Description of the Invention: [Technical Field] The present invention relates to an acceleration sensing type handwriting input device and an input method thereof, particularly in a handheld wireless communication device (such as a mobile phone - M〇bile Phone, personal digital assistant) -Pers〇nal Digital Assistance, ρΜ) The method of handwriting input characters. [Prior Art] With the advancement of the information age, handheld electronic devices have become more and more popular. The handheld electronic device has become a must-have item for handheld electronic devices, and it is an indispensable item for hand-held electronic devices. Miniaturization, eve, the number η has long been relegated to the traditional keyboard (some even the number keys have been taken) and switched to the resistance or capacitive touch screen (touch panel) with a kind of ratio / value conversion right The group is made into an analog/digital conversion chip) to the device. Gun, θ Λ The touch screen used in the application directly attaches a transparent touch=board to the screen. The touch screen has a constant weight and a thin dryness and poor light transmission. Adding it to the effort to achieve light, thin, short, and small = holding the buns, "prepared to become a great burden. Also, due to the limitation of the touch screen setting=up j, when using the input character, it is necessary to hold the stylus, hold the rabbit in hand, or prepare the support to place the device. Losing characters is still not very convenient to use. SUMMARY OF THE INVENTION In order to solve the above (four) knowledge of the touch panel as the underlying technology of the handwriting input method 1299138, the inter-axis 2 Ming is using the currently published, can obtain - the index of the displacement vector compensation technology in ^4553 (For example, the handwritten rounding method D of Taiwan's announcement form, combined with the analog/digital conversion module, designed a new one. The handwriting input device that provides a special design contains: data ^change ^ handle set' contains An accelerometer and analog 7 digits are used by %:~ for "recorded by the handheld electronic device in the space of the private movement 4 cut and converted to secret digital data; - central processing, 1 The above-mentioned obsolete digital data is compared with the trace digital data of the storage module described later = row and the approximate degree of N is low, and the matching character data is stored for her, including - shouting the record digit dragon and character data / The "upper speed central processing module query. In order to achieve the function of inputting characters, another object of the present invention is to provide a specially designed handwriting input method for placing the displacement vector system module of the handheld electronic device towel to record hand & The electron is slightly in the wheel of the herringbone tree, the trajectory moved in the space, and is converted into the observing digital data, and the central processing module is used to digitize the trajectory and the pre-defined storage model. #Material comparison, in order to find qualified character data for the user to select, to achieve the function of character input. [Embodiment] The preferred embodiment of the present invention will be described in detail below with reference to the drawings. As shown, the present invention is mainly applied to an input message in a handheld electronic device. The handwriting input device includes a displacement vector side mode = 1299138 1 , a central processing module 20 and a storage module 30, wherein · Λ displacement inward detection module 10, which is provided with an acceleration sensor 1〇1 air ratio /, bit data converter is removed, the acceleration sensor is written in space by using ^ record two handheld electronic devices When the character and the track moved when the character is to be input are sampled, the sample data is converted into the trace digital data by the analog/digital data converter 102. The central processing module 20 Track digital data and later storage The trajectory digital data of the pull group is compared, and the matching character data alternative is listed by the high and low approximation degree. The storage module 30 includes a built-in association table of the trajectory digital data and the character data for the central part. The processing module 20 queries. Continued, as shown in FIG. 2, the main operational steps of the devices are as follows: First, the user inputs the electronic device to write the input character track in the space (step S100), and then the displacement is performed. The acceleration sensor 101 built in the vector system module 1 records the character trace and samples it, and continues to convert the sample data into a trace digital poor material by another built-in analog/digital data converter 102. (Step S200). The central processing module 2 compares the trajectory digital data with the pre-established trajectory digital data in the storage module 30 (step S300) to list the storage mode from high to low. The character data associated with the group is selected (step 4〇〇), and finally the correct character is selected by the user (step S500). As shown in FIG. 3, the present invention can also add a learning function. - After the step S5 of selecting the correct character by the user, the selected digit information and character of the positive 1299138 character can be selected. Within the material (step S501), adding #ΊΓ_λ bf^ 豕 to the storage module can add - the glyph data of the same type of data, the data bit =::1° _ ratio / digit ^ x ^ 』 The self-sufficient private direction 1 detection module ίο内蒋屮, #央处理模块 20, by the central processing module 2 digital data converter 102 function. Build the pain ratio / the acceleration on the electronic device of the above (4) = use the displacement vector to detect the additional touch panel on the input interface of the ostomy input _^^^ machine, for the help of the present invention] The weight reduction, thickness reduction, and brightness of the screen can be 2. The handwriting input on the _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ Writing = type to round the person's text symbol, has been in line with the special shot request. However, each of the above is only a preferred embodiment of the present invention and is not intended to limit the scope of the present invention. That is, the equal changes and the modifications made by the scope of the patent application of the present invention are covered by the scope of the invention. [Simple Description of the Drawings] ^ 1 is a system architecture diagram of the handwriting input device of the present invention. ^ 2 is a main operation flow chart of the handwriting input device of the present invention. Figure 3 is a main operational flow diagram of another embodiment of the handwriting input device of the present invention. 1299138 [Main component symbol description] ίο displacement vector detection module ιοί acceleration sensor 102 analog/digital data converter 20 central processing module 30 storage module step S1GG Puer equipment in space towel write ridge input step S2G0 conversion The above characters are traced to the track digital data.
