For example, shooting games, archery games and / or other similar action games are popular among game players. In such games, players control guns and other targets through the game interface, compete with other players, and simulate various competition experiences such as military competitions. During the game, players can obtain visual, auditory and tactile feedback, which ensures the experience in the game. The player's tactile sense is mainly provided by motor vibration. The motor usually vibrates at the time when vibration may occur, such as when firing a bullet, to provide players with a more realistic gaming experience.

[0003] In this type of game, traditional motor control solutions often determine parameters such as vibration timing based on the characteristics of audio data.

[0040] The technical solutions in the embodiments of the present application are clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application. In the absence of conflict, the following embodiments and their technical features can be combined with each other.

[0041] The first aspect of the present application provides a motor driving method, referring to Figure 1 As shown, the motor driving method includes:

[0042] S110, obtaining the current audio of the current game, and obtaining the relative frame count of the current audio; the relative frame count is used to represent the time count between the current vibration event and the previous vibration event.

[0043] The current audio can be obtained from an audio storage area such as an audio buffer pool of a game that requires a motor to be driven in the electronic device; the game that requires a motor to be driven may include at least one type of game such as a shooting game and / or a bow and arrow game. The audio storage area can be used to buffer the audio data generated by the application layer for the current game.

[0044] The relative frame count can describe the time count between the current vibration event and the last vibration event, so as to characterize the duration of each vibration event by using the corresponding counting rule, and is used to control the shortest time interval between each vibration event, so that the subsequent vibration control process is based on the relative frame count, which can avoid the occurrence of states such as continuous vibration for multiple events, and can improve the uniformity and stability of vibration for each event. The above steps can set the initial value of the relative frame count (such as a smaller value such as 0) at the start time of each vibration event, and then update the relative frame count according to a certain update rule to realize the counting of the duration of each vibration event, so that the relative frame count can characterize the shortest time interval required by some vibration events. The above update rule can include increasing the relative frame count by several counting units every certain time; or increasing the relative frame count by several counting units after processing a frame of data of the current audio, etc.; in this way, the relative frame count can be cleared to 0 after a vibration event ends, and recounted according to the update rule in the next vibration event, and the next vibration is performed when the relative frame count meets the conditions, so as to accurately control the shortest time interval between each vibration event. The duration of the interval in the update rule may be 20 ms (milliseconds) or other time.

[0045] S120, obtaining a target identifier and a current trigger factor number of the current game interface; the target identifier represents the sign information of the control target in the current game interface; the current trigger factor number represents the number of factors that trigger vibration included in the current game interface.

[0046] The current game may be a game that requires a motor to be driven in an electronic device, and may be a shooting game, an archery game, or other similar action games. The above target identifier and the current trigger factor number match the type of the current game. For example, if the current game is a shooting game, the target identifier may be the gun identifier information such as the type of gun currently being controlled, and the current trigger factor number may be the number of fired bullets corresponding to the current game interface; if the current game is an archery game, the target identifier may be the identifier information such as the type of bow and arrow currently being controlled, and the current trigger factor number may be the number of fired arrows corresponding to the current game interface, and so on.

[0047] After starting the current game, the electronic device can take screenshots of its game interface at a certain frequency to obtain each game interface, identify the control target mark information and vibration trigger factor number of each game interface, and write the identified control target mark information and vibration trigger factor number into the corresponding node and other data recording units, so that when the control target mark information and vibration trigger factor number data need to be obtained, they can be directly read from the above data recording unit to ensure the reading efficiency and the accuracy of the obtained results. The frequency of obtaining the game interface can be matched with the progress of the audio processing. For example, when the interval in the update rule is 20ms, the audio processing is performed approximately every 20ms, that is, the control target mark information and vibration trigger factor will be read every 20ms, and the screenshot can be performed once every 85ms. Here, the audio processing is performed faster than the image screenshot to ensure that the control target information and vibration trigger factor are not missed.

[0048] S130, determining the number of vibrations according to the current number of trigger factors; the number of vibrations is used to record the remaining number of motor vibrations in the current game.

[0049] This embodiment can set the initial value of the vibration number of the current game based on factors such as the range of vibration trigger factors that may occur in the current game, the time interval between each vibration trigger factor, and / or the update rule of the vibration number, so as to update each vibration number according to the current trigger factor number for the initial value, so that the vibration number can accurately record the remaining motor vibration number of the current game at each time point. In one example, the above-mentioned vibration number determination rule matches the change characteristics of the current trigger factor number. For example, if the current trigger factor number increases and / or decreases relative to the previous trigger factor number, the vibration number can be updated accordingly. In another example, the above-mentioned vibration number determination rule is also associated with whether the motor is driven to vibrate. For example, after the motor is driven to perform a vibration, the vibration number can be reduced by several counting units so that the vibration number matches the game process.

[0050] S140: If the relative frame count and the vibration times meet the driving conditions, the motor is driven to vibrate according to the vibration waveform corresponding to the target identifier.

[0051] The above relative frame count can represent the interval time between the current vibration event and the end time of the last vibration event. When the interval time is short, the vibration generated is very likely to affect the vibration stability; the above vibration count represents the remaining motor vibration number of the current game. If it exceeds the range of the remaining motor vibration number of the current game, the vibration generated is likely to be invalid vibration for the current game; therefore, the above steps can judge the relative frame count and vibration number, identify the relative frame count and vibration number that meet the driving conditions, and when the relative frame count and vibration number meet the driving conditions, the motor vibration is driven according to the vibration waveform corresponding to the target identifier to ensure the effectiveness and stability of the motor vibration. The vibration waveform includes waveforms pre-configured for various control targets in various games (such as waveforms configured for various gun types in shooting games and / or waveforms configured for various bow types in bow and arrow games, etc.), which are used to limit the vibration parameters such as vibration frequency and vibration amplitude corresponding to the corresponding control target, so that the vibration parameters are more matched with the control target, which can improve the accuracy and diversity of the corresponding vibration, and further enhance the user experience brought by the motor vibration.

[0052] Furthermore, the above motor driving method may also include: playing the current audio to synchronize the motor driving process, the interface display process and the audio playing process, so as to further ensure the gaming effect.

[0053] Furthermore, the above-mentioned motor driving method also includes: if the relative frame count and the vibration number do not meet the driving conditions, the relative frame count is increased by a second counting unit, and the execution step S110 is returned to obtain the latest relative frame count of the current audio, and the vibration number is updated, and then the motor vibration is continued to be controlled according to the relative frame count and the vibration number to ensure the orderliness and stability of the motor vibration.

[0054] This embodiment identifies whether the motor driving conditions are met based on the relative frame count determined by the current audio and the number of vibrations determined by the current trigger factor number, so that the motor driving conditions are determined based on the time interval between the current vibration event and the previous vibration event, which can improve the vibration stability and avoid the occurrence of conditions such as uneven vibration. The above-mentioned motor driving conditions are also determined based on the remaining number of motor vibrations in the current game, and whether vibration is needed can be determined in turn according to the remaining number of motor vibrations. On the basis of ensuring the effectiveness of vibration, it can also prevent the occurrence of missed vibrations and / or false vibrations. It can be seen that this embodiment can effectively drive the motor vibration during the game, prevent the occurrence of missed vibrations, false vibrations and / or uneven vibrations that affect the vibration effect, improve the vibration effect, and thus improve the user experience brought by the game product.

[0055] In one embodiment, the motor driving method further includes:

[0056] If the number of vibrations is greater than the driving threshold and the relative frame count is greater than the time interval threshold, it is determined that the relative frame count and the number of vibrations meet the driving conditions, otherwise it is determined that the relative frame count and the number of vibrations do not meet the driving conditions; the driving threshold is used to limit whether there is currently an available number of vibrations for the current game; the time interval threshold represents the minimum time interval between two adjacent vibration trigger factors.

[0057] The above-mentioned driving threshold can be set to a smaller value such as 0. The number of vibrations greater than the driving threshold indicates that the vibration event generated subsequently is a valid vibration of the current game, and it can be further determined whether the subsequent vibration needs to be continued. The number of vibrations less than or equal to the driving threshold indicates that the vibration event generated subsequently is very likely to be an invalid vibration relative to the current game. At this time, the motor needs to be controlled not to vibrate to avoid invalid vibrations affecting the vibration effect. The time interval threshold represents the minimum time interval between two adjacent vibration triggering factors, such as the minimum time interval between adjacent arrows in bow and arrow games or the minimum time interval between consecutive adjacent bullets in shooting games, etc. Here, shooting games are taken as an example to further illustrate that the vibration to be generated matches the operation of firing a bullet, and one vibration is generated once a bullet is fired. The relative frame count is greater than the time interval threshold, indicating that the two vibration events associated with the relative frame count correspond to two bullet firing events. When the relative frame count is greater than the time interval threshold, the corresponding vibration is generated, so that the vibration matches each bullet firing operation, which can improve the effectiveness of the vibration; the relative frame count is less than or equal to the time interval threshold, indicating that the shortest time interval between the corresponding vibration events is short, and it is very likely that multiple vibration events will occur continuously, resulting in uneven vibration.

[0058] In this embodiment, when the number of vibrations is greater than the driving threshold and the relative frame count is greater than the time interval threshold, it is determined that the relative frame count and the number of vibrations meet the driving conditions, so that each vibration driven according to the determination result can be more effective and more stable.

[0059] In one embodiment, after driving the motor to vibrate according to the vibration waveform corresponding to the target identifier, the motor driving method further includes:

[0060] The relative frame count is cleared to zero, and the vibration count is reduced by a first count unit to control the next vibration event of the current game.

[0061] The first counting unit can be set to 1 or other counting units. In this embodiment, the driving motor vibration indicates that the corresponding vibration event (such as the current vibration event) has ended, and the relative frame count needs to be cleared to enable the relative frame count to accurately represent the time interval between the new vibration event and the corresponding previous vibration event; after completing a motor vibration, the number of vibrations is subtracted by a first counting unit to match the number of vibrations with the game process, and the number of motor vibrations remaining in the current game can be prepared; in this way, based on the relative frame count and the number of vibrations, each motor vibration can be more accurately controlled to ensure the effectiveness and stability of each motor vibration event.

[0062] In one embodiment, determining the number of vibrations based on the current number of trigger factors includes: obtaining the current change in the number of trigger factors based on the current number of trigger factors, and updating the number of vibrations based on the change in the number of trigger factors, such as updating the number of vibrations to the sum of the number of vibrations and the change in the number of trigger factors, so that the number of vibrations matches the number of vibration trigger factors generated by the current game (such as the number of bullets fired, etc.).

[0063] This embodiment can set data including the last trigger factor number and the current trigger factor number, so as to update the current trigger factor number for the array, calculate the change in the trigger factor number, etc., and simplify the above-mentioned processing procedures. Specifically, if bulletbuff[0] is used to record the last trigger factor number, and bulletbuff[1] is used to record the current trigger factor number, in the process of updating the array, the current trigger factor number bullet is first obtained. If bullet≠bulletbuff[1], bulletbuff[0]=bulletbuff[1], bulletbuff[1]=bullet, so as to update each element in the array. At this time, the change in the trigger factor number is: bulletdiff=bulletbuff[0]-bulletbuff[1]. In an example, trig_num is used to represent the number of vibrations. If bulletdiff>0, trig_num=trig_num+bulletdiff is set to update the number of vibrations trig_num.

[0064] In one embodiment, obtaining the relative frame count of the current audio includes:

[0065] Splitting the current audio into multiple audio frame units that are continuous in time sequence;

[0066] When one frame of audio unit is processed, the relative frame number count is increased by a second counting unit.

[0067] The second counting unit can take a counting unit value such as 1. In this embodiment, the current audio can be framed with N audio data (such as audio sampling points) as a step size, and the audio units with less than N audio sampling points can be padded with 0 to obtain multiple frames of audio units that are continuous in time sequence, so that the audio data to be processed includes multiple frames of audio units, and each frame of audio unit includes N audio sampling points. The value of N can be an integer power of 2 such as 1024. In many cases, the time to process a frame of audio unit is certain (such as 20ms), so this embodiment can also increase the relative frame count by a second counting unit at regular intervals (the time required to process a frame of audio unit) to match the relative frame count with the processing progress of the current audio.

[0068] In one embodiment, obtaining the current audio of the current game includes:

[0069] After obtaining the read permission of the audio storage area of ​​each type of game, the current audio of the current game is read from the audio storage area; the audio storage area is used to buffer the audio data corresponding to the current game.

[0070] After various games are started, the application layer of the electronic device can generate corresponding audio data and buffer the audio data to the audio storage area for use by other modules. This embodiment first obtains the read permission of the audio storage area, and then directly reads the current audio of the current game from the audio storage area, which can ensure the smoothness, timeliness and integrity of the current audio reading process.

[0071] Specifically, after obtaining the read permission of the audio storage area, after reading the current audio of the current game from the audio storage area, volume compensation can also be performed on the current audio to compensate the read volume to the same level of volume.

[0072] Here, the volume of the audio data obtained from the audio storage area is compensated, and the audio data is normalized to the maximum volume or the same level of volume, which can improve the quality of subsequent processing of the audio data.

[0073] In one embodiment, before obtaining the target identifier of the current game interface and the current trigger factor number, the motor driving method further includes:

[0074] The game interface is obtained, the flag information of the control target and the vibration trigger factor number included in the game interface are parsed, and the flag information and the vibration trigger factor number are written into a designated node to read the target identifier and the current trigger factor number from the designated node.

[0075] The above-mentioned designated node can be set in the system kernel and other areas, and the latest flag information and vibration trigger factor number recorded by it are usually the target identifier and current trigger factor number of the current game interface. In this embodiment, the flag information and vibration trigger factor number of the control target included in the game interface are written into the designated node, so as to directly read the target identifier and current trigger factor number from the designated node, which can improve the reading efficiency of the target identifier and current trigger factor number.

[0076] In one embodiment, the games that require the driving of the motor may include at least one type of game such as shooting games and / or bow and arrow games, so as to stably and effectively drive the motor for each type of game, respectively, and enhance the tactile experience brought by each type of game. When the games include shooting games, the current game belongs to the shooting games; the control target includes the control of the gun, and the target identifier may be the current gun type; the factors that trigger the vibration include the bullets fired by the controlled gun, and the current number of trigger factors may be the current number of bullets. When the games include bow and arrow games, the current game belongs to the bow and arrow games; the control target includes the control of the bow and arrow, and the target identifier may be the current bow type; the factors that trigger the vibration include the arrows shot by the controlled bow and arrow, and the current number of trigger factors may be the number of arrows currently shot.

[0077] In one example, a shooting game is used as an example to illustrate the system framework corresponding to the motor driving method. In this example, the application layer (App layer), core class library (Native layer), hardware abstraction layer (Hal layer) and system kernel (Kernel layer, such as Linux kernel) of the shooting game system perform various functions related to audio data. The corresponding system framework diagram can be referred to Figure 2As shown, after starting the game, each layer of the system works separately. The application layer realizes sound effect control. At this time, the above-mentioned audio data is set for each game, wherein volume compensation can be realized through an interface, and the current volume level parameters obtained are passed to the algorithm of the hardware abstraction layer, so that the algorithm of the hardware abstraction layer performs volume compensation, which may specifically include: first, creating sound effects, enabling and releasing sound effects, where the system in which the motor vibrates precisely with shooting games is realized by sound effects; second, setting the game mode, the application layer obtains each game type by parsing the current application game package, and then sets the parameters of each game, for example, some algorithm libraries can support a whole set of games, such as shooting games and racing games, and different games can be configured with different parameters; third, volume compensation, the size of the audio data sent by the system at different volume levels is different, in order to realize the unification of volume data in the system in which the motor vibrates precisely with shooting games, the volume compensation coefficient is set according to the volume level of the current system to perform volume compensation, and unify the size and / or volume of each audio data and other parameters. The core class library is responsible for obtaining the function of sound effect service (audio data). The system loads the sound effect algorithm library of the motor that vibrates accurately with shooting games through AudioFlinger (audio policy executor) and AudioPolicyManager (audio policy manager) to enable the corresponding electronic equipment to obtain audio data. The hardware abstraction layer implements the motor driving algorithm. It can realize two functions. First, obtain the original audio data of the current game (current audio); second, execute the algorithm interface of the sound effect algorithm library of the motor that vibrates accurately with shooting games. This interface obtains the gun type and number of bullets information of the current game interface from the system kernel, determines whether to vibrate according to the changes in the gun type and number of bullets, and sends the vibration information containing the vibration (such as vibration waveform) to the system kernel. The above system kernel can control the relevant driver end to control the motor vibration through the operating chip according to the vibration information sent by the hardware abstraction layer.

[0078] Further, refer to Figure 2 As shown in the figure, the application layer, core class library and system kernel of the system where the shooting game is located perform various functions related to the game interface. Among them, the application layer implements image control, mainly realizing the function of starting or shutting down the image service and obtaining a screenshot of the current game interface. The core class library implements image processing services, mainly realizing the following three functions: first, parsing (TP parser parsing) the touch events received by the system kernel; second, taking screenshots based on the touch events; third, identifying the captured pictures, obtaining the gun type and number of bullets in the picture interface, and writing the gun type and number of bullets to the specified node of the system kernel layer. The system kernel mainly realizes the following two functions: one is to obtain the specified node issued by the system kernel, and the other is to report the touch event (TP event) to the core class library.

[0079] The above motor driving method obtains the relative frame count representing the time count between the current vibration event and the previous vibration event, and also obtains the target identifier of the current game interface and the current trigger factor number, determines the vibration number representing the remaining motor vibration number of the current game according to the current trigger factor number, and then judges whether the motor driving conditions are met based on the relative frame count and the vibration number, so that the judgment of the motor driving conditions is based on the time interval between the current vibration event and the previous vibration event, which can improve the vibration stability and avoid the occurrence of conditions such as uneven vibration and / or invalid vibration; the judgment of the above motor driving conditions is also based on the remaining motor vibration number representing the current game, and can judge whether vibration is needed according to the remaining motor vibration number in turn, and can prevent the occurrence of missed vibration and / or false vibration on the basis of ensuring the effectiveness of vibration; therefore, the above motor driving method can effectively drive the motor vibration during the game, prevent the occurrence of missed vibration, false vibration and / or uneven vibration and other conditions that affect the vibration effect, improve the vibration effect, and thus improve the user experience brought by the game product.

[0080] In a second aspect, the present application provides a motor drive system, such as Figure 3 As shown, the motor drive system includes:

[0081] The first acquisition module 110 is used to acquire the current audio of the current game and acquire the relative frame count of the current audio; the relative frame count is used to represent the time count between the current vibration event and the previous vibration event;
