Description

[Technical Field]

[0001] This invention relates to the field of haptic feedback technology, and more particularly to a method, apparatus, electronic terminal, and computer-readable storage medium for converting haptic feedback. [Background Technology]

[0002] Haptics, or haptic technology, is a haptic feedback mechanism that combines hardware and software, supplemented by actions such as force or vibration, to simulate the realistic tactile experience of humans. Currently, with the widespread adoption of haptics on mobile phones, more and more mobile applications are incorporating haptics experiences. Examples include button clicks, presses, releases, and long presses; phone vibrations during incoming calls; vibration alerts for text messages; and continuous vibrations for alarm clocks. In mobile games, haptics performs even better, using motors to simulate realistic haptic feedback between the fingers based on different scenarios and characters, providing players with a truly immersive gaming experience.

[0003] In existing technologies, when electronic terminals such as mobile phones and tablets incorporate haptics experiences, there is often a transition in haptic feedback. This means that while application A is performing a haptics experience (i.e., the motor is vibrating), it is interrupted by application B, which also incorporates haptics (and application B also needs to vibrate). For example, a user playing a game with haptics might be interrupted by the phone's vibration during a ringtone. The traditional method of transitioning haptic feedback is to immediately stop application A's vibration regardless of its vibration level, and then send the vibration waveform from application B. Although application A's vibration stops immediately, the residual vibration caused by the motor's characteristics significantly affects application B's vibration waveform. This causes the vibration waveforms from application A and application B to overlap, resulting in a muddy and uncomfortable vibration feel, impacting the user experience. Furthermore, the rapid stop and return to full amplitude of the motor during this process can easily cause motor damage.

[0004] Therefore, it is necessary to improve the above-mentioned tactile feedback conversion method. [Summary of the Invention]

[0005] The purpose of this invention is to provide a method, device, electronic terminal, and computer-readable storage medium for converting haptic feedback, thereby solving the problems of poor user experience and motor malfunction caused by haptic feedback conversion in the prior art.

[0006] The technical solution of the present invention is as follows:

[0007] The first aspect of this invention provides a method for converting haptic feedback, applied when application A is providing haptic feedback and is interrupted by application B, which also needs to provide haptic feedback, including:

[0008] Adjust the vibration transmission of application A so that the amplitude of application A decreases from the current amplitude to zero amplitude within a first preset time.

[0009] Simultaneously, the vibration transmission of application B is adjusted so that the amplitude of application B increases from zero amplitude to the amplitude required by application B within a second preset time.

[0010] In some embodiments, adjusting the vibration transmission of application A, such that the amplitude of application A decreases from its current amplitude to zero amplitude within a first preset time period, includes:

[0011] Detect whether the event corresponding to application B has occurred;

[0012] If an event corresponding to application B occurs, the vibration of application A is adjusted so that the amplitude of application A decreases from the current amplitude to zero amplitude within a first preset time.

[0013] In some embodiments, the first preset time is equal to the second preset time, and both are 2ms; or

[0014] The first preset time is greater than the second preset time; or

[0015] The first preset time is less than the second preset time.

[0016] A second aspect of this invention provides another method for converting haptic feedback, applied when application A is providing haptic feedback and is interrupted by application B, which also requires haptic feedback, including:

[0017] Adjust the vibration transmission of application A so that the amplitude of application A decreases from the current amplitude to zero amplitude at a first rate of change;

[0018] Simultaneously, the vibration of application B is adjusted so that the amplitude of application B increases from zero amplitude to the amplitude required by application B at a second rate of change.

[0019] In some embodiments, adjusting the vibration transmission of application A, such that the amplitude of application A decreases from its current amplitude to zero amplitude at a first rate of change, includes:

[0020] Detect whether the event corresponding to application B has occurred;

[0021] If an event corresponding to application B occurs, the vibration of application A is adjusted so that the amplitude of application A decreases from the current amplitude to zero amplitude at a first rate of change.

[0022] In some embodiments, the time it takes for application A to decrease from its current amplitude to zero amplitude is equal to the time it takes for application B to increase from zero amplitude to the amplitude required for application B, and both are preset times. Adjusting the vibration transmission of application A so that its amplitude decreases from its current amplitude to zero amplitude at a first rate of change includes:

[0023] Based on the preset time and the difference between the current amplitude and zero amplitude of application A, determine the first rate of change when adjusting the vibration transmission of application A;

[0024] The vibration of application A is adjusted according to the first rate of change, so that the amplitude of application A decreases from the current amplitude to zero amplitude at the first rate of change.

[0025] In some embodiments, adjusting the vibration transmission of application B such that the amplitude of application B increases from zero amplitude to the amplitude required by application B at a second rate of change includes:

[0026] Based on the preset time and the difference between the amplitude required by application B and zero amplitude, determine the second rate of change when adjusting the vibration of application B.

[0027] The vibration of application B is adjusted according to the second rate of change, so that the amplitude of application B increases from zero amplitude to the amplitude required by application B at the second rate of change.

[0028] A third aspect of the present invention provides a haptic feedback conversion device, applied when application A is providing haptic feedback and is interrupted by application B, which also requires haptic feedback, including:

[0029] The first adjustment module is used to adjust the vibration transmission of application A, so that the amplitude of application A is reduced from the current amplitude to zero amplitude within a first preset time.

[0030] The second adjustment module is used to simultaneously adjust the vibration transmission of application B, so that the amplitude of application B increases from zero amplitude to the amplitude required by application B within a second preset time.

[0031] A fourth aspect of the present invention provides another haptic feedback conversion device, applied when application A is providing haptic feedback and is interrupted by application B, which also requires haptic feedback, including:

[0032] The first adjustment module is used to adjust the vibration transmission of application A, so that the amplitude of application A decreases from the current amplitude to zero amplitude at a first rate of change.

[0033] The second adjustment module is used to simultaneously adjust the vibration transmission of application B, so that the amplitude of application B increases from zero amplitude to the amplitude required by application B at a second rate of change.

[0034] A fifth aspect of the present invention provides an electronic terminal, including a storage device and one or more processors, wherein the storage device is used to store one or more programs, and when the one or more programs are executed by the one or more processors, the one or more processors perform the method as described in the first or second aspect of the present invention.

[0035] A sixth aspect of the present invention provides a computer-readable storage medium storing executable instructions, which, when executed, perform the method described in the first or second aspect of the present invention.

[0036] As can be seen from the above description, compared with the prior art, the beneficial effects of the present invention are as follows:

[0037] When application A is providing haptic feedback but is interrupted by application B, which also requires haptic feedback, the amplitude of application A decreases from its current amplitude to zero within a first preset time or at a first rate of change. Meanwhile, the amplitude of application B increases from zero amplitude to the amplitude required by application B within a second preset time or at a second rate of change. This prevents application A from being abruptly interrupted, reduces motor aftershocks, and prevents the vibrations of application B from overlapping with the aftershocks of application A. This provides users with a clear and comfortable haptic feedback, improves the user experience, ensures smooth transitions during haptic feedback, and prevents the motor from rapidly stopping and then quickly returning to full amplitude, effectively reducing motor malfunctions.

Detailed Implementation Methods

[0044] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. Throughout the description, the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. Furthermore, the technical features involved in the various embodiments of the invention described below can be combined with each other as long as they do not conflict with each other.

[0045] Please see Figure 1 , Figure 1 This is a flowchart illustrating a tactile feedback conversion method provided in an embodiment of the present invention.

[0046] like Figure 1 As shown, this embodiment of the invention provides a method for switching haptic feedback, applied to the switching of haptic feedback between application A and application B. Specifically, it is applied when application A is generating haptic feedback and is interrupted by application B, which also needs to generate haptic feedback. This haptic feedback switching method includes the following steps S11 to S12.

[0047] S11. Adjust the vibration transmission of application A so that the amplitude of application A decreases from the current amplitude to zero amplitude within a first preset time.

[0048] Before proceeding to step S11, it is necessary to detect in real time whether the event corresponding to application B has occurred. It should be understood that if the event corresponding to application B occurs, it means that application B needs to use a motor to vibrate in order to achieve tactile feedback. This will inevitably interrupt the tactile feedback that application A is currently experiencing. When the event corresponding to application B is detected, it is not necessary to immediately stop the vibration of application A to meet the vibration of application B. Instead, the vibration of application A is adjusted within a certain period of time (i.e., the first preset time in step S11) so that the amplitude of application A is reduced from the current amplitude to zero amplitude within the first preset time, such as from full amplitude to zero amplitude within 2ms.

[0049] S12. Simultaneously adjust the vibration transmission of application B, so that the amplitude of application B increases from zero amplitude to the amplitude required by application B within a second preset time.

[0050] During the process of the amplitude of application A decreasing from its current amplitude to zero amplitude, the amplitude of application B needs to be adjusted simultaneously. However, it is not necessary to immediately increase the amplitude of application B from zero amplitude to the amplitude required by application B. Instead, the vibration of application B is adjusted within a certain period of time (i.e., the second preset time in step S12) so that the amplitude of application B increases from zero amplitude to the amplitude required by application B within the second preset time, such as increasing from zero amplitude to full amplitude within 2ms.

[0051] As can be seen from the above description of steps S11 and S12, the first preset time can be 2ms, and the second preset time can also be 2ms, that is, the first preset time and the second preset time can be equal. However, it should be understood that in other embodiments, the first preset time can be greater than the second preset time, or the first preset time can be less than the second preset time. This is determined based on the operation of the chip in electronic terminals such as mobile phones and tablets, and the embodiments of the present invention do not limit this.

[0052] In the haptic feedback conversion method provided in this embodiment of the invention, when application A is providing haptic feedback but is interrupted by application B, which also requires haptic feedback, the amplitude of application A decreases from its current amplitude to zero amplitude within a first preset time, and the amplitude of application B increases from zero amplitude to the amplitude required by application B within a second preset time. This prevents application A from being abruptly interrupted, reduces motor aftershocks, and prevents the vibration of application B from overlapping with the aftershocks of application A. This provides the user with a clear and comfortable vibration feel, improves the user experience, ensures the smoothness of haptic feedback conversion, and prevents the motor from quickly stopping and then quickly reaching full amplitude, effectively reducing motor malfunction.

[0053] Please refer to further information. Figure 2 , Figure 2 This is a flowchart illustrating another tactile feedback conversion method provided in an embodiment of the present invention.

[0054] like Figure 2 As shown, this embodiment of the invention provides another method for switching haptic feedback, applied to the switching of haptic feedback between application A and application B. Specifically, it is applied when application A is giving haptic feedback and is interrupted by application B, which also needs to give haptic feedback. This haptic feedback switching method includes the following steps S21 to S22.

[0055] S21. Adjust the vibration transmission of application A so that the amplitude of application A decreases from the current amplitude to zero amplitude at a first rate of change;

[0056] Before proceeding to step S21, it is necessary to detect in real time whether the event corresponding to application B has occurred. It should be understood that if the event corresponding to application B occurs, it means that application B needs to use a motor to vibrate in order to achieve haptic feedback. This will inevitably interrupt the haptic feedback that application A is currently experiencing. When the event corresponding to application B is detected, it is not necessary to immediately stop the vibration of application A to meet the vibration of application B. Instead, the vibration of application A is adjusted at a certain rate (i.e., the first rate of change in step S21) so that the amplitude of application A is reduced from the current amplitude to zero amplitude at the first rate of change.

[0057] S22. Simultaneously adjust the vibration of application B, so that the amplitude of application B increases from zero amplitude to the amplitude required by application B at a second rate of change.

[0058] During the process of the amplitude of application A decreasing from its current amplitude to zero amplitude, the amplitude of application B needs to be adjusted simultaneously. However, it is not necessary to immediately increase the amplitude of application B from zero amplitude to the amplitude required by application B. Instead, the vibration of application B is adjusted at a certain rate (i.e., the second rate of change in step S22) so that the amplitude of application B increases from zero amplitude to the amplitude required by application B at the second rate of change.

[0059] As a feasible implementation, the time for application A to decrease from its current amplitude to zero amplitude at a first rate of change can be equal to the time for application B to increase from zero amplitude to the amplitude required by application B at a second rate of change (hereinafter referred to as the preset time). In this case, the first rate of change can be determined based on the preset time and the difference between the current amplitude and zero amplitude of application A, and the second rate of change can be determined based on the preset time and the difference between the amplitude required by application B and zero amplitude.

[0060] It should be understood that the relationship between the first rate of change and the second rate of change is related to the preset time, the difference between the current amplitude and zero amplitude of application A, and the difference between the amplitude required by application B and zero amplitude. Therefore, the first rate of change can be equal to, less than, or greater than the second rate of change. This embodiment of the invention does not limit this.

[0061] In the haptic feedback conversion method provided in this embodiment of the invention, when application A is providing haptic feedback but is interrupted by application B, which also requires haptic feedback, the amplitude of application A decreases from its current amplitude to zero amplitude at a first rate of change, while the amplitude of application B increases from zero amplitude to the amplitude required by application B at a second rate of change. This prevents application A from being abruptly interrupted, reduces motor aftershocks, and ensures that the vibrations of application B do not overlap with the aftershocks of application A. This provides the user with a clear and comfortable vibration feel, improves the user experience, ensures the smoothness of haptic feedback conversion, and prevents the motor from quickly stopping and then rapidly reaching full amplitude, effectively reducing motor malfunction.
