Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, a cursor moving method according to a first embodiment of the present invention is applied to an intelligent terminal, where the intelligent terminal at least includes an acceleration sensor, and the intelligent terminal may be a smart phone or a smart tablet, such as a touch-control smart phone of a common Android system or IOS system, and in this embodiment, the method is described by taking the smart phone as an example, and includes:
s101, when the intelligent terminal is in a text editing mode, receiving acceleration which is obtained by the acceleration sensor and generated when a user shakes the intelligent terminal;
when the smart phone is in a text editing mode, for example, when a text in a notepad is edited, a certain position in the text appears on a cursor, at this time, a user can shake the smart phone, and a processor of the smart phone starts to monitor data of an acceleration sensor of the smart phone to acquire acceleration generated when the user shakes the smart terminal, so that shake detection is realized.
S102, judging whether a preset cursor movement rule is met or not according to the direction and the magnitude of the acceleration;
specifically, the acceleration obtained by the acceleration sensor includes magnitude and direction, for example, the magnitude of the acceleration is 5m/s2The direction is horizontal to left, a preset cursor movement rule can be stored in the smart phone in advance, and accelerations in different directions and magnitudes correspond to different cursor movement rules, for example, the magnitude is 5m/s2And the cursor movement rule corresponding to the acceleration with the direction of horizontal left is to move the cursor to the middle of the current text, and then judge whether the current acceleration accords with the preset cursor movement rule or not according to the current acceleration acquired by the acceleration sensor.
And S103, if so, moving the cursor according to a cursor movement rule corresponding to the direction and the magnitude of the acceleration.
If the current acceleration conforms to the preset cursor movement rule, for example, the magnitude is 5m/s2And the direction is horizontal leftward acceleration which accords with a preset cursor movement rule, and at the moment, the cursor is moved according to the corresponding cursor movement rule, namely, the cursor is moved to the middle of the current text. It can be understood that if the current acceleration does not conform to the preset cursor movement rule, for example, the magnitude is 0.8m/s2And if the acceleration is not in accordance with the preset cursor movement rule, the cursor movement operation cannot be carried out if no corresponding cursor movement rule exists.
According to the cursor moving method provided by the embodiment of the invention, when a user edits a text by using the intelligent terminal, the user only needs to shake the intelligent terminal, the acceleration generated when the user shakes the intelligent terminal is acquired by receiving the acceleration sensor in the intelligent terminal, and then the cursor is moved according to the cursor moving rule corresponding to the direction and the magnitude of the acceleration, so that the cursor is moved to the corresponding position in the text, the cursor is more conveniently positioned, and the existing intelligent terminal is provided with the acceleration sensor, so that the hardware cost is not required to be additionally increased.

9. The cursor movement system of claim 6, wherein the movement module is specifically configured to:
judging whether the last line feed character closest to the current position of the cursor exists or not;
if yes, moving the cursor to the position of the previous character of the nearest previous line feed character;
if not, moving the cursor to the text header of the current text;
the mobile module is further configured to:
judging whether a next line feed character closest to the current position of the cursor exists or not;
if so, moving the cursor to the position of the nearest next line break character;
and if not, moving the cursor to the text tail of the current text.
10. The cursor movement system of claim 8, wherein the movement module is further configured to:
searching for the position pos1 of the last line break closest to the current position of the cursor and the position pos2 of the next line break closest to the current position of the cursor;
and moving the cursor to a position of (pos1+ pos2)/2, wherein pos1 is 0 when a last line break closest to the current position of the cursor does not exist, and pos2 is the total length of the current text when a next line break closest to the current position of the cursor does not exist.
