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

An electronic device comprising:

• a body unit;
• and
• a touch-screen unit comprising a touch-screen display device, the touch-screen unit being attached to the body unit and having at least one pair of facing curved sides,
• the touch-screen unit being configured to change a scroll speed in response to a touch-scroll operation performed on respective points of only the touch-screen display device of the touch-screen unit, and
• the scroll speed being based on the touch-scroll operation performed at the respective points relative to the at least one pair of facing curved sides,
• wherein the at least one pair of facing curved sides comprises convex-shaped sides, the convex-shaped sides constituting a convex region of the touch-screen unit
• wherein the scroll speed in a parallel direction to the at least one pair of facing curved sides of the touch-screen unit decreases when the touch-scroll operation is performed toward a center part of the convex region of the touch-screen unit.

A method of operating an electronic device, the method comprising:

• performing a touch-scroll operation on only a touch-screen display device of a touch-screen unit having at least one pair of facing curved sides in response to a user input;
• and
• changing a scroll speed based on a location of the touch-scroll operation performed relative to the at least one pair of facing curved sides,
• wherein the at least one pair of facing curved sides comprises a left curved side and a right curved side of the touch-screen unit, or an upper curved side and a lower curved side of the touch-screen unit,
• wherein the at least one pair of facing curved sides comprises concave-shaped sides, the concave-shaped sides constituting a concave region of the touch-screen unit, and
• wherein the changing the scroll speed comprises:
• increasing the scroll speed in a parallel direction to the at least one pair of facing curved sides of the touch-screen unit in response to the touch-scroll operation being performed toward a center part of the concave region of the touch-screen unit;
• and
• decreasing the scroll speed in a cross direction to the at least one pair of facing curved sides of the touch-screen unit in response to the touch-scroll operation being performed toward the center part of the concave region of the touch-screen unit.
