Abstract

The present specification relates to a digital device and a method of controlling therefor. According to one embodiment, the digital device includes a touch sensitive display unit configured to detect a touch input, a transparent cover unit, which is positioned in an open position or a closed position and overlapped with the touch sensitive display unit in the closed position and a processor configured to control the touch sensitive display unit, the processor is further configured to detect the touch input on a first position of the touch sensitive display unit, when the transparent cover unit is in the open position, alter location information of the touch input detected on the first position to a second position, when the transparent cover unit is in the closed position, alter the location information of the touch input detected on the first position to a third position.

Claims

1. A digital device, comprising:

a touch sensitive display unit configured to detect a touch input;

a transparent cover unit, wherein the transparent cover unit is positioned in an open position or a closed position and is overlapped with the touch sensitive display unit in the closed position; and

a processor configured to control the touch sensitive display unit,

wherein the processor is further configured to;

detect the touch input on a first position of the touch sensitive display unit,

when the transparent cover unit is in the open position, alter location information of the touch input detected on the first position to a second position,

when the transparent cover unit is in the closed position, alter the location information of the touch input detected on the first position to a third position.

2. The digital device of claim 1, wherein a distance between the first position and the third position exceeds a distance between the first position and the second position.

3. The digital device of claim 1, wherein the processor is further configured to :

when the transparent cover unit is in the open position, detect the touch input of the first position by a first sensitivity, and

when the transparent cover unit is in the closed position, detect the touch input of the first position by a second sensitivity.

4. The digital device of claim 3, wherein the processor is further configured to set a sensitivity of the second touch sensitivity higher than the first touch sensitivity.

5. The digital device of claim 1, wherein the processor is further configured to detect a reference distance between a reference point of the touch sensitive display unit and the first position.

6. The digital device of claim 5, wherein a distance between the first position and the second position increases as the detected reference distance increases when the transparent cover unit is in the open position, and

wherein a distance between the first position and the third position increases as the detected reference distance increases when the transparent cover unit is in the closed position.

7. The digital device of claim 5, wherein the processor is further configured to:

when the first position and the altered second position are identical to each other and the first position and the altered third position are identical to each other, set the first position to the reference point.

8. The digital device of claim 5, wherein the processor is further configured to detect a gaze of a user positioned in front of the digital device,

wherein the reference point is set to a position where an angle between the digital device and the gaze of the user is within a threshold angle range, and

wherein the threshold angle range includes a right angle.

9. The digital device of claim 5, wherein the second position and the third position are positioned at a first direction based on the first position, and

wherein the first direction corresponds to a direction further apart from the reference point.

10. The digital device of claim 1, wherein the processor is further configured to detect an angle of a finger of a user touching the first position.

11. The digital device of claim 10, wherein a distance between the first position and the second position decreases as the detected angle of the finger of the user touching the first position increases when the transparent cover unit is in the open position, and

wherein a distance between the first position and the third position decreases as the detected angle of the finger of the user touching the first position increases when the transparent cover unit is in the closed position.

12. The digital device of claim 1, wherein the touch sensitive display unit is configured to display visual information.

13. The digital device of claim 12, wherein the processor is further configured to:

when the transparent cover unit is in the open position, control the visual information displayed in the second position with the touch input detected on the first position, and

when the transparent cover unit is in the closed position, control the visual information displayed in the third position with the touch input detected on the first position.

14. The digital device of claim 1, wherein the third position is set in proportion to a thickness of the transparent cover unit.

15. The digital device of claim 1, wherein the transparent cover unit corresponds to a touch sensitive transparent cover unit configured to detect a touch input.

16. The digital device of claim 15, wherein the processor is further configured to:

detect the touch input on a fourth position of the touch sensitive transparent cover unit using the touch sensitive transparent cover unit, and

alter location information of the touch input detected on the fourth position to a fifth position.

17. The digital device of claim 16, wherein the fourth position corresponds to the first position and is overlapped with the first position when the touch sensitive transparent cover unit is in the closed position.

18. The digital device of claim 17, wherein the processor is further configured to set a distance between the altered fifth position and the fourth position and a distance between the altered second position and the first position to be identical to each other.

19. The digital device of claim 17, wherein the processor is further configured to:

when the transparent cover unit is in the closed position, detect a touch input touching the fourth position for more than a threshold time using the touch sensitive display unit.

20. A method of controlling a digital device, comprising the steps of:

detecting a touch input on a first position of a touch sensitive display unit; and

altering for location information of the touch input detected on the first position,

wherein location information of the touch input detected on the first position is altered to a second position when a transparent cover unit is in an open position, and

wherein the location information of the touch input detected on the first position is altered to a third position when the transparent cover unit is in a closed position corresponding to a position that the transparent cover unit and the touch sensitive display unit overlap each other.
