Abstract
An apparatus and method for precise multi-touch input are provided. The method includes detecting a first touch input at a first location on a touchscreen; while the first touch input is maintained, detecting a second touch input at a second location 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 movement of the adjusted location is less than the movement of the second touch input.
Claims29
A method for precise multi-touch input, the method comprising:
- detecting a first touch input at a first location on a touchscreen;
- while the first touch input is maintained, detecting a second touch input at a second location 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 movement of the adjusted location is less than the movement of the second touch input.
An apparatus configured to provide a precise multi-touch input, the apparatus comprising:
- a display unit;
- a touchscreen operatively coupled to the display unit and configured to detect a touch;
- and
- a processor configured:
- to detect a first touch input at a first location on the touchscreen, to detect a second touch input at a second location on the touchscreen while the first touch input is maintained,
- to detect removal of the first touch input at the first location while the second touch input is maintained, and
- to adjust the first location according to movement of the second touch input, such that movement of the adjusted location is less than the movement of the second touch input.
A method for precise multi-touch input in an electronic device, the method comprising:
- detecting a user input;
- determining a first location on a touchscreen of the electronic device based on the user input;
- detecting a touch input at a second location;
- and
- adjusting the first location according to movement of the second touch input,
- wherein the movement of the adjusted location is less than the movement of the second touch input.
