420, 426, 432).
The system 400 includes a server 401 in communication with one or more remote instrumentation devices (e.g., 410, 416, 422, 428), or a wearable device 408. The server 401 includes a processor 402, memory 404, and a visualization engine 406. The processor 402 may receive sensor data from a sensor (412, 418, 424, or 430) of one or more of the remote instrumentation devices (e.g., 410, 416, 422, 428), such as the drum stick sensor 412. The drum stick 410 may be paired with a second drum stick, and the pair may include a parent and a child drum stick. For example, the child drum stick may have limited communication capabilities (e.g., capable of communicating with the parent drum stick, but may be incapable of communicating with another remote device. The parent drum stick may have the processor 414 or a transceiver, for example to communicate with a mobile device, wearable device, or remote device. The pair of drum sticks may be used together. The processor 402 may receive the sensor data from one of the pair of drum sticks (e.g., a parent) or both (e.g., individually, or via the parent). In an example, the sensor data is based on movement of the drum stick 410.
In an example, the processor 402 may recognize a gesture from the sensor data. For example, the gesture may include a drum strike, a violin playing movement, a conductor baton conducting movement, a guitar strum, etc. The gesture may include one or more of a linear movement, a tapping movement, a sweeping movement, a minimum or maximum acceleration, a minimum or maximum deceleration, or the like. The processor 402 may determine, for example using the gesture, a visualization effect corresponding to the gesture. The visualization effect may be determined using the visualization engine 406. In an example, to determine the visualization effect, the processor 402 is to determine the visualization effect based on a series of previously recognized gestures. The visualization effect may include a lighting effect, such as a flashing light or light sequence on a screen, a virtual reality light effect, or a light effect sent for display to a plurality of wearable devices (e.g., the wearable device 408). The plurality of wearable devices may be identified within a proximity of the remote instrumentation devices (e.g., 410, 416, 422, 428). The processor 402 may receive wearable sensor data from the plurality of wearable devices (e.g., the wearable device 408), which may be within a predetermined proximity of the remote instrumentation devices (e.g., 410, 416, 422, 428). The visualization effect may be modified, for example, based on the wearable sensor data. Devices within the predetermined proximity may include devices on a wi-fi network, within range of a Bluetooth device or devices, within a specified distance, within a room, etc.
The processor 402 may determine an audio effect corresponding to the gesture including, for example, a drum sound, a violin sound (or other stringed instrument sound), a guitar sound, an orchestral sound (e.g., a combination of sounds from a plurality of instruments), or the like. In an example, the visualization effect and the audio effect are determined based on an orientation of the remote instrumentation devices (e.g., 410, 416, 422, 428) identified in the sensor data. In an example, the audio effect may include Multidimensional Polyphonic Expression instructions for a musical instrument digital interface (MIDI) player.
The processor 402 may cause the visualization effect or the audio effect to be output, such as in response to the determination. In an example, the visualization effect may be output to a virtual reality headset 434, which may display the visualization effect using a virtual reality display. The virtual reality headset 434 may be on a user who is controlling a remote instrumentation device (e.g., 410, 416, 422, 428). The visualization effect may be displayed in coordination with the audio effect played, for example, by a speaker. The speaker may be used to play the audio effect.
In an example, the processor 402 may receive data from the sensor indicating an initial position of the remote instrumentation devices (e.g., 410, 416, 422, 428). For example, the processor 402 may determine a final position of the remote instrumentation devices (e.g., 410, 416, 422, 428), such as a drum stick 410. In an example, the drum stick 410 may be used to generate the drum sound (e.g., without striking a drum), which may be determined based on the initial position and the final position.
In an example, the processor 402 may receive additional sensor data from a second sensor attached to an ankle or a foot of a user who is controlling the drum stick. A second gesture may be recognized from the additional sensor data. The processor 402 may determine from the second gesture, a second audio effect or a second visualization effect. The second audio effect may include a second drum sound corresponding to the second gesture. The processor 402 may cause the second audio effect or the second visualization effect to be output with the visualization effect or the audio effect.

The technique 500 includes an operation 506 to determine a visualization effect and an audio effect. The effects corresponding to the gesture. In an example, determining the visualization effect includes using a visualization engine. In an example, determining the visualization effect includes determining the visualization effect based on one or more (e.g., a series) of previously recognized gestures. The audio effect may include Multidimensional Polyphonic Expression instructions for a MIDI player.
The technique 500 includes an operation 508 to output the visualization effect and the audio effect, such as in response to the determination. Outputting the visualization effect may include sending the visualization effect to a virtual reality headset of a user controlling the pair of drum sticks to be displayed on the virtual reality headset. Outputting the audio effect may include sending the audio effect to a speaker to play the audio effect. The visualization effect and the audio effect may be displayed and played, respectively, in coordination.
In an example, the technique 500 may include receiving data from the sensor indicating an initial position of the drum stick, and recognizing the gesture may include determining a final position of the drum stick. The drum sound may be determined based on the initial position or the final position. The visualization effect corresponding to the gesture or the audio effect including the drum sound may corresponding to the gesture may be determined based on an orientation of the drum stick identified in the sensor data.
The technique 500 may include receiving additional sensor data from a second sensor attached to an ankle or a foot of a user controlling the drum stick, recognizing a second gesture from the additional sensor data, determining, from the second gesture, a second audio effect including a second drum sound corresponding to the second gesture, and causing the second audio effect to be output with the visualization effect and the audio effect. The technique 500 may include receiving wearable sensor data from a plurality of wearable devices, such as within a predetermined proximity of the drum stick. The visualization effect may be modified based on the wearable sensor data. The visualization effect may include a lighting effect, which may be sent to a plurality of wearable devices within a predetermined proximity of the drum stick, such as to be displayed at the plurality of wearable devices. Devices within the predetermined proximity may include devices on a wi-fi network, within range of a Bluetooth device or devices, within a specified distance, within a room, etc.
FIG. 6 illustrates generally an example of a block diagram of a machine 600 upon which any one or more of the techniques (e.g., methodologies) discussed herein may perform in accordance with some embodiments. In alternative embodiments, the machine 600 may operate as a standalone device or may be connected (e.g., networked) to other machines. In a networked deployment, the machine 600 may operate in the capacity of a server machine, a client machine, or both in server-client network environments. In an example, the machine 600 may act as a peer machine in peer-to-peer (P2P) (or other distributed) network environment.
