Method and electronic device for tactile feedback
First Claim
1. A tactile feedback method for an electronic device, comprising:
- inputting an original image;
converting the original image to a binary image, the binary image comprising a first grayscale value and a second grayscale value;
converting the original image to a grayscale image, the grayscale image at least comprising a third grayscale value between the first grayscale value and the second grayscale value;
generating an index map according to the binary image and the grayscale image, the index map comprising a plurality of index values indicative of different strengths for tactile feedback;
detecting a touch input on a touch panel of the electronic device when the original image is displayed on a display panel; and
driving a tactile activation unit of the electronic device to generate tactile feedback according to the index map in response to the detected touch input.

Abstract
A method and an electronic device for tactile feedback are provided. 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.

8. An electronic device for tactile feedback, comprising:
-
a processing unit; a display panel, coupled to the processing module; a touch panel, coupled to the processing module and covered on the display panel; and a tactile activation unit, coupled to the processing module; wherein, the processing module receives an original image, and converts the original image to a binary image, the binary image comprising a first grayscale value and a second grayscale value;
the processing module further converts the original image to a grayscale image, the grayscale image at least comprising a third grayscale value between the first grayscale value and the second grayscale value;
the processing module further generates an index map according to the binary image and the grayscale image, the index map comprising a plurality of index values indicative of different strengths for tactile feedback;
the processing module further detects a touch input on the touch control panel when the original image is displayed on the display panel; and
the processing module further drives the tactile activation unit according to the index map to generate tactile feedback in response to the detected touch input. - View Dependent Claims (9, 10, 11, 12, 13, 14)
