Problems solved by technology

[0003] Compared with traditional music teaching, although the existing computer multimedia music teaching has great advantages, there are still many shortcomings: First, it is reflected in the limitations of input methods. Using computer multimedia music teaching, teachers are limited by the operation of the mouse and keyboard, which is not convenient Walking around randomly, body language is not rich enough, and it is inconvenient to interact with students at close range. The original colorful teaching has become a simple switch of PPT, and the quality of classroom teaching has declined
The second is reflected in the limitation of teaching equipment, which involves on-site demonstration courses of large musical instruments such as pianos. The existing computer multimedia teaching can only give students a sensory understanding, and the teaching needs to be carried out in a professional musical instrument room. Limited, only a small number of students can be accommodated, which brings great inconvenience to music teaching

Embodiment 1

[0029] Embodiment 1: the photoelectric pointer (6) that uses in the virtual electronic music teaching equipment of the present invention, its circuit is as Figure 4 , button battery (9) is connected in series with universal switch (10), bright photoelectric indicator light (5) and proximity switch (11) in the circuit, and proximity switch selects mechanical microswitch for use among the figure. For the photoelectric pointer used, the bright photoelectric indicator light is installed on the front side of the top of the photoelectric pointer, and the proximity switch is installed on the rear side of the top; when using the photoelectric pointer, first close the general switch, when the top of the photoelectric pointer approaches or touches the target position, the proximity switch is closed, The high-brightness photoelectric indicator lights up; when the top of the photoelectric pointer leaves the target position for a certain distance, the proximity switch is disconnected, and ...

Embodiment 2

[0030] Embodiment 2: The virtual electronic music teaching equipment of the present invention is used for virtual piano simulation teaching, and a new operation information input method is adopted in the teaching. The required equipment such as figure 1 , the hardware equipment mainly includes a photoelectric pointer (6), a sensor array (8), a mouse, a keyboard, a computer, MIDI, a sounding device, a projector and a projection screen. The used proximity switch (11) of the photoelectric pointer selects the capacitive proximity switch for use. The status of piano simulation teaching is as follows: figure 2 First, the computer controls the projector (1) to output a virtual image, which is projected onto the projection screen (2) to form a virtual staff (3) and virtual piano keys (4), and the teacher (7) clicks on the virtual piano on the projection screen through the photoelectric pointer Press the button, so that the bright photoelectric indicator light (5) at the top of the ph...

Embodiment 3

[0032] Embodiment 3: Utilize the virtual electronic music teaching equipment of the present invention to carry out the teaching demonstration of music score composition. refer to image 3 First, the computer controls the projector (1) to output a virtual image, which is projected onto the projection screen (2) to form a virtual stave (3), and the teacher (7) performs musical notes through the bright photoelectric indicator light (5) on the top of the photoelectric pointer (6) Pickup operation. Similar to the operation for the photoelectric pointer in embodiment 2, the sensor array (8) monitors the information of the position and state of the highlighted photoelectric indicator light all the time, records the note type that the current photoelectric pointer picks up, and carries out corresponding real-time monitoring by judging the teacher's operation type. response. If the teacher is picking up notes, update the type of notes picked up by the pointer; if the teacher is filli...

Abstract

The invention relates to virtual electronic music teaching equipment and an operation information input method thereof. The virtual electronic music teaching equipment comprises the following hardware: a photoelectric fescue, a laser lamp, a sensor array, a computer, a projector, a projection screen, an MIDI sound source board and sound making equipment. An industry control case is adopted to be convenient for mobile teaching, and the one-time investment cost is low. The common musical instruments are simulated on the projection screen through the projector, and the virtual electronic music teaching is performed by dint of the photoelectric fescue and the laser lamp and in combination with teaching software. Besides inputting information through a mouse and a keyboard, a teacher can also approach or contact the target with the photoelectric fescue, lighten a high brightness photoelectric indicating lamp, or indicate the target through the laser lamp; the sensor array captures the bright spots generated by the photoelectric fescue or the laser lamp as the operation information to replace the click and double-click function of the mouse, the position of the bright spots is corresponding to the position of the arrow of the mouse, and the brightening and the darkening of the bright spots are corresponding to the pressing and the bouncing of the key of the mouse. The invention has the advantages that various music teaching is integrated into a whole, the operation is flexible and convenient, the images can be displayed visually, and the invention is suitable for primary music teaching.

Description

technical field [0001] The present invention relates to a virtual electronic music teaching device and its operation information input method, specifically provides a virtual electronic music teaching device and a new operation information input method so that teachers are not limited by mouse and keyboard operations , use auxiliary teaching equipment and teaching software to conduct virtual electronic music teaching more conveniently. Background technique [0002] In recent years, computer music technology has had a great impact on music teaching and is gradually infiltrating into various fields of teaching. Computer multimedia music teaching has large capacity, good sound effects, strong visibility and high efficiency, allowing students to learn in a shorter time. Getting more and more beautiful edification in time is a good way to improve students' musical literacy. [0003] Compared with traditional music teaching, although the existing computer multimedia music teachin...
