7. The method of claim 6, comprising sensing the plurality of actuations of the keys which correspond to the break-down in which: (i) characters are characterized as having four basic patterns: left-right, up-down, embracing, and singular, the four basic patterns, corresponding to relative locations of roots within each character the four basic patterns being allotted numerical codes 1, 2, 3, and 4, according to frequencies of the four basic patterns in practical Chinese usage; and (ii) twenty-five blocks of the roots are arranged on twenty-five keys of the keyboard arranged both in a traditional Western alphabetic placement and in accordance with a frequency of each of the twenty-five blocks in practical Chinese usage, each of the twenty-five blocks having a two-digit numerical code representing its location wherein: a. one digit of each two-digit numerical code represents the numerical code allotted to one of the five sections and another digit of each two-digit numerical code represents the numerical code allotted to one of the five blocks within the one of the five sections; b. for twenty of the twenty-five keys each numerical code also represents a combination of one of the five basic types with one of the four patterns, with one digit of each two-digit numerical code being the numerical code alloted to the one of the five basic types and the other digit of each two-digit numerical code being the numerical code allotted to the one of the four basic patterns; and c. a most frequently used root in each block is chosen to represent the name of the key in which the block is located.

The method of claim 7, comprising, for a character which is in itself a root and appears on a key but is not used as the name of the key, sensing actuations of the key and of those keys which correspond to the first stroke of the character, the second stroke of the character and the last stroke of the character.
