Embodiment
The present invention can be applicable to the various electronic products that are provided with touch-screen and need literal input, as portable palm PC, PDA etc., below only is example with using in mobile phone, describes the present invention in detail.
See also Fig. 1, the touch-screen of mobile phone generally comprises text box 10, dummy keyboard 20 and input field 30.Wherein, dummy keyboard 20 is used for input and word selection, and input field 30 is used to show intermediate informations such as list entries, candidate pinyin combination, and 10 of text boxes are used to show final input results.
Comprise several character keys 22 on the dummy keyboard 20, several function key 23 and one are used for the candidate bar 24 of display candidate characters, and (candidate bar 24 there is no visual boundary with other parts of dummy keyboard 20, therefore be represented by dotted lines its scope in the drawings), wherein, function key 23 and character keys 22 sizes are identical or be slightly smaller than character keys 22,24 of candidate bar are because the restriction of dummy keyboard 20 areas and between two line character keys 22, its row is farsighted less than character keys 22, and generally speaking, the number of the candidate item 26 of required demonstration is more than character keys 22 numbers of every row in the candidate bar 24, so the area of each candidate item 26 is much smaller than character keys 22 areas, so that difficultly choose with click.Input for the convenience of the users, all keys on the dummy keyboard 20 of the present invention will produce in by some the time as variable color, become greatly, brighten etc. that one or more are easy to by the variation of user's perception, click success to point out the user; 24 input conditions according to the user of candidate bar dynamically demonstrate no more than four candidate item 26, each candidate item 26 comprises direction signs and one group of character to be selected, need not accurately to click candidate item 26 during word selection, and as long as the Directional Sign indicated direction to arbitrary candidate item 26 is rule on dummy keyboard 20, can choose corresponding candidate item 26, after line finished, the character to be selected on this candidate item 26 was shown in text box 10.
Please continue to consult Fig. 2 and Fig. 3, will import " sending out " word with spelling input method is example explanation input process.Below be that to select input pen be that instrument carries out operations such as keystroke, line in the explanation, but during actual input,, can operate accordingly with finger equally as long as touch-screen allows.
Click " sending out " word phonetic " f " at first in turn, two character keys 22 at " a " place, when " def " of dummy keyboard in input pen point key region, " def " key produces and is easy to by user's change perceived (figure does not show), click this key success with the prompting user, lift input pen this moment, " def " promptly imports successfully, input field 30 shows " def ", four candidate item 26 appear in the candidate bar 24, show respectively corresponding " d ", " e ", the most frequently used Chinese character of " f " and separately Directional Sign, promptly four candidate item 26 are shown as " ↓ starve " respectively, " ↑ dislike ", " ← pretty young woman ", " → Russia " (direction signs in the present embodiment are arrow); Afterwards by clicking " abc " with quadrat method, input field 30 promptly demonstrates " def " and " abc " all possible pinyin combinations " da fa ", this moment, four candidate item 26 demonstrated the most frequently used Chinese character of corresponding above-mentioned pinyin combinations and Directional Sign separately respectively, and promptly four candidate item 26 are shown as " ↓ big ", " ↑ ", " ← method ", " → beat " respectively; At this moment, only need according to the arrow prompting, in the upwards line of any position of dummy keyboard 20, " ↑ send out " key promptly can change, the success of prompting user word selection, and " sending out " word is imported successfully when lifting pen, is shown in the text box 10.Simultaneously, system may be shown in candidate bar 24 as character to be selected with the Chinese character of " sending out " word logotype.
If when input field 30 showed a plurality of pinyin combinations, character to be selected was not shown in candidate bar 24, the user can click pinyin combinations accurately on input field 30, make 24 candidate item 26 that show accurate pinyin combinations correspondences of candidate bar; If after choosing accurate pinyin combinations, character to be selected is not shown in candidate item 26 yet, can search by the page turning key page turning, and in character to be selected was shown in a certain candidate item 26 of candidate bar 24, screen was gone up in line again.
In sum, the present invention is used for the input method of touch-screen to carry out word selection to the mode of specific direction line, has avoided because the too small accurately problem of click that is difficult to of candidate item 26 areas greatly facilitates the user.Certainly, " to the specific direction line " is not that the drawn line of requirement is necessary for straight line, and the direction that neither require to rule must be in full accord with the direction of direction signs indication.In fact, the disposal system of electronic equipment is to judge input results with the starting point O and the vector between the terminal point M (hereinafter referred to as " vectorial OM rules ") of line, therefore, no matter the actual line route (hereinafter referred to as " incoming line ") of input pen why, as long as its starting point O is identical with terminal point M, input results will be identical.And according to default, as long as the direction of the vectorial OM of line and the angle (hereinafter referred to as " deviation angle ") between a certain direction signs direction are not more than a certain limit value, this line operation promptly can be accepted as effective input by system.
Seeing also Fig. 4, represent the direction of arrow of four candidate item 26 in the above-mentioned embodiment respectively with the positive negative direction of two coordinate axis, serves as the line starting point with true origin O, and the institute's shaded portion among the figure then is effective input range of the vectorial OM of line.As seen from the figure, dash area is a zhou duicheng tuxing, abscissa axis x axle and axis of ordinates y axle all are its axis of symmetry, ∠ A is the boundary line of dash area and the angle between the most contiguous coordinate axis, size is 30 degree, that is to say, as long as the vectorial OM of line is not more than 30 degree with respect to the deviation angle of direction signs, can be by being accepted as effective input by system after the touch-screen perception, the character of this direction signs place candidate item 26 can be imported smoothly.Therefore, according to the direction of the vectorial OM of line among Fig. 4 as can be known, incoming line a will be used as by system and import last line and handle, and promptly after dummy keyboard 20 marks incoming line a, the character that shows on the candidate item 26 of " ↑ " will be shown in text box 10.In like manner, incoming line b, c and incoming line a have same starting point O and terminal point M, the line vector OM that shows three incoming line a, b, c is identical, and system can be used as incoming line b, c equally and imported last line and handle, and the character on the candidate item 26 that shows " ↑ " is shown in text box 10.Like this, the user is when word selection, if because carelessness or other reasons are drawn wrong direction, so that change be not the character of own desire choosing the time, can need not to lift pen, correct direction as long as continue line, after required character changes, lift pen again, can import correct character.Certainly, in other embodiments, the limit value of the deviation angle of the vectorial OM that rules is adjustable, and in the induction zone that four line directions are arranged, the limit value of deviation angle can be any angle less than 45 degree.
In addition, because during user's click keys, the drop point of unlikely assurance input pen on dummy keyboard 20 really is one " point ", click keys operation for fear of displacement is slightly handled as line, set in the system when the length of the vectorial OM of line is not more than 5 pixels, to be handled as " point ", promptly when this " point " when dropping on the button, system operates it as click keys, when " point " drops on scope beyond the button on the dummy keyboard 20, be taken as invalid input and handle.
See also Fig. 5, be second embodiment of the present invention, the dummy keyboard 20a in this embodiment comprises word selection induction zone 32 and page turning induction zone 34 two parts, and character keys 22a and candidate bar 24a are in word selection induction zone 32, and function key 23a is in page turning induction zone 34.In the input process, after the candidate bar 24a on the dummy keyboard 20a demonstrated candidate item 26a, the user need could be shielded on the successful word selection to the specific direction line in word selection induction zone 32; If character to be selected is not shown in when consequently needing page turning to search in four candidate bar 24a, the page turning of can in page turning induction zone 34, ruling, wherein go up line and represent page turning forward, underscore is represented page turning backward, the direction signs prompting that this zone can light up or down in the scratching process is rule successfully, lifts a back page turning success.Wherein, system is to identical among the judgement of incoming lines in the word selection induction zone 32 and the processing mode and first embodiment, promptly the deviation angle of direction sign is determined input results by the vectorial OM that rules, it is 30 degree that the maximum of vectorial OM of ruling allows deviation angle, and deviation angle is invalid input greater than the line vector OM of 30 degree.System is to be foundation with the vectorial OM that rules to the judgement of incoming lines in the page turning induction zone 34 equally, different is, because this zone only needs two line directions up and down, the deviation angle of vectorial OM is effective input so long as not 90 degree so rule, that is to say, be only invalid input when having only the line vector for horizontal vector.What deserves to be explained is, if the terminal point M of a vectorial OM of line drops in the starting point O place induction zone zone in addition, system still can determine the line input direction with the rule deviation angle of vectorial OM of reality, just can be with the zone at starting point O place as the line effective coverage, draw to the right to the incoming line of page turning induction zone 34 by word selection induction zone 32 levels such as one, its input direction is judged to be right line, the line effective coverage is judged to be word selection induction zone 32 according to the position of starting point O, be that this line operation will be chosen the candidate item 26a that has shown right line, the character of lifting on the right line in the pen back candidate item 26a to be selected is shown in text box 10a.In other embodiments, line about the page turning of page turning induction zone 34 line direction also can be defined as is represented page turning forward such as left side line, and page turning is backward represented in right line, and the permission deviation angle of line vector is similarly less than 90 degree.
In other embodiments, the word selection success also can be pointed out by other modes, such as the somewhere of touch-screen (can be fixed position or not fixed position) is made as the word selection prompting frame, character in this frame changes along with moving of input pen, after the user lifts pen, the last character that shows of word selection prompting frame will be transfused to text box 10.
The present invention be equally applicable to stroke input method, English input method or other input methods input, select character/word.When importing with stroke input method, above-mentioned input field 30 will be used to show the stroke of having imported, the word that candidate item 26,26a then show and the stroke of importing is complementary, speech etc. show the arrow as the line Directional Sign simultaneously as character to be selected, and the user rules by direction can the word selection input.The Word selection method of the word selection of other input methods and phonetic and stroke input method is not roughly the same done herein and is given unnecessary details.
The announcement of book and instruction according to the above description, those skilled in the art in the invention can also change and revise above-mentioned embodiment.Therefore, the embodiment that discloses and describe above the present invention is not limited to also should fall in the protection domain of claim of the present invention modifications and changes more of the present invention.In addition, although used some specific terms in this instructions, these terms do not constitute any restriction to the present invention just for convenience of description.
