Embodiment
Referring to Fig. 1-Fig. 5, a kind of single-hand operated keyboard mainly is made up of the key on coded scanning circuit, signal transmission interface, chassis and the chassis, and this keyboard has 34 keys, is divided into 5 row, 7 row.Its key is divided into alphabetic character key, switch key, special function keys, each main key is divided into I, II, four districts of III, IV, i.e. key position, described switch key removes the SHIFT key is set, and other increases left crosspiece key L﹠amp; RSHIFT and lower gear key DWNSHIFT.Special function keys is provided with enter key, space bar, CTRL key, ATL key and FUN key.
A kind of various full word symbol input methods that need character of above-mentioned single-hand operated keyboard input that adopt are stored into its input method software in the chip of keyboard coding sweep circuit, also can be with the input method software solidification on the chip of keyboard coding sweep circuit.With the key definition of keyboard be: alphabetic character key (as key) based on 26 English alphabets; Special function keys (as enter key, space bar, CTRL, ATL, FUN); Switch key (as shift SHIFT capital and small letter switch, lower gear key DWNSHIFT-switches up and down, left crosspiece key L﹠amp; Switch about RSHIFT-); Each main key is divided into I, II, four districts of III, IV, i.e. key position, the I district mainly is 26 English alphabets, five special function keys, three switch keys for the acquiescence district; The II district is following keypad, needs cooperate input with the lower gear key, mainly be punctuate, special symbol and part usual function keys, as DWNSHIFT+D="? ", other are analogized; The III district is a left key area, needs to cooperate input with left crosspiece key, and mainly be numeral, sign of operation and part usual function keys, as L﹠amp; RSHIFT+D=" 3 ", other are analogized; The IV district is the lower-left keypad, needs to cooperate input simultaneously with lower gear key and left crosspiece key, and mainly be of little use symbol and function key, as L﹠amp; RSHIFT+DWNSHIFT+D="＜".
The concrete operation method of the embodiment of the invention is:
When input device prompting, input character according to the following steps:
(1) English (I district) (see figure 2) of input
(1.1) when device prompting input, directly button is then imported with key and is marked identical small letter English alphabet; Cooperate with shift, finish the single input of English alphabet capitalization;
(1.2) when CapsLock opens, the operation of (1.1) changes the full capitalization input of English alphabet into; Cooperate the single input that changes the English alphabet small letter into shift, close CapsLock again, change back
(1.1) operation;
(1.3) under the state that NumLock opens, cooperate input small letter English alphabet with left crosspiece key; Cooperate with left crosspiece key and shift, import single capitalization English letter;
(1.4) when CapsLock and NumLock open simultaneously, cooperate, import full capitalization English letter with left crosspiece key; Cooperate with left crosspiece key and shift, finish the single input of English alphabet small letter;
(2) input punctuate and special symbol (II district) (see figure 3)
Correspondent button cooperates with the lower gear key, imports corresponding punctuate and special symbol (comprising usual function keys);
(3) input digit and sign of operation (III district) (see figure 4)
(3.1) correspondent button cooperates with left crosspiece key, input corresponding digital and sign of operation (comprising usual function keys);
(3.2) NumLock is opened, then the III district changes the acquiescence district into, directly imports the numeral and the sign of operation (comprising usual function keys) of correspondent button position, II, IV district input mode constant (this moment, input was English, referring to 1.3 and 1.4); Again by closing or cut off the power supply, the cancellation default conditions.
(4) import be of little use symbol and function key (IV district) (see figure 5)
Correspondent button cooperates simultaneously with lower gear key and left crosspiece key, imports be of little use accordingly character and function key.
(5) when pressing the FUN key, only effective with the numerical key of corresponding 1-12, promptly import F1-F12; When NumLock opens, need to cooperate input F1-F12 with left crosspiece key.Other has 19 to reserve the key position, is available for users to freely define.
The difference of key and key position: this keyboard has 34 keys, and most buttons have 4 districts, i.e. key position.No specified otherwise, its key name is with the letter representation in I district.As DWNSHIFT+D, inferior segment (the being the II district) character of expression I key position, promptly "? ", other are analogized.
During operation, left index finger, middle finger, the third finger, little finger of toe, thumb are placed on respectively on F, D, S, A and the lower gear key, promptly initial bit behind the intact key of every operation, is pointed and is got back to initial bit.Little finger of toe is responsible for H, N, B, L﹠amp in principle; RSHIFT, A, Q, Z, each key of FUN; The third finger is responsible for J, C, S, V in principle; Middle finger is responsible for K, E, D in principle, takes into account SHIFT; Forefinger is responsible for L, M, P, R, T, W, F, G, I in principle, takes into account U, O, Y; Be responsible for SHIFT, DWNSHIFT, ENTER, SPACE, X, CTRL, ALT on the rules of thumb, take into account U, O, Y, even FUN, I.Meaning in principle is, after the key position is very skilled, respectively refers to and can break set form according to the practical operation needs, to cover the shortage mutually, realizes respectively referring to that equifrequent is used equably, makes every effort to operation the fastizationest with reaching input.Special many combinatorial inputs are prerequisite with convenient, fast.
This embodiment illustrates suitable left-handed operation, be suitable for the key form Pareto diagram of right-hand operated can symmetrical image promptly.
The keyboard scan principle:
This keyboard adopts the minor matrix keyboard of 34 keys, and in order to realize the input function of standard 101-key keyboard, most buttons have designed 4 heavy input functions.Set up DWNSHIFT, L﹠amp on the keyboard; Two keys of RSHIFT are distinguished different input functions by it, for example:
During program design,, set up 4 page key code table lattice Pareto diagrams, the key value under the corresponding different input states of every key form at first according to the arrangement of key position.
In the key scan subroutine,, at first go shake, then according to DWNSHIFTT, L﹠amp if there is button to press; The state of RSHIF key is provided with the corresponding first address of tabling look-up, and is calculated by the key place value of button and generates the pointer of tabling look-up, and finds corresponding key (seeing Table 1).This key is kept at the transmission buffer zone, is started by the timing subroutine to send.
Table 1
| DWNSHIFT | ? | Form | |
| 0 | ?0 | I district | |
| 0 | ?1 | III district | |
| 1 | ?0 | II district | |
| 1 | ?1 | IV district key form |
When concrete enforcement single-hand operated keyboard of the present invention and input method software thereof, its circuit and program can be with reference to Fig. 6-Figure 13.
Single-hand operated keyboard of the present invention and input method thereof can be widely used in desk-top computer, notebook, palm PC, mobile phone and various instrument, equipment.
