Method and system simplifying the input of symbols used as a pair within a user interface

An electronic device comprising:

• a display configured to:
• display an input window on a first region of a screen, the input window displaying a text input by a user, and
• display a first user interface on a second region of the screen, the first user interface being provided to select a symbol;
• and
• a processor configured to:
• receive a user input for selecting a first symbol through the first user interface,
• when a time period of the user input maintained through the first user interface is equal to or greater than a preset threshold value, determine the user input for selecting the first symbol as the first input event for inputting a text between the first symbol and the second symbol that is used as a pair with the first symbol and display the first symbol and the second symbol on the input window,
• when the time period of the user input maintained through the first user interface is less than the preset threshold value, determine the user input for selecting the first symbol as a second input event for displaying the first symbol on the input window, and
• change the first user interface displayed on the second region into a second user interface for inputting a text between the first symbol and the second symbol.

A non-transitory computer-readable recording medium having recorded thereon a program to be executed on a computer, the program configured to cause the computer to:

• display an input window on a first region of a screen of an electronic device, the input window displaying a text input by a user;
• display a first user interface on a second region of the screen, the first user interface being provided to select a symbol;
• receive a user input for selecting a first symbol through the first user interface;
• when a time period of the user input maintained through the first user interface is equal to or greater than a preset threshold value, determining the user input for selecting the first symbol as the first input event for inputting a text between the first symbol and the second symbol that is used as a pair with the first symbol and displaying the first symbol and the second symbol on the input window;
• when the time period of the user input maintained through the first user interface is less than the preset threshold value, determining the user input for selecting the first symbol as a second input event for displaying the first symbol on the input window;
• and
• change the first user interface displayed on the second region into a second user interface for inputting a text between the first symbol and the second symbol.
