Abstract

An apparatus for measuring coordinates of input from an input means and a control method thereof are provided. The control method includes displaying a user input interface and receiving a user input from the input means, detecting an increase in a distance between the input means and the apparatus for measuring the coordinates, determining whether a hover event is completed, based on the distance between the input means and the apparatus for measuring the coordinates, and displaying a result of recognizing the user input as text when the hover event is completed.

Claims

1. A control method of an apparatus for measuring coordinates of an input by an input means, the control method comprising:

displaying a user input interface;

receiving a user input on the user input interface;

detecting an increase in a distance between the input means and the apparatus for measuring the coordinates;

comparing a preset length and the distance between the input means and the apparatus for measuring the coordinates in response to the detecting of the increase in the distance;

displaying the user input interface continuously, while the input means is placed at a position corresponding to a height equal to or less than the preset length;

determining whether a hover event is completed based on a result of the comparing of the preset length and the distance between the input means and the apparatus for measuring the coordinates;

determining whether a time period of maintaining the completion of the hover event exceeds a preset time period, in response to determining that the hover event is completed; and

based on the time period exceeding the preset time period, displaying a result of recognizing the user input as text.

2. The control method as claimed in claim 1, wherein the hover event occurs while the distance between the input means and the apparatus for measuring the coordinates is equal to or less than the preset length.

3. The control method as claimed in claim 2, wherein the determining of whether the hover event is completed comprises:

determining that the hover event is completed when a strength of a reception signal received from the input means is less than a preset strength.

4. The control method as claimed in claim 1, wherein the displaying of the result of recognizing the user input as the text comprises:

simultaneously performing text recognition on the user input; and

displaying a result of performing the text recognition.

5. The control method as claimed in claim 1, wherein the displaying of the result of recognizing the user input as the text comprises:

displaying the user input interface while performing text recognition on the user input even when the hover event is not completed.

6. The control method as claimed in claim 5, wherein the displaying of the result of recognizing the user input as the text comprises:

simultaneously displaying the result of recognizing the user input as the text.

7. The control method as claimed in claim 1, further comprising determining whether the user input is not entered after a preset time period, while the hover event occurs.

8. The control method as claimed in claim 7, wherein the hover event is determined to be completed when the user input is not entered after the preset time period.

17. A non-transitory computer-readable storage medium storing instructions that when executed cause at least one processor to perform the method of claim 1.

9. An apparatus for measuring coordinates of an input by an input means, the apparatus comprising:

a touch screen; and

a controller configured to;

control the touch screen to display a user input interface,

receive a user input on the user input interface,

perform a control operation so as to detect an increase in a distance between the input means and the apparatus for measuring the coordinates,

compare a preset length and the distance between the input means and the apparatus for measuring the coordinates in response to the detecting of the increase in the distance,

display the user input interface continuously, while the input means is placed at a position corresponding to a height equal to or less than the preset length,

determine whether a hover event is completed based on a result comparing of the preset length and the distance between the input means and the apparatus for measuring the coordinates,

determine whether a time period of maintaining the completion of the hover event exceeds a preset time period, in response to determining that the hover event is completed, and

perform a control operation so as to display a result of recognizing the user input as text, based on the time period exceeding the preset time period.

10. The apparatus as claimed in claim 9, wherein the hover event occurs while the distance between the input means and the apparatus for measuring the coordinates is equal to or less than the preset length.

11. The apparatus as claimed in claim 10, wherein the controller determines that the hover event is completed when a strength of a reception signal received from the input means is less than a preset strength.

12. The apparatus as claimed in claim 9, wherein the controller performs a control operation so as to simultaneously perform text recognition on the user input, and so as to display a result of performing the text recognition.

13. The apparatus as claimed in claim 9, wherein the controller performs a control operation so as to display the user input interface while performing text recognition on the user input even when the hover event is not completed.

14. The apparatus as claimed in claim 13, wherein the controller performs a control operation so as to simultaneously display the result of recognizing the user input as the text.

15. The apparatus as claimed in claim 9, wherein the controller determines whether the user input is not entered after a preset time period, while the hover event occurs.

16. The apparatus as claimed in claim 15, wherein the controller determines that the hover event is completed when the user input is not entered after the preset time period.
