Abstract

According to one embodiment, an electronic apparatus includes a display controller, a detector and a processor. The display controller displays a document on a screen of a touch screen display, the document including one or more elements corresponding to a first layer and one or more elements corresponding to a second layer. The detector is configured to detect a position and a contact pressure of a first contact on the screen. The processor is configured to delete either a first element corresponding to the first layer or a second element corresponding to the second layer, by using the position and the contact pressure of the first contact.

Claims

1. An electronic apparatus comprising:

a display controller configured to display a document on a screen of a touch screen display, the document comprising one or more elements corresponding to a first layer and one or more elements corresponding to a second layer;

a detector configured to detect a position and a contact pressure of a first contact on the screen; and

a processor configured to delete either a first element corresponding to the first layer or a second element corresponding to the second layer, by using the position and the contact pressure of the first contact.

2. The electronic apparatus of claim 1, wherein the processor is configured to:

select either deleting the one or more elements corresponding to the first layer or deleting the one or more elements corresponding to the second layer, by using the contact pressure of the first contact; and

specify which one of one or more elements corresponding to a selected layer to be deleted, by using the position of the first contact.

3. The electronic apparatus of claim 2, wherein when the first layer is positioned in front of the second layer, and when the contact pressure of the first contact is greater than a threshold, the processor is configured to select deleting the one or more elements corresponding to the second layer.

4. The electronic apparatus of claim 3, wherein

the first layer corresponds to one or more handwritten strokes;

the second layer corresponds to one or more objects; and

the processor is configured to;

when the contact pressure of the first contact is not greater than a threshold, select deleting the one or more handwritten strokes corresponding to the first layer, and delete a first stroke of the one or more handwritten strokes by using the position of the first contact; and

when the contact pressure of the first contact is greater than the threshold, select deleting the one or more objects corresponding to the second layer, and delete a first object of the one or more objects by using the position of the first contact.

5. The electronic apparatus of claim 1, wherein the processor is configured to select either deleting the one or more elements corresponding to the first layer or deleting the one or more elements corresponding to the second layer, by using the contact pressure of the first contact, and to report the one or more elements selected to be deleted.

6. The electronic apparatus of claim 1, wherein the processor is configured to select deleting the one or more elements corresponding to the first layer by using the contact pressure of the first contact, to delete the first element by using the position of the first contact, and to delete a third element of the one or more elements corresponding to the first layer by using a position of a second contact of sliding the first contact when the position and a contact pressure of the second contact are further detected and a difference between the contact pressure of the first contact and the contact pressure of the second contact is not greater than a threshold.

7. A method of processing document data by an electronic apparatus comprising:

displaying a document on a screen of a touch screen display, the document comprising one or more elements corresponding to a first layer and one or more elements corresponding to a second layer;

detecting a position and a contact pressure of a first contact on the screen; and

deleting either a first element corresponding to the first layer or a second element corresponding to the second layer, by using the position and the contact pressure of the first contact.

8. The method of claim 7, wherein the deleting comprises selecting either deleting the one or more elements corresponding to the first layer or deleting the one or more elements corresponding to the second layer, by using the contact pressure of the first contact, and

specifying which one of one or more elements corresponding to a selected layer to be deleted, by using the position of the first contact.

9. The method of claim 8, wherein when the first layer is positioned in front of the second layer, and when the contact pressure of the first contact is greater than a threshold, the deleting comprises selecting deleting the one or more elements corresponding to the second layer.

10. The method of claim 9, wherein

the first layer corresponds to one or more handwritten strokes;

the second layer corresponds to one or more objects; and

the deleting comprises;

when the contact pressure of the first contact is not greater than a threshold, selecting deleting the one or more handwritten strokes corresponding to the first layer, and deleting a first stroke of the one or more handwritten strokes by using the position of the first contact; and

when the contact pressure of the first contact is greater than the threshold, selecting deleting the one or more objects corresponding to the second layer, and deleting a first object of the one or more objects by using the position of the first contact.

11. The method of claim 7, further comprising selecting either deleting the one or more elements corresponding to the first layer or deleting the one or more elements corresponding to the second layer, by using the contact pressure of the first contact, and reporting the one or more elements selected to be deleted.

12. The method of claim 7, wherein the deleting comprises selecting deleting the one or more elements corresponding to the first layer by using the contact pressure of the first contact, deleting the first element by using the position of the first contact, and deleting a third element of the one or more elements corresponding to the first layer by using a position of a second contact of sliding the first contact when the position and a contact pressure of the second contact are further detected and a difference between the contact pressure of the first contact and the contact pressure of the second contact is not greater than a threshold.

13. A computer-readable, non-transitory storage medium having stored thereon a program which is executable by a computer, the program controlling the computer to execute functions of:

displaying a document on a screen of a touch screen display, the document comprising one or more elements corresponding to a first layer and one or more elements corresponding to a second layer;

detecting a position and a contact pressure of a first contact on the screen; and

deleting either a first element corresponding to the first layer or a second element corresponding to the second layer, by using the position and the contact pressure of the first contact.

14. The storage medium of claim 13, wherein the deleting comprises:

selecting either deleting the one or more elements corresponding to the first layer or deleting the one or more elements corresponding to the second layer, by using the contact pressure of the first contact; and

specifying which one of the one or more elements corresponding to a selected layer to be deleted, by using the position of the first contact.

15. The storage medium of claim 14, wherein when the first layer is positioned in front of the second layer, and when the contact pressure of the first contact is greater than a threshold, the deleting comprises selecting deleting the one or more elements corresponding to the second layer.

16. The storage medium of claim 15, wherein

the first layer corresponds to one or more handwritten strokes;

the second layer corresponds to one or more objects; and

the deleting comprises;

when the contact pressure of the first contact is not greater than a threshold, selecting deleting the one or more handwritten strokes corresponding to the first layer, and deleting a first stroke of the one or more handwritten strokes by using the position of the first contact; and
