Method for providing user interface using multi-point touch and apparatus for same
First Claim
1. A method of providing a user interface using a multi-point touch, the method being performed by an apparatus that includes a touch region capable of sensing contact and the method comprising:
- sensing contact at two or more different points in the touch region;
when the contact with the two or more points is sensed;
sensing whether the contact with the two or more different points is maintained and fixed at corresponding two or more positions in the touch region, anddetecting directions of force applied to the two or more different points; and
executing a predetermined user command according to a combination of the directions of force detected at the two or more different points when the contact with the two or more different points is maintained and fixed at the corresponding two or more positions in the touch region.

Abstract
The present invention relates to a method for providing a user interface using a multi-point touch capable of immediately carrying out various user commands by changing the direction of force applied to two or more different points inside a touch area, and to an apparatus for same, wherein when contact on two or more different points inside the touch area is sensed, directions of force applied to the two or more points are detected while the contact to the two or more points is maintained when the contact on the two or more points is detected, and a predetermined user command is carried out according to a combination of the directions of force detected from the points.

9. An apparatus for providing a user interface using a multi-point touch, the apparatus comprising:
-
a touch input unit including a touch region capable of sensing contact and configured to sense one or more of contact with the touch region, a position of the contact, an intensity of force upon the contact, and a direction of the force; and a control unit configured to, in response to the contact with the two or more points in the touch region being maintained and fixed at corresponding two or more positions in the touch region; check directions of force applied to the two or more points, and execute a predetermined user command according to a combination of the checked directions of force. - View Dependent Claims (10, 11, 12, 13)

14. A method of providing a user interface using a multi-point touch, the method being performed by an apparatus that includes a touch region capable of sensing contact and the method comprising:
-
sensing fixed contact at each point of two or more different points in the touch region; detecting a direction of force applied to each point of the two or more points of the fixed contact; and executing a predetermined user command according to a combination of the direction of force applied at each point of the two or more points when the fixed contact is stationary, wherein the combination is parallel to a line or a plane as defined by the two or more points or inclined the line or the plane at an angle with respect to the line or the plane.
