Definitions

• the invention relates to a letter key coding of a combined keyboard.
• the invention is mainly applicable to a keyboard with a limited volume and a limited number of keys, and in particular, a mobile phone, a telephone, a PDA, a notebook computer, a computer and its terminal, a vending machine, information appliances (such as a network television, a network refrigerator), and electronics.
• a small keyboard device for things like combination locks. Background technique
• the known keyboard codes are sequentially coded according to the arrangement order of the letters on the alphabet.
• it is used in an adjacent key combination keyboard, there may be multiple different input methods for adjacent key positions, so it is easy to make a mistake.
• the standard tandem 12-key (4 rows and 3 columns) numeric keypads use adjacent key combination keyboards. Each row has 3 directly selected key positions and 2 "horizontal” key combinations. There are also 3 "vertical” key combinations. In this way, although each key position can be directly selected, there is no obvious rule in this arrangement. For example, if a commonly used alphabetic sequence code is used (as shown in Figure 3), then the adjacent letters of the alphabet will have 3 on the keyboard. Different key selection methods (as shown in Figure 3, (the four consecutive letters of D, E, F have 3 different key selection methods), it is difficult to adapt.
• the present invention provides an alphabetic key position coding of a combination keyboard that is easy to memorize, and uses the following technical solutions:
• An alphabetic key code of a combination keyboard where: at least a specific set of phases exists between key codes A, B, C, D, E, F, G, H, I, J, K, L, M, N Neighbor relationship and combination relationship. Confirm this In the above coding, two adjacent keys pressed simultaneously can generate a combination key bit.
• Key codes A, B, C, D, E, F, G, H, I, J, K, L, M, N exist at least a specific set of adjacent relationships, where at least a set of A, B, The C, D, H, I, J, K key positions are single key positions, and the E, F, G, L, M, N key positions are combination key positions.
• the adjacent relationship between the single-key position key codes is A, 6, and H are adjacent; B is also adjacent to C, I; C is also adjacent to D, J; D is also adjacent to K Adjacent; H is also adjacent to I; I is also adjacent to J; and J is also adjacent to K; the adjacent relationship between the single bond key code and the combined key bit code is 5 and people, B Adjacent;? It is adjacent to ⁇ C; 0 is adjacent to ⁇ and D; L is adjacent to H and I; M is adjacent to I and J; and 1 ⁇ is adjacent to ⁇ 1 and K.
• Key codes A, B, C, D, E, F, G, H, I,. J, K, L, M at least have a specific combination of relationships, where the key code of the combination key is pressed simultaneously Generated by two adjacent single-key key codes in the same row.
• the combination of A and B keys generates the E key
• the combination of B and C keys generates the F key
• the combination of C and D keys generates the G key
• the combination of H and I keys generates the L key
• the combination of I and J keys generates the M key.
• the J and K key combinations produce N bonds.
• the present invention relates to the coding of alphabetic key positions, so numbers and symbol key positions are not marked on the drawings, and the setting of the alphabet and symbol keys will not affect the scope of use of the present invention.
• FIG. 1 shows a fixed adjacent feature table between a specific single key and other single keys, and a specific single key and a combination key

• FIG. 19 is a schematic diagram of the vertical key combination of the keyboard shown in FIG. 16;
• the present invention is a keyboard code formed according to two habits of people learning and using the alphabet.
• the basic encoding method of the present invention is that on a 4-row 4-column combination keyboard, alphabets 1-4 columns of alphabets are set as radio buttons in the same arrangement order, and 5-7 columns of alphabets are set as combination keys in the same arrangement order, and 5, 6, Each letter in the 7 columns is generated by a combination of two radio buttons in the same row and adjacent columns ( Figure 4).
• the arrangement of keyboard keys is very similar to that of the alphabet, so it is easy for anyone familiar with the alphabet to remember.
• each letter (or character) on the "horizontal" combination area is composed of 2 adjacent "horizontal" lines on the coded alphabet that are on the same line as the letter.
• Direct selection letter keys to generate combined codes for example, as shown in Figure 18, the three "horizontal" combination keys E, F, and G in the first row of the coding table are respectively selected by the direct selection keys A + B, B + C, and C + D in the same row (Combination generated); "vertical" combination area is the combination key generated by the two vertical selection letter keys in the same column "vertical” in the same column on the coding table (for example, Figure 19, the 4th row of the coding table, 6 combination keys 1 ?, S, T, U, V, and W are the direct selection keys A + H, B + I, C + J, H + X, I + Y, J + Z in the same column respectively)).
• a horizontal 4-row 4-column keyboard can be regarded as a special case of a 4-row 3-column keyboard, with only a direct selection area and a "horizontal" combination area. For keyboards with less than 28 characters, the "vertical" combination area and key combination are generally not required.
• the present invention is not only suitable for the above-mentioned combination keyboard, but also can be made into a key value table for a virtual combination keyboard with fewer key positions (Fig. 14).
• a key value table for a virtual combination keyboard with fewer key positions (Fig. 14).
• at least 4 input keys are needed: Fl, F2, F3, F4, and their output values depend on the specific status of the key table.
• Fl, F2, F3, and F4 alone to output characters A, B, C, D, respectively; simultaneously press Fl + F2, F2 + F3, F3 + F4, respectively, to output characters E , F, G.
• you want to select other characters you can scroll through the key value list by pressing the up and down scroll keys.
• the present invention does not indicate the positions of numbers and symbols on the drawings. Because the setting of letters and symbol keys does not affect the scope of use of the present invention, the key code of the present invention is used only for the positions of numbers and symbols. Specific changes should not be considered as exceeding the scope of the invention disclosed in the present invention.
