Along with popularizing of touch-screen, the application of input gesture that is used to carry out various instructions is very common.Carrying out man-machine command when mutual, normally on touch-screen, showing a dummy keyboard, this dummy keyboard shows keyboard layout on screen, accepts writing pencil or finger input or wait through pointing apparatus such as mouse to import through touching device.
Fig. 1 is a kind of demonstration synoptic diagram of dummy keyboard commonly used.Referring to Fig. 1; In general, said dummy keyboard comprises a plurality of keys position, and a said key position is meant a virtual key that on screen, shows; All corresponding main body character on each key position; The all corresponding key position of each English alphabet as shown in Figure 1, the English alphabet on each key position is exactly the main body character of this key position, touches any key position of click and then can import the main body character on this key position.But, because the restriction of the size of touch-screen causes the key number of dummy keyboard that certain restriction is arranged, and need the character quantity of input many especially at present, depend merely on and utilize the mode of the corresponding main body character in a key position can not import all characters fully.Therefore occur the input method of several kinds of characters at present, be used to utilize the touch-screen of finite size to import more character.
Prior art one, on the acquiescence panel of dummy keyboard, show the button of main character; And demonstration switching key; Touch and click then this switching key corresponding characters panel of demonstration on touch-screen of this switching key; This character panel can show the button of additional character, touch to click corresponding button and then imports corresponding auxiliary symbol, if click this switching key once more then can make touch-screen switch back the acquiescence panel of dummy keyboard.In this way, can more different types of characters and switching key be mapped, the corresponding panel that contains a plurality of character keys of switching key, thus can utilize the touch-screen of finite size to import more character equally.
Prior art two, (described button is meant the virtual key on the dummy keyboard at the button of main body character; Also can be referred to as the key position) the last character that performs of assisting that increases; The main body character of button 101 for example shown in Figure 1 is a letter " T "; The auxiliary character that performs is " 5 ", imports the character that performs through long the switching by this button or through a shift temporarily usually.For example said shift is generally SHIFT key 102, directly touches click keys 101 meeting input alphabets " T ", clicks a SHIFT key 102 earlier, and clicking said button 101 again can the input said character that perform " 5 ".In this way, on a button, just can gather the input of two kinds of characters, thereby utilize the touch-screen of finite size to import more character.
Prior art three, one Chinese patent application number are 03128952, open (bulletin) number is in one piece of patented claim document of 1553303; Disclose a kind of through import the method for corresponding character at the different directions layout kinds of characters of virtual key and through ruling; In this method; Each virtual key all comprises a main body character and four additional characters all around; Directly touch and click certain button and can import the corresponding main body character of this button, if but from a button to the operation of ruling of another button, then can import in first button and second that additional character that button is adjacent.Utilize this mode, can make the integrated more character of each button, thereby can utilize the touch-screen of finite size to import more character.
But above-mentioned prior art is defectiveness all:
In the said prior art one; Need to click switching key earlier and switch to this switching key corresponding characters panel, in this character panel, seek the character of desire input more again, click the button of this character after finding again and import; Not only need carry out twice click action; Wherein also be mingled with one and in new character panel, seeking the searching action of desiring input character, and after having imported character, also need click switching key once more and turn back to the acquiescence panel.Therefore its input efficiency is lower.
Need grow by said button during the operation of said prior art two and could import the corresponding character that performs, need one period stand-by period, have a strong impact on the input efficiency of character; Perhaps the user needs elder generation's click shift to switch to the state of performing, and clicks corresponding key again and could import the corresponding character that performs, and promptly need carry out twice clicking operation and could import the character that performs, and the character input efficiency is lower equally.
Said prior art three has certain convenience property when being used for the click keys formula input mode of traditional dummy keyboard; But when the gesture input method that is used for mainly relying on gesture line mode to carry out the literal input, can produce instruction conflict: for example; In line formula spelling input method; The user can slip over specific letter key continuously through gesture and come input Pinyin, slidingly inputs gesture for one, for example in keyboard layout shown in Figure 1, draws to " E " key from " R " as the user; The phonetic that this gesture input method will identify the preparatory input of user is " RE "; Be this input gesture equally, for the scheme that prior art three is disclosed, then can't confirm the user be on earth want input Pinyin " RE " still to import with " E " key on additional character " 3 " still import the additional character " 4 " on " R " key; Therefore, the mode of this input character is used to rely on the input method of gesture input characters to have the defective of tangible input instruction conflict.Simultaneously, the method for this dependence line direction judgement incoming symbol can only be laid a symbol in same direction, reduces input efficiency otherwise can produce repeated code.

The projection dummy keyboard.
Among the following embodiment, mainly with said operation format for said human-computer interaction device is operated through touch-screen, said keyboard is that the dummy keyboard that shows on the said touch-screen is an example, and method and apparatus of the present invention is described.
As shown in Figure 3, in an embodiment of the present invention, an auxiliary input instruction district is set on the dummy keyboard of screen displaying; Suppose that this auxiliary input instruction district is set to the SHIFT button 302 in left side, and on said dummy keyboard, show a plurality of additional characters, said additional character is arranged on the letters case of master keypad; Letter on the said letters case is the main body character; Except that the main body character, also be furnished with the character that performs on each letters case, for example the main body character of letters case 301 is a letter " T "; The auxiliary character that performs is " 5 " in the lower left corner, key position, performs character in like manner on other letters case.The what is called character that performs; Normally for the main body character on being arranged in button; Usually the acquiescence input operation only can be imported the main body character when clicking, and the character that performs need combine other supplementary meanss such as prior art pass through long by or mode such as shift switching import.Among the present invention; The said character that performs is exactly a kind of additional character; Because the size of touch-screen is limited, and need the character quantity of input many, therefore a main body character is set on a key position; And one even the plural character that performs are set simultaneously, to practice thrift the display size of dummy keyboard.In the present embodiment, need set up said auxiliary input instruction district is the incidence relation between SHIFT button 302 and the said a plurality of additional character.
As shown in Figure 3, with the SHIFT button as auxiliary input instruction district, digital 0-9 and ", " "; " wait punctuation mark as auxiliary symbol; said SHIFT key and said auxiliary meeting establish incidence relation; this design, compare with the mode of prior art three described line input characters, can avoid the gesture ambiguity; also improved the utilization ratio of button, effectively practiced thrift mini-plant by bond space.
Certainly, among the present invention, when the SHIFT key is used as auxiliary input instruction district; Conventional clicking operation for the SHIFT shift can adopt common response mode, switches like capital and small letter temporarily; The interim button input of symbol etc. of performing also can be adopted other modes, and the present invention does not do and gives unnecessary details.
Like numeral among Fig. 3 and punctuation mark.In normal input, each alphabet key is represented the main body character, when detecting the user and draw to the G key from the SHIFT key in left side, incoming symbol ".", similarly want input digit 1, in input process, need interim input digit, can directly draw " Q key " to numeral 1 place from the SHIFT key.
The concrete grammar of the input gesture on the said senses touch screen; Can adopt existing known detection technique; For example the operating system of electronic equipment such as smart mobile phone can be responded to the input action of user on touch-screen; Whenever sense an input action and then can send an action message; As long as method and apparatus of the present invention utilizes the API (API) of operation system of smart phone to detect said action message, said action message discerned just can detect the input gesture of user on touch-screen.
Among the present invention, what need to detect is to be the input gesture that beginning or end is rule with said auxiliary input instruction district.This imports gesture, both can be to be starting point with said auxiliary input instruction district, to additional character direction line to be imported, perhaps also can be to be that starting point is to auxiliary input instruction ride from additional character to be imported or other position.But said auxiliary input instruction district must be the beginning or end of said line operation, if the starting point and the terminal point of said line operation all are said auxiliary input instruction districts, and the operation of input additional character that then can triggering following.
Detect with said auxiliary input instruction district be the beginning or end input gesture of ruling after, need confirm that then which additional character the additional character of final desire input is.Method of the present invention such as step 202 are said, that is: according to another end points of this line with should auxiliary input instruction district the position relation of related additional character, confirm corresponding desire input additional character, import determined additional character.
Another end points of said line is exactly and that relative end points of said auxiliary input instruction district, if when said auxiliary input instruction district is the starting point of said line, then another end points of said line is the terminal point of this line; If when said auxiliary input instruction district was the terminal point of said line, then another end points of said line was the starting point of this line.
Among the present invention, said another end points according to this line with should auxiliary input instruction district the position relation of related additional character confirm that corresponding desire imports additional character two kinds of concrete modes can be arranged:
The concrete mode of first kind of definite desire input additional character comprises:
At first obtain the residing key of another end points of said line position;
Judge then said key position whether be with said auxiliary input instruction district as the line beginning or end the related residing key of additional character position; If, then with on this key position with said auxiliary input instruction district as the line beginning or end related additional character confirm as desire input additional character.
Corresponding; In character entry apparatus of the present invention; Said additional character load module specifically is used for: the incidence relation between said auxiliary input instruction district and the said additional character is set; Input gestures detection module detect with said auxiliary input instruction district be the beginning or end input gesture of ruling after; Obtain the residing key of another end points of said line position; Judge said key position whether be with said auxiliary input instruction district as the line beginning or end the related residing key of additional character position, if, then with on this key position with said auxiliary input instruction district as the line beginning or end related additional character confirm as desire input additional character.
For example; In dummy keyboard shown in Figure 3; Rule to said letter key G for starting point if detect the user and from said auxiliary input instruction district be SHIFT key 302, the terminal point of this line is letter key G, has represented the line track of this line input gesture like the dotted line 303 of the band arrow among Fig. 3.Utilize method and apparatus of the present invention can obtain the key position of this line terminal point here; It is the key position of letter key G; The key position of judging this letter key G then whether be with said auxiliary input instruction district 302 as the line starting point the related residing key of additional character position since here the said additional character on the key position "." set up incidence relation with auxiliary input instruction district 302, therefore, desire input additional character confirmed as in the additional character on this key position, and import this additional character ".”。
Again for example; In dummy keyboard shown in Figure 3; If detecting the user is that starting point is 302 line of SHIFT key to said auxiliary input instruction district from letter key R, the terminal point of this line is a SHIFT key 302, has represented the line track of this line input gesture like the dotted line 304 of the band arrow among Fig. 3.Utilize method and apparatus of the present invention can obtain the key position of this line starting point here; It is the key position of letter key R; The key position of judging this letter key R then whether be with said auxiliary input instruction district 302 as the line terminal point the related residing key of additional character position because the said additional character " 4 " on the key position has been set up incidence relation with auxiliary input instruction district 302 here, therefore; Desire input additional character confirmed as in additional character on this key position, and import this additional character " 4 ".
The concrete mode of second kind of definite desire input additional character comprises:
At first, obtain the position coordinates of said another end points of line;
Then, obtain with said auxiliary input instruction district as the line beginning or end related additional character residing key position or position coordinates;
Then; From said auxiliary input instruction district as the line beginning or end the related additional character; Confirm a nearest additional character of its key of living in position or position and said another endpoint location of line, desire input additional character confirmed as in this additional character.
Corresponding; In character entry apparatus of the present invention; Said additional character load module specifically is used for: the incidence relation between said auxiliary input instruction district and the said additional character is set; Input gestures detection module detect with said auxiliary input instruction district be the beginning or end input gesture of ruling after; Obtain the position coordinates of said another end points of line, obtain with said auxiliary input instruction district as the line beginning or end related additional character residing key position or position coordinates, from said auxiliary input instruction district as the line beginning or end the related additional character; Confirm a nearest additional character of its key of living in position or position and said another endpoint location of line, desire input additional character confirmed as in this additional character.
The said second way can not be accurate to specifically when comprising the key position of additional character at the rule end points of gesture of user, can realize the input to corresponding additional character yet, and certain error correcting capability is promptly arranged.For example, in Fig. 3, shown in the dotted line 305 of band arrow represented the once line track of line input gesture; In this line input gesture; Said auxiliary input instruction district is that SHIFT key 302 is starting point, and terminal point is below letter key N, does not drop on any key position.At this moment; Can obtain the position coordinates of this terminal point according to the said second way; Obtain again with said SHIFT key 302 the related residing key of additional character position, therefrom confirm the nearest additional character of its key of living in position and said line final position coordinate then, for example the key position of letter key N and this terminal point of ruling are nearest here; Then " (" confirmed as desire input additional character, and input " (" with the additional character on the key position of this letter key N.
Otherwise if the line track is just in time in the opposite direction with the line of said line track 305, the line terminal point of promptly said line track 305 becomes the line starting point; Said SHIFT key 302 becomes the line terminal point; Then in like manner, obtain the position coordinates of this line starting point, obtain again with said SHIFT key 302 the related residing key of additional character position; Therefrom confirm a nearest additional character of its key of living in position and said line start position coordinate then; For example the key position of letter key N and this line starting point are nearest here, and then " (" confirmed as desire input additional character, and input " (" with the additional character on the key position of this letter key N.
If said additional character is not positioned on the key position, but be positioned at other position of dummy keyboard, for example shown in Figure 4, said additional character is between the key position of said dummy keyboard, then utilizes the above-mentioned second way to confirm desire input additional character.For example, in Fig. 4, suppose that said all additional characters all have incidence relation with said auxiliary input instruction district SHIFT key 302; Shown in the dotted line 401 of band arrow represented the once line track of line input gesture, in this line input gesture, said auxiliary input instruction district is that SHIFT key 302 is starting point, terminal point is between letter key F and letter key G.At this moment, can obtain the position coordinates of this terminal point according to the said second way, obtain again with said SHIFT key 302 the related residing position coordinates of additional character; Therefrom confirm a nearest additional character in its present position and said line final position then, for example position and this terminal point of ruling of additional character ", " here is nearest; Then with this additional character "; " Confirm as desire input additional character, and input ", ".
