Be described in further detail below in conjunction with embodiment and accompanying drawing thereof.

Embodiment

Referring to Fig. 2, disclosed a kind of basic circuit structure block diagram of realizing screen keyboard inputting method of the present invention among Fig. 2, comprising microprocessor 21 and the keystroke interface 22 that is connected with microprocessor 21 respectively, screen 23, RAM (random access memory) 24.Microprocessor 21 can be the chip that MCU (microprocessing unit) etc. possesses processing capacity, keystroke interface 22 can be the input interface of multidirectional key (five to key, nine to key or the like), screen 23 can be LCD or the like, and RAM24 also can be built in the microprocessor 21.

Input signal (comprising cursor movable signal and button confirmation signal) is delivered in the microprocessor 21 by keystroke interface 22, and microprocessor 21 can be judged and handles, and input signal is made a response by the information among the RAM24.Microprocessor can be handled graphic interface information simultaneously, input signal is sent to screen 23, by screen 23, the user can see operating process intuitively: moving cursor each time, screen 23 all can demonstrate the English alphabet that correspondence will be imported, numeral or out of Memory, this demonstration can be to give prominence to sign with comparatively significant color etc., also can use square frame, underscores etc. are made unique the sign, in a word, when cursor moved on certain button, screen message can be made very clear and definite prompting to the user, so that the user need to confirm the button of input, in case the user confirms certain button and has made corresponding action and (pressed acknowledgement key, be arranged on the centre of multidirectional key when acknowledgement key is general, certainly, also an acknowledgement key can be set separately), then microprocessor device 21 will receive the button confirmation signal, and at this moment, pairing letter of the button that is identified or symbolic information can show on screen 23, this mode is unusual technique known, does not do at this and gives unnecessary details.

Fig. 3 is wherein a kind of button arrangement mode of realizing screen keyboard inputting method of the present invention, its cooperate one nine to strong the use (on, down, a left side, right, upper right, upper left, the bottom right, eight directions in lower-left and acknowledgement key, acknowledgement key can be arranged on directionkeys central authorities), in this kind arrangement mode, comprise initial point in 25 interior button symmetry arrangement, wherein initial point is positioned at symcenter, 25 buttons among Fig. 3 can be represented 26 English alphabets, wherein initial point is re-used, be corresponding two English alphabets comparatively commonly used of initial point (for example letter " A " and " N "), the number of times that is pressed by acknowledgement key when input switches, for example, when the pairing letter of needs input initial point, press odd number time acknowledgement key, then input alphabet A presses even number time acknowledgement key, input alphabet " N " then, the respectively corresponding unduplicated English alphabet of other each button.

Can certainly adopt the button arrangement mode among Fig. 4, adopt 26 buttons, this arrangement mode is not complete symmetry, but initial point still is arranged on place, close on-screen keyboard middle position, that is, initial point is in the middle position of on-screen keyboard haply.Like this, just need not initial point is multiplexing, but the respectively corresponding letter of each button.Equally, the arrangement mode among Fig. 4 also cooperates one nine to strong use.

Disclosed the concrete steps that adopt 26 English alphabets of screen keyboard inputting method input of the present invention among Fig. 5, described details of the present invention in detail below with reference to Fig. 3, Fig. 4, Fig. 5.
