A device may include a touch-sensitive display, a memory to store a group of instructions, and a processor. The processor may execute the instructions in the memory to detect that a circular motion is being made on or near a surface of the touch-sensitive screen, detect a location on the touch-sensitive screen at which the circular motion is being made, and zoom in or zoom out on an item, being displayed on the touch-sensitive screen at the detected location, based on detecting that the circular motion is being made on or near the surface of the touch-sensitive screen. |
