Abstract: In one embodiment, a method for positioning a cursor displayed on a touch-sensitive display screen is provided. The method may comprise detecting a body member touching the touch-sensitive display screen and identifying an offset between the body member and the cursor. Movement of the body member relative to the touch-sensitive display screen can also be detected. Upon detection of the movement, the cursor is also moved from the offset to match the movement of the body member. The body member may then be released and repositioned to a different position on the touch-sensitive display screen. Upon detection of the repositioning, a different offset between the body member at the different position and the cursor is identified. Additional movement of the body member after the detection of the reposition is detected and thereafter, the cursor is moved from the different offset to match the additional movement of the body member.
