Specific embodiments of the present disclosure have been shown by way of the above drawings and will be described in more detail below. These drawings and the written description are not intended to limit the scope of the disclosed concepts in any way, but rather to illustrate the disclosed concepts to those skilled in the art by reference to specific embodiments.
Detailed Description
Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure as detailed in the accompanying claims.
The embodiment of the disclosure provides a method for recommending songs, which can be realized by a server and can be realized by terminal cooperation. As shown in fig. 1, a system for recommending songs according to an embodiment of the present disclosure may include a server and a terminal.
The terminal can be provided with a music playing application program, and a user can start the music playing application program in the terminal and play songs which the user wants to listen to through the music playing application program. The user can input the name of the song which the user wants to listen to in the music playing application program, or can trigger the music playing application program to recommend some songs through preset gesture operation, for example, the user can draw an arc on a touch screen of the terminal with a finger, the terminal can detect gesture track information input by the user, and trigger recommendation of some songs to the user.
An exemplary embodiment of the present disclosure provides a method for recommending songs, as shown in fig. 2, a process flow of the method may include the following steps:
step S201, a song recommendation request sent by the terminal is received.
The song recommendation request carries gesture track information input by a user in a touch screen of the terminal.
In implementation, when a user performs a sliding operation on a touch screen of the terminal with a finger, the terminal may detect a sliding signal and acquire gesture track information input by the user. The gesture track information can be position coordinates of a touch point, in a preset coordinate system, of a finger and touch screen contact acquired according to a preset sampling frequency and a corresponding acquisition time point, and the preset coordinate system can be a coordinate system established by taking a touch screen center point or other preset points in the touch screen as an origin.
After the terminal acquires gesture track information input by the user, a song recommendation request can be generated, the song recommendation request carrying the gesture track information is sent to the server, and the server can receive the song recommendation request sent by the terminal.
Step S202, determining target beat information based on gesture track information.
In an implementation, the server may determine a song to be recommended based on the gesture track information, and send the determined song to be recommended to the terminal. In the above process, the server may first determine the type of the song to be recommended, such as target beat information of the song to be recommended, based on the gesture track information. If the user is currently playing a song W through the terminal, the user wants to hear some songs having beats faster or slower than the song W, and the music playing application program can be triggered to recommend some such songs through a preset gesture operation. Different gesture track information corresponds to different beat information, so the server can determine target beat information of songs to be recommended based on the gesture track information sent by the terminal. The process of determining the target beat information based on the gesture track information will be described in detail later herein, and will not be described in detail herein.
In step S203, in a preset song library, a song to be recommended, in which the beat information and the target beat information are matched, is determined.
In implementation, the server may pre-establish a song library, store a large number of released songs in the song library, and store song related information corresponding to each released song in the song library, where the song related information includes a name of the song, singer information, release time, beat information, and the like. After the server determines the target beat information of the song to be recommended, the server can search the song to be recommended, of which the beat information is matched with the target beat information, in a preset song library based on the related information of the song.
Step S204, the songs to be recommended are sent to the terminal.
In an implementation, after the server determines the song to be recommended, the song to be recommended may be sent to the terminal. The song to be recommended may include a name of the song to be recommended, introduction information, audio data, and the like. The server may send the name and introduction information of the song to be recommended to the terminal, and when the user selects to play the target song to be recommended after looking up the name and introduction information of the song to be recommended, the server sends the audio data of the target song to be recommended to the terminal. Or the server can also directly send the name, the introduction information and the audio data of the song to be recommended to the terminal, and when the user selects to play the target song to be recommended after looking up the name and the introduction information of the song to be recommended, the audio data corresponding to the target song to be recommended which is received locally by the terminal is directly played.
The process of determining target beat information based on gesture trajectory information will be described in detail below.
Alternatively, when the user wants to hear some songs having a particular tempo, the user may draw an arc on the touch screen through a sliding operation, and the gesture track information may be arc track information. Based on the gesture track information, the step of determining target beat information may include: determining the length of the arc track and the radius of the arc track relative to a preset point in the touch screen based on gesture track information; determining the perimeter of a circle taking the preset point as the center of the circle based on the radius of the arc track relative to the preset point; and determining target beat information based on the circumference of the circle and the length of the circular arc track.
In an implementation, the gesture track information may include position coordinates of touch points, in a preset coordinate system, of a finger and a touch screen, where the position coordinates are acquired according to a preset sampling frequency, and the server may calculate a length of the arc track based on the position coordinates of each touch point, and may also calculate a radius of the arc track relative to a preset point in the touch screen. Then, the server may determine a perimeter of a circle centered on the preset point, which may be a center point of the touch screen, based on a radius of the circular arc track with respect to the preset point. Finally, the server may determine whether the circle drawn by the user through the sliding operation on the touch screen is enough for one circle based on the circumference of the circle and the track length of the circle, and determine the target beat information based on the determination result.
In the embodiment of the present disclosure, in two cases, when the circle of the arc drawn by the user through the sliding operation on the touch screen is less than one circle, the target beat information may be determined by the first mode, and when the circle of the arc drawn by the user through the sliding operation on the touch screen is more than one circle, the target beat information may be determined by the second mode.
In practical application, when the terminal detects the sliding operation of the user, as shown in fig. 3, a preset circular line sliding rail and a key on a circular line may be displayed, the user may drag the key to move around the circular line, the center of the circular line is the center point of the touch screen, the radius of the circular line is fixed, the radius of the circular line may be used as the radius of the circular arc track, and the server may calculate the circumference of the circle based on the radius of the circular line.
Or if the preset circle line and the key on the circle line are not displayed in the terminal, the user can freely perform sliding operation, the circular arc drawn by the user may not be a standard circle, after the gesture track information is acquired, the position coordinates of the intersection point of the gesture track information and two straight lines passing through the preset point in the touch screen and perpendicular to each other can be determined, the average value of the distances between each intersection point and the preset point is calculated, the average value can be used as the radius of the approximate circular arc track relative to the preset point, and the server can calculate the circumference of a circle taking the preset point as the center of a circle based on the radius of the circular arc track relative to the preset point.
Optionally, when the circle of the arc drawn by the user through the sliding operation on the touch screen is less than one circle, the target beat information may be determined through the first mode, and when the circle of the arc drawn by the user through the sliding operation on the touch screen is more than one circle, the specific implementation manner of determining the target beat information through the second mode is as follows: the song recommendation request also carries the current beat information of the currently played song in the terminal and the sliding time length corresponding to the gesture track information, and if the arc track length is smaller than the circumference of the circle, the target beat information is determined based on the sliding direction of the gesture track information and the current beat information of the currently played song; if the length of the circular arc track is greater than or equal to the circumference of the circle, determining a sliding linear speed based on the length of the circular arc track and the sliding time length corresponding to the gesture track information, and determining target beat information based on the sliding linear speed.
In implementation, if it is determined that the length of the arc track is smaller than the circumference of the circle, the arc marked by the user through the sliding operation is indicated to be less than one circle, and then the target beat information can be determined based on the sliding direction of the gesture track information and the current beat information of the currently played song. If the length of the arc track is determined to be greater than or equal to the circumference of the circle, the arc track indicates that the arc drawn by the user through the sliding operation is enough for one circle, then the sliding linear speed can be determined based on the length of the arc track and the sliding time length corresponding to the gesture track information, and the target beat information is determined based on the sliding linear speed.
In addition to the above manner, it may be determined in other manners whether the circle of the arc drawn by the user through the sliding operation on the touch screen is enough, for example, an initial position of the sliding operation may be obtained, if a continuous sliding signal is detected and the sliding signal ends at the initial position, or the initial position ends, it indicates that the circle of the arc drawn by the user through the sliding operation on the touch screen is enough, or it indicates that the circle of the arc drawn by the user through the sliding operation on the touch screen is less than one.
(1) For the case that the circle of the arc drawn by the user through the sliding operation on the touch screen is less than one circle, the gesture track information can be the position coordinates of the finger acquired according to the preset sampling frequency and the touch point contacted by the touch screen in the preset coordinate system and the corresponding acquisition time point, and the server can determine the sliding direction of the corresponding arc track based on the gesture track information and can comprise the clockwise direction or the anticlockwise direction. The song recommendation request may further carry current beat information of the song currently played in the terminal, and then the server may determine target beat information based on the sliding direction of the circular arc track and the current beat information of the song currently played.
Optionally, the step of determining the target beat information based on the sliding direction of the gesture track information and the current beat information of the currently played song may include: if the sliding direction corresponding to the gesture track information is clockwise, determining beat information larger than the current beat information of the currently played song as target beat information; and if the sliding direction corresponding to the gesture track information is in the anticlockwise direction, determining beat information smaller than the current beat information of the currently played song as target beat information.
In the implementation, if the sliding direction corresponding to the gesture track information is clockwise, the server may determine that the beat information of the current beat information larger than the currently played song is the target beat information, and if the sliding direction corresponding to the gesture track information is counterclockwise, the server may determine that the beat information of the current beat information smaller than the currently played song is the target beat information.
The server may further obtain a song currently played in the terminal, determine a target type of the song currently played in the terminal, determine candidate songs belonging to the target type except the song currently played in the song library, and determine a song to be recommended whose beat information is greater than the current beat information of the song currently played in the candidate songs. Alternatively, a song to be recommended whose tempo information is smaller than the current tempo information of the currently played song may be determined among the candidate songs.
Alternatively, an initial position and an end position of the slide operation may also be acquired, a slide angle may be calculated based on the initial position and the end position, and the target beat information may be determined based on the slide angle.
In practice, the larger the sliding angle, the larger the difference between the target tempo information and the current tempo information of the currently played song. In practical application, an initial position and an end position of a sliding operation can be obtained, a first distance between the initial position and a preset point in the touch screen and a second distance between the end position and the preset point are calculated respectively, a distance average value of the first distance and the second distance is calculated, a third distance between the initial position and the end position is determined, and the distance average value and the third distance are solved through a cosine theorem to obtain a sliding angle. The difference between the target beat information and the current beat information of the currently played song may be determined based on the sliding angle, and the target beat information may be determined based on the current beat information of the currently played song and the determined difference.
And when the sliding direction corresponding to the gesture track information is clockwise, determining the sum value obtained by adding the determined difference value to the current beat information of the currently played song as target beat information. And when the sliding direction corresponding to the gesture track information is in the anticlockwise direction, determining a target difference value obtained by subtracting the determined difference value from the current beat information of the currently played song as target beat information.
(2) For the case that the arc drawn by the user through the sliding operation is enough for one circle on the touch screen, the server can also determine the sliding time length corresponding to the gesture track information, the sliding linear speed is obtained by dividing the sliding time length by the arc track length, and the target beat information is determined based on the sliding linear speed. The target beat information is larger as the sliding linear velocity is larger.
Optionally, if the arc track length is greater than or equal to the circumference of the circle, the method provided by the embodiment of the disclosure may further include: determining the number of sliding turns based on the length of the arc track and the circumference of the circle; determining a target number of songs to be recommended based on the number of sliding turns; in the preset song library, the step of determining the song to be recommended, in which the beat information and the target beat information are matched, may include: and determining songs to be recommended, of which the number is the target number, in a preset song library, wherein the beat information is matched with the target beat information.
In practice, the number of turns n of the slide may be determined as the target number of songs to be recommended by dividing the length of the circular arc track by the circumference of the circle. Then, n songs to be recommended, of which the beat information and the target beat information are matched, can be determined in a preset song library. At this time, the slip linear velocity may also be calculated by equation 1:
Wherein v is the sliding linear speed, n is the number of sliding turns, t is the sliding time length, and r is the radius of the arc track relative to a preset point in the touch screen.
Alternatively, after the sliding linear velocity is determined, if the sliding linear velocity is less than a first preset velocity threshold A1 (e.g., 12 cm/s), a song whose tempo information is less than a first tempo threshold (e.g., 65 bpm) is determined as a song to be recommended. If the sliding linear velocity is greater than the first preset velocity threshold value A1 and less than the second preset velocity threshold value A2 (such as 24 cm/s), determining the song with beat information greater than the first beat threshold value and less than the second beat threshold value (such as 100 bpm) as the song to be recommended. And if the sliding linear velocity is larger than a second preset velocity threshold value A2, determining the song with the beat information larger than the second beat threshold value as the song to be recommended. The song to be recommended may also be a song of which the type and the song currently played by the terminal belong to the same type.
In addition, alternatively, after the sliding linear velocity is determined, the song to be recommended may be determined based on the current tempo information of the song currently played by the terminal and the sliding linear velocity. And if the sliding linear velocity is smaller than or equal to a third preset velocity threshold value A3 (such as 15 cm/s), determining the song with the beat information smaller than the current beat information of the song currently played by the terminal as the song to be recommended. And if the sliding linear speed is greater than a third preset speed threshold A3, determining the song with the beat information greater than the current beat information of the song currently played by the terminal as the song to be recommended.
Optionally, the step of determining the target beat information based on the sliding linear velocity may include: determining the sliding time length corresponding to each sliding ring respectively; determining sliding linear speeds corresponding to the sliding rings respectively based on the circumferences of the circles and the sliding time lengths corresponding to the sliding rings respectively; determining target beat information corresponding to each sliding ring based on the sliding linear speed corresponding to each sliding ring; in the preset song library, the step of determining that the beat information is matched with the target beat information and the number of the songs to be recommended is the target number may include: and determining target numbers of songs to be recommended, of which the beat information is matched with the target beat information corresponding to each sliding ring respectively, in a preset song library.
In implementation, an average sliding linear velocity of n circles of sliding can be calculated, target beat information is determined based on the average sliding linear velocity, and n songs to be recommended are uniformly selected according to the target beat information. Alternatively, a corresponding target beat information may be determined for each song to be recommended, where different songs to be recommended have different target beat information.
The sliding time length corresponding to each sliding ring can be determined based on gesture track information, the circumference of the circle is divided by the sliding time length corresponding to each sliding ring to obtain the sliding linear speed corresponding to each sliding ring, and the target beat information corresponding to each sliding ring is determined based on the sliding linear speed corresponding to each sliding ring. The target beat information is larger as the sliding linear velocity is larger. And finally, determining n songs to be recommended, of which the beat information is matched with the target beat information corresponding to each sliding ring, in a preset song library.
For example, the user slides for 4 circles altogether, and the calculation determines that the sliding linear velocity of the first circle is 10cm/s, the sliding linear velocity of the second circle is 15cm/s, the sliding linear velocity of the third circle is 20cm/s, and the sliding linear velocity of the fourth circle is 8cm/s. The target tempo information of the first to fourth songs to be recommended may be determined to be 50bpm, 65bpm, 84bpm,45bpm in order based on the sliding linear velocities respectively corresponding to the sliding rings.
Since the user is not necessarily able to complete one circle at the end when sliding the multi-circle arc trajectory, the number of sliding circles may be determined in the following manner. Optionally, the step of determining the number of sliding turns based on the arc track length and the circumference of the circle may include: if the quotient obtained by dividing the length of the circular arc track by the circumference of the circle is an integer, determining the quotient as the number of sliding turns; if the quotient obtained by dividing the length of the circular arc track by the circumference of the circle is not an integer, determining the arc distance between the track end position and the track start position in the sliding direction in the gesture track information, if the arc distance is smaller than or equal to a preset threshold value, determining the integer part of the quotient by adding 1 as the number of sliding turns, and if the arc distance is larger than the preset threshold value, determining the integer part of the quotient as the number of sliding turns.
In practice, for the case where the user can drag the preset button to move around the preset circle line, when the starting point position and the ending point position are not coincident, i.e. when the quotient of the length of the circular arc track divided by the circumference of the circle is not an integer, the distance from the ending point position to the starting point position along the sliding direction or the arc length therebetween can be determined, if the distance or the arc length is smaller than or equal to the preset threshold (e.g.) When the last incomplete sliding ring is calculated according to a complete sliding ring, the integral part of the quotient can be added with 1 to obtain the valueThe number of sliding turns is determined. If the distance or the arc length is greater than the preset threshold, the last incomplete slip ring is not counted as a complete slip ring, and then the integer part of the quotient can be determined as the slip number.
For the case that the user can freely slide, the arc drawn by the user may not be a standard circle, as shown in fig. 4, the radius of the approximated arc track relative to the preset point in the touch screen may be calculated based on the gesture track information, then the arc distance from the end position to the start position along the sliding direction may be determined, if the arc distance is less than or equal to the preset threshold (e.g. ) The last incomplete slip ring can then be calculated as a complete slip ring, and then the value obtained by adding 1 to the integer part of the quotient can be determined as the slip number. If the arc distance is greater than the preset threshold, the last incomplete slip ring is not calculated according to a complete slip ring, and then the integer part of the quotient can be determined as the slip number.
