Electronic device, method of operating the same, and computer-readable medium that stores a program

A method of operating an electronic device that includes a flexible touch-screen unit and a body unit to which the flexible touch-screen unit is attached, the method comprising:

• determining that a first user command is input when a border between a flat surface touch-screen region and a curved surface touch-screen region of the flexible touch-screen unit is traversed from a first direction;
• and
• determining that a second user command is input when the border between the flat surface touch-screen region and the curved surface touch-screen region is traversed from a second direction, the second direction being opposite to the first direction.

A computer-readable medium that stores a program for operating an electronic device that includes a flexible touch-screen unit and a body unit to which the flexible touch-screen unit is attached, wherein the program implements a function of determining that a first user command is input when a border between a flat surface touch-screen region and a curved surface touch-screen region of the flexible touch-screen unit is traversed from a first direction, and a function of determining that a second user command is input when the border between the flat surface touch-screen region and the curved surface touch-screen region is traversed from a second direction, the second direction being opposite to the first direction.
