1. A multi-touch decision apparatus comprising:
- a sensor to sense an object contacting a specific position corresponding to one among a plurality of sensing channels arranged in a predetermined array;
a detector to detect at least one of information about signal strength of the sensing channel in which the object is sensed and information about the number of sensing channels having a signal strength exceeding a first threshold; and
a controller to determine whether a single touch or a multi touch has been sensed based on the detected information,wherein when the number of sensing channels having the signal strength exceeding the first threshold is greater than a second threshold, the controller determines that a multi touch has been sensed.

Abstract
A multi-touch decision apparatus, method, and medium are provided. The apparatus includes a sensor to sense an object contacting a specific position corresponding to one among a plurality of sensing channels arranged in a predetermined array, a detector to detect at least one of information about signal strength of the sensing channel in which the object is sensed and information about the number of sensing channels having a signal strength exceeding a first threshold, and a controller to determine whether a single touch or a multi touch has been sensed based on the detected information.

7. A multi-touch decision apparatus comprising:
-
a sensor to sense an object contacting a specific position corresponding to one among a plurality of sensing channels arranged in a predetermined array; a detector to detect at least one of information about signal strength of the sensing channel in which the object is sensed and information about the number of sensing channels having a signal strength exceeding a first threshold; and a controller to determine whether a single touch or a multi touch has been sensed based on the detected information, wherein when the sum of the signal strengths and the number of sensing channels having a signal strength exceeding the first threshold respectively exceed predetermined values, the controller decides that a multi touch has been sensed. - View Dependent Claims (8)

9. A multi-touch decision method comprising:
-
sensing an object contacting a specific position corresponding to one among a plurality of sensing channels arranged in a predetermined array; detecting at least one of information about signal strength of the sensing channel in which the object is sensed and information about the number of sensing channels having a signal strength exceeding a first threshold; and deciding whether a single touch or a multi touch has been sensed based on the detected information, wherein when the number of sensing channels having the signal strength exceeding the first threshold is greater than a second threshold, there is a determination that a multi touch has been sensed. - View Dependent Claims (10, 11, 12, 13, 14, 15)
