Technical Field

This technology simulates human senses such as vision, hearing, and touch in virtual space, bringing users an unprecedented strong interactivity with the virtual world and a fully immersive and shocking experience in virtual space.

[0003] However, current navigation applications mainly navigate users by broadcasting key prompts such as "turn left" and "turn right" via voice. While this method can meet users' needs for navigation functions, it cannot provide users with a more realistic and immersive experience. Summary of the Invention

[0079] The technical solutions of this disclosure will be further described in detail below with reference to the accompanying drawings and specific embodiments. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit this disclosure. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0080] The terms "first," "second," etc., used in this disclosure and in the claims are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this disclosure can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0081] Traditional navigation applications primarily guide users through voice prompts such as "turn left" and "turn right." While this method effectively meets users' navigation needs, in today's rapidly evolving technological landscape, with constant iterations and upgrades, improving the user experience of traditional navigation services remains a pressing issue. For example, when using traditional navigation applications, audio-related services such as music playback are interrupted because the software requires audio output devices to play prompts, thus pausing other audio-related services. Furthermore, in the VR field, current technology mainly creates a three-dimensional (3D) immersive experience from a visual perspective. However, improvements from an auditory perspective are currently lacking. Introducing spatial audio technology into VR would significantly enhance the user experience, providing a more realistic and immersive experience.

[0082] This disclosure provides a spatial audio navigation method that differs from traditional navigation applications that rely on voice broadcasts or video displays. In this method, users can identify their destination based on the direction of sound. For example, when turning left, the user perceives the audio source as coming from the left; when going straight, the sound comes from the front; and the same applies when turning right. This disclosure provides users with a more realistic and immersive spatial audio experience.

[0083] The technical solutions provided by the embodiments of this disclosure are described in detail below with reference to the accompanying drawings.

[0084] Figure 1 This is a schematic flowchart illustrating a spatial audio navigation method provided in an embodiment of this disclosure. See also... Figure 1 The spatial audio navigation method provided in this disclosure may include the following steps:

[0085] Step 110: Obtain the current position of the target object and the target position input by the target object;

[0086] Step 120: Determine the location of the key intersection based on the current location and the target location;

[0087] Step 130: Based on the location of the key intersection, calculate the target distances from the two key points of the target object to the key intersection;

[0088] Step 140: Determine the target sound intensity corresponding to each of the two key points based on the target distance;

[0089] Step 150: Based on the target sound intensity, control the audio output device of the target object to output an audio signal.

[0090] In this embodiment of the disclosure, the above-described audio navigation control method can be applied to a mobile device, which can provide navigation information in the form of audio to guide the user to the target location. The mobile device may include: mobile phones, tablets, smartwatches, head-mounted displays (HMDs), etc., and this embodiment of the disclosure does not impose any limitations.

[0091] It should be noted that the spatial audio navigation method provided in this disclosure can be applied not only to navigation scenarios but also to cultural and tourism scenarios. Tourist attractions or museums and other cultural and tourism venues are typically equipped with audio-based attraction introductions. Tourists can listen to the explanations while navigating to the next attraction based on the spatial characteristics of the audio, thus making better use of audio resources and providing users with a more realistic 3D immersive experience.

[0092] In step 110, the target object can be an object using spatial audio navigation, such as a user using a mobile device for spatial audio navigation. The current location can be determined directly by the positioning module of the mobile device; the target location can be input by the target object through the mobile device.

[0093] For example, the target location can be the location of a place, a person, or an item (e.g., a set of keys). In this case, the target location can be any location on a map displayed by a navigation application on a mobile device during navigation.

[0094] In step 120, the key intersection can be the next intersection on the navigation route determined based on the current location and the target location; for example, if a user needs to go to destination A, the navigation application determines the user's current location B and the navigation route C to destination A, and the key intersection is the next intersection on the navigation route C that requires "left turn", "right turn" or "go straight".

[0095] It should be noted that the location of key intersections can be represented in the form of latitude and longitude coordinates.

[0096] In step 130, the target object can be a user, and the two key points of the target object can be the user's two ears; the target distance can include the target distance from the user's left ear to the key intersection, and the target distance from the user's right ear to the key intersection.

[0097] In this embodiment of the disclosure, the determination of the target distance in step 130 can be achieved in various different ways.

[0098] The following is a specific implementation example. It should be noted that the examples listed below are merely examples and are not intended to be limiting.

[0099] Step 130, which calculates the target distances from the two key points of the target object to the key intersection based on the location of the key intersection, may include:

[0100] When the target object turns at the key intersection in the first direction, the specified distance from the target object to the key intersection is taken as the target distance from the first key point to the key intersection among the two key points; and the sum of the specified distance and the distance between the two key points is taken as the target distance from the second key point to the key intersection among the two key points.

[0101] When the target object turns to the second turn at the key intersection, the specified distance from the target object to the key intersection is taken as the target distance from the two key points to the key intersection respectively.

[0102] In this way, the target distance can be calculated from the two key points to the key intersection by taking the position of the target object as the position of the first key point or the positions of the two key points, thus simplifying the calculation of the target distance within the allowable error range of the target distance calculation accuracy.

[0103] In this embodiment, the first turn can be a left turn or a right turn. In practical applications, the position coordinates of the target object can be directly taken as the position coordinates of the first key point among the two key points of the target object. Then, the specified distance from the target object to the key intersection can be taken as the target distance from the first key point to the key intersection, which simplifies the calculation of the target distance within the allowable error range. Furthermore, since the target distance from the first key point to the key intersection, the distance between the two key points, and the target distance from the second key point to the key intersection can form a triangle and constitute the three sides of the triangle, based on the relationship of the three sides of the triangle, taking the specified distance and the sum of the distances between the two key points as the target distance from the second key point to the key intersection simplifies the calculation of the target distance within the allowable error range of the target distance calculation accuracy.

[0104] In one implementation, the target object can be a user, and the two key points of the target object can be the user's ears. When the first turn is a right turn, the specified distance from the user to the key intersection is taken as the target distance from the user's right ear to the key intersection; and the sum of the specified distance and the distance between the user's ears is taken as the target distance from the user's left ear to the key intersection.

[0105] For example, such as Figure 2 As shown, it illustrates the distance relationship between the target object and the key intersection when the target object turns right at the key intersection.

[0106] Specifically, such as Figure 2 As shown, a virtual speaker 310 can be placed at the right front intersection so that users can perceive the sound as coming from the virtual speaker 310. Figure 2 A virtual speaker 310 can be used to represent the location of a key intersection. Similarly, all virtual speakers mentioned below can represent the location of key intersections. When the target object turns right at the key intersection, the user's right ear 350 is closer to the virtual speaker 310 than the left ear 360. Therefore, the specified distance from the user to the key intersection can be directly used as the target distance 320 from the right ear to the key intersection. Conversely, the left ear 360 is farther from the virtual speaker 310 than the right ear 350. To simplify calculations, the sum of the target distance 320 between the right ear 350 and the virtual speaker 310 and the distance between the two ears 330 can be used as the distance 340 between the left ear 360 and the virtual speaker 310. The user's distance between their ears 330 is approximately 16-18 centimeters, which is the system default setting. Users can also customize the distance between their ears based on their own auditory perception.

[0107] In one implementation, the target object can be a user, and the two key points of the target object can be the user's ears. When the first turn is a left turn, the specified distance from the user to the key intersection is taken as the target distance from the user's left ear to the key intersection; and the sum of the specified distance and the distance between the user's ears is taken as the target distance from the user's right ear to the key intersection.

[0108] For example, such as Figure 3 As shown, it illustrates the distance relationship between the target object and the key intersection when the target object turns left at the key intersection.

[0109] Specifically, the same applies to right turns, such as... Figure 3As shown, when the target object turns left at the key intersection, the user's left ear 460 is closer to the virtual speaker 410 than the right ear 350. The specified distance from the user to the key intersection can be directly used as the target distance 440 from the left ear 460 to the virtual speaker 410. The target distance 420 between the right ear 350 and the virtual speaker 410 can be obtained by summing the target distance 440 between the left ear 460 and the virtual speaker 410 with the distance between the two ears 430.

[0110] In this embodiment, the second turn can be straight-ahead. In practical applications, similar to the first turn, the position coordinates of the target object can be directly used as the position coordinates of two key points of the target object. Then, the specified distance from the target object to the key intersection can be used as the target distance from the two key points of the target object to the key intersection, which simplifies the calculation of the target distance within the allowable error range.

[0111] In one implementation, the target object can be a user, and the two key points of the target object can be the user's ears. When the second turn is straight ahead, the specified distance from the user to the key intersection is taken as the target distance from the user's ears to the key intersection.

[0112] For example, such as Figure 4 As shown, it illustrates the distance relationship between the target object and the critical intersection when the target object turns to go straight.

[0113] Specifically, such as Figure 4 As shown, when the target object is going straight at the key intersection, the distance between the user's left ear 560 and the virtual speaker 510 is the same as the distance between the user's right ear 550 and the virtual speaker 510. Therefore, the distance 540 between the left ear 560 and the virtual speaker 510 and the distance 520 between the right ear 550 and the virtual speaker 510 can both be the specified distance from the user to the key intersection.

[0114] In step 140, the target sound intensity may include the target sound intensity corresponding to the user's left ear and the target sound intensity corresponding to the user's right ear. The target sound intensity can reflect the sound volume at the two key points output to the target object.

[0115] Sound intensity, or simply sound strength, is defined in physics as the energy of a sound wave acting on a unit area perpendicular to its direction of propagation per unit time. In everyday life, the audible sound intensity ranges between a first threshold and a second threshold, with a difference of up to 10¹² times between the two thresholds.

[0116] Understandably, target distance and target sound intensity can be negatively correlated. That is, the greater the target distance, the lower the target sound intensity corresponding to the key point of the target object; or, the smaller the target distance, the greater the target sound intensity corresponding to the key point of the target object. In other words, the closer the key point of the target object is to the key intersection, the greater the sound intensity of the audio signal output by the corresponding audio output device. Thus, based on the same or different target distances, the same or different target sound intensities can be obtained.

[0117] In step 150, the aforementioned audio output device can be headphones worn by the user, such as wired headphones, wireless headphones, neckband headphones, and over-ear headphones, collectively referred to as headphones, or it can be the audio output device of a head-mounted display device. The audio file corresponding to the audio signal can be an audio source being played on the mobile device; when the mobile device is not using any audio-related application services, the audio file corresponding to the audio signal can also be any form of audio source stored on the mobile device, for example, it can be pleasant music, keywords such as "turn left" or "turn right" similar to those in traditional navigation systems, or other forms of audio resources.

[0118] In one embodiment, the specific control process for controlling the audio output device of the target object to output an audio signal can be: sending a target sound intensity to the audio output device so that the audio output device can output an audio signal of the target sound intensity to two key points of the target object based on the target sound intensity.

[0119] For example, the distance between the first key point of the target object and the key intersection can be R1, and the distance between the second key point of the target object and the key intersection can be R2. When R1 is less than R2, the target sound intensity corresponding to the first key point can be greater than the target sound intensity corresponding to the second key point; that is, the two key points of the target object can obtain audio signals with different sound intensities.

[0120] Here, the audio signal can be the audio signal output by the navigation application on the mobile device, or it can be the audio signal output by an application other than the navigation application on the mobile device. Therefore, in this embodiment of the disclosure, navigation services can be provided by utilizing the spatial effects generated by the audio signal being played by the audio output device, thereby solving the problem in traditional navigation methods where other audio services are interrupted after navigation is started.

[0121] The spatial audio navigation method provided in this disclosure acquires the current position of a target object and the target position input by the target object; determines the position of a key intersection based on the current position and the target position; calculates the target distances from two key points of the target object to the key intersection based on the position of the key intersection; determines the target sound intensity corresponding to each of the two key points based on the target distances; and controls the audio output device of the target object to output an audio signal based on the target sound intensity. In this way, the target sound intensity corresponding to each of the two key points of the target object can be determined by the target distances from the two key points of the target object to the key intersection, and the audio output device can be controlled to output an audio signal with the target sound intensity. This allows the two key points of the target object to receive audio signals with the same or different sound intensities, thereby generating a sense of direction from the audio signal and providing the target object with a more realistic and immersive spatial audio experience.

[0122] In one embodiment of this disclosure, the spatial audio navigation method provided by this embodiment may further include:

[0123] Determine the specified distance from the target object to the key intersection;

[0124] Based on the specified distance, determine the specified sound intensity corresponding to the specified distance;

[0125] Based on the specified sound intensity, the audio output device is controlled to output the audio signal.

[0126] In this embodiment of the disclosure, based on the current location of the target object and the location of the key intersection, a specified distance from the target object to the key intersection at the current moment can be determined. This specified distance can be determined by the positioning module of the mobile device.

[0127] The specified sound intensity is negatively correlated with the specified distance. That is, the greater the specified distance, the lower the corresponding specified sound intensity; conversely, the smaller the specified distance, the greater the corresponding specified sound intensity. In other words, the closer to a key intersection, the greater the sound intensity of the audio signal output by the corresponding audio output device.

[0128] In one embodiment, the specified sound intensity can be obtained by looking up a table showing the correspondence between a specified distance and a specified sound intensity, or it can be obtained by a calculation model of a specified distance and a specified sound intensity. This disclosure does not impose any limitations.

[0129] In this embodiment of the disclosure, the audio output device is controlled to output the audio signal based on a specified sound intensity. That is, as the distance between the user and the key intersection changes, the sound intensity of the output audio signal also changes accordingly. The user can clearly perceive that the sound intensity received by both ears changes continuously with the change in distance from the key intersection. For example, when the distance between the user and the key intersection decreases, the sound intensity of the output audio signal continuously increases; when the distance increases, the sound intensity of the output audio signal continuously decreases.

[0130] As can be seen, the embodiments of this disclosure not only simulate the directional effect of sound, but also the effect of sound distance change. Furthermore, in simulating the effect of sound distance change, the sound intensity of the output audio can be used to indicate whether the target object has deviated from the purpose of the key intersection, providing the target object with a more realistic and immersive spatial audio experience.

[0131] In one embodiment of this disclosure, the spatial audio navigation method may further include:

[0132] Determine whether the current position of the target object deviates from the critical intersection;

[0133] If the deviation distance of the target object from the critical intersection is greater than or equal to a preset distance, a warning sound will be output.

[0134] In this way, when the target object deviates from the preset distance of the key intersection, a warning sound can be output to remind the target object.

[0135] The preset distance can be customized; the warning sound can be the system default setting or a custom setting for the target object.

[0136] Understandably, if the deviation of the target object from the critical intersection is less than a preset distance, the target object can be prompted to deviate from the critical intersection by the intensity of the audio signal based on the negative correlation between the specified sound intensity and the specified distance; if the deviation of the target object from the critical intersection is greater than or equal to the preset distance, a warning sound can be output to further remind the target object that it has deviated from the critical intersection.

[0137] In this embodiment of the disclosure, step 140 can be implemented in various different ways.

[0138] The following is a specific implementation example. It should be noted that the examples listed below are merely examples and are not intended to be limiting.

[0139] Figure 5 This is a schematic flowchart illustrating a spatial audio navigation method provided in an embodiment of this disclosure. See also... Figure 5 The spatial audio navigation method provided in this disclosure may include the following steps:

[0140] Step 510: Obtain the current position of the target object and the target position input by the target object;

[0141] Step 520: Determine the location of the key intersection based on the current location and the target location;

[0142] Step 530: Based on the location of the key intersection, calculate the target distances from the two key points of the target object to the key intersection;

[0143] Step 540: Based on the preset first calculation model, input the target distance from the first key point to the key intersection among the two key points, and obtain the target sound intensity corresponding to the first key point;

[0144] Step 550: Based on the first calculation model, input the target distance from the second key point to the key intersection among the two key points, and obtain the target sound intensity corresponding to the second key point;

[0145] Step 560: Based on the target sound intensity, control the audio output device of the target object to output an audio signal.

[0146] In step 540, the preset first calculation model can be formula (1).

[0147] L p =L w -20log 10 rk (1)

[0148] Among them, L w It can represent the preset sound power; in the process of determining the preset sound power, it can be obtained through pre-training using the sound power calculation formula (2).

[0149] L w =L p0 +20log 10 r (2)

[0150] Among them, L p It can represent the target sound intensity (or sound pressure level), and the unit can be decibels (dB); L p0 It can represent the historical sound intensity; r can represent the target distance, which can be in meters; k can be a correction coefficient, which is k=11 in free space and k=8 in semi-free space.

[0151] In step 550, the target sound intensity corresponding to the second key point is calculated similarly according to formula (1) above.

[0152] It should be noted that the first key point can be the user's left ear, and the corresponding second key point can be the user's right ear; or, the first key point can be the user's right ear, and the corresponding second key point can be the user's left ear.

[0153] The spatial audio navigation method provided in this embodiment can be based on a first calculation model. By inputting the target distances from two key points to key intersections respectively, the target sound intensities corresponding to the two key points can be calculated respectively. This allows the target object to generate a sense of direction for the audio signal through the target sound intensities corresponding to the two key points, providing the target object with a more realistic and immersive spatial audio experience.

[0154] Figure 6 This is a schematic flowchart illustrating a spatial audio navigation method provided in an embodiment of this disclosure. See also... Figure 6 The spatial audio navigation method provided in this disclosure may include the following steps:

[0155] Step 610: Obtain the current position of the target object and the target position input by the target object;

[0156] Step 620: Determine the location of the key intersection based on the current location and the target location;

[0157] Step 630: Based on the location of the key intersection, calculate the target distances from the two key points of the target object to the key intersection;

[0158] Step 640: Based on the preset second calculation model, input the target distance from the first key point to the key intersection and the target distance from the second key point to the key intersection to obtain the sound intensity difference received by the two key points;

[0159] Step 650: Based on the turning of the target object at the key intersection, the sum of the preset initial sound intensity and the sound intensity difference is taken as the target sound intensity corresponding to the first key point, and the initial sound intensity is taken as the target sound intensity corresponding to the second key point.

[0160] Step 660: Based on the target sound intensity, control the audio output device of the target object to output an audio signal.

[0161] In step 640, the preset second calculation model can be formula (3).

[0162] L p1 -L p2 =20log 10r2 / r1 (3)

[0163] Among them, L p1 -L p2 It can represent the difference in sound intensity; r1 can represent the target distance from the first key point to the key intersection, and r2 can represent the target distance from the second key point to the key intersection; L p1 L can represent the target sound intensity corresponding to the first key point. p2 It can represent the target sound intensity corresponding to the second key point.

[0164] It should be noted that formula (3) can be obtained from formula (2). Specifically, input r1 and L into formula (2). p1 , and r2 and L p2 We can obtain: L p1 +20log 10 r1=L p2 +20log 10 r2, which gives formula (3).

[0165] In one implementation, such as Figure 7 As shown, this illustrates the relationship between the sound intensity difference and the ratio of the target distances corresponding to two key points. Specifically, the curve shows that the greater the difference in target distances between the two key points, the greater the resulting sound intensity difference. For example, as... Figure 7 As shown, when the target distance r2 is twice the target distance r1, the target sound intensity received by the second key point of the target object will be attenuated by 6dB compared with the target sound intensity received by the first key point.

[0166] In step 650, the initial sound intensity can be the sound intensity of the audio signal output by the audio output device in the initial state customized for the target object. The first key point can correspond to the direction of turn. For example, when turning left, the first key point can be the user's left ear; when turning right, the first key point can be the user's right ear.

[0167] For example, when the turn is left, the target sound intensity corresponding to the user's left ear can be the result of adding the sound intensity difference to the initial sound intensity; the target sound intensity corresponding to the user's right ear can be the initial sound intensity.

[0168] When the turn is right, the target sound intensity corresponding to the user's right ear can be the result of adding the sound intensity difference to the initial sound intensity; the target sound intensity corresponding to the user's left ear can be the initial sound intensity.

[0169] When the target object is going straight at a key intersection, the target sound intensity corresponding to the two key points of the target object is the same, that is, both can be the initial sound intensity.

[0170] The spatial audio navigation method provided in this embodiment can be based on a second calculation model. By inputting the target distance from two key points to a key intersection, the difference in sound intensity received by the two key points can be calculated. This allows for a more flexible determination of the target sound intensity corresponding to the two key points of the target object, thereby generating a sense of direction for the audio signal and providing the target object with a more realistic and immersive spatial audio experience.

[0171] In this embodiment of the disclosure, step 150 can also be implemented in various different ways.

[0172] The following is a specific implementation example. It should be noted that the examples listed below are merely examples and are not intended to be limiting.

[0173] In one embodiment, step 150, which involves controlling the audio output device of the target object to output an audio signal based on the target sound intensity, may include:

[0174] When the target sound intensity corresponding to the first key point among the two key points of the target object is less than or equal to the first preset sound intensity, the audio signal of the first preset sound intensity is output to the first key point through the audio output device, and the audio signal of the second preset sound intensity is output to the second key point among the two key points.

[0175] Wherein, the second preset sound intensity is greater than or equal to the target sound intensity corresponding to the second key point.

[0176] It should be noted that the first preset sound intensity can be the lower limit of the target sound intensity, and can be customized according to the actual application situation. This embodiment of the disclosure does not impose any restrictions.

[0177] Understandably, if the target sound intensity corresponding to the first key point of the two key points of the target object reaches the lower limit value first, the target sound intensity corresponding to the second key point of the two key points will no longer decrease; that is, the target sound intensity corresponding to the first key point can be the first preset sound intensity, and the target sound intensity corresponding to the second key point can be the second preset sound intensity, that is, the sound intensity is increased or remains unchanged based on the original target sound intensity corresponding to the second key point.

[0178] It should be noted that the first key point can be the user's left ear, and correspondingly, the second key point can be the user's right ear; or, the first key point can be the user's right ear, and correspondingly, the second key point can be the user's left ear.

[0179] In this way, by setting the lower limit of the target sound intensity corresponding to the two key points of the target object, it can be ensured that the target sound intensity received by the two key points of the target object is always different, and the problem of interruption of spatial audio navigation service due to low sound intensity can be effectively avoided, thus improving the user experience of the target object.

[0180] In one embodiment, step 150, which involves controlling the audio output device of the target object to output an audio signal based on the target sound intensity, may include:

[0181] If the target sound intensity corresponding to the first key point among the two key points of the target object is greater than the third preset sound intensity, the audio output device outputs the audio signal of the third preset sound intensity to the first key point and outputs the audio signal of the fourth preset sound intensity to the second key point among the two key points.

[0182] The fourth preset sound intensity is less than or equal to the target sound intensity corresponding to the second key point.

[0183] It should be noted that the third preset sound intensity can be the upper limit of the target sound intensity, and can be customized according to the actual application situation. This embodiment of the disclosure does not impose any restrictions.

[0184] Understandably, if the target sound intensity corresponding to the first key point of the two key points of the target object reaches the upper limit value first, the target sound intensity corresponding to the second key point of the two key points will no longer increase; that is, the target sound intensity corresponding to the first key point can be the third preset sound intensity, and the target sound intensity corresponding to the second key point can be the fourth preset sound intensity, that is, the sound intensity is reduced or remains unchanged based on the original target sound intensity corresponding to the second key point.

[0185] It should be noted that the first key point can be the user's left ear, and correspondingly, the second key point can be the user's right ear; or, the first key point can be the user's right ear, and correspondingly, the second key point can be the user's left ear.

[0186] In this way, by setting the upper limit of the target sound intensity corresponding to the two key points of the target object, it can be ensured that the target sound intensity received by the two key points of the target object is always different, and the damage caused to the two key points of the target object due to the high sound intensity can be effectively prevented, thus improving the user experience of the target object.

[0187] Additionally, it should be noted that when the target sound intensities corresponding to the two key points of the target object are both greater than the first preset sound intensity and less than or equal to the third preset sound intensity, the audio signal of the target sound intensity can be directly output to the two key points through the audio output device. In other words, when the target sound intensities corresponding to the two key points of the target object are both between the upper and lower limits, the target sound intensities corresponding to the two key points can be output normally. The target sound intensities can be calculated according to steps 310-320 or steps 410-420.

[0188] Specifically, the formula for calculating the sound intensity of the audio signal output by an audio output device can be as follows:

[0189]

[0190] Among them, L p 'L can be the sound intensity of the audio signal output by the audio output device.' p L can represent the target sound intensity corresponding to two key points of the target object. pmin The first preset sound intensity can be set to L. pmax A third preset sound intensity can be set.

[0191] To facilitate understanding, the specific process of the spatial audio navigation method provided in this disclosure embodiment will be further described in detail below, combined with practical application scenarios:

[0192] For example, a user first opens a navigation service application on their mobile device, which then locates their current position. After the user inputs their target location, the application provides the optimal route from their current location to the target location, including the locations of key intersections. The mobile device can control the user's audio output devices, such as headphones or a headset, causing differences in the audio signals output to the user's ears. This allows the user to perceive the directionality of the sound and uses this directionality for navigation. As the user moves, guided by spatial sound, their location information is continuously updated through the navigation service application, along with the location information of key intersections. The mobile device then adjusts its control over the audio output devices accordingly, making the user perceive a change in the intensity of the sound played by the audio output devices as the distance decreases, thus psychologically perceiving a change in distance from the destination.

[0193] Mobile devices can control audio output devices worn by users by mimicking the human ear's ability to determine sound direction based on the time difference in sound arrival at both ears. Specifically, by calculating the distance between the user's ears and key intersections, and using a model relating distance to sound intensity, the device can ensure that each ear receives audio signals of different intensities, thus creating a sense of sound location. For example, if a user is about to turn left at a key intersection, the left ear, being closer to the intersection, receives a stronger sound, while the right ear, being farther away, receives a weaker sound. The audio output device outputs different intensities to the user's left and right ears, allowing the user to perceive the sound as coming from the left and turn left accordingly; the same logic applies to turning right. If the user needs to continue straight at a key intersection, the distance to both ears is the same, resulting in equal sound intensity for both ears, making the user perceive the sound as coming from directly ahead and prompting them to continue straight. This mapping relationship between distance and sound intensity simulates the human ear's ability to perceive changes in sound, aligning with the biological characteristics of the human ear and making spatial audio effects more realistic.
