1. A touch gesture recognition apparatus comprising:
- a gesture recognizing unit configuredto detect a touch thereon, to create a bounding box surrounding a location where the touch occurs,to determine a calculated distance to be a length of the diagonal line of the bounding box,to recognize a gesture as a single-touch gesture or a multi-touch gesture by comparing the determined length of the diagonal line of the bounding box with a range of a threshold diagonal-line length, andto distinguish between the single-touch gesture and the multi-touch gesture touched consecutively using touch signals collected for a predetermined time period; and
an input event processing unit configured to map the recognized gesture to a user input event.

Abstract
Disclosed are a touch gesture recognition apparatus and method that can be, or applied to, both a single-touch system and a multi-touch system. The touch gesture recognition method recognizes touch gestures using the diagonal-line length of a bounding box created based on touch location information and variations in the diagonal-line length. After a gesture is recognized, the recognized gesture is mapped to an input event of a user input device and feedback according to the input event is provided.
