TECHNICAL FIELD The present invention relates to a piano teaching assistance device that helps beginners or people with disabilities learn keyboard operations directly from a piano teacher. More particularly, the present invention relates to a piano teaching aid capable of showing the keys pressed by the teacher on the piano keyboard of the piano teacher in colors, characters and/or figures on the piano keyboard of the student using a projection device.

Piano is a popular activity for men and women of all ages. It is also said that by playing musical instruments, people with intellectual disabilities, developmental disabilities, mental disabilities, and age-related disabilities such as dementia can recover and improve their mental and physical health. Learning to play the piano has been incorporated into outpatient nursing care and after-school care for children with disabilities.

The first step in learning the piano is to memorize and play the note names (do-re-mi-fa-so-ra-shi-do). He taught me the name of the sound (do-re-mi-fa-so-ra-shi-do). However, in this case, children and people with disabilities may become bored and may not be able to continue learning the piano. In particular, it is difficult for children with disabilities, who often have visual predominance, to understand verbal instructions. It is thought that the dullness and incomprehensibility led to boredom.
Furthermore, as an aid for memorizing and playing the note names (do-re-mi-fa-so-ra-shi-do), colored sticky notes or sticky notes with the name of the pitch are pasted on the piano keyboard and taught, but there are limits to this.

On the other hand, as a device used for piano learning, there is a device that connects the electronic keyboard instruments of the teacher and the students, and displays the keys pressed by the teacher on the electronic keyboard instruments of the students in real time by means of guide lamps (Patent document 1) It requires a dedicated electronic keyboard instrument, and cannot be retrofitted to an already owned piano. There is also a fingering guide device for a musical instrument that connects an automatic performance device and a projector and projects finger shapes corresponding to the automatic performance onto the keyboard (Patent Document 2). However, it is not a device for assisting the piano teacher when teaching, but it has become a complicated device having an automatic performance device. Furthermore, it is positioned as a device for intermediate players to learn how to use the fingerings of the piano, and is not suitable for beginners.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a device that helps a beginner or a handicapped person to learn how to operate a keyboard directly from a piano teacher, and that can be retrofitted to a piano and is not complicated.

As a result of various investigations to achieve the above object, the inventor of the present invention used a device capable of projecting colors, characters, and/or graphics onto a piano keyboard in response to keyboard operation information input from a small keyboard. By doing so, the inventors have found that a beginner or a handicapped person can continuously learn keyboard operation without getting bored, and that such a device can be retrofitted to a piano and can be a simple device, and have arrived at the present invention. That is, the present invention is as follows.

1. A piano training assistance device consisting of a small keyboard as an input device, an information processing device that converts keyboard operation information generated by the small keyboard into image information, and a projection device that projects an image onto a piano keyboard based on the image information. In the projected image, colors, characters, and/or graphics can be displayed for each key of the piano keyboard to be projected. Displaying colors, characters and/or graphics on the corresponding keys of (I), changing the color of the corresponding keys on the piano keyboard, moving characters and/or moving graphics (II), of (I ) (II) A piano teaching aid capable of indicating on the keyboard of a piano the keys pressed on the miniature keyboard by combining either one or both.

According to the piano training assistance device of the present invention, when learning keyboard operation directly from a piano instructor, beginners and persons with disabilities can learn continuously without getting bored, and can effectively proceed with initial piano training. can be done. Moreover, it can be retrofitted to existing pianos, and the device itself can be uncomplicated.

An example of the piano teaching aid device of the present invention is shown. A piano keyboard displaying different colors and different note names for each key of the piano keyboard is shown. A piano keyboard displaying a different figure for each key of the piano keyboard is shown.

The present invention will be described in detail below.
An example of an embodiment of the invention is shown in FIG. In the piano learning aid device of the present invention, when the piano instructor presses a key on the small keyboard 1 , keyboard operation information is generated and transferred to the information processing device 2 . The information processing device 2 converts the keyboard operation information into image information. This image information is transferred to the projection device 5 via the wireless LAN device 3 and the display device 4, and the key corresponding to the key pressed by the lecturer on the keyboard of the student's piano 6 to be projected is colored. The image is projected such that , characters, and/or graphics are displayed. In this way, the keys pressed by the teacher can be shown on the student's piano keyboard in real time.

A small keyboard 1 used in the present invention is an input device, and the lecturer inputs keyboard operation information by operating the keyboard. It is not essential to connect the speaker 7 since it is not necessary to produce sound by operating the miniature keyboard. It is preferable that the size of the miniature keyboard is at the edge of the planar space on which the music board of the piano rests. More specifically, it is preferable that the horizontal width is equal to or less than 1/2 of the piano keyboard. The piano teacher instructs the students how to operate the keyboard by operating a small keyboard by the side of the students who are sitting facing the piano.

The keyboard operation information generated by the small keyboard 1 is information related to keyboard operation, and includes information such as pressed keys and their strength, but at least information about which keys are pressed and which keys are released is necessary. be. For example, a MIDI (registered trademark) signal corresponds to keyboard operation information.
Keyboard operation information is transferred from the small keyboard to the information processing device 2 . The transfer may be done by wire or wirelessly, but it is more preferable if it is wireless so that the small keyboard can be moved freely. For wireless, for example, the Bluetooth (registered trademark) LE wireless standard can be used.

The information processing device 2 converts the transferred keyboard operation information into image information. This information processing device is, for example, a tablet terminal or a personal computer.
The converted image information is image information that can display colors, characters, and/or graphics for each key of the piano when an image based thereon is projected onto a piano to be projected.

Image information is transferred to the projection device 5 via the wireless LAN device 3 and the display device 4 . The wireless standard at this time is not particularly limited. For example, when an iPad (registered trademark) manufactured by Apple Inc. is used as the information processing device 2, the AirPlay protocol (registered trademark) can be used. A general wireless router can be used as the wireless LAN device. A display device, also called a streaming device, is a terminal that receives streaming distribution of contents such as moving images from the Internet or wireless LAN and displays the contents on a television or the like. If it is manufactured by Apple Inc., Apple TV (registered trademark) can be used. By sequentially reproducing the image information by streaming distribution, the image can be changed and projected on the keyboard of the piano 6 in real time in conjunction with the information input by the small keyboard 1.例文帳に追加The display device and the projection device can be connected by HDMI (registered trademark), for example. This connection may be performed wirelessly using an HDMI (registered trademark) cable or using an HDMI (registered trademark) transmitter/receiver, but is preferably performed wirelessly.

Here, it is not essential to use the wireless LAN device 3 and the display device 4, as long as the projection device can directly receive the image information generated by the information processing device and project the image information on the piano keyboard in real time. If so, that's fine.
Also, the connection between devices may use a wired LAN instead of a wireless LAN.

According to the transferred image information, the projection device 5 projects an image onto the keyboard of the student's piano 6 (for example, FIGS. 2 and 3. In FIG. 3, the keyboard of the image and the piano keyboard are out of alignment). adjusted to match and used). In other words, if the information processing device 2 has a screen, the screen is projected onto the piano keyboard as it is, which is a projection method similar to project mapping rather than projecting onto a dedicated screen.
The projected image can display colors, characters, and/or graphics for each key of the piano keyboard. When displaying colors, according to the patent application of one of the applicants (Japanese Patent Application No. 2018-028817), adjacent keys are used to display warm colors, cool colors, and neutral colors ranging from yellowish green (GY) to green (Y). , purple (P) to reddish purple (RP) should not be continuous.
In order to display colors, characters and/or graphics for each key of the piano keyboard, it is possible to display colors, characters and/or graphics for each key of the keyboard of the image, and a keyboard of the projected image and piano keyboards, or at least the boundaries between the keys of both keyboards. When the keyboard is out of alignment between the projected image and the actual piano (for example, FIG. 3), the information processing device 2 determines the horizontal and vertical positions of the keys in the overall image, and furthermore, determines the width and length of the keys. to be able to tweak the length of to make them match. By doing this, the information processing device can eliminate the deviation of the boundaries between the keys of the projected image and the actual piano without moving the projection device itself.
It should be noted that the key is basically displayed with a color, character, and/or figure for each white key, but may be displayed for each white key and each black key. The graphics also include symbols, pictures, and patterns. Some students like certain characters and vehicles, and some people with disabilities dislike certain colors, so colors, letters, and/or graphics are freely selected to suit the preferences of the student or person with disabilities. can do.

As described above, it is possible to change the image on the piano keyboard in real time in conjunction with the information input from the small keyboard 1, and display colors, characters, and/or graphics for each piano key. . In addition, you can change the color in real time in conjunction with the pressing of each key on the small keyboard, and you can also move characters and figures. You can make characters and figures fall from the back to the front for each key, or bounce. As a result, by pressing a key on the small keyboard, a color, character, and/or figure is displayed on the corresponding key of the piano keyboard to be projected in real time, and furthermore, the color displayed on the key changes. , characters, and figures will move to visually indicate in real time which key the instructor has pressed. Just to make sure, it is also possible to use a combination of displaying, changing, and moving, such as characters and figures moving at the same time as they are displayed.
As described above, unlike the conventional method of sticking a sticky note on a keyboard, this device can emphasize the position of a pressed key in real time. Also, as for the method of emphasis, a plurality of patterns such as various colors, characters, and/or graphics, and one or more movements thereof are prepared so that the students can select according to their needs.

Here, children with disabilities are often visually dominant, and it is difficult for them to communicate verbal instructions. The child cannot concentrate and becomes bored. However, if this device, which can visually indicate keyboard operations, is used, instructions as to which keys should be pressed become clear, eliminating the difficulty of understanding for children with disabilities.
Furthermore, when teaching on a single piano, the piano teacher and the student cannot press the same keyboard at the same time, so the instruction is given with different positions and different sounds, such as octave up and down. It becomes very difficult for children to understand. If two pianos are used, it would be even more confusing. However, by using this device, it becomes possible to give an accurate instruction of "here and now" in real time, and the above difficulty in understanding can be eliminated.

To explain this device in more detail, for example, an image can be projected to display different colors, different musical notes, and figures for each key of a piano keyboard (Figs. 2 and 3; Fig. 3 shows an image keyboard). and piano keyboard). I don't know because it's a gray scale, but in Fig. 2, the colors "red, yellowish green, red, blue, yellow, purple, light blue, and red" are displayed for each key of the pitch name (do re mi fa so la shi do). there is Also, the letter "So" is hard to see in the figure due to the yellow color of the key, but it is actually displayed.
When using this device, for example, when a piano teacher does not press a key, only the image of the keyboard is projected, and the syllable name and color are not displayed. When the teacher presses the do key on the small keyboard, the "do character" is displayed in real time at the student's piano keyboard at the do position, and the entire do key turns red. The student can learn the position of the C key by looking at this and pressing the C key. When the key of the small keyboard is released, the "do character" disappears, and the red color of the key also disappears.
Furthermore, the syllable name and figure corresponding to each key are displayed in advance as shown in Figs. A "figure" may indicate the position of the key by jumping back and forth on the key. In this case, when the key of the small keyboard is released, the movement of the ``do character'' and the ``corresponding figure'' stops.

There is no restriction on the installation position of the projection device, but some people with disabilities cannot concentrate on piano learning if the projection device is in their field of vision. It is more preferable to keep it out of sight.
Further, it is more preferable to use a projector that operates quietly, and when using a projector, it is more preferable to use a silent projector.
Furthermore, if the present invention is used, an image is only projected onto the keyboard of the piano, and there is no need to modify the piano itself.

INDUSTRIAL APPLICABILITY According to the piano training aid device of the present invention, a beginner or a handicapped person can continuously learn how to operate a piano keyboard without getting bored. , manufactures and sells pianos, and is useful for the piano industry.
