【Detailed ways】

In order to make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the various embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, those of ordinary skill in the art can understand that, in each embodiment of the present invention, many technical details are proposed for the reader to better understand the present invention. However, even without these technical details and various changes and modifications based on the following embodiments, the technical solution claimed by the present invention can be realized.

Embodiments of the present invention provide a tactile feedback method, an electronic device, and a storage medium. A user performs a touch operation on a touch display component of the electronic device, and the electronic device sends specific driving information to drive the motor to vibrate, and the vibration feedback touches the image displayed by the display component Information, realize the combination of image information and motor vibration, and achieve customized, precise and diversified tactile feedback. Specifically, electronic devices include, but are not limited to, smart phones, tablet computers, and portable wearable devices.

Please refer to FIGS. 1 to 2. FIGS. 1 and 2 are respectively a schematic flowchart of a haptic feedback method and a schematic operation diagram of the method according to the first embodiment of the present invention. In this embodiment, the user can perform a touch operation on the image displayed on the touch display component 101 of the electronic device 100 to obtain vibration feedback of the motor. As shown in Figure 1, the tactile feedback method includes:

Step S101: detecting a touch operation in the touch display component;

The touch display component 101 is used to display an image of the electronic device 100, and the user can touch the image on the touch display component 101 with a finger. In this embodiment, the touch operation is tapping and clicking an image, long-pressing the image, or long-pressing and dragging the image.

Step S103: when a touch operation is detected, obtain coordinate information of the corresponding touch position;

The user performs a touch operation on the image on the touch display component 101, and the coordinate information is the coordinate position on the touch display component 101 where the electronic device 100 detects the touch operation.

Step S105: Obtain image parameters of the corresponding analytical image according to the coordinate information;

The resolved image is an image displayed on the touch display component. The image parameter is obtained by analyzing the image information of the analyzed image. Specifically, the image parameter may include one or both of the color value and the brightness value of the pixels constituting the analytical image. Wherein, the color value is the color value of the pixel of the image displayed by the touch display component 101, and is the color value corresponding to a color in different color modes. Specifically, the color mode may be one of RGB mode, CMYK mode, HSB mode, Lab color mode, bitmap mode, grayscale mode, indexed color mode, duotone mode, and multi-channel mode. The brightness value is the brightness of the pixels of the image displayed by the touch display component 101. Specifically, the brightness value of the pixel is between 0 and 255.

Step S107: Calculate driving signal parameters according to the image parameters;

By obtaining the color value and brightness value of the analytical image, the driving signal parameter can be calculated according to the color value of the analytical image, or the driving signal parameter can be calculated according to the brightness value; or combined with the color value and brightness value of the analytical image, the driving signal parameter can be calculated. The driving signal parameter is used to control the vibration feedback of one or more of the vibration frequency, amplitude, and vibration duration of the motor. It is understandable that the different color values, different brightness values, or combinations of different color values and brightness values of the image are analyzed, and different driving signal parameters are calculated correspondingly, and the motor is controlled to give different modes of vibration feedback.

Step S109: Generate a drive signal and drive the motor to vibrate according to the drive signal parameter.

The motor drive module converts the drive signal parameters into drive signals, and drives the motor to complete the vibration mode preset by the drive signal parameters.

In the foregoing embodiment, the image parameters of the image are analyzed to calculate the corresponding driving signal parameters to drive the motor to perform different vibration feedback. Diversify the user experience when operating electronic devices.

The present invention also includes a second embodiment. The difference between the second embodiment and the first embodiment is that before calculating the driving signal parameters according to the image parameters, the second embodiment further includes:

Step S201: Determine whether the image parameters meet preset conditions;

Step S203: If the image parameter meets the preset condition, calculate the corresponding driving signal parameter according to the image parameter.

In this embodiment, after obtaining the image parameters of the corresponding analysis image, it is determined whether the brightness value and the color value of the image meet the preset conditions.

In some embodiments, the preset condition is a preset color value, and the specific steps are as follows:

Step S2011: Determine whether the color value of the image parameter meets the preset color value.

If the color value of the image parameter meets the preset color value, step S107 is performed, that is, the corresponding driving signal parameter is calculated according to the image parameter.

For example, the preset color value is RGB value, the value is 25, 25, 112, when the RGB value of the image parameter of the touch operation position is 25, 25, 112, it is judged that the image parameter meets the preset condition, and the corresponding driving signal parameter is obtained .

In other embodiments, the preset condition is a preset brightness value, and the specific steps are as follows:

Step S2021: Determine whether the brightness value of the image parameter meets the preset brightness value.

If the brightness value of the image parameter meets the preset brightness value, step S107 is performed, that is, the corresponding driving signal parameter is calculated according to the image parameter.

For example, the preset condition sets the brightness value of the image parameter to be greater than 100, and when the brightness value of the image parameter at the touch operation position is 120, it is determined that the image parameter meets the preset condition, and the corresponding driving signal is obtained. In some embodiments, the preset condition is a specific brightness value. For example, if the preset condition is an image parameter with a brightness value of 120, then when the brightness value of the image parameter at the touch operation position is 120, the preset condition is met. , The drive signal parameters can be calculated according to the corresponding image parameters.

In other embodiments, the preset condition includes a preset color value and a preset brightness value. The specific steps are as follows:

Step S2031: If the color value of the image parameter meets the preset color value, continue to determine whether the brightness value of the image parameter meets the preset brightness value.

If the identified brightness value meets the preset brightness value, and it is determined that the image parameter of the touch operation position meets the preset condition, step S107 is performed, that is, the corresponding driving signal parameter is calculated according to the image parameter.

For example, the preset color value is RGB value, the value is 25, 25, 112, and the preset brightness value is above 100. When the RGB value of the image parameter of the touch operation position is 25, 25, 112, and the brightness value of the image parameter is 120, which meets the preset condition, the driving signal parameter can be calculated according to the corresponding image parameter.

In some embodiments, the analytical image may be a mapped image of an image displayed by the touch display component 101, and the mapped image is a virtual image that is not displayed on the touch display component 101. For example, when the image displayed by the touch display component 101 is complicated and the corresponding image information is large, a relatively simple mapped image can be used as an analytical image instead of the image displayed by the touch display component 101. It should be noted that the mapping image has the same size and resolution as the display image having the same coordinate information on the touch display component 101. The mapped image can be set with specific image parameters as required. When the user touches the display image, the corresponding driving signal parameters can be calculated through the image parameters of the mapped image of the display image.

Please refer to FIG. 3, which is a partial flowchart of the third embodiment. The difference between the third embodiment and the first embodiment is that, before detecting the touch operation in the touch display component, it further includes:

Step S301: Analyze the image for pre-analysis to obtain the image parameters of each pixel and the coordinate information of each pixel in the touch display component.

Step S303: Associate and store the image parameters of each pixel and the coordinate information.

In this embodiment, the image displayed by the touch display component 101 or the mapped image of the displayed image is analyzed in advance, and the image parameters obtained by the analysis are associated with coordinate information and stored. When the user performs a touch operation on any display image of the touch display component 101, the image parameters corresponding to the coordinate information of the touch operation can be directly used to calculate the driving signal parameters. By pre-analyzing the analytical image, the step of analyzing the analytical image of the electronic device when the user performs a touch operation is eliminated, the calculation process of the electronic device can be reduced, and the touch feedback processing process can be simplified.

The above implementation examples combine the vibration of the motor with the displayed image to achieve the purpose of customizable, precise, and diversified tactile feedback, increase the freedom of setting the electronic device 100, and make the technology more humane.
