Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of game terminal, and particularly relates to a noise reduction method of force feedback device, a game handle and a storage medium. BACKGROUND

[0002] The game handle is a common device used together with the game machine, and the game character can be controlled by operating the keys and the joystick. With the continuous development of the game handle, more and more game handles with more functions are provided for players, and the game handles with vibration function are not rare. During the game process, the vibration feeling brought to the player by the game handle provides the player with a sense of being in the scene.

[0003] The vibration feeling of the game handle is realized by controlling the vibration rod of the force feedback device arranged therein to reciprocate at a response frequency. However, the vibration rod is prone to collide with the adjacent structure below during the descending process, thereby bringing noise to the player while providing the vibration feeling to the player during the use of the game handle, and reducing the user experience. SUMMARY

[0004] The noise reduction method of the force feedback device, the game handle and the storage medium provided by the present application can reduce the noise generated when the vibration feeling is brought to the player during the use of the game handle.

The method can reduce the noise generated when the vibration feeling is brought to the player during the use of the game handle.

[0006] Further, the calculation of the first time for the vibration rod to complete the first motion comprises calculating the first time required for the vibration rod to complete the first motion based on the first position information and the second position information of the vibration rod, the driving strength of the driving mechanism and a correction coefficient.

[0007] Further, the first position information and the second position information of the vibration rod, the driving strength of the driving mechanism, and the correction coefficient are used to calculate a first time required for the vibration rod to complete the first movement, which includes calculating the first time based on the following formula:

[0008] t1=K / A*(P2+1–P1);

[0009] wherein t1 represents the first time required for the vibration rod to complete the first movement, P1 represents the first position information, P2 represents the second position information, A represents the driving strength of the driving mechanism, and K represents the correction coefficient applicable to the current.

[0010] Further, the second position in the second position information is a fixed position or a non-fixed position on the movement route of the vibration rod.

[0011] Further, if the second position is a non-fixed position on the movement route of the vibration rod, the actual position of the second position matches the level of the vibration event; wherein the vibration event includes multiple levels.

[0012] Further, after the first time elapses from the start of the driving of the vibration rod to the first movement, and after the vibration rod is controlled to stop the first movement, the method further includes calculating a second time required for the vibration rod to perform a second movement according to the driving frequency of the driving mechanism, and controlling the vibration rod to stop the second movement after the second time elapses from the start of the driving of the vibration rod to the second movement to avoid collision with the second structure.

[0013] Further, the calculation of the second time required for the vibration rod to perform the second movement according to the driving frequency of the driving mechanism includes calculating the second time based on the following formula:

[0014] t2=1 / (2*F)

[0015] wherein t2 represents the second time required for the vibration rod to perform the second movement, and F represents the driving frequency of the driving mechanism.

[0028] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are some embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0029] Figure 1 A gamepad schematic diagram is provided for an embodiment of the present application.

[0030] Referring to Figure 1 The gamepad 100 is a component of a common electronic game console, and controls a virtual game character by manipulating its keys, etc. A common gamepad 100 can include a cross key 101 (direction), ABXY keys 102 (action - different methods are used by hardware manufacturers, but the arrangement is generally the same), a joystick 103 (direction and viewing angle), a trigger key 104, and a HOME menu key 105, etc. The noise reduction method of the force feedback device provided in the present embodiment does not limit the type, number, and arrangement of the keys of the gamepad.

[0031] When playing a game, the gamepad 100 is connected to a terminal (such as a computer, a television, or a smart terminal, etc.), and the current scene information of the game is presented on the screen of the terminal. The player controls the keys on the gamepad to control the display of the game picture and the virtual character in the game.

[0032] When a corresponding scene in the game contains a vibration event, the gamepad 100 needs to vibrate to provide the player with a vibration sensation. The gamepad 100 can include a corresponding device with a vibration function. In an embodiment, the gamepad 100 can also be built-in with a force feedback device to vibrate when a vibration event occurs in the game to provide the player with a corresponding vibration sensation.

[0033] In an embodiment, one or more force feedback devices can be included in a gamepad. When a vibration event occurs in the game, the gamepad can vibrate through the one or more force feedback devices, and the player can perceive the game feedback information through the vibration sensation.

[0034] In a scenario where one force feedback device is provided in a gamepad, when a vibration event occurs in the game, the gamepad controls the one force feedback device to vibrate, and the player can perceive the game feedback information through the vibration sensation.

[0035] In a scenario where at least two force feedback devices are provided in a gamepad, the gamepad vibrates through the corresponding force feedback devices among the at least two force feedback devices, so that the player can perceive the game feedback information through the vibration sensation.

[0036] For example, two force feedback devices can be arranged on the two sides of the gamepad. After obtaining the coordinate system information of the screen displaying the game picture, the gamepad can obtain the coordinate information of the vibration event in the game relative to the screen during the game process, and then determine the position of the force feedback device that needs to be triggered to vibrate. Specifically, the vertical center line of the screen can be taken as the reference line, and the screen can be divided into left half screen and right half screen. If it is determined according to the obtained coordinate information of the vibration event in the game relative to the screen that the vibration event corresponding coordinates are distributed in the left half screen of the screen, the force feedback device on the left side of the gamepad is triggered to vibrate; if it is determined according to the obtained coordinate information of the vibration event in the game relative to the screen that the vibration event corresponding coordinates are distributed in the right half screen of the screen, the force feedback device on the right side of the gamepad is triggered to vibrate.

[0037] For example, four force feedback devices (force feedback device A, force feedback device B, force feedback device C, and force feedback device D) can be arranged on the four corners of the gamepad. After obtaining the coordinate system information of the screen displaying the game picture, the gamepad can obtain the coordinate information of the vibration event in the game relative to the screen during the game process, and then determine the position of the force feedback device that needs to be triggered to vibrate. Specifically, the vertical center line and the horizontal center line of the screen can be taken as the reference line, and the screen can be divided into four regions, i.e., the first region, the second region, the third region, and the fourth region. The force feedback device A corresponds to the first region of the screen, the force feedback device B corresponds to the second region of the screen, the force feedback device C corresponds to the third region of the screen, and the force feedback device D corresponds to the fourth region of the screen. According to the coordinate information of the vibration event in the game relative to the screen, it is determined that the vibration event corresponding coordinates are distributed in which region of the screen. For example, if the coordinate information of the vibration event in the game relative to the screen is distributed in the first region of the screen, the force feedback device A of the gamepad is triggered to vibrate. If the coordinate information of the vibration event in the game relative to the screen is distributed in the first region, the second region, the third region, and the fourth region, the force feedback device A, the force feedback device B, the force feedback device C, and the force feedback device D of the gamepad are all triggered to vibrate.

[0038] Figure 2 The structure diagram of the force feedback device provided for another embodiment of the application is shown.

[0039] Reference Figure 2As shown, the force feedback device may include a driving mechanism 201, a vibration rod 202, and a protective cap 203. The driving mechanism 201 may drive the vibration rod 201 to perform reciprocating motion at a set frequency, wherein one reciprocating motion may be driving the vibration rod 201 to perform a first motion from a first position (the position of the protective cap 203) to a second position (the return position). After the vibration rod 202 reaches the second position, the driving mechanism 201 drives the vibration rod 202 to perform a second motion to reset the vibration rod 202 to the first position. The first motion of the vibration rod 201 is toward the first structure, and the second motion of the vibration rod 201 is toward the second structure. In one embodiment, the first structure is Figure 2 The adjacent structures shown, the second structure is Figure 2 The protective cap 203.

[0040] In actual application, when the vibration rod 202 is in the reciprocating motion, specifically when the vibration rod 202 is in the first motion, the vibration rod 202 may collide with the Figure 2 An impact event occurs on the adjacent structure shown, that is, at the impact position 204. The impact sound generated by the impact event may cause continuous noise when vibration events frequently occur on the game controller 100, affecting the user's gaming experience.

[0041] To overcome the above problems, an embodiment of the present application provides a noise reduction method for a force feedback device. This method can reduce the probability of a collision event occurring on the vibration rod 202 by controlling the release timing of the thrust and pull of the driving mechanism 201, thereby reducing the noise generated when the game controller brings a vibration sensation to the player during use.

[0042] Figure 3 A flowchart of a noise reduction method for a force feedback device provided in one embodiment of the present application.

[0043] Reference Figure 3 As shown, the method may include the following steps:

[0044] Step 301: Before the vibrating rod performs a first movement, calculate the first time for the vibrating rod to complete the first movement.

[0045] In order to realize the first movement of the vibration rod 202, the driving mechanism 201 of the force feedback device provides a thrust to the vibration rod 202, and drives the vibration rod 202 to move from the first position to the second position through the thrust. In one embodiment, the shape of the vibration rod 202 can be as follows: Figure 2As shown, when the driving mechanism 201 provides thrust to the vibration rod 202, the vibration rod 202 rotates about its rotation axis and rotates to the second position. After the vibration rod rotates to the second position, the driving mechanism 201 provides pulling force to the vibration rod 202, and drives the vibration rod 202 to return from the second position to the first position through the pulling force, thereby controlling the vibration rod 202 to complete a reciprocating motion. The driving mechanism 201 can drive the vibration rod 202 to complete multiple reciprocating motions at a set frequency, thereby realizing the vibration of the vibration rod at the set frequency, thereby providing a vibration sense to the player using the handle and improving the tactile experience of the game.

[0046] In one embodiment, Figure 2 As shown, the driving mechanism can be a motor, which is used in conjunction with the vibration rod through a driving rod. The outer surface of the driving rod can be a threaded structure, and the threaded structure cooperates with the gear structure that controls the rotation of the vibration rod 202, that is, the driving rod and the gear form a master-slave relationship (the driving rod actively controls the gear to follow). Then, when the driving rod of the motor rotates in one direction (for example, clockwise), the gear drivenly controls the vibration rod 202 to rotate from the first position to the second position to complete the first motion. After the vibration rod 202 reaches the second position, the driving rod of the motor rotates in the opposite direction (for example, counterclockwise), and the gear drivenly controls the vibration rod 202 to return from the second position to the first position to complete the second motion, and then the vibration rod 202 completes a reciprocating motion.

[0047] In order to improve the accuracy of the movement position of the driven vibration rod 202, specifically to reduce the possibility of the vibration rod 202 colliding with the adjacent structure below when performing the first movement, the first time required for the vibration rod 202 to complete the first movement can be calculated before the vibration rod 202 performs the first movement, so that the driving mechanism can control the release timing of the thrust and pull of the driving mechanism 201 according to the estimated time, thereby improving the accuracy of the movement position of the driven vibration rod 202 and reducing the possibility of the vibration rod 202 colliding with the adjacent structure below when performing the first movement.

[0048] In one embodiment, the first time required for the vibration rod 202 to complete the first movement this time may be calculated based on the first position information and the second position information of the vibration rod 202 , the driving strength of the driving mechanism 201 , and the correction coefficient.

[0049] The vibration-enabled handle can be pre-set with respect to the driving intensity (amplitude) and driving frequency of the driving mechanism 201 in the force feedback device before use by the user. In one embodiment, the driving mechanism can be a motor for providing force feedback; therefore, the driving intensity represents the strength of the force feedback provided by the driving mechanism, i.e., the magnitude of the driving force.

[0050] The first position information and the second position information of the vibration rod 202 when performing the first motion and the second motion can also be determined in advance before the handle is used by the user. In an embodiment, the first position information can be the position information of the protective cap 203 as shown in the figure, and the second position information can be the position information of the return position when the vibration rod 202 performs the reciprocating motion. Figure 2

[0051] It should be noted that the second position can be a fixed position on the motion path of the vibration rod 202, or can be a non-fixed position on the motion path of the vibration rod 202.

[0052] In an embodiment, if the second position is set as a fixed position on the motion path of the vibration rod 202, when a vibration event occurs in the game, all vibration event trigger force feedback device vibrations are the vibration rod 202 performing reciprocating motion between the position of the protective cap 203 and the fixed second position, thereby providing the user with a fixed vibration sensation.

[0053] In another embodiment, if the second position is set as a non-fixed position on the motion path of the vibration rod 202, in actual application, when a vibration event occurs in the game, the vibration level of the current vibration event can be determined, and the actual position of the second position corresponding to the vibration of the force feedback device this time can be determined according to the vibration level of the current vibration event.

[0054] Among them, the vibration events occurring in the game can be classified in advance, and in an embodiment, the classification can be based on the game scene type. For example, the classification table of the vibration event is shown in Table 1:

[0055] Table 1

[0056] Gameplay scenario Vibration event level Sports batting scenario Primary vibration Fighting punch scenario Secondary vibration Driving crash scenario Tertiary vibration Explosion scenario Quaternary vibration

[0057] As shown in Table 1, in this embodiment, the game scene triggering the vibration event can be divided into three types, namely, the motion hitting scene, the fighting hitting scene, the driving impact scene, and the explosion scene. For example, when the player controls the game character to hit a tennis ball through the handle, the vibration event triggered is a first-level vibration; when the player plays a fighting game, the vibration event triggered when the game character controlled by the player is hit is a second-level vibration; when the player controls a vehicle in the game to collide through the handle, the vibration event triggered is a third-level vibration; when the player plays a war game, the vibration event triggered when an explosion occurs within a certain range of the game character or vehicle controlled by the player is a fourth-level vibration. Among them, the vibration sensation provided to the player by the first-level vibration to the fourth-level vibration is enhanced step by step.

[0058] ​The embodiments of the present application do not limit how to divide the vibration event levels, in other embodiments, the vibration levels can also be divided based on other manners, and the number of vibration levels is also not limited.

[0059] In an embodiment, the second positions corresponding to the levels of each vibration event are different, and the specific matching manners are shown in Table 2.

[0060] Table 2

[0061] Vibration event level Second position Primary vibration Second position A Secondary vibration Second position B Tertiary vibration Second position C Quaternary vibration Second position D

[0062] As shown in Table 2, the actual positions of the second positions corresponding to the current vibration event are matched according to the vibration event levels. Among them, the first-level vibration corresponds to the second position A, the second-level vibration corresponds to the second position B, the third-level vibration corresponds to the second position C, and the fourth-level vibration corresponds to the second position D. Since the vibration sensation provided to the player by the preset first-level vibration to fourth-level vibration is gradually enhanced, in order to realize the gradual enhancement of the vibration sensation, the actual positions of the second positions corresponding to different vibration levels can be set to be different. For example, the driving frequency of the driving mechanism 201 of the force feedback device can be fixed, and different driving strengths are output based on the levels of different vibration events, so that in the case that the actual positions of the second positions corresponding to different vibration levels are different, the driving vibration rod 202 moves from the first position to the second position (the second position A, the second position B, the second position C or the second position D) in the same or similar time, thereby providing different vibration sensations to the player. Among them, the movement distance of the vibration rod 202 from the first position to the second position A is L (A) , the movement distance from the first position to the second position B is L (B) , the movement distance from the first position to the second position C is L (C) , and the movement distance from the first position to the second position D is L (D) . And the movement distance L (A) to the movement distance L (D) gradually increases, that is, L (A) <L (B) <L (C) <L (D) .

[0063] In an embodiment, the first time required by the vibration rod 202 to complete the first movement based on the first position information, the second position information, the driving strength of the driving mechanism 201 and the correction coefficient can include being calculated through formula one as follows:

[0064] t1=K / A*(P2+1–P1) Formula one

[0065] Wherein, t1 represents the first time required for the vibration rod 202 to complete the first motion this time, P1 represents the first position information, P2 represents the second position information, A represents the driving strength of the driving mechanism 201, and K represents the correction coefficient applicable to the current.

[0066] In the above manner, the first time t1 required for the vibration rod 202 to complete the first motion this time can be calculated before the driving mechanism 201 drives the vibration rod 202 to perform the first motion.

[0067] Step 302: The driving mechanism controls the vibration rod to stop the first motion after a first time from the start of driving the vibration rod to perform the first motion.

[0068] Wherein, after the first time t1 required for the vibration rod 202 to complete the first motion this time is calculated through step 301, the driving mechanism 201 can start timing when it releases the thrust to drive the vibration rod 202 to start performing the first motion, and stop releasing the thrust after t1 time, and then can control the vibration rod 202 to stop moving after t1 time, thereby improving the accuracy of controlling the vibration rod to move and reducing the possibility of the vibration rod hitting the adjacent structure below to cause noise.

[0069] In some embodiments, when the vibration rod 202 performs the second motion, the second time required for the vibration rod to complete the second motion this time can also be calculated, and the vibration rod 202 is controlled to stop the second motion based on the calculated second time, thereby reducing the possibility of the vibration rod 202 hitting the protective cap 203 to cause noise, thereby improving user experience. This can be achieved through the following steps:

[0070] Step 303: Calculate the second time required for the vibration rod to perform the second motion according to the driving frequency of the driving mechanism.

[0071] Wherein, the driving frequency of the driving mechanism 201 can be a frequency set by the user in advance. For example, the driving frequency is set to 2Hz, and then the second time required for the vibration rod 202 to perform the second motion can be calculated according to the driving frequency (such as 2Hz) of the driving mechanism 201.

[0072] In one embodiment, the second time required for the vibration rod 202 to perform the second motion can be calculated by the following Formula Two:

[0073] t2 = 1 / (2*F) Formula Two

[0074] Wherein, t2 represents the second time required for the vibration rod 202 to perform the second motion, and F represents the driving frequency of the driving mechanism 201. For example, if the driving frequency of the driving mechanism 201 is 2Hz, then the second time required for the vibration rod 202 to perform the second motion can be calculated based on the above Formula Two to be 250ms.

[0075] In the above manner, the second time t2 required for the vibration rod 202 to complete the second movement this time can be calculated before the driving mechanism 201 drives the vibration rod 202 to perform the second movement.

[0076] Step 304: The driving mechanism controls the vibration rod to stop the second movement after the second time elapses since the driving of the vibration rod to start the second movement.

[0077] After the second time t2 required for the vibration rod 202 to complete the second movement this time is calculated through step 303, the driving mechanism 201 can start timing when the driving of the vibration rod 202 to start the second movement is released, and stop releasing the tension after t2 elapses, so as to control the vibration rod 202 to stop moving after t2 elapses, thereby improving the accuracy of controlling the movement of the vibration rod and reducing the possibility of noise caused by the vibration rod hitting the protective cap 203.

[0078] In each reciprocating movement stage of the force feedback device required to perform reciprocating movement to realize vibration, the above steps 301 to 304 can be used to improve the accuracy of driving the vibration rod 202, reduce the possibility of noise caused by the vibration rod 202 hitting other structures, and improve the user experience.

[0079] The corresponding control module of the gamepad controls the target force feedback device to vibrate, enriches the way for the player to obtain the tactile sensation from the gamepad, increases the amount of current scene information obtained from the gamepad, and thus can make a faster and more accurate judgment and reaction operation, thereby improving the game experience of the player.

The gamepad provided in the embodiment not only serves as an input device for game control, but also serves as an output device for feeding back the game information to the player, and thus the game experience of the player is improved.
