A touch-sensitive display screen has at least two input modes for touch input. In an absolute input mode, positional information is interpreted in an absolute sense: an on-screen object or cursor can be moved, selected or activated by tapping or touching the screen at the location of the object itself or at a desired location for the object. In a relative input mode, touch input provided on the display screen is interpreted in a manner similar to a virtual joystick or a virtual touchpad. In the virtual joystick relative mode, input is interpreted relative to a reference point on the screen. In the virtual touchpad relative mode, input is interpreted according to a direction of motion of a contact point. |
