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.
