TECHNICAL FIELD
The present invention relates generally to the field of musical apparatus. More specifically, the present invention relates to a musical performance and composition apparatus incorporating a user interface that is adaptable for use by individuals with physical disabilities. Similarly, the present invention relates to a wireless electronic musical instrument, enabling musicians of all abilities to learn, perform, and create sound.
BACKGROUND OF THE INVENTION
For many years as is common today, performing music is restricted to traditional instruments such as acoustic and electronic keyboards, stringed, woodwind, percussive and brass. In all of the instruments in each of these classifications, a high level of mental aptitude and motor skill is required to adequately operate the instrument. Coordination is necessary to control breathing, fingering combinations, and expression. Moreover, the cognitive ability to read the music, watch the conductor for cues, and listen to the other musicians to make adjustments necessary for ensemble play require high cognitive function. Most school band programs are limited to the use of these instruments and limit band participation to only those students with the physical and mental capacity to operate traditional instruments.
For example, a student with normal mental and physical aptitude shows an interest in a particular traditional instrument, and the school and/or parents make an instrument available with options for instruction. The child practices and attends regular band rehearsals. Over time, the student becomes proficient at the instrument and playing with other musicians. This is a very common scenario for the average music student.
However, this program assumes all children have adequate cognitive and motor function to proficiently operate a traditional instrument. It assumes that all children are capable of reading music, performing complex fingering, controlling dynamics, and making necessary adjustments for ensemble performance. The currently available musical instruments do not consider individuals with below normal physical and mental abilities. Hence, it prohibits the participation of these individuals.
Teaching music performance and composition to individuals with physical and mental disabilities requires special adaptive equipment. Currently, these individuals have limited opportunities to learn to perform and compose their own music because of the unavailability of musical equipment that is adaptable for their use. Teaching music composition and performance to individuals with physical and mental disabilities requires instruments and teaching tools that are designed to compensate for disabled students' limited physical and cognitive abilities.
For example, students with physical and mental disabilities such as cerebral palsy often have extremely limited manual dexterity and thus are unable to play the typical keyboard instrument with a relatively large number of narrow keys. Similarly, a user with physical disabilities may have great difficulty grasping and manipulating drumsticks and thus would be unable to play the typical percussion device. Also, disabled users are unable to accurately control the movements of their hands, which, combined with an extremely limited range of motion, can also substantially limit their ability to play keyboard, percussion, or other instruments. Such users may, however, exhibit greater motor control using their head or legs.
Furthermore, the currently available musical instruments are generally inflexible in regard to the configurations of their user interfaces. For example, keyboards typically have a fixed number that cannot be modified to adapt to the varying physical capabilities of different users. In addition, individuals with cognitive delays are easily distracted and can lose focus when presented with an overwhelming number of keys. Similarly, teaching individuals with mental and physical disabilities basic music theory requires a music tutorial device that has sufficient flexibility to adjust for a range of different cognitive abilities.
Consequently, there is a need in the art for a music performance and composition apparatus with a user interface adaptable for use by individuals with physical and mental disabilities, such that these individuals can perform and compose music with minimal involvement by others. In addition, there is a need for an apparatus allowing disabled users to use the greater motor control available in their head or legs. Furthermore, there is a need in the art for a music composition and performance tutorial system incorporating this new apparatus that allows musicians with disabilities to learn to compose and perform their own music.
Similarly, there is a need in the art for a universal adaptive musical instrument that enables people of all abilities to perform music alone, with other individuals of similar abilities, or with others in a traditional band setting. This solution could provide the necessary flexibility to assist individuals with their particular disability.

DETAILED DESCRIPTION
FIG. 1 shows a schematic diagram a music apparatus 10, according to one embodiment of the present invention. As shown in FIG. 1, the music apparatus 10 may include a user console 20 having at least one actuator 30 with an actuator button 31, a voltage converter 100, a processing computer 150 having a processor 154, software 152, and an internal sound card 148, a display monitor 180, and a speaker 159. In a further embodiment, the voltage converter 100 is an integral component of the user console 20. The actuator 30 is connected to the voltage converter 100 with an actuator cable 35. The voltage converter is connected to the processing computer 150 with a serial cable 145. The processing computer 150 is connected to the display monitor 180 by a monitor cable 177. The processing computer 150 is connected to the speaker 159 by a speaker line out cable 161.
In an alternative aspect of the present invention, the apparatus also has an external MIDI sound card 155 and a MIDI sound module 170. According to this embodiment, the processing computer 150 is connected to the external MIDI sound card 155 by a USB cable 156. The MIDI sound card 155 is connected to the MIDI sound module 170 via a MIDI cable 42. The MIDI sound module 170 is connected to the internal sound card 148 via an audio cable 158.
In a further alternative embodiment, the apparatus has a lighting controller 160 controlling a set of lights 162. The lighting controller 160 is connected to the processing computer 150. The lighting controller 160 is also connected to each light of the set of lights 162. The lighting controller 160 can be any known apparatus for controlling a light or lighting systems. The set of lights 162 can be one light. Alternatively, the set of lights 162 can be comprised of any number of lights.
In one embodiment, the actuator 30 may be any known mechanical contact switch that is easy for a user with disabilities to operate. Alternatively, different types of actuators, for example, light sensors, may also be used. In one aspect of the present invention, the number of actuators 30 can vary according to factors such as the user's skill level and physical capabilities. While FIG. 1 shows an embodiment having a single actuator 30 on the user console 20, further embodiments may have a plurality of actuators 30.
According to one embodiment, the processing computer 150 may be any standard computer, including a personal computer running a standard Windows® based operating system, with standard attachments and components (e.g., a CPU, hard drive, disk and CD-ROM drives, a keyboard and a mouse). The processor 154 may be any standard processor such as a Pentium® processor or equivalent.
FIG. 1A depicts a schematic diagram of a music apparatus 11, according to an alternative embodiment of the present invention. The apparatus 11 has a user console 20 with eight actuators 30 and a wireless transmitter 19, a converter 100 with a wireless receiver 17, and a processing computer 150. The actuators 30 are connected to the wireless transmitter 19 with actuator cables 31. In place of the electrical connection between the actuator 30 and the voltage converter 100 according to the embodiment depicted in FIG. 1, the wireless transmitter 19 shown in FIG. 1A can transmit wireless signals, which the wireless receiver 17 can receive.
FIG. 2 is a flow diagram showing the operation of the apparatus 10, according to one embodiment of the present invention. The user initiates operation by pressing the actuator button 31 (block 60). Upon engagement by the user, the actuator 30 transmits an actuator output signal to a voltage converter 100 through the actuator cable 35 (block 62). Alternatively, the actuator 30 transmits the output signal to the wireless transmitter 19, which transmits the wireless signal to the wireless receiver 17 at the voltage converter. The voltage converter 100 receives the actuator output signal 36 and converts the actuator output signal 36 to a voltage converter output signal 146 (block 64). The voltage converter output signal 146 is in the form of a serial data stream which is transmitted to the processing computer 150 through a serial cable 145 (block 66). At the processing computer 150, the serial data stream is processed by the software 152 and transmitted as an output signal to the speaker 159 to create sound (block 68). In accordance with one aspect of the invention, the serial data contains further information that is further processed and additional appropriate action is performed (block 70). That is, the additional action message information contained in the data stream is read by the software 152, which then initiates additional action. According to one embodiment, the additional information is merely repeated actuator address and actuator state information based on repeated actuations of the actuator 30 by the user. The software 152 defines and maps one or more actions to be executed by the hardware and/or software upon receiving the information. For purposes of this application, the information received by the hardware and/or software will be referred to as an output signal. According to one embodiment, the information is a command.
According to one embodiment, the step of processing the serial data stream, converting it into an output signal, and transmitting the signal to a speaker 159 to create sound (block 68) involves the use of a known communication standard called a musical instrument digital interface (“MIDI”). According to one embodiment, the software 152 contains a library of preset MIDI commands and maps serial data received from the voltage converter output signal 146 to one or more of the preset commands. As is understood in the art, each MIDI command is sent to the MIDI driver (not shown) of the processing computer 150. The MIDI driver directs the sound to the internal sound card 148 for output to the speaker 159.
Alternatively, the MIDI command is transmitted by the MIDI sound card from the processing computer 150 to the MIDI sound module 170. The MIDI sound module may be any commercially-available MIDI sound module containing a library of audio tones. The MIDI sound module 170 generates a MIDI sound output signal which is transmitted to the processing computer 150. A signal is then transmitted to the speaker 159 to create the predetermined sound.
FIG. 1B shows a schematic diagram a music apparatus according to one embodiment of the present invention. As shown in FIG. 1B, the music apparatus may include optional external speakers 201, an external wireless transmitter 204, and external MIDI sound generator 212, a processing computer 213 having a processor 203, software 239, an internal/external sound card 202, and a display monitor 205. The processing computer 213 is connected to the display monitor 205 by a monitor cable 206. The processing computer 213 is connected to the speaker 201 by a speaker line out cable 207. The wireless transmitter 204 is connected to the processing computer 213 via a cable 208. Likewise, the optional external MIDI device 212 is connected to the processing computer 213 via a MIDI cable 238. A remote wireless device 211 contains a processor, touch-sensitive LCD display 244, and software 240. In an alternative embodiment of this remote wireless device 211, a serial connector 242, serial cable 209, and actuator switch 210 are optional.
FIG. 1C presents an alternative aspect of the present invention. The processing computer 213 contains a touch-sensitive LCD 205, thus eliminating the monitor display cable 6.
FIG. 1D presents yet another embodiment of the present disclosure. In addition to, or in place of touch sensitive LCD 244, the remote wireless device 311 can contain an accelerometer 344 or any other position sensitive device that can determine position and/or movement such as two dimensional or three dimensional position or movement, and generate data indicating the position and/or movement of the remote wireless device 311. In order to determine position, in one embodiment, the wireless device 311 can be initialized by establishing a point of reference that can be the position of the remote wireless device at some initial time. Subsequent movements are tracked and thus a position can be maintained.
The remote wireless device 311 can contain additional software 340 that can be capable of reading the accelerometer data and sending that data to the processing computer 213. Either software 239 or 340 can translate the accelerometer data into a coordinate in a two-dimensional or three-dimensional coordinate space. The software 239 or 340 can define multiple regions in this space. These regions can relate to, for example the three dimensional space surrounding the performer and can include all or some of the space behind, in front of, to the left or right, and above and below a performer. The sizing, positioning, and number of regions can be related to the physical ability of the performer, as determined by the performer, the processing host computer 213, or by another individual. The processing host computer 213 can then trigger music, lighting, or display events based on the position and/or motion of the remote wireless device 311 in the defined two, or three-dimensional mapping. Different events can be generated based on the region the remote wireless device is in, or was moved to, or based on the motion carried out in that region. For example, when the remote wireless device 311 is moved within one region, processing host computer 213 can trigger a particular sound to be played through external speaker 201. Movement into, or in a different region may produce a different sound, or even a different type of event.
In another embodiment, the type of motion may trigger a specific type of event. For example, a drumming motion may cause processing host computer 213 to play a drum sound through external speaker 201, while a strumming motion may produce a guitar sound. Some embodiments can play certain sounds in certain regions based on the type of motion and generate completely different events in response to the same type of motions in a different region.
Another embodiment may measure the speed of the motion to trigger events. This motion may for example, change the tempo of the events generated by the processing host computer 213, change the events triggered, and/or change the volume or pitch of the sound produced, and/or otherwise change the character of the event.
If a touch sensitive LCD 244 is included with the accelerometer, the LCD can be used as previously described, giving the performer the option of which method of playing to use. The LCD can also be used to display cues to the performer to produce motion or move to a certain region. The LCD can also be used with the motion. For example, a performer could press an area of the screen simultaneously with the motion. The function of the LCD screen can vary depending on the abilities of the user. For example, more sophisticated performers capable of more coordinated body motions can use the LCD screen and motion at the same time, whereas less coordinated performers can use one or the other depending on their desires and physical abilities. Alternatively, performers can be either cued to press the LCD screen or to move the remote wireless device. For example, one cue might direct the performer to move the wireless device and the next cue might be to touch a specific point on the LCD display. Such alternation can be in a predetermined pattern or frequency based on the abilities of the user, or may be random, or may be predetermined in advance. If an LCD display is not provided, the user can still be presented with cues through monitor 205, LCD monitor 205 or through other audio and/or visual cues including lighting cues, sound cues, or cues may not be provided at all.
The use of an accelerometer is not limited to the embodiment as described in FIG. 1D and may supplement any of the embodiments listed herein.
FIG. 1E presents a further alternative embodiment of the present disclosure. In addition to, or in place of touch sensitive LCD 244 and/or accelerometer 344, remote wireless device 411 can contain a proximeter 444, and additional software 440. The proximeter is capable of measuring distances between the wireless device and objects near the device and translate that into position and movement coordinates such as two dimensional or three dimensional position or movement coordinates. In order to determine position, in one embodiment, the wireless device 411 can be initialized by establishing a point of reference that can be the position of the wireless device at some initial time. Subsequent movements of the wireless device or changes in proximity of objects around the wireless device are tracked and thus a position can be maintained.
These position and movement coordinates are then sent to processing host computer 213. The proximiter can be in the remote wireless device 411, or attached to the remote wireless device 411 as an accessory. The proximeter 444 can detect distances between the proximeter and the remote wireless device 411 and/or nearby objects. The proximeter can be inductive, capacitive, capacitive displacement, eddy-current, magnetic, photocell (reflective), laser, sonar, radar, doppler based, passive thermal infrared, passive optical, or any other suitable device. The proximeter 444 can be stand alone, that is, exist solely in the wireless device 411 measuring distances, or can work in co-operation with an element on the measured object or surface to produce a measurement.
The software 440 can read the data from the proximiter and can forward that data to the software 239, or can process the data itself to determine a distance from an object. In one embodiment, the proximeter data can be translated by either software 239 or 440 into a coordinate in a two-dimensional or a three dimensional coordinate space. The software 239 or 440 can define multiple regions in this space. These regions can relate to, for example, the three dimensional space surrounding the performer or the measured surface and can include all or some of the space behind, in front of, to the left or right, and above and below a performer or measured surface. The sizing, positioning, and number of regions can be related to the physical ability of the performer, as determined by the performer, the processing host computer 213, or by another individual. This data can then be used by the processing host computer 213 to trigger music, lighting, or display events based on a defined distance-to-event mapping, position, and/or motion of the remote wireless device 411 in the defined two or three-dimensional mapping. Different events can be generated based on the region the remote wireless device is in, or was moved to, or based on the motion carried out in that region. For example, when the remote wireless device 411 is moved within one region, processing host computer 213 triggers an event in the form of a particular sound to play through external speaker 201. Motion or presence of wireless device 411 into or in a different region may produce a different sound, or even a different type of event.
In another embodiment, the type of motion may trigger a specific type of event. For example, a drumming motion may trigger processing host computer 213 to cause a drum sound to be played through external speaker 201, while a strumming motion may produce a guitar sound. Some embodiments can play certain sounds in certain regions based on the type of motion and generate completely different events in response to the same type of motions in a different region.
Another embodiment may measure the speed of the motion to trigger events. This motion, for example, may change the tempo of the events generated by the processing host computer 213, change the events triggered, and/or change the volume and/or pitch of the sound produced.
If a touch sensitive LCD 244 is included with the proximeter, the LCD can be used as described previously, giving the performer the option of which method of playing to use. The LCD can also be used to display cues to the performer to produce motion to vary distances between objects, thereby triggering an event. The LCD can also be used with the motion, for example, a performer could press an area of the screen simultaneously with the motion. The function of the LCD screen can vary depending on the abilities of the user. For example, more sophisticated performers capable of more coordinated body motions can use the LCD screen and motion at the same time, whereas less coordinated performers can use one or the other depending on their desires and physical abilities. Alternatively, performers can be either cued to press the LCD screen or to move the remote wireless device. For example, one cue might direct the performer to move the wireless device and the next cue might be to touch a specific point on the LCD display. Such alternation can be in a predetermined pattern or frequency based on the abilities of the user, may be random, or may be predetermined in advance. If an LCD display is not provided, the user can still be presented with cues through monitor 205, LCD monitor 205, or through other audio and/or visual cues including lighting cues, sound cues, or cues may not be provided at all.
The use of an proximeter is not limited to the embodiment as described in FIG. 1E and may supplement any of the embodiments listed herein.
In one embodiment, as stated above, the actuator 210 may be any known mechanical contact switch that is easy for a user to operate. Alternatively, different types of actuators, for example, light sensors, may also be used. In one aspect of the present invention, the number of actuators 10 can vary according to factors such as the user's skill, physical capabilities and actuator implementation.
According to one embodiment, as stated above, the processing computer 213 may be any standard computer, including a personal computer running a standard Windows® based operating system, with standard attachments and components (e.g., a CPU, hard drive, disk and CD-ROM drives, a keyboard and a mouse). The processor 203 may be any standard processor such as a Pentium® processor or equivalent.
FIG. 6 depicts a sequence diagram of standard operational flow for one embodiment of the present disclosure. The remote wireless device 211 is switched on. The remote wireless device software 240 is started and establishes a wireless connection 243 with the host processing PC 213 via the wireless transmitter (router) 204. Upon successful connection, the remote wireless device transmits a user log on or handshake message 217 to the host PC 213. The host PC 213 returns an acknowledgement message 219. Upon successful log on, the remote wireless device 211 notifies the host PC 213 of it's current device profile 220. The device profile 220 contains data necessary for the host PC 213 to properly service future commands 223 received from the remote device 211. Specifically, during host PC synchronization, a map of host PC 213 actions that correspond to specific remote device 211 x-y coordinates locations (or regions of x-y coordinates) on the remote device 211 LCD display 244 are created. With the mapping complete, both the host PC 213 and remote wireless device 211 are now synchronized. After successful synchronization, the host PC 213 and the remote wireless device 211 refresh their displays 205, 244 respectively. The user may press the LCD display 244 to send a command 223 to the host PC 213. A remote device command 223 transmitted to the host PC 213 contains an identifier to the location the user pressed on the remote device LCD 244. A remote device command 223 may optionally include meta data such as position change or pressure intensity. When the command 23 is received by the host PC 213, the host PC 213 invokes the command processor 224 which executes the action mapped to the location identifier. This action, handled in the command processor 224 may include directing a MIDI command or series of commands to the host PC 213 MIDI output, sending a MIDI command or series of commands to an external MIDI sound generator 212, playing a media file, or instructing the host PC 213 to change a configuration setting. It may also include a script that combines several disparate functions. The command processor 224 continues to service command messages until the remote device 211 logs off 227. Upon transmission and receipt by the host PC 213 of a log off message 227 of a remote device 211, the host PC 213 discontinues processing commands and destroys the action map.
FIG. 6A is a sequence diagram showing an alternative flow when an external switch, or actuator 210 is the source of the activation. The external switch actuator is connected to the remote wireless device 211 via serial communication cable 209. The user initiates operation by pressing the actuator button 210. Upon engagement by the user 248, the actuator 210 changes a pin condition on the serial connection 209. This event is recognized by the remote wireless device software 240. The remote device software 240 references a map that indicates the location identifier 249 to be transmitted to the host PC 213. The remote device 211 transmits the location identifier to the host PC 213.
According to one embodiment of this invention, the host PC 213 supports a multiple number of remote wireless devices 211 restricted only by the underlying limitations of the hardware and operating system (wireless transmitter 204, processor 203).
According to one embodiment, as stated above, the command processing of MIDI data involves the use of a known communication music computing standard called a Musical Instrument Digital Interface (“MIDI”). According to one embodiment, the operating system 250 provides a library of preset MIDI sounds. As is understood in the art, each MIDI command is sent to the MIDI driver (not shown part of the operating system 250) of the host PC 213. The MIDI driver directs the sound to the sound card 202 for output to the speaker 201.
Alternatively, the MIDI command is redirected by the MIDI driver to an external MIDI sound module 212. The MIDI sound module may be any commercially-available MIDI sound module containing a library of audio tones. The MIDI sound module 212 generates a MIDI sound output signal which may be directed to the speakers 201.
FIG. 7 is a sequence operational diagram depicting system operation in ensemble mode. In ensemble mode, the host PC 213 manages a real-time performance of one or more users. The music performed is defined in an external data file using the standard MIDI file format. The remote device 211 start up and log on sequence is identical to the sequence illustrated in FIG. 6. The change to ensemble mode takes place on the host PC 213. A system administrator selects a MIDI file to perform 230. The host PC 213 opens the MIDI file and reads in the data 231. The MIDI file contains all of the information necessary to playback a piece of music. This operation 231 determines the number of needed performers and assigns music to each performer. Performers may be live (a logged on performer) or a substitute performer (computer). The music assigned to live performers considers the performers ability and assistance needs (assessment profile). The system administrator selects the tempo for the performance and starts the ensemble processing 235. The host PC 213 and the remote wireless device 211 communicate during ensemble processing and offer functionality to enhance the performance of individuals that require assistance with the assigned part. These enhancements include visual cueing 234, command filtering, command location correction, command assistance, and command quantization 251. Visual cueing creates a visual cue on the remote device LCD 244 alerting the performer as to when and where to press the remote device LCD 244. In one embodiment, the visual cue may be a reversal of the foreground and background colors of a particular region of the remote device LCD 244. The visual cueing assists performers that have difficulty reading or hearing music. Using the MIDI file as a reference for the real-time performance, the command sequence expectation is known by the host PC 213 managing the performance. This enables the ensemble manager to provide features to enhance the performance. The command filter ignores out of sequence commands or commands that are not relevant at the time received within the performance. Command location correction adjusts the location identifier when the performer errantly presses the remote device LCD 244 at the incorrect x-y coordinate or region.
