Embodiment Construction

[0026] Embodiments of the tactile feedback method and its electronic device are disclosed below. In some embodiments, tactile feedback related to image content can be provided, so as to improve the operation convenience of the electronic device. The provision of tactile feedback can reduce the user's reliance on vision and increase user experience. Moreover, it can also improve the problem of poor tactile feedback in a simple touch operation, thereby improving the operation convenience of the electronic device.

[0027] Please refer to figure 1 , which shows a flowchart of a tactile feedback method executed by an electronic device according to an embodiment of the present invention. This control method includes several steps. In step S110, an original image is acquired. In step S120, the original image is converted into a binary image. The binary image includes a first gray value and a second gray value. In step S130, the original image is converted into a grayscale imag...

Abstract

A method and an electronic device for tactile feedback are provided. The tactile feedback comprises a plurality of steps. An original image is input and converted to a binary image which includes a first grayscale value and a second grayscale value. The original image is converted to a grayscale image at least including a third grayscale value between the first grayscale value and the second grayscale value. An index map is generated according to the binary image and the grayscale image. The index map includes a plurality of index values indicative of different strengths for tactile feedback. A touch input on a touch panel is detected when the original image is displayed on a display panel. In response to the detected touch input, a tactile activation unit is driven to generate tactile feedback according to the index map.

Description

technical field [0001] The present invention relates to a tactile feedback method and its electronic device, and in particular to a tactile feedback method for responding to touch input and its electronic device. Background technique [0002] With the vigorous development of touch sensing technology, more and more electronic devices begin to use touch display screens. The touch display screen can provide visual feedback and allow the user to operate the electronic device by means of touch input. [0003] Compared with general user interfaces such as keyboards or buttons of electronic devices, the tactile feedback of touch-sensitive display screens is poor. In more detail, when the user performs touch input, the fingertip or stylus can hardly feel the contact feeling, which makes it difficult for the user to know whether the touch input is completed correctly or not to know the touch input. how many times. Therefore, the user needs to rely on the visual feedback provided b...
