Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, it will be appreciated by those of ordinary skill in the art that numerous technical details are set forth in order to provide a better understanding of the present application in various embodiments of the present invention. However, the technical solution claimed in the present application can be implemented without these technical details and various changes and modifications based on the following embodiments. The following embodiments are divided for convenience of description, and should not constitute any limitation to the specific implementation manner of the present invention, and the embodiments may be mutually incorporated and referred to without contradiction.
The first embodiment of the invention relates to a volume adjusting method, which is applied to electronic equipment, wherein the electronic equipment can be a terminal or a server, and the terminal can be a mobile phone, a tablet personal computer and other equipment. The application scenarios of the present embodiment may include, but are not limited to: the method comprises the steps of carrying out volume adjustment on video played by the terminal, carrying out volume adjustment on audio played by the terminal, carrying out volume adjustment on ringtone played by the terminal and the like. The following describes the implementation details of the volume adjustment method of the present embodiment in detail, and the following is only provided for the convenience of understanding and is not necessary for implementing the present embodiment.
A flowchart of a volume adjustment method in the present embodiment is shown in fig. 1, and includes:
step 101: and obtaining the density information of each position in the preset range.
The preset range is determined based on the position of the terminal, so that a user corresponding to the terminal can be located in the preset range. The user corresponding to the terminal can be understood as a user using the terminal, such as a user using the terminal to watch video, listen to music, and make and receive calls.
In one example, the preset range may be a sphere range in which any point on the terminal is a sphere center and r is a radius. Wherein r can be set according to actual needs, for example, the higher the height of the user, the larger r is. Referring to fig. 2, the predetermined range is a sphere range formed by taking the center of gravity of the terminal as the center of sphere and 2m as the radius. It should be noted that fig. 2 is only a schematic plan view corresponding to the sphere range provided for convenience of description, and in a specific implementation, the sphere range is a three-dimensional perspective view.
In another example, the preset range may be a square range with x as a side length and centered at any point on the terminal. Wherein x can be set according to actual needs, for example, the higher the height of the user, the larger x is.
In one example, a density detector may be pre-positioned within the terminal, the density detector being configured to detect density. The terminal can obtain density information of each position in a preset range through a built-in density detector; the density information at each position can be understood as: and density information of all points in the preset range, such as the density of all points, wherein all points in the preset range respectively have respective coordinates. The origin of coordinates may be set according to actual needs, for example, a central point of the preset range may be used as the origin of coordinates, however, other points within the preset range may also be used as the origin of coordinates according to actual needs, and the selection of the origin of coordinates is not specifically limited in this embodiment.
In a specific implementation, a human body and objects other than the human body may exist within a preset range, such as: the density information of the position of the human body can be the density of the human body, and the density information of the position of the object can be the density of the object.
In one example, the electronic device may obtain density information at each position within a preset range after detecting a preset trigger condition. The preset trigger condition may be set according to actual needs, and is used to indicate that the user wishes to start to automatically adjust the volume, for example, after the preset trigger condition is detected, a preset density detector in the terminal is turned on, and density detection is started to obtain density information at each position in a preset range.
In an example, the volume adjustment method in this embodiment is applied to an electronic device, where the electronic device is a terminal, and the terminal can directly obtain density information at each position in a preset range.
In another example, the volume adjustment method in this embodiment is applied to an electronic device, where the electronic device is a server, and after acquiring the density information, the terminal sends the acquired density information to the server, so that the server can receive the density information sent by the terminal.
Step 102: and determining the human body contour of the user corresponding to the terminal according to the density information.
It is understood that the obtained density information at each position within the preset range may include: the density of the position of the human body and the density of the position of the object. The electronic equipment can determine the position of the human body according to the acquired density information of each position in the preset range, and determine the human body contour of the user corresponding to the terminal according to the position of the human body. The terminal can determine the set of the target points with the density within the preset range being the density of the human body as the position of the human body. And drawing the human body contour of the user corresponding to the terminal according to each target point. Wherein, the human body contour can be a three-dimensional human body contour.
In one example, the height and the weight of the user can be input, and when the human body contour of the user is determined, the height and the weight of the user can be combined, so that the human body contour of the user can be determined more accurately and rapidly.
In one example, according to the density information, the manner of determining the human body contour of the user corresponding to the terminal may be as follows:
firstly, if it is determined that the user touches the terminal, the terminal is triggered to start somatosensory safe current. Wherein, if the terminal detects the grip value, it may be determined that the user touches the terminal, however, in a specific implementation, the manner of determining whether the user touches the terminal is not limited thereto. The body-sensing safe current started by the terminal is the safe current which can be borne by a human body, namely body-sensing weak current, so that the influence on the human body is avoided.
Then, an electrolytic reaction in which a somatosensory safe current enters each joint part of the user is determined, and the movement state of each joint part is determined based on the electrolytic reaction. It can be understood that different activity states of each joint part may correspond to different electrolytic reactions, and the corresponding relationship between the activity states and the electrolytic reactions may be pre-stored in the electronic device, so that the activity state corresponding to the electrolytic reaction of each joint part may be determined according to the corresponding relationship. The following is a brief description of the motion state using the elbow joint as an example:
the moving state of the elbow joint can comprise a bending and stretching angle and a rotating angle, wherein the bending and stretching is to straighten the arm and bend the arm, and the rotating is to pronate and supinate the forearm for controlling the palm of the hand to face downwards and upwards. The normal functional range is 135 degrees to 150 degrees of flexion, 80 degrees to 90 degrees of pronation or supination, 10 degrees to 15 degrees of hyperextension, the hyperextension is a physiological eversion angle, also called as an object carrying angle, and the hyperextension is obvious when a heavy object is lifted, so that a certain distance can be kept between a body and the heavy object. Therefore, when a user holds the terminal by hand and brings the terminal close to the ear of the person, the activity state of the elbow joint changes gradually, and the change of the activity state of the elbow joint can reflect the change of the position relation between the terminal and the ear of the person to a certain extent.
And finally, determining the human body contour of the user corresponding to the terminal according to the density information and the activity state. That is to say, the human body contour of the user corresponding to the terminal is determined by combining the density information and the activity states of the parts of the human body, and the human body contour can reflect the activity states of the parts of the human body, so that the dynamic human body contour can be obtained more easily, and the change of the position relationship between the terminal and the human ear can be determined more accurately.
Step 103: and determining the relative position of the terminal and the user according to the human body outline.
In one example, the human body contour is within a preset range, and since the preset range is determined based on the position of the terminal, the relative position of the terminal and the user can be determined according to the position of the human body contour in the preset range. For example, the relative position between the terminal and the user may be a separation distance between the terminal and the user, and if the separation distance is smaller, it may be considered that the terminal and the user are relatively close; if the separation distance is large, the terminal and the user can be considered to be relatively far away.
In one example, the implementation of step 103 may be as follows:
first, the head position of the user is determined according to the human body contour. It can be understood that the electronic device can roughly distinguish various parts of the human body, such as the head, the hands, the legs, and the like of the human body according to the human body contour. Therefore, the electronic device may determine the head position of the user according to the human body contour, the head position may be a coordinate of a center point where the head of the user is located, and the coordinate may be a three-dimensional coordinate. In a specific implementation, the position of the ear in the head of the user can be further determined according to the human body contour, and the position of the ear can be represented by the coordinate of the central point where the ear is located.
Then, the relative position of the terminal and the user's head is determined based on the head position and the position of the terminal.
In one example, the head position may be a three-dimensional coordinate of the head, from which the height of the head may be determined. The position of the terminal can be a three-dimensional coordinate of the terminal, and the height of the terminal can be determined according to the three-dimensional coordinate of the terminal. The three-dimensional coordinates of the head and the three-dimensional coordinates of the terminal are three-dimensional coordinates in the same coordinate system, the height of the head may be a Z-axis coordinate in the three-dimensional coordinates of the head, and the height of the terminal may be a Z-axis coordinate in the three-dimensional coordinates of the terminal. From the height of the head and the height of the terminal, the height difference between the terminal and the head of the user can be determined as the relative position of the terminal and the head of the user. If the height difference is small, the terminal can be considered to be relatively close to the head of the user; if the height difference is large, it can be considered that the terminal is relatively far from the head of the user. In another example, the height difference between the terminal and the ear of the user may be further determined according to the height of the ear in the head of the user and the height of the terminal, and the height difference may be used as the relative position between the terminal and the middle ear of the head of the user.
In another example, a horizontal distance of the terminal from the head of the user may be determined from the three-dimensional coordinates of the terminal and the head, and the horizontal distance may be taken as a relative position of the terminal and the head of the user.
Optionally, the spatial distance between the terminal and the head of the user may be determined according to the three-dimensional coordinates of the terminal and the head, and the spatial distance may be used as the relative position between the terminal and the head of the user.
In a specific implementation, the three-dimensional coordinates of the head may be three-dimensional coordinates of any point of the head, such as three-dimensional coordinates of a center point of the head. The three-dimensional coordinates of the terminal may be three-dimensional coordinates of any point in the terminal, such as three-dimensional coordinates of a center point of the terminal.
Step 104: and adjusting the volume of the terminal according to the relative position.
Specifically, if the distance between the terminal and the user is determined to be large according to the relative position of the terminal and the user, the volume of the terminal can be increased; if the distance between the terminal and the user is determined to be small according to the relative position of the terminal and the user, the volume of the terminal can be reduced. In a specific implementation, the separation distance may be proportional to the adjusted volume, that is, the larger the separation distance is, the larger the adjusted volume is, so that the user can hear the sound emitted by the terminal even if the user is far away from the terminal; the smaller the spacing distance is, the smaller the adjusted volume is, so that when the user is close to the terminal, the volume of the sound emitted by the terminal is not too large, and the hearing experience of the user is not influenced. The volume of the terminal may be the volume of a video played by the terminal, the volume of music played by the terminal, or the like. Optionally, in this embodiment, the volume of the terminal may be adjusted in real time according to the change of the relative position.
In one example, the separation distance between the terminal and the user may include: the vertical separation distance. The vertical separation distance may be a height difference between the terminal and the head of the user as described above, or may be a height difference between the terminal and the ear of the user as described above. In another example, the separation distance between the terminal and the user may include: a horizontal separation distance, which may be the horizontal distance of the head of the user as described above. Optionally, the separation distance between the terminal and the user may include: a spatial separation distance, which may be the spatial distance of the terminal from the head of the user as described above.
In one example, the terminal may determine whether the user holds the terminal, and adjust the volume of the terminal according to the relative position if it is determined that the user holds the terminal. The terminal can detect whether the terminal has grip strength, so as to determine whether a user holds the terminal. For example, it may be determined that the user holds the terminal if it is detected that the terminal has a grip, or it may be determined that the user does not hold the terminal. In a specific implementation, whether the terminal has grip strength is detected according to a pressure sensor built in the terminal. That is to say, after it is detected that the user holds the terminal, the terminal is triggered to adjust the volume of the terminal according to the relative position, and the time for adjusting the volume is accurately positioned to the time when it is detected that the user holds the terminal. In this example, considering that the user is more likely to hold the terminal to change the position of the terminal after holding the terminal, the relative position of the terminal and the human ear may change more frequently, and the distance between the terminal and the human ear may change faster. Under the condition, the volume of the terminal is adjusted according to the relative position of the terminal and the user, the relative position change of the terminal and the human ear is favorably adapted, the volume is dynamically adjusted, the more reasonable adjustment of the volume of the terminal is favorably realized, and the volume adjustment is more intelligent.
The above examples in the present embodiment are only for convenience of understanding, and do not limit the technical aspects of the present invention.
Compared with the prior art, the embodiment acquires the density information of each position in the preset range determined based on the position of the terminal, and determines the human body contour of the user corresponding to the terminal according to the density information. Because the density information between the object and the human body usually has difference, the density information at each position can reflect whether each position is the human body or other objects except the human body to a certain extent, and therefore, according to the density information at each position, the human body contour of the user corresponding to the terminal can be reasonably determined. The method comprises the steps of determining the relative position of a terminal and a user according to a human body contour, adjusting the volume of the terminal according to the relative position, wherein the relative position of the terminal and the user can reflect the distance between the terminal and the user to a certain extent, so that the distance between the terminal and the user can be considered according to the relative position of the terminal and the user, the volume of the terminal can be adjusted reasonably, and the method is suitable for the comfort level of the user which can accept the volume currently.
A second embodiment of the present invention relates to a volume adjustment method. The following describes the implementation details of the volume adjustment method of the present embodiment in detail, and the following is only provided for the convenience of understanding and is not necessary for implementing the present embodiment.
A flowchart of the volume adjustment method according to the present embodiment is shown in fig. 3, and includes:
step 201: and obtaining the density information of each position in the preset range.
Step 201 is substantially the same as step 101 in the first embodiment, and is not described herein again to avoid repetition.
Step 202: one position is selected among the positions as a reference position, and the other positions are taken as referenced positions.
That is, one point may be selected as a reference point (may also be referred to as a reference point) among all points within a preset range, and points other than the reference point may be taken as referenced points.
In one example, referring to fig. 2, the position of the center of the sphere within the preset range, i.e., within the sphere range, may be used as the reference position, and the positions other than the center of the sphere within the sphere range may be used as the referenced positions. In the present embodiment, the position of the center of the sphere is taken as an example only, and the specific implementation is not limited to this.
Step 203: based on the density information, density difference information between the reference position and each of the referenced positions is determined.
Specifically, according to the density information of each position in the preset range, the density difference information between the reference position and each referenced position is determined, that is, the difference between the density information of the reference position and the density information of each referenced position is obtained, so as to obtain the density difference information between the reference position and each referenced position. That is, for each referenced position, density difference information between the referenced position and the referenced position is corresponded.
Step 204: and determining the human body contour of the user corresponding to the terminal according to the density difference information.
In one example, referring to fig. 4, the point where the center of the sphere is located is used as the reference position, and the density difference information of each referenced position and the reference position is respectively obtained as +1, +0, +2, -1 in the figure; wherein, +1 represents that the density size difference between the reference position and the referenced position is + 1; +0 indicates that the difference of the density of the reference position and the referenced position is 0, namely the density of the reference position and the referenced position is the same; +2 indicates that the density size difference between the reference position and the referenced position is + 2. And depicting the positions with the same density difference information into an edge wire frame diagram, and then taking the edge wire frame diagram approximate to the human body as the human body outline of the user corresponding to the terminal. For example, referring to fig. 4, the edge line diagram drawn at each position with density difference information of +1 approximates to the human body, and therefore, the line frame diagram drawn at each position with density difference information of +1 can be used as the human body contour of the user corresponding to the terminal.
In specific implementation, a preset clustering algorithm can be adopted, and the human body contour of the user corresponding to the terminal is determined according to the density difference information, so that the accuracy of the determined human body contour is improved. The preset clustering algorithm can be selected according to actual needs, such as a K-means clustering algorithm, namely a K-means clustering algorithm.
Step 205: and determining the relative position of the terminal and the user according to the human body outline.
Step 206: and adjusting the volume of the terminal according to the relative position.
Step 205 to step 206 are substantially the same as step 103 to step 104 in the first embodiment, and are not described herein again to avoid repetition.
The above examples in the present embodiment are only for convenience of understanding, and do not limit the technical aspects of the present invention.
Compared with the prior art, in the embodiment, when the human body contour of the user corresponding to the terminal is determined, one position is selected from each position as the reference position, other positions are used as the referenced positions, the density difference information between the reference position and each referenced position is determined according to the density information, and the human body contour of the user corresponding to the terminal is determined according to the density difference information. In consideration of the fact that actually detected density information at each position may have errors, in the embodiment, the human body contour of the user corresponding to the terminal is determined according to the density difference information, which is beneficial to improving the accuracy of the determined human body contour.
A third embodiment of the present invention relates to a sound volume adjustment method. The application scenario of the embodiment may be to adjust the volume of the ring tone played by the terminal. The following describes the implementation details of the volume adjustment method of the present embodiment in detail, and the following is only provided for the convenience of understanding and is not necessary for implementing the present embodiment.
As shown in fig. 5, a flow chart of the volume adjustment method according to the present embodiment includes:
step 301: and after the terminal is determined to be in the calling state or the called state, acquiring density information of each position in a preset range.
In one example, when it is determined that the terminal is in a calling state or a called state, a preset density detector in the terminal may be turned on, so as to start to acquire density information at each position within a preset range. The implementation manner of obtaining the density information at each position in the preset range may refer to step 101 in the first embodiment, and in order to avoid repetition, this embodiment is not specifically limited to this.
In one example, before obtaining the density information at each position within the preset range after determining that the terminal is in the calling state or the called state, the method further includes: and determining that the terminal is not externally connected with a playback device. Wherein, external playback equipment can be: earphones, sound boxes, televisions and the like.
In one example, for a called terminal, when a calling terminal calls the called terminal, a color ring platform may obtain number information corresponding to the called terminal. Then, the polyphonic ringtone platform can send an external equipment viewing request to the called terminal according to the number information corresponding to the called terminal. The called terminal feeds back a feedback result of whether the called terminal is externally connected with the playback device to the polyphonic ringtone platform, and if the polyphonic ringtone platform determines that the called terminal is not externally connected with the playback device, the called terminal can be sent with an instruction to indicate the called terminal to start to acquire density information at each position in a preset range determined based on the position of the called terminal.
In another example, for the calling terminal, when the calling terminal calls the called terminal, if it is determined that the calling terminal is not externally connected with a sound reproduction device, the calling terminal may start to acquire density information at each position within a preset range determined based on the position of the calling terminal.
In the specific implementation, if it is determined that a terminal (a calling terminal or a called terminal) is externally connected with a playback device, the volume of the ring played by the terminal can be directly adjusted to the volume comfortable for human ears without acquiring density information at each position within a preset range; wherein, the comfortable volume of people's ear can set up according to actual need, and different users can predetermine the comfortable volume of different people's ears according to individual comfort level. For example, however, the specific value of the sound volume comfortable for the human ear is not particularly limited in the present embodiment. For example, if the called terminal is externally connected with a bluetooth headset, the ring volume of the terminal can be automatically adjusted to a volume comfortable for human ears when the terminal is called, so that the user is prevented from being scared by too large ring volume, and the hearing experience of the user is improved.
Step 302: and determining the human body contour of the user corresponding to the terminal according to the density information.
Step 303: and determining the relative position of the terminal and the user according to the human body outline.
Step 304: and adjusting the volume of the ring tone played by the terminal according to the relative position.
Step 304 is substantially the same as step 104 in the first embodiment, except that the volume of the ring tone played by the terminal is mainly adjusted in this embodiment. The ring played by the terminal may be a ring played by the called terminal during the process of calling the called terminal by the calling terminal, or a ring played by the calling terminal.
In an example, the volume adjusting method in this embodiment is applied to an electronic device, where the electronic device is a terminal, and the terminal may send the relative position to a color ring platform, so that the color ring platform determines the adjusted ring volume and sends a ring played with the adjusted ring volume to the terminal, and then the terminal plays the ring sent by the color ring platform.
To facilitate understanding of the present embodiment, the following scenarios are exemplified by adjusting the volume of the terminal ring, where the terminal is exemplified by a mobile phone:
scene one: the user takes the phone out of the pocket. When the mobile phone is in a pocket, the mobile phone is far away from the head of a user (the vertical spacing distance is large), so that the volume of the ring can be adjusted to be about 80% of the maximum volume. The user may take the phone out (e.g., detect a holding force value) and adjust the volume of the ring tone from about 80% of the maximum volume to about 50% of the maximum volume. In a specific implementation, the vertical distance between the mobile phone and the head of the user is gradually reduced, and the volume of the ring tone can be gradually adjusted from about 80% of the maximum volume to about 50% of the maximum volume.
Scene two: the user holds the mobile phone by hand and swings left and right in the air. For example, when the mobile phone detects a holding force value and detects that the vertical spacing distance between the mobile phone and the head of the user fluctuates within a small range, it can be determined that the user holds the mobile phone by hand and swings left and right in the air. In this process, the volume of the ring tone may be kept unchanged, for example, the volume of the ring tone may be adjusted to about 70% of the maximum volume and kept unchanged. Alternatively, the volume is turned up or down in a small range with 70% of the maximum volume as a reference.
Scene three: the user places the phone into the pocket from the head position. For example, the vertical distance between the mobile phone and the head of the user gradually increases, and the volume of the ring tone can be gradually adjusted from about 50% of the maximum volume to about 80% of the maximum volume. In specific implementation, the peak value of the adjusted volume may be preset to be 85% of the maximum volume, so as to avoid damage to the mobile phone due to too large volume of the mobile phone.
The above examples in the present embodiment are only for convenience of understanding, and do not limit the technical aspects of the present invention.
