Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail and completely with reference to the following specific embodiments of the present application and the accompanying drawings. It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The terminology used in the description of the embodiments section of the present application is for the purpose of describing particular embodiments of the present application only and is not intended to be limiting of the present application.
The application provides a vibration driving signal generation method aiming at the problems that in the application scene of vibration touch experience in the prior art, the user touch experience is not ideal and the user experience is reduced. To propose the method of the embodiment of the present application, the inventors first analyze the actual application scenario for implementing a haptic experience based on vibration effects.
Generally, in a technical scheme for realizing haptic experience based on a vibration effect, an application program generates a vibration driving signal for driving a vibration motor, and the motor operates under the driving of the vibration driving signal, thereby realizing vibrotactile sensation. However, in practical application scenarios, the vibrotactile sensations corresponding to different application scenarios are different, and if a uniform vibrotactile sensation is used, an ideal user tactile experience must be achieved. Therefore, in a feasible haptic experience application scheme, when haptic experience is realized through a vibration effect, different vibration effects are realized through the change of intensity, so that various haptic experiences are brought, various different haptic experience application scenes are adapted, and the user experience is improved.
Further, based on the above scheme, although different haptic experience application scenarios can be realized, different vibration effect settings can be selected. However, in practical applications, the alternative vibration effects are usually pre-designed and integrated into the device. Since the preset vibration effect is very limited, it cannot cover all the haptic experience application scene requirements, so the preset vibration effect cannot perfectly match all the haptic experience application scenes. This results in some haptic experience application scenarios where the preset vibration effect does not provide the user with a desirable haptic experience.
For example, in an application scene, the usage environment of the device is a quieter place, and the user is more sensitive to the vibration touch feeling in the current application scene than in a noisy environment. In a typical manufacturer setting, the vibration effect is not differentiated by the noise level of the usage environment. In this application scenario, when the user triggers the vibration touch, if the application program directly calls the vibration effect setting in the vendor setting to generate the vibration driving signal, the finally generated vibration effect will often make the user feel a "frightening one jump".
Further, when the vibration effect is set in advance, since the coverage of the preset vibration effect setting needs to be as wide as possible, the preset vibration effect setting cannot be set specifically for the individual tactile habits of the user. Under the condition of not considering the personal tactile habit of the user, in some application scenes, the preset vibration effect cannot bring ideal tactile experience to the user and can possibly reduce the user experience.
For example, for a user, the user's perception of vibrotactile sensations is relatively insensitive as compared to most people. When the user triggers the vibration touch, if the application program directly calls the vibration effect setting in the preset to generate the vibration driving signal, the finally generated vibration effect cannot be clearly perceived by the user. For another example, for a user, the user is relatively sensitive to the perception of vibrotactile sensations as compared to most people. When the user triggers the vibration touch, if the application program directly calls the preset vibration effect setting to generate the vibration driving signal, the finally generated vibration effect is likely to cause pain to the user.
Based on the above analysis, one of the reasons for the problems of the user experience being unsatisfactory and the user experience being degraded is that the vibration effect used to implement the user haptic experience does not match the haptic experience application scene requirements and/or the user haptic experience requirements. Therefore, if the vibration driving signal generated by the application program can be modified according to the specific haptic experience application scene requirement and/or the user haptic experience requirement, so that the final vibration effect matches the haptic experience application scene requirement and/or the user haptic experience requirement, the problem of non-ideal user haptic experience can be solved, and the user experience can be improved.
Based on the above analysis, in an embodiment of the present application, a method for generating a vibration driving signal is provided. In the method of the embodiment, based on the haptic experience application scene requirement and/or the user haptic experience requirement, the vibration driving signal generated by the application program is adjusted from the signal intensity, the intensity variation pattern and the intensity variation speed variation pattern in three aspects to obtain a new vibration driving signal, and the motor is driven by the new vibration driving signal to generate a vibration effect which can achieve matching with the haptic experience application scene requirement and/or the user haptic experience requirement.
The technical solutions provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.
Fig. 1 is a flowchart illustrating an embodiment of a method for generating an oscillating driving signal according to the present application. In an embodiment of the present application, as shown in fig. 1, the vibration driving signal generating method includes:
the initial signal of the first driving signal is generated by adjusting the initial signal of the original driving signal according to the initial intensity adjustment parameter;
the time-dependent intensity variation pattern and the time-dependent intensity variation velocity variation pattern of the first driving signal are respectively the time-dependent intensity variation pattern and the time-dependent intensity variation velocity variation pattern described by the intensity variation parameter and the velocity variation parameter.
According to the method and the flow, the vibration touch parameters of the user are matched with the requirements of the haptic experience application scene and/or the requirements of the haptic experience of the user, so that the vibration effect realized by the first driving signal obtained by calculating the original driving signal is adjusted based on the vibration touch parameters of the user, and the requirements of the haptic experience application scene and/or the requirements of the haptic experience of the user can be met. Compared with the prior art, the method provided by the embodiment can provide better tactile experience for the user, improve the ideality of the tactile experience of the user and improve the user experience.
Fig. 2 is a schematic diagram illustrating data flow according to an embodiment of the present application. As shown in fig. 2, the user vibrotactile parameters 201 are input to the data processor 210, and the data processor 210 reads the raw driving signals from the memory 202.
The data processor 210 generates a first driving signal 220 according to the user vibrotactile parameter and the original driving signal calculation, and the first driving signal 220 is output to the motor 230 to realize the vibration effect.
Further, in an embodiment of the present application, the initial intensity adjustment parameter includes an intensity multiple. The first initialization signal is a signal generated by amplifying or reducing the initialization signal of the original driving signal by an intensity multiple. Specifically, in one implementation of step 130, in the process of adjusting the initial signal of the original driving signal according to the initial strength adjustment parameter to generate the first initial signal, the initial signal of the original driving signal is amplified or reduced by a strength multiple to generate the first initial signal.
For example, in an application scenario according to one implementation of step 130, in the process of adjusting the initial signal of the original driving signal according to the initial intensity adjustment parameter to generate the first initial signal, after reading the original driving signal in the storage, the whole signal is enlarged or reduced by s1Multiple, in the above process s1The value is the setting value of the intensity multiple in the initial intensity adjustment parameter.
For another example, in an application scenario according to an implementation manner of step 130, in the process of adjusting the initial signal of the original driving signal according to the initial intensity adjustment parameter to generate the first initial signal, after reading the original driving signal in the storage, the vibration amplitude of the whole signal is amplified or reduced by s2Multiple, in the above process s2The value is the setting value of the intensity multiple in the initial intensity adjustment parameter.
Further, considering that the variation of the vibration amplitude directly results in the variation of the vibration intensity, in an embodiment of the present application, the vibration intensity is adjusted by adjusting the vibration amplitude. Specifically, a parameter for describing a change pattern of the vibration amplitude of the drive signal with time is defined in the intensity change parameter.
In particular, it is considered that the amplitude gradient is a common intensity variation mode. Therefore, in an embodiment of the present application, the intensity variation parameter includes a magnitude gradient parameter for describing a magnitude gradient manner.
In other embodiments of the present application, the intensity variation parameter may also include a parameter for describing other amplitude variation modes, for example, an amplitude period variation parameter for describing a specific variation mode of the amplitude period variation.
Specifically, in an embodiment of the present application, the strength variation parameter includes a first amplitude gradation parameter for describing an amplitude increasing speed or an amplitude decreasing speed of the vibration. The variation pattern of the intensity of the first driving signal is: from the beginning to the end of the first driving signal, the vibration amplitude of the first initial signal is enhanced according to the vibration amplitude enhancement speed of the first amplitude gradient parameter or the vibration amplitude of the first initial signal is weakened according to the vibration amplitude weakening speed of the first amplitude gradient parameter. That is, in one implementation of step 130, in the process of generating the first initial signal, from the beginning to the end of the signal, the vibration amplitude of the first initial signal is enhanced according to the vibration amplitude enhancement rate of the first amplitude ramp parameter or the vibration amplitude of the first initial signal is attenuated according to the vibration amplitude attenuation rate of the first amplitude ramp parameter to generate the first driving signal.
Specifically, in an embodiment of the present application, the intensity variation parameter includes a second amplitude gradient parameter for describing an amplitude final value of the vibration. The variation pattern of the intensity of the first driving signal is: from the beginning to the end of the first driving signal, the vibration amplitude of the first initial signal is enhanced according to a first preset increment rule or the vibration amplitude of the first initial signal is weakened according to a first preset decrement rule, so that the vibration amplitude at the end of the first driving signal is the vibration amplitude final value. That is, in step 130, in one implementation, during the generation of the first driving signal, from the beginning to the end of the signal, the vibration amplitude of the first initial signal is enhanced according to a first preset increment rule or the vibration amplitude of the first initial signal is attenuated according to a first preset decrement rule, so that the intensity at the end of the signal is the vibration amplitude end value to generate the first driving signal.
Specifically, in the above embodiment, the first preset increment rule and the first preset decrement rule may be any increment/decrement rules. For example, stepwise increment/decrement is performed while maintaining a fixed increment/decrement value, or linear increment/decrement is performed while maintaining a fixed increment/decrement speed, or the intensity is held to a specific increment/decrement curve.
For example, in one implementation of step 130, in the process of generating the first driving signal, from the beginning to the end of the signal, the vibration amplitude of the first initial signal is enhanced by maintaining a constant vibration amplitude enhancement speed or the vibration amplitude of the first initial signal is attenuated by maintaining a constant vibration amplitude attenuation speed, so that the intensity at the end of the signal is the vibration amplitude final value to generate the first driving signal.
Specifically, in an embodiment of the present application, the intensity variation parameter includes a third amplitude gradient parameter. The variation pattern of the intensity of the first driving signal is: and from the beginning to the end of the first driving signal, enhancing the vibration amplitude of the first initial signal according to a second preset increment rule or weakening the vibration amplitude of the first initial signal according to a second preset decrement rule, so that the intensity of the first driving signal at the end is the intensity corresponding to the parameter value of the third amplitude gradual change parameter. That is, in one implementation manner of step 130, during the process of generating the first driving signal, from the beginning to the end of the signal, the vibration amplitude of the first initial signal is enhanced according to a second preset increment rule or the vibration amplitude of the first initial signal is weakened according to a second preset decrement rule, so that the intensity at the end of the signal is the intensity corresponding to the third amplitude gradual change parameter to generate the first driving signal.
For example, in an application scenario, the setting value of the third amplitude ramp parameter ranges from [0 to + ∞ ], where:
the larger the set value of the third amplitude gradient parameter is, the larger the corresponding intensity is;
when the set value of the third amplitude gradient parameter is 0, the corresponding intensity is 0;
when the set value of the third amplitude gradient parameter is 1, the corresponding intensity is the intensity of the first initial signal;
when the set value of the third amplitude gradient parameter is + ∞, the corresponding intensity is maximum.
Specifically, in the application scenario, an open parameter interface is provided to obtain a final value of the vibration amplitude corresponding to the third gradient parameter with the setting value of + ∞. When the set value of the third amplitude gradient parameter is + ∞, the final value of the vibration amplitude is the maximum intensity that the vibration device can realize.
Specifically, in the above embodiment, the second preset increment rule and the second preset decrement rule may be any increment/decrement rules. For example, stepwise increment/decrement is performed while maintaining a fixed increment/decrement value, or linear increment/decrement is performed while maintaining a fixed increment/decrement speed, or the intensity is held to a specific increment/decrement curve.
For example, in one implementation of step 130, in the process of generating the first driving signal, from the beginning to the end of the signal, the vibration amplitude of the first initial signal is enhanced by maintaining a constant vibration amplitude enhancement speed or the vibration amplitude of the first initial signal is attenuated by maintaining a constant vibration amplitude attenuation speed, so that the intensity at the end of the signal is the intensity corresponding to the third amplitude ramp parameter to generate the first driving signal.
Fig. 3 is a schematic diagram illustrating third amplitude ramp parameter setting according to an embodiment of the present application. As shown in fig. 3, the setting value of the third amplitude ramp parameter is a parameter value α. When the third amplitude gradual change parameter alpha is set to be 1, the intensity of the signal at the end is consistent with that of the signal at the beginning, and the intensity is kept unchanged; when the third amplitude gradual change parameter alpha is set to be 0, the weakest intensity at the end of the signal is 0; when the third amplitude ramp parameter α is set to + ∞, it indicates that the intensity is strongest at the end of the signal. Since the input value of the intensity cannot be input to + ∞, an open parameter interface is provided to obtain the final value of the vibration amplitude corresponding to the setting value of the third amplitude gradient parameter to + ∞. When the set value of the third amplitude gradient parameter is + ∞, the final value of the vibration amplitude is the maximum intensity that the vibration device can realize.
Further, it is contemplated that velocity ramping is a common variation of the rate of intensity change. Therefore, in an embodiment of the present application, the speed variation parameter includes a speed fade parameter for describing a speed fade mode.
In other embodiments of the present application, the speed variation parameter may also include a parameter for describing other speed variation modes, for example, a speed cycle variation parameter for describing a specific variation mode of the intensity variation speed cycle variation.
Specifically, in one embodiment, the speed variation parameter includes a first speed ramp parameter for describing a rate of increase of the intensity variation speed or a rate of decrease of the intensity variation speed. The variation pattern of the intensity variation speed of the first driving signal is as follows: from the start to the end of the first drive signal, the intensity change speed of the first initial signal is increased at an increasing speed of the intensity change speed or decreased at a decreasing speed of the intensity change speed.
Specifically, in step 130, in one implementation, in the process of generating the first initial signal, from the beginning to the end of the signal, the intensity change speed of the first initial signal is increased according to the increasing speed of the intensity change speed or the intensity change speed of the first initial signal is decreased according to the decreasing speed of the intensity change speed to generate the first driving signal.
Specifically, in one embodiment, the speed variation parameter includes a second speed ramping parameter for describing a final value of the intensity variation speed. The variation pattern of the intensity variation speed of the first driving signal is as follows: and increasing the intensity change speed of the first initial signal according to a third preset increment rule or decreasing the intensity change speed of the first initial signal according to a third preset decrement rule from the beginning to the end of the first driving signal, so that the intensity change speed at the end of the first driving signal is the intensity change speed final value. That is, in one implementation of step 130, during the generation of the first driving signal, the intensity change rate of the first initial signal is increased according to a third preset increment rule or decreased according to a third preset decrement rule from the beginning to the end of the signal, so that the intensity change rate at the end of the first driving signal is the intensity change rate end value.
For example, in an application scenario, the set value of the second speed ramping parameter ranges from [ - ∞ - + ∞ ], where:
the larger the set value of the second speed gradual change parameter is, the larger the final value of the intensity change speed is;
when the set value of the second speed gradual change parameter is 0, the final value of the intensity change speed is the intensity change speed of the first initial signal;
when the set value of the second speed gradual change parameter is + ∞, the final value of the intensity change speed is the maximum intensity change speed which can be realized by the vibration equipment;
when the set value of the second speed gradual change parameter is- ∞, the final value of the intensity change speed is the minimum intensity change speed which can be realized by the vibrating equipment.
Specifically, in the above embodiment, the third preset increment rule and the third preset decrement rule may be any increment/decrement rules. For example, stepwise increment/decrement is performed while maintaining a fixed increment/decrement value, or linear increment/decrement is performed while maintaining a fixed increment/decrement speed, or the intensity is held to a specific increment/decrement curve.
For example, in one implementation of step 130, in the process of generating the first driving signal, the intensity change speed of the first initial signal is increased while maintaining a constant change speed increase speed or decreased while maintaining a constant change speed decrease speed from the beginning to the end of the signal, so that the intensity change speed at the end of the first driving signal is the intensity change speed end value.
Fig. 4 is a diagram illustrating a second speed ramp parameter setting according to an embodiment of the present application. As shown in fig. 3, the set value of the second speed ramp parameter is β. When the second speed gradual change parameter beta is set to be 0, the intensity change speed at the end of the signal is consistent with the intensity change speed at the beginning of the signal, and the whole process is changed at a constant speed; when the second speed gradual change parameter beta is larger than 0, the change speed of the intensity at the end of the signal is smaller than the change speed of the intensity at the beginning of the signal (the larger beta is, the smaller the change speed of the intensity at the end of the signal is); when the second speed gradation parameter β is less than 0, the speed of change of the intensity at the end of the signal is larger than the speed of change of the intensity at the start of the signal (the smaller β, the larger the speed of change of the intensity at the end of the signal).
Further, based on the implementation of the above embodiment, in one implementation of step 130, only the vibration amplitude and the intensity variation speed at the signal start of the original signal need to be referred to. Therefore, in an application scenario according to one implementation of step 130, in the process of adjusting the initial signal of the original driving signal according to the initial intensity adjustment parameter to generate the first initial signal, after reading the original driving signal in the storage, the signal initial vibration amplitude of the original driving signal is amplified or reduced by s3Multiple, in the above process s3The value is the setting value of the intensity multiple in the initial intensity adjustment parameter.
Further, in one implementation manner of step 130, the process of calculating the first driving signal according to the user vibrotactile parameter and the original driving signal includes:
generating a weighted envelope line according to the initial intensity adjustment parameter, the intensity change parameter and the speed change parameter;
the weighted envelope is used to multiply the original drive signal to generate a first drive signal.
Fig. 5 is a flowchart illustrating a method for calculating a first driving signal according to an embodiment of the present application. As shown in fig. 5:
531, performing a multiplication operation on the weighted envelope curve p and the original driving signal U0 to obtain a first driving signal;
and 540, outputting the first driving signal.
Specifically, in one implementation of step 530, an envelope curve p is calculated, and the formula is as follows:
when beta is more than or equal to 0:
when β<At time 0:
in the above equations (1) and (2), T is a time variable, T is an original signal duration, s, α, and β are an input intensity multiple, a third amplitude gradient parameter, and a second speed gradient parameter, respectively, and p is a weighted envelope curve.
Fig. 6 shows a magnitude gradient envelope curve obtained by calculation according to an embodiment of the present application. In a specific application scenario, the obtained amplitude fade-in envelope calculated according to the above equations (1) and (2) is shown in fig. 6. In fig. 6, the abscissa represents time, and the ordinate represents intensity. The two curves indicated by reference numeral 601 represent that the amplitude of the vibration signal is gradually increased but the intensity change speed is gradually decreased; the curve indicated by reference numeral 602 indicates that the amplitude of the vibration signal is gradually increased but the intensity change speed is uniform; the two curves indicated by reference numeral 603 indicate that the amplitude of the vibration signal is gradually increased but the intensity change speed is gradually increased.
Fig. 7 is a waveform diagram of a first driving signal obtained by calculation according to an embodiment of the present application. In a specific application scenario, the first driving signal obtained by calculation according to an embodiment of the present application is shown in fig. 7. In fig. 7, the abscissa represents time, and the ordinate represents the voltage signal intensity of the drive signal. As shown in fig. 7, the amplitude of the drive signal fades up.
Further, in an embodiment of the present application, the user vibration touch parameters are customized by the user. Specifically, in one implementation of step 110, an interactive interface for inputting vibrotactile parameters of a user is provided, and the vibrotactile parameters of the user of the first user are determined according to the input data of the first user.
For example, a display interface as shown in fig. 3 or fig. 4 is provided, and the user can input the α or β parameter value by selecting the position corresponding to the parameter α or β on the interface as shown in fig. 3 or fig. 4.

Further, in the 90 s of the 20 th century, improvements in a technology could clearly distinguish between improvements in hardware (e.g., improvements in circuit structures such as diodes, transistors, switches, etc.) and improvements in software (improvements in process flow). However, as technology advances, many of today's process flow improvements have been seen as direct improvements in hardware circuit architecture. Designers almost always obtain the corresponding hardware circuit structure by programming an improved method flow into the hardware circuit. Thus, it cannot be said that an improvement in the process flow cannot be realized by hardware physical modules. For example, a Programmable Logic Device (PLD), such as a Field Programmable Gate Array (FPGA), is an integrated circuit whose Logic functions are determined by programming the Device by an accessing party. A digital device is "integrated" on a PLD by the designer's own programming without requiring the chip manufacturer to design and fabricate a dedicated integrated circuit chip. Furthermore, nowadays, instead of manually making an Integrated Circuit chip, such programming is often implemented by "logic compiler" software, which is similar to a software compiler used in program development and writing, but the original code before compiling is also written by a specific programming Language, which is called Hardware Description Language (HDL), and HDL is not only one but many, such as abel (advanced Boolean Expression Language), ahdl (alternate Language Description Language), traffic, pl (core unified programming Language), HDCal, JHDL (Java Hardware Description Language), langue, Language, HDL, las, software, Hardware Description Language, and so on. It will also be apparent to those skilled in the art that hardware circuitry that implements the logical method flows can be readily obtained by merely slightly programming the method flows into an integrated circuit using the hardware description languages described above.
The controller may be implemented in any suitable manner, for example, the controller may take the form of, for example, a microprocessor or processor and a computer-readable medium storing computer-readable program code (e.g., software or firmware) executable by the (micro) processor, logic gates, switches, an Application Specific Integrated Circuit (ASIC), a programmable logic controller, and an embedded microcontroller, examples of which include, but are not limited to, the following microcontrollers: ARC 625D, Atmel AT91SAM, Microchip PIC18F26K20, and Silicone Labs C8051F320, the memory controller may also be implemented as part of the control logic for the memory. Those skilled in the art will also appreciate that, in addition to implementing the controller as pure computer readable program code, the same functionality can be implemented by logically programming method steps such that the controller is in the form of logic gates, switches, application specific integrated circuits, programmable logic controllers, embedded microcontrollers and the like. Such a controller may thus be considered a hardware component, and the means included therein for performing the various functions may also be considered as a structure within the hardware component. Or even means for performing the functions may be regarded as being both a software module for performing the method and a structure within a hardware component.
