The visual enhancement module 7 will compare the remaining code symbols of the tiger 412 (four) image according to the comparison result of the bit code comparison unit 6丨, so that the image is available for use as The coded symbol image of the lower-bit code is highlighted by relative enhancement. ~ When the input of the single word 31 is performed, the operation mode of the whole system is substantially the same as that of the first embodiment 'only the code symbol 3^ displayed by the input window 51 is an English letter, and the single word 31 displayed in the quick selection window 51 is English. When the word is input to the input window 51, the code symbol 321 rc" is input, and the bit code is similar to the 13 201133279 unit 61. The code symbol 3 21 ' displayed according to the input window display 51 can be used for comparison from the font module 3 The sequence is used as the code symbol 321 of the next bit code, and the visual enhancement module 7 changes the code symbol 412 on the symbol buttons 411 of the button distribution area 413 according to the comparison result of the bit code comparison unit 61. The relative visual enhancement processing of the image, since the virtual image keyboard 41 has been first divided into two regions according to the shape feature of the code symbol 412, the visually enhanced code symbols 412 are more obvious and easier to recognize, so It is convenient for the user to quickly select the desired coding symbol 412. However, it must be noted that the symbols of the coded symbols 412 are faded, and the button button still has the function of being touchable, and the special code combination of the poems can be input, but when implemented, the speech code "4! 2 is The faded symbol button 4 is not necessary for being touchable. At the same time, the single-word matching unit 62 also compares the possible single words 3 from the font module 3 according to the input window 51=, and the combination of the encoded symbols 321 and records according to the recording module 8. The frequency and number of times of each word 31 are displayed in the quick selection window 排列 for the user to click. In the implementation, the virtual image keyboard 41 can be further divided into four or two button distribution areas 413. The shape symbols of the code symbols 412 on the symbol buttons of the button distribution area 413 are: having an arc but not having ^ Closed space outer shape feature, with closed space outer shape feature, only 1 line and vertical line (4) (four), and with external oblique line shape feature through this distinction, can also effectively improve the symbol button 4ΐι14 14 201133279 The recognition speed of the code symbol 412 and the single word input efficiency. Referring to FIG. 8 , in addition, the visual enhancement module 7 can also adopt the design of the first embodiment to directly eliminate the images of the remaining coding symbols 412. However, when implemented, the encoded symbols are compared. The way 412 images are relatively enhanced and highlighted is not limited to this.

In summary, the visual enhancement module 7 can be designed according to the code 321 of the bit code comparison unit 胄, and the visual enhancement processing such as the image symbol 412 corresponding to the virtual image keyboard 41 is faded or eliminated. The recognition speed of the code symbol 412 of the symbol button 411 can be effectively improved, thereby improving the input efficiency of the word 31, and the relative enlargement processing of the symbol (4) 4U and the code symbol 412 can be further transmitted, so that the text input system of the present invention is applied.
