Embodiment approach 1
[0016] Embodiment 1 In the two-dimensional table of this embodiment, a character that only appears in one character column is called a single character, and the same character column can only have one single character. Therefore, a single character in the two-dimensional table can be The basic input key input corresponding to the column where the character is located; the character that appears at least twice in different columns is called a multiple character, and each character in it is called the sub-character of the multiple character, and the number of sub-characters of different multiple characters can be different, one The combination of the column where the sub-characters of multiple characters are located is called the sub-character combination of the multiple characters. Any two sub-character combinations of multiple characters are different. Therefore, the multiple characters in the two-dimensional table can be formed by clicking the sub-character combination Corresp...

[0017] Embodiment 1 Digital touch typing input anti-peep password keyboard
[0018] Fig. 2 is the schematic diagram of the keyboard body of the present embodiment;
[0019] FIG. 3 is a schematic diagram of the privacy cover of this embodiment.
[0020] On the keyboard body shown in Figure 2, the five strip-shaped basic input keys are separated from each other by the partition plate 4 shown in the figure, so that the five fingers can be positioned accurately on the corresponding basic input keys; The five fingers are naturally positioned and arranged in a staggered front and back, and the keyboard body and the privacy cover are also designed in the shape of a palm according to the length arrangement of the five fingers, so that the inputter can search for characters on the privacy cover more intuitively and quickly.
[0021] The upper surface of the anti-peep cover shown in Figure 3 is marked with a virtual key surface consisting of ten numbers from 0-9 and characters of "conf...
Embodiment approach 2
[0026] Embodiment 2 In this embodiment, the corresponding column of each row of the virtual key surface two-dimensional table is marked with more than one identification symbol 6. The above-mentioned identification symbol refers to the symbol or color located in the corresponding column in a character row. Different rows The number of the above-mentioned identification symbols can be different; the combination of all the identification symbols of a character row in the column is called the identification symbol combination of the row, and the combination of identification symbols of any two different character rows are not the same; there can be one in the same character column The above different single characters; according to the method of two-dimensional plane coordinate positioning, for any character in the two-dimensional table of the virtual key surface, as long as the column and row where it is located can be located, the character can be positioned, so, by first clickin...
