Processing method for touch operation and terminal

1. A method of processing a touch operation, comprising:

receiving a touch operation of a user, and determining coordinates of a touch point;

selecting a touch object of touch objects as a touch operation object in response to the touch operation of the user and further in response to the coordinates of the touch point being located in a touch region corresponding to the touch object;

determining a calculation region according to the coordinates of the touch point in response to the coordinates of the touch point not being located in a touch region of the touch objects, wherein a display interface is divided into a plurality of regions having a same shape and size, and wherein the determining the calculation region comprises selecting the region of the plurality of regions where the touch point falls as the calculation region;

calculating, in response to the coordinates of the touch point not being located in a touch region of the touch objects, a distance between the touch point and a touch region of each of the touch objects in the calculation region according to the coordinates of the touch point and without calculating a distance to at least one touch region outside of the calculation region, wherein the touch region of each of the touch objects is a region larger than the respective touch object and that extends in two dimensions and is bounded by a border, wherein the border of each touch region is spaced apart from the border of each adjacent touch region, and wherein the distance between the touch point and the respective touch region of each of the touch objects is a shortest straight line distance to a nearest point on the border of the respective touch region; and

selecting, as a touch operation object, a touch object corresponding to the minimum value among the distances in response to the coordinates of the touch point not being located in a touch region of the touch objects.

2. The method according to claim 1 ,

wherein the calculation region is smaller than a display interface.

3. The method according to claim 2 , wherein the method further comprises: selecting a touch object as the touch operation object after the determining coordinates of the touch point and when the coordinates of the touch point locate in the touch region of the touch object.

4. The method according to claim 1 , wherein the calculation region is rectangular and larger than each of the touch regions.

5. A terminal, comprising:

a touchscreen;

a touch point coordinate determination unit configured to receive a touch operation of a user on the touchscreen, and to determine coordinates of a touch point on the touch screen;

a second touch operation object selection unit configured to select a touch object of touch objects as a touch operation object in response to the receiving the touch operation of the user and further in response to the coordinates of the touch point being located in a touch region corresponding to the touch object;

a calculation region determination module configured to determine a calculation region according to the coordinates of the touch point in response to the coordinates of the touch point not being located in a touch region of the touch objects, the calculation region having a preset dimension;

a distance calculation unit configured to calculate, in response to the coordinates of the touch point not being located in a touch region of the touch objects in the calculation region, a distance between the touch point and a touch region of each of the touch objects according to the coordinates of the touch point and without calculating a distance to at least one touch region outside of the calculation region, wherein the touch region of each of the touch objects is a region larger than the respective touch object and that extends in two dimensions of the touchscreen, wherein the touch region of each of the touch objects is bounded by a respective border, wherein the border of each touch region is spaced apart from the border of each adjacent touch region, and wherein the distance between the touch point and the respective touch region of each of the touch objects is a shortest straight line distance to a nearest point on the border of the respective touch region; and

a first touch operation object selection unit configured to select a touch object corresponding to the minimum value among the distances as a touch operation object in response to the coordinates of the touch point not being located in a touch region of the touch objects.

6. The terminal according to claim 5 ,

wherein the calculation region is smaller than a display interface of the touchscreen.

7. The terminal according to claim 6 , further comprising a second touch operation object selection unit configured to select a touch object as the touch operation object when the coordinates of the touch point locate in the touch region of the touch object.

8. The terminal according to claim 5 , wherein the calculation region is rectangular and larger than each of the touch regions, and wherein the preset dimension is a preset side length of a side of the calculation region.

9. A terminal, comprising:

a touchscreen;

a processor connected to the touchscreen; and

a non-transitory computer readable medium connected to the processor and having stored thereon instructions that, when executed, cause the processor to:

receive a touch operation of a user on the touchscreen, and to determine coordinates of a touch point on the touchscreen;

select a touch object of touch objects as a touch operation object in response to the touch operation of the user and further in response to the coordinates of the touch point being located in a touch region corresponding to the touch object;

determine a calculation region according to the coordinates of the touch point in response to the coordinates of the touch point not being located in a touch region of the touch objects, the calculation region having a preset dimension, wherein a display interface is divided into a plurality of regions having a same shape and size, and wherein the calculation region is a region of the plurality of regions where the touch point falls; and

calculate, in response to the coordinates of the touch point not being located in a touch region of the touch objects, a distance between the touch point and a touch region of each of the touch objects in the calculation region according to the coordinates of the touch point and without calculating a distance to at least one touch region outside of the calculation region, wherein the touch region of each of the touch objects is a region larger than the respective touch object and that extends in two dimensions of the touchscreen, wherein the touch region of each of the touch objects is bounded by a respective border, wherein the border of each touch region is spaced a part from the border of each adjacent touch region, and wherein the distance between the touch point and the respective touch region of each of the touch objects is a shortest straight line distance to a nearest point on the border of the respective touch region; and

select a touch object corresponding to the minimum value among the distances as a touch operation object in response to the coordinates of the touch point not being located in a touch region of the touch objects.

10. The terminal according to claim 9 ,

wherein the calculation region is smaller than a display interface of the touchscreen.

11. The terminal according to claim 10 , wherein the non-transitory computer readable medium further has stored thereon instructions that, when executed, cause the processor to:
