1. A gesture processing method for use with a touch screen, the gesture processing method comprising steps of:
- receiving a position signal;
transmitting the position signal to a first gesture engine and a second gesture engine;
generating a top-layer image, wherein a content of a workspace is covered by the top-layer image;
determining whether a first type gesture event is generated, wherein if the first type gesture event has not been generated, the top-layer image is adjusted according to a plurality of second type gesture events which are successively generated before the first type gesture event, wherein when the first type gesture event is generated, the top-layer image is adjusted according to the first type gesture event;
generating a gesture end event and accordingly adjusting the content of the workspace when the first type gesture event is no longer generated; and
removing the top-layer image after the workspace is adjusted.

Abstract
A computer system with a touch screen and a gesture processing method are provided. The computer system has a gesture hook unit for receiving a first type gesture event from a first gesture engine and a plurality of second type gesture events from a second gesture engine. A top-layer image is adjusted according to the first type gesture event and the second type gesture. In such way, an image shown on a workspace of an application program is smoothly changed in response to a gesture of a user.

6. A computer system with a touch screen, the computers system comprising:
-
a touch screen for generating a position signal in response to a touch point; a first gesture engine for generating a first type gesture event in response to the position signal; a second gesture engine for successively generating a plurality of second type gesture events in response to the position signal before the first type gesture event is generated; an application program having a workspace; and a gesture hook unit for capturing a content of the workspace, thereby generating a top-layer image to cover a content of the workspace, wherein the gesture hook unit further judges whether the first type gesture event is generated, wherein if the first type gesture event has not been generated, the top-layer image is adjusted according to the second type gesture events, wherein when the first type gesture event is generated, the top-layer image is adjusted according to the first type gesture event, wherein when the first type gesture event is no longer generated, a gesture end event is generated and the workspace is accordingly adjusted before the top-layer image is removed. - View Dependent Claims (7, 8, 9)
