Description

[0001] METHOD AND APPARATUS FOR EDITING TABLE ON ELECTRONIC DOCUMENT THROUGH TOUCH-SCREEN DISPLAY [0002]

The present invention relates to a method for editing an electronic document or the like, and more particularly, to a method and apparatus for inserting or deleting a matrix on a table on an electronic document through a touch screen display.

The touch screen display means a device capable of receiving a signal through a display by applying a minute current or pressure on the display. There is a point similar to a touch pad in that an input signal is applied through a touch sensor that recognizes a minute current or pressure. However, in the case of the touch pad, the pointer on the display moves according to the relative movement of the touch fan or the finger input on the touch pad, while in the case of the touch screen display, the touch sensor and the touch pad are implemented together to apply a signal to a specific point on the display The difference is that the pointer works at that point. Therefore, it is very important to recognize the sensitivity of a touch screen when a signal is applied to the touch screen through a finger or the like. Recently, a capacitive touch screen display having excellent response to an input signal has been developed, and various functions that can be performed through a touch screen display in an electronic device are being developed. The user does not need a separate input device because the user usually makes a selection on the display screen by pointing the GUI object directly on the display screen with the stylus pen or the finger. Because of this advantage, it is widely used in mobile devices, and since the use of mobile devices equipped with the mobile devices has become commonplace, many of programs that have been performed through computers have been implemented through mobile devices. Designing a user interface that allows users to interact easily has become a new challenge.

In this regard, the conventional user interface on the touch screen display did not provide a simple and intuitive way to edit the document. For example, in order to insert a matrix into a table according to the related art, a menu has to be displayed at a position to be inserted, a menu to be inserted must be selected, and a position to be inserted has to be selected. In addition, when a matrix is to be deleted, a row or column to be deleted is selected, a menu is opened, and a delete menu is selected. This has been a huge inconvenience, especially for users who want to insert or delete multiple rows or columns, forcing multiple menu selections. Thus, in editing tables on electronic documents, there has been a need to develop a method and apparatus that can reduce the perceived burden on a user of a device with a touch screen display and provide a more efficient interface.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a table editing method and apparatus for editing a table on an electronic document, which can reduce the burden of the user's perception through the touch screen display and assist in efficient electronic document creation.
