Patent Images
1. A method for precise multi-touch input, the method comprising:
- detecting, on a touchscreen, a first touch input at an approximate position of a first location;
displaying, in response to the first touch input, an input area on the touchscreen arranged so as not to overlap the location of the first touch input;
while the first touch input is maintained, detecting a second touch input at a second location within the displayed input area on the touchscreen;
detecting removal of the first touch input at the first location while the second touch input is maintained; and
adjusting the first location according to movement of the second touch input, such that the adjustment is less than and scaled to the movement of the second touch input,wherein the second location is any location sufficiently distant from the first location to prevent the movement of a finger associated with the second touch input at the second location from affecting a view of the first location.

13. An apparatus configured to provide a precise multi-touch input, the apparatus comprising:
-
a display; a touchscreen operatively coupled to the display and configured to detect a touch; and a processor configured to; detect, on a touchscreen, a first touch input at an approximate position of a first location, in response to detecting the first touch input, control the display to display an input area arranged so as not to overlap the location of the first touch input, detect a second touch input at a second location within the input area on the touchscreen while the first touch input is maintained, detect removal of the first touch input at the first location while the second touch input is maintained, and adjust the first location according to movement of the second touch input, such that the adjustment is less than and scaled to the movement of the second touch input, wherein the second location is any location sufficiently distant from the first location to prevent the movement of a finger associated with the second touch input at the second location from affecting a view of the first location. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23)
