Description

200939080 IX. Description of the Invention: [Technical Field] The present invention relates to an encoding method and encoding system, particularly to a multi-finger gesture encoding method and encoding system. [Prior Art] Existing touch modules, such as a touch panel (T〇uch panel) and a touch pad (Touch Pad), are often used in various information devices such as a Personal Digital Assistant (PDA). And Apple's © digital music player "iPod" and so on. In the initial development of the touch module, only a single track (also known as a single-finger gesture) drawn by a gesture (Gesture) can be sensed. However, the existing touch module has been improved to allow the user to gesture with one finger. (Multi-Finger Gesture) mode operation, such touch modules such as capacitive, inductive and other technology touch panels. The so-called multi-finger gesture is that the touch module can simultaneously sense the trajectory of more than one sensor (finger, stylus, or a mixture of the two). The touch module 11 analyzes the above gestures in the following manners: © Referring to FIG. 1, the information device (such as a computer, a mobile phone, a personal digital assistant, a digital walkman, etc.) includes the touch module 11 and an arithmetic unit (such as the central unit). Processing Unit (CPU), Microcomputer Unit (MCU), Digital Signal Processor (DSP), Application-Specific Integrated Circuit (ASIC), etc. 12 ° When the user touches the touch module 11 with a single-finger or multi-finger gesture, the touch module 11 generates a gesture signal and calculates a track signal, and the track signal is transmitted to the operation unit 12 of the 200939080 information device, and the operation unit 12 performs the operation. A combination of its trajectories is calculated to take a gesture and generate a corresponding action. In particular, the hand signal may be a voltage value change or other signal depending on the technology of the different touch module 11. The above-mentioned operation method, as shown in US Patent Publication No. US6002946 "HANDHELD DEVICE HANING AN OPTICAL DATA READER" and US Patent Publication No. US6639584 "METHODS AND APPARATUS FOR CONTROLLING A PORTABLE ❿ ELECTRONIC DEVICE USING A TOUCHPAD", belongs to the utilization information device itself. The arithmetic unit 12 calculates an trajectory signal and obtains an operation command. However, the disadvantage of the first mode of operation is that the computing unit 12 calculates the track signal by itself to obtain a gesture, which results in a lot of system resources, especially a portable mobile device that is slow in computing power efficiency. System resource consumption is more obvious. Referring to FIG. 2', in order to improve the performance of the self-calculating gesture by the computing unit 12, which results in a decrease in performance (especially when recognizing a multi-finger gesture), the existing touch mode group 11 has been improved to: when the user gestures with a multi-finger When the touch module 11 is touched, the touch module 1 generates a pair of multi-finger gesture codes that should be multi-finger gestures. The computing unit 12 executes a preset multi-finger gesture data table 121' to query the multi-finger gesture data table ι21 according to the multi-finger gesture code to execute a corresponding operation instruction. For example, the computing unit 12 is performing a playback picture software, and the user uses two fingers to make an action on the touch module U to make the two fingers move away from each other, and the touch module 11 transmits the 200939080 one. The designated multi-finger gesture mega-math, the computing unit 12 queries the multi-finger gesture data table 121 and confirms that the multi-finger gesture code is an action of zooming in on the screen, and then plays the picture in the picture software to enlarge the playing. Such as the US patent disclosure

No. US20070177804 "MULTI-TOUCH GESTURE DICTIONARY is a gesture dictionary that can apply our multi-finger gestures (like the multi-finger gesture data table 121 described above) to generate multiple touch functions. However, the output of the touch module 11 Single multi-finger gesture code is limited
