Abstract

A touch region adjustment method includes: determining a region on a touch display of a terminal device and in which a sensing parameter changes to determine a grasping gesture of a user for the terminal device; and adjusting a location of a touch response region on the touch display based on the grasping gesture of the user for the electronic device to avoid an accidental touch caused by the grasping gesture of the user for the screen of the terminal device.

First claim

What is claimed is:

1. A touch region adjustment method implemented by an electronic device, wherein the touch region adjustment method comprises:
receiving, on a touchscreen of the electronic device, a first touch input;
determining a first contact surface of the first touch input, wherein the first contact surface is located on a side screen on the touchscreen;
obtaining first touch information of the first contact surface, wherein the first touch information comprises capacitance information and one or more of a first height of the first contact surface, a first width of the first contact surface, or an area of the first contact surface;
determining, based on the first touch information, a touch region and a first non-touch region on the side screen, wherein a first distance between the touch region and the first contact surface comprises a first distance value, and wherein the first non-touch region comprises the first contact surface;
determining that the touch region is located between a first end of the side screen and the first contact surface when a second distance between the first contact surface and the first end is greater than or equal to a first preset value;
determining that a type of the first contact surface is a thenar contact surface when the first touch information meets a first preset condition, wherein the first preset condition comprises that:
the first height is greater than a first height threshold and a first ratio of a first capacitance value of a most edge coordinate column of the first contact surface to a second capacitance value of a secondary edge coordinate column of the first contact surface is within a first ratio range, wherein a first value in the first ratio range is greater than or equal to 1, wherein the most edge coordinate column is closest to a long side of the electronic device and in a touchscreen array corresponding to the first contact surface on the touchscreen, and wherein the secondary edge coordinate column is second closest to the long side and in the touchscreen array;
the first height is greater than the first height threshold, a second ratio of the first height to the first width is greater than a first height ratio, and the first ratio is within the first ratio range; or
the second ratio is greater than the first height ratio, the area is greater than a first area threshold, and the first ratio is within the first ratio range;

receiving, on the touch region, a second touch input;
displaying, in response to the second touch input, a first user interface;
receiving, on the first non-touch region, a third touch input; and
skipping changing, in response to the third touch input, display content on the electronic device.

2. The touch region adjustment method of claim 1 , wherein a region other than the touch region on the side screen is the first non-touch region.

3. The touch region adjustment method of claim 1 , further comprising:
determining a second contact surface of the first touch input located on the side screen before determining the touch region and the first non-touch region;
obtaining second touch information of the second contact surface before determining the touch region and the first non-touch region; and
further determining, based on the second touch information, the touch region and the first non-touch region on the side screen, wherein a third distance between the touch region and the second contact surface comprises the first distance value, wherein the first touch information further comprises one or more of the first height of the first contact surface, the first width of the first contact surface, or a first area of the first contact surface, wherein the second touch information comprises one or more of a second height of the second contact surface, a second width of the second contact surface, or a second area of the second contact surface, and wherein a region other than the touch region on the side screen is the first non-touch region.

4. The touch region adjustment method of claim 1 , wherein the first contact surface is located on a rear screen of the electronic device, and wherein the touch region adjustment method further comprises:
identifying that a third distance between a first side of the first contact surface and a top of the side screen is greater than or equal to a second preset value, wherein the first side is adjacent to the side screen, wherein a fourth distance between the first contact surface and the first side comprises the first distance value, and wherein a region other than the touch region on the side screen is the first non-touch region; and
determining, in response to identifying that the third distance is greater than or equal to the second preset value, that the touch region on the side screen is located between the top and the first side.

5. The touch region adjustment method according to claim 1 , wherein the first end is either a top of the side screen or a bottom of the side screen.

6. The touch region adjustment method of claim 1 , wherein after determining the touch region and the first non-touch region, the touch region adjustment method further comprises:
receiving, on the touchscreen, a fourth touch input;
determining a second contact surface of the fourth touch input located on the side screen;
obtaining second touch information of the second contact surface, wherein the second touch information comprises one or more of a second height of the second contact surface, a second width of the second contact surface, or an area of the second contact surface;
determining, based on the second touch information, that the side screen is a second non-touch region;
receiving, on the side screen, a fifth touch input; and
skipping changing, in response to the fifth touch input, the display content.

7. The touch region adjustment method of claim 6 , further comprising:
determining a third contact surface of the fourth touch input before determining that the side screen is the second non-touch region, wherein the third contact surface is located on the side screen;
obtaining third touch information of the third contact surface before determining that the side screen is the second non-touch region; and
further determining, based on the third touch information, that the side screen is the second non-touch region.

8. The touch region adjustment method of claim 1 , further comprising:
further determining that the type is a finger grasping contact surface when the first touch information meets a second preset condition; and
further determining that the touch region is located between the first end and the first contact surface when the second distance is greater than or equal to a second preset value,
wherein the first contact surface comprises a finger grasping contact surface closest to the first end,
wherein the second preset condition comprises that:
the first height is within a first height range and the first ratio is within a second ratio range, wherein a second value in the first height range is less than or equal to the first height threshold, wherein a third value in the second ratio range is greater than or equal to 1, and wherein the third value is greater than or equal to the first value;
the first height is within the first height range, the second ratio is within a third ratio range, and the first ratio is within the second ratio range, wherein a fourth value in the third ratio range is less than or equal to the first height ratio; or
the second ratio is within the third ratio range, the area is within a first area range, and the first ratio is within the second ratio range, wherein a fifth value in the first area range is less than or equal to the first area threshold.
