Method and Device for Processing Multi-Touch Input
First Claim
1. A multi-touch input processing method comprising:
- determining whether an overlapping region exists between a first input region and a second input region, when a multi-touch input occurs on a touch panel;
computing a center point of the first input region, a center point of the second input region, and a center point of the overlapping region when the overlapping region exists;
determining a first straight line passing through the center point of the first input region, a second straight line passing through the center point of the second input region, and a third straight line passing through the center point of the overlapping region;
computing the sum of touch input forces of a peripheral region of each of the first straight line, the second straight line, and the third straight line; and
comparing the sum of the touch input forces of the peripheral region of the first straight line or the second straight line with the sum of touch input forces of the peripheral region of the third straight line to determine whether to merge the first input region and the second input region.

Abstract
The present invention relates to a method and a device for processing a multi-touch input, comprising the steps of: detecting whether an overlapping region exists between a first input region and a second input region when a multi-touch input occurs on a touch panel; computing a center point of the first input region, a center point of the second input region, and a center point of the overlapping region when an overlapping region exists; determining a first straight line passing through the center point of the first input region, a second straight line passing through the center point of the second input region, and a third straight line passing through the center point of the overlapping region; computing the sum of touch input forces of regions surrounding each of the first straight line, the second straight line, and the third straight line; and determining whether to merge the first input region and the second input region by comparing the sum of the touch input forces of the regions surrounding the first or second straight line when the sum of the touch input forces of the regions surrounding the third straight line.
