[0002] Human-computer interaction (HCI) refers to the process of information exchange and communication between humans and computers; it is an interdisciplinary field encompassing computer science, psychology, engineering, and other disciplines. In situations such as speeches or public presentations, people typically need to use microphones to amplify their voices. Traditional microphones require speakers to prepare their own speeches and deliver them.

[0003] This type of speaking style can easily cause users to not be able to see the text content clearly or experience visual fatigue, affecting the visual effect and comfort, and can easily distract attention; it can also easily cause users to miss or repeat certain information, affecting the efficiency and fluency of the speech.

[0004] To address these issues, we propose a computer-controlled human-computer interaction device. Summary of the Invention

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0029] Example 1: This invention provides a technical solution: a computer-controlled human-computer interaction device, including a text display screen 3 that dynamically displays the size of text content based on computer control, a microphone 1, and a support 2 that supports the microphone 1. The bottom of the support 2 is fixedly connected to a support base 201 fixed on a desktop. The text display screen 3 is fixed on a synchronization ring 4. The text display screen 3 is also equipped with a camera 5 for visual observation of the user. A fixed plate 6 is fixed to the top of the support 2 on the side of the synchronization ring 4 away from the microphone 1. A base 1 7 and a base 2 8 are fixedly connected to the side of the fixed plate 6 near the microphone 1. The extension lines of the base 1 7 and the base 2 8 intersect on the axis of the fixed plate 6 and are perpendicular to each other. Each of the base 1 7 and the base 2 8 is equipped with a rotating component 9 fixedly connected to the surface of the synchronization ring 4. The microphone 1 is equipped with a support component 10 that rotates synchronously with the synchronization ring 4.

[0030] Microphone 1 picks up the user's speech and converts it into an electrical signal, which is then amplified by an amplifier and speakers.

[0031] The device is fixed to a desktop or lectern using the bracket 2 and the title display screen 3. The microphone 1 is fixed and supported by the synchronization ring 4 and the support component 10. After the synchronization ring 4 is driven to rotate, the microphone 1 rotates accordingly through the transmission of the support component 10, which improves the sound pickup effect and flexibility, avoids the monotony or distortion caused by being fixed in one position, and increases the dynamics and stereo effect of the recording. It also reduces the number of microphones and the trouble of switching, saving costs and space.

[0032] Distance measurement via camera 5 refers to using the camera to acquire distance information between the object and microphone 1. The principle is to use geometric relationships such as similar triangles or projection transformations to calculate the distance between the user and microphone 1 based on the changes in the size or position of the object in the image. The computer captures the user's line of sight and distance via camera 5. Based on the distance and angle between the user and the text display screen 3, the computer automatically calculates the appropriate text size and sends it to the text display screen 3 via a data cable, thus enabling the text display screen 3 to dynamically display the text size under computer control.

[0033] After determining the distance, the computer continuously and automatically adjusts the font size on the inscription display screen 3 so that users can clearly see the content displayed on the inscription display screen 3 at different distances.

[0034] At the same time, based on the content read by the user, the computer interacts with the information and controls the scrolling speed of the content on the title display screen 3 in real time;

[0035] The above content is existing technology well known to those skilled in the art, and is only described in this solution;

[0036] The combination of the fixed plate 6, base 1 7, base 2 8 and rotating component 9 enables dynamic support for the synchronization ring 4, allowing for follow-up operation with the user's mouth to achieve better sound pickup quality.

[0037] Furthermore, the support assembly 10 includes a chassis 11 fixed on the outer contour of the microphone 1. Two symmetrical extension arms 12 are fixedly connected to the arc-shaped contour of the chassis 11. A movable plug rod 13 is fixedly connected to the side of the extension arm 12 facing the fixed plate 6. The movable plug rod 13 axially passes through the synchronization ring 4 and is slidably connected to the synchronization ring 4.

[0038] refer to Figure 1 and Figure 2 The microphone 1 moves axially through the axial movement of the movable plug 13 on the synchronization ring 4, and is driven by the extension arm 12 and the chassis 11. This further assists the microphone 1 in more accurately following the user's mouth.

[0039] In embodiment 2, the rotating assembly 9 includes a shaft 14 that rotates on its inner wall at a fixed axis and is driven to rotate by a power mechanism. The shaft 14 is penetrated and fixedly connected to a rotating box 15. The inner wall of the rotating box 15 is fixedly connected to a shaft 16. The shaft 16 is penetrated and rotatably connected to a transmission rod 17. One end of the transmission rod 17 near the synchronous ring 4 is connected to another base 7 fixed on the synchronous ring 4.

[0040] The transmission rod 17 on the second base 8 is connected to another second base 8 fixed on the synchronous ring 4 at one end.

[0041] Working principle of Example 2:

[0042] refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 ;

[0043] The power mechanism drives shaft 14 to rotate within the base 7, and the direction of rotation of the fixed shaft is as follows: Figure 3As shown by arrow C, shaft 16 will rotate in the direction shown by arrow D within the rotating box 15 via transmission rod 17;

[0044] Arrows C and D are perpendicular to each other in three-dimensional space;

[0045] Through the cooperation of rotating box 15, shaft 16, and transmission rod 17, the synchronization ring 4 can ultimately rotate in the direction of arrow C. From an overall perspective, this achieves horizontal rotation of the synchronization ring 4 and microphone 1. When the user turns their head left or right, this follow-up method can quickly track the dynamic changes of the user's mouth in the horizontal direction. Rotation in the direction of arrow D does not interfere with the vertical movement of microphone 1.

[0046] The second base 8, which is perpendicular to the extension line of the first base 7, has a rotating arrow E on its upper shaft 14. Arrow E and arrow C are perpendicular to each other in space, and arrow E and arrow D are parallel to each other. Through the cooperation of the rotating box 15, shaft 16, and transmission rod 17 on the second base 8, the synchronization ring 4 can rotate the microphone 1 in the vertical direction. When the user speaks or gives a speech through the microphone 1, and makes a head-down or head-up movement, the microphone 1 can quickly swing up and down, thereby completing the follow-up operation in the vertical space.

[0047] The arrangement of two bases 8 and two bases 7 on the ends of the two transmission rods 17, as described above, makes the rotation between the fixed disk 6 and the synchronous ring 4 more flexible and less prone to movement restriction.

[0048] Furthermore, two bases 19 that are mirror-symmetrical to the base 2 8 and the transmission rod 17 thereon are fixedly connected between the opposite surfaces of the synchronization ring 4 and the fixed disk 6. A transmission assembly 20 is connected between the two bases 3 19, and the transmission assembly 20 corresponds one-to-one with the rotation assembly 9 and is identical to it.

[0049] By setting up two bases 7, 8, and 19 between the opposite surfaces of the synchronizing ring 4 and the fixed disk 6, as well as the rotating component 9 and the transmission component 20 inside them, the transmission connection between the synchronizing ring 4 and the fixed disk 6 is made more stable, symmetrical at three points, and has higher support strength.

[0050] Example 3 is basically the same as Example 2, except that the power mechanism includes a sealing shell 21 fixed to the surface of base 7 and base 8 and axially arranged with shaft 14 on base 7 and base 8. An arc-shaped electromagnet module is fixedly connected to the inner wall of the sealing shell 21. The arc-shaped electromagnet module includes electromagnet units 22 arranged in a non-completely circular pattern on the inner wall of the sealing shell 21. The surface of shaft 14 near the end penetrates the sealing shell 21 and extends into the sealing shell 21. A magnetic metal block 23 that magnetically engages with the electromagnet unit 22 is fixedly connected to the outer contour of the sealing shell 21.

[0051] refer to Figure 5 When the electromagnet unit 22 on the inner wall of the sealed shell 21 is powered on, it will generate a magnetic attraction to the metal. When the electromagnet unit 22 on the inner wall of the sealed shell 21 is powered on and then disconnected, the magnetic metal block 23 will rotate inside the sealed shell 21 with the shaft 14, thereby realizing the rotation of the shaft 14 and thus realizing the follow-up effect of the microphone 1 described above.

[0052] Furthermore, the central angle corresponding to the arc length of the arc-shaped electromagnet module inside the sealing shell 21 is 180 degrees, which corresponds to the maximum angle at which the user shakes their head left and right or tilts their head up and down.

[0053] Furthermore, the user's head shaking and tilting are linear operations, not jumping to another point in the air, but rather regular linear movement;

[0054] Therefore, the magnetic metal blocks 23 on the arc-shaped electromagnet module are also connected to the power supply in sequence, so that the electromagnet unit 22, which is far away from the current magnetic metal block 23, will not suddenly be connected to the power supply, causing the magnetic metal block 23 to be unable to complete the rotation operation normally.

[0055] In Example 4, based on Example 3, the microphone 1 is further provided with a sound sensor 24 for precise monitoring of spatial audio. There are twenty sound sensors 24, which are evenly distributed on the chassis 11. Five sound sensors 24 are located at the top and five at the bottom of the chassis 11, and they are electrically connected to the electromagnet units 22 in the sealed shell 21 on the base 2 8.

[0056] The sound sensor 24 is a component used to convert sound signals into voltage signals, and an electret condenser microphone can be selected.

[0057] The five sound sensors 24 located on the base 7 of the chassis 11 are corresponding to and electrically connected to the electromagnet units 22.

[0058] The aforementioned chassis 11 receives the strongest sound intensity when the user is facing a particular chassis 11. The chassis 11 is powered on via the electromagnet unit 22 corresponding to the circuit controller. When the electromagnet unit 22 is powered on, it generates magnetic attraction to attract the magnetic metal block 23 and cause the magnetic metal block 23 to rotate.

[0059] In this scheme, there is a certain damping between the magnetic metal block 23 and the electromagnet unit 22, so that it will not quickly reset due to gravity after power is cut off.

[0060] In this design, the circuit used between the sound sensor 24 and the electromagnet unit 22 is an analog circuit. The analog circuit is a component used to amplify, shape, compare, and output the sound signal. It can be composed of integrated circuits or discrete components. The switch is a component used to control the on / off state of the electromagnet according to the output signal of the analog circuit. It can be a unidirectional thyristor or a relay, etc. If the electrical properties of the sound sensor and the electromagnet unit are different, some converters or regulators are needed to ensure normal signal transmission.

[0061] Furthermore, two symmetrical bases 25 are fixedly connected to the opposite surfaces of the chassis 11 and the fixed plate 6. The two bases 25 are connected to transmission components 26 that are identical to and correspond one-to-one with the rotating component 9. The transmission rod 17 inside the transmission component 26 is passed through and axially fixedly connected to an electric push rod 27 controlled by a computer.

[0062] refer to Figure 6 When the user's rotation reaches an extreme point, the follow-up rotation of microphone 1 is insufficient to meet the actual usage needs. Microphone 1 is still some distance away from the user's mouth. At this time, based on the computer's visual information collection, and through the axial movement of electric push rod 27, the chassis 11 and microphone 1 are driven to move axially at the target angle, so that microphone 1 is closer to the user's mouth and achieves a better sound pickup effect.

[0063] Furthermore, a return spring 28, which is sleeved around the outer contour of the base 25, is fixedly connected to the opposite surfaces of the chassis 11 and the fixed plate 6.

[0064] The reset spring 28 provides elastic support for the chassis 11 and microphone 1, allowing them to slowly return to a horizontal position after the user stops speaking.

[0065] Working principle: This computer-controlled human-computer interaction device uses microphone 1 to pick up the user's speech and convert it into electrical signals, which are then amplified by an amplifier and speakers.

[0066] The device is fixed to a desktop or lectern using the bracket 2 and the title display screen 3. The microphone 1 is fixed and supported by the synchronization ring 4 and the support component 10. After the synchronization ring 4 is driven to rotate, the microphone 1 rotates accordingly through the transmission of the support component 10, which improves the sound pickup effect and flexibility, avoids the monotony or distortion caused by being fixed in one position, and increases the dynamics and stereo effect of the recording. It also reduces the number of microphones and the trouble of switching, saving costs and space.

[0067] Distance measurement via camera 5 refers to using the camera to obtain distance information between the object and microphone 1. The principle is to use geometric relationships such as similar triangles or projection transformations to calculate the distance between the object and microphone 1 based on changes in the object's size or position in the image. The computer captures the user's line of sight and distance via camera 5, and automatically calculates the appropriate text size based on the user's distance and angle from the text display screen 3. This is then sent to the text display screen 3 via a data cable, enabling the screen to dynamically display text size under computer control. After determining the distance, the computer continuously and automatically adjusts the font size on the text display screen 3 accordingly, ensuring that the user can clearly see the content displayed on the screen at different distances.

[0068] Simultaneously, based on the content read by the user, the computer interacts with and controls the scrolling speed of the content on the title display screen 3 in real time; through the cooperation of the fixed plate 6, base one 7, base two 8 and rotating component 9, dynamic support for the synchronization ring 4 is achieved, enabling follow-up operation with the user's mouth to achieve better sound pickup quality.

[0069] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
