Abstract

A touch position locating method, text selecting method, device, and an electronic equipment. The touch position locating method including: acquiring position movement information from a gravity and acceleration sensor; calculating movement direction and distance of a cursor displayed on a touch screen according to the position movement information; and controlling a display position of the cursor according to the movement direction and distance of the cursor. The beneficial effect of the embodiments of the present invention is as follows: by swaying or slanting the electronic equipment having a touch screen, the display position of the cursor is controlled using the position movement information sensed by the gravity and acceleration sensor to accurately locate a point or select a text area, thereby improving the location accuracy of the touch screen and the user'"'"'s experience.

Claims

1. A touch position locating method, comprising:

acquiring position movement information from a gravity and acceleration sensor;

calculating movement direction and distance of a cursor displayed on a touch screen according to the position movement information; and

controlling a display position of the cursor according to the movement direction and distance of the cursor.

3. The method according to claim 1, wherein the position movement information comprises any combination of:

a movement direction;

a movement speed; and

a movement distance.

4. The method according to claim 1, wherein the cursor is a cross cursor, an arrow cursor or a blinking cursor.

2. A text selecting method, comprising:

determining an initial display position of a cursor displayed on a touch screen;

acquiring position movement information from a gravity and acceleration sensor;

calculating movement direction and distance of the cursor according to the position movement information;

determining a current display position of the cursor according to the movement direction and distance of the cursor; and

selecting a text of an area from the initial display position to the current display position as a target text.

11. The method according to claim 2, wherein the position movement information comprises any combination of:

a movement direction;

a movement speed; and

a movement distance.

12. The method according to claim 2, wherein the cursor is a cross cursor, an arrow cursor or a blinking cursor.

5. A touch position locating device, comprising:
