Abstract

A cursor control method and cursor control device of a smart TV, wherein when a character inputting box in a character inputting interface is in a non-editing state, the method includes the following steps: receiving and resolving a control signal from a remote control; triggering the character inputting box into an editable state if the control signal instructs to move the cursor into the character inputting box; judging whether a string exists in the character inputting box; if the judgement result is yes, judging a target position in the string where an input error may exist; and positioning the cursor at the target position in the string. The cursor control method and cursor control device of a smart TV in the present disclosure can make modification of strings existed in the character inputting box is more convenient, thereby improving modification efficiency and saving input operation cost for users.

Claims

1. A cursor control method of a smart TV, characterized in that, when a character inputting box in a character inputting interface is in a non-editing state, said method comprises:

receiving and resolving a control signal from a remote control;

triggering said character inputting box into an editable state if the control signal instructs to move a cursor into said character inputting box;

judging whether a string exists in said character inputting box;

performing error positioning on the string in said character inputting box if the judgement result is yes, thus determining a target position in said string where an input error may exist; and

positioning said cursor at said target position in the string.

2. The cursor control method according to claim 1, characterized in that, the method further comprises:

positioning said cursor at the forefront end in said character inputting box if the judgment result is no.

3. The cursor control method according to claim 1, characterized in that, said performing error positioning on the string in the character inputting box further comprises:

determining a string type of said string in said character inputting box according to a preset feature of a certain string type; and

performing error positioning on said string according to said error positioning feature corresponding to respective preset string type.

4. The cursor control method according to claim 3, characterized in that, before positioning said cursor at said target position in said string, the method further comprises:

providing a prompt of the information about said target position obtained from the error positioning to a user and asking said user whether it is necessary to move said cursor to said target position; and

triggering an operation of displaying said cursor at said target position in the string if a confirmation message is received from said user.

5. The cursor control method according to claim 3, characterized in that, said performing error positioning on said string contained in said character inputting box further comprises:

determining that the right side of the last character in said string is said target position.

6. The cursor control method according to claim 1, characterized in that, said control signal is triggered by a key on said remote control or triggered by a touch screen of said remote control.

7. A smart TV, characterized in that, an initial state of a character inputting box in a character inputting interface is in a non-editing state,

said smart TV comprises:

a memory having instructions stored thereon;

a processor configured to execute the instructions to perform operations of cursor control, comprising;

receiving and resolving a control signal from a remote control;

triggering said character inputting box into an editable state if the control signal instructs to move a cursor into said character inputting box;

judging whether a string exists in said character inputting box;

performing error positioning on said string in said character inputting box if the judgement result is yes, thereby determining a target position in said string where an input error may exist; and

positioning said cursor at said target position in said string.

8. The smart TV according to claim 7, characterized in that, the processor is further configured to perform:

determining module for determining a string type of said string in said character inputting box according to a preset feature of a certain string type; and

performing error positioning on the string according to the error positioning feature corresponding to respective preset string type.

9. The smart TV according to claim 8, characterized in that, the processor is further configured to perform:

providing a prompt of the information about said target position obtained from the error positioning to said user and asking said user whether it is necessary to move said cursor to said target position; and

triggering an operation of displaying said cursor at said target position in said string if a confirmation message is received from said user.

10. The smart TV according to claim 8, characterized in that, in the performing error positioning on said string in said character inputting box if the judgement result is yes, thereby determining a target position in said string where an input error may exist, the processor is further configured to perform:

determining that the right side of the last character in said string is said target position.

11. A non-transitory computer-readable recording medium having computer programs stored thereon that, when executed by one or more processors of a smart TV, cause the smart TV to perform:

receiving and resolving a control signal from a remote control;

triggering said character inputting box into an editable state if the control signal instructs to move a cursor into said character inputting box;

judging whether a string exists in said character inputting box;

performing error positioning on the string in said character inputting box if the judgement result is yes, thus determining a target position in said string where an input error may exist; and

positioning said cursor at said target position in the string.
