Current human-computer interaction device is of a great variety, and wherein great majority are the electronic equipments that can receive manual command and carry out documents editing.Especially, the kind at present with the electronic equipment of touch-screen gets more and more, such as, have the computing machine of touch-screen, touch-screen mobile phone, touch-screen palm PC, touch screen flat panel computer etc.Have in the electronic equipment of touch-screen at these, normally utilize touch-screen and electronic equipment to carry out man-machine command alternately, especially operating personnel will utilize touch-screen to instruction or information such as input characters in electronic equipment.
Along with popularizing of touch-screen, very common for the application performing the input gesture of various instruction.When carrying out man-machine command and being mutual, normally show a dummy keyboard on the touchscreen, this dummy keyboard shows keyboard layout on screen, accepts writing pencil or finger input or inputted by indication equipment such as mouse etc. by touching device.
Fig. 1 is a kind of display schematic diagram of conventional dummy keyboard.See Fig. 1, in general, described dummy keyboard comprises multiple key mapping, a described key mapping refers to the virtual key shown on screen, a corresponding main body character in each key mapping, the corresponding key mapping of each English alphabet as shown in Figure 1, the English alphabet in each key mapping is exactly the main body character of this key mapping, and any one key mapping of touch click then can input the main body character in this key mapping.But, because the size of touch-screen limits, cause the key number of dummy keyboard to have certain restriction, and need the character quantity of input many especially at present, depend merely on and utilize the mode of the corresponding main body character of a key mapping can not input all characters completely.Therefore having there is the input method of several character at present, having inputted more character for utilizing the touch-screen of finite size.
Prior art one, on the default faceplate of dummy keyboard, show the button of main character, and show switching key, touch this switching key of click and then show character panel corresponding to this switching key on the touchscreen, this character panel can show the button of additional character, touch and click the auxiliary symbol that corresponding button then inputs correspondence, if again click this switching key, touch-screen can be made to switch back the default faceplate of dummy keyboard.Much more in this way, can be mapped with switching key by more different types of character, a switching key correspondence one contains the panel of multiple character keys, thus the touch-screen of finite size can be utilized equally to input more character.
Prior art two, at the button of main body character, (described button refers to the virtual key on dummy keyboard, also key mapping can be referred to as) above increase the auxiliary character that performs, the main body character of the button 101 such as shown in Fig. 1 is letter " T ", the auxiliary character that performs for " 5 ", usually by long by this button or switch input by a shift and to perform character temporarily.Such as described shift is generally SHIFT key 102, and directly touching click keys 101 can input alphabet " T ", first clicks a SHIFT key 102, then click described button 101 can input described in perform character " 5 ".In this way, a button just can be gathered the input of two kinds of characters, thus utilize the touch-screen of finite size to input more character.
Prior art three, Chinese Patent Application No. is 03128952, open (bulletin) number is in one section of Patent Application Publication of 1553303, disclose a kind of by arranging kinds of characters at the different directions of virtual key and being inputted the method for corresponding character by line, in the method, each virtual key comprises four additional characters of a main body character and surrounding, certain button is clicked in direct touch can input main body character corresponding to this button, if but carry out scribing operation from a button to another button, then can input that additional character adjacent with second button in first button.Profit in this way, can make the integrated more character of each button, thus the touch-screen of finite size can be utilized to input more character.
But, above-mentioned prior art all defectiveness:
In described prior art one, need first to click switching key and be switched to character panel corresponding to this switching key, again the character for input is found again in this character panel, the button clicking this character after finding again inputs, not only need to carry out twice click action, wherein also be mingled with a searching action found in new character panel for input character, and after having inputted character, also need again to click switching key and turn back to default faceplate.Therefore its input efficiency is lower.
Need the long character that performs that could input correspondence by described button during the operation of described prior art two, need one period of stand-by period, had a strong impact on the input efficiency of character; Or user needs first to click shift and is switched to the state of performing, then click the character that performs that corresponding button could input correspondence, namely need to carry out twice clicking operation and could input the character that performs, character input efficiency is lower equally.
Described prior art three has certain convenience when the click keys formula input mode for traditional dummy keyboard, but can instruction conflict be produced when being used for mainly relying on gesture hatched manner to carry out the gesture input method of text event detection: such as, in line formula spelling input method, user can slip over specific letter key continuously by gesture and carry out input Pinyin, gesture is slidably inputed for one, such as when user draws to " E " key from " R " in the keyboard layout shown in Fig. 1, this gesture input method will identify the phonetic of user's pre-entered for " RE ", this input gesture equally, for the scheme disclosed by prior art three, then cannot determine that user wants input Pinyin " RE " still will input and the additional character " 3 " on " E " key or the additional character " 4 " inputted on " R " key, therefore, the defect of mode for relying on the input method of gesture input characters to there is significantly input instruction conflict of this input character.Meanwhile, this method of line walking direction incoming symbol that relies on can only lay a symbol in same direction, otherwise can produce repeated code reduction input efficiency.

Projection virtual keyboard.
Below in embodiment, mainly with described operation format for be operated described human-computer interaction device by touch-screen, described keyboard is the dummy keyboard of described touch screen display is example, is described method and apparatus of the present invention.
As shown in Figure 3, in an embodiment of the present invention, the dummy keyboard of touch-screen display arranges an auxiliary input instruction area, suppose that this auxiliary input instruction area is set to the SHIFT button 302 in left side, and on described dummy keyboard, show multiple additional character, described additional character is arranged on the letters case of master keypad, letter on described letters case is main body character, on each letters case except main body character, also be furnished with the character that performs, the main body character of such as letters case 301 is letter " T ", the auxiliary character that performs is " 5 " in the key mapping lower left corner, other letters case performs character in like manner.What is called performs character, normally for the main body character be arranged on button, usual acquiescence input operation as only main body character can be inputted when clicking, and the character that performs need in conjunction with other supplementary meanss as prior art by long by or the mode such as shift switching input.In the present invention, the described 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 in a key mapping, and an even plural character that performs is set simultaneously, to save the display size of dummy keyboard.In the present embodiment, need to set up described auxiliary input instruction area and the incidence relation between SHIFT button 302 and described multiple additional character.
As shown in Figure 3, using SHIFT button as auxiliary input instruction area, digital 0-9 and ", " "; " etc. punctuation mark as auxiliary symbol; described SHIFT key and described auxiliary meet set up relevant; this design; the mode with the line input character described in prior art three is compared; gesture ambiguity can be avoided; also improve the utilization ratio of button, effectively saved mini-plant by bond space.
Certainly, in the present invention, when SHIFT key is used as auxiliary input instruction area, for the conventional clicking operation of SHIFT shift, common response mode can be adopted, as capital and small letter switches temporarily, perform the interim key-press input etc. of symbol, and also can adopt other modes, the present invention does not repeat.
As the numeral in Fig. 3 and punctuation mark.When normal input, each alphabet key represents main body character, in time detecting that the SHIFT key of user from left side is drawn to G key, incoming symbol ".", similar will input numeral 1, needs to input numeral temporarily, directly can draw " the Q key " to digital 1 place from SHIFT key in input process.
The concrete grammar of the input gesture on described detection touch-screen, existing known detection technique can be adopted, such as electronic equipment such as the operating system of smart mobile phone can respond to user's input action on the touchscreen, often sense that an input action then can send an action message, as long as method and apparatus of the present invention utilizes the application programming interface of operation system of smart phone, (API) detects described action message, carries out identifying just detecting user's input gesture on the touchscreen to described action message.
In the present invention, what need to detect is for beginning or end carries out the input gesture of ruling with described auxiliary input instruction area.This input gesture both can be with described auxiliary input instruction area for starting point, to additional character direction to be entered line, or also can be that starting point is rule to auxiliary input instruction area from additional character to be entered or other position.But described auxiliary input instruction area must be the beginning or end of described scribing operation, if the starting point of described scribing operation and terminal are all described auxiliary input instruction areas, then can not the operation of input additional character of triggering following.
After detecting and carrying out the input gesture of ruling with described auxiliary input instruction area for beginning or end, then need to determine which additional character the final additional character for input is.Method of the present invention as described in step 202, that is: according to another end points of this line and this auxiliary position relationship input additional character associated by instruction area, being determined corresponding to inputting additional character, being inputted determined additional character.
Another end points of described line is exactly that end points relative with described auxiliary input instruction area, if when described auxiliary input instruction area is the starting point of described line, then another end points of described line is the terminal of this line; If when described auxiliary input instruction area is the terminal of described line, then another end points of described line is the starting point of this line.
In the present invention, with this auxiliary position relationship input additional character associated by instruction area, described another end points according to this line determines that corresponding wish inputs additional character and can have two kinds of concrete modes:
The first determines to comprise for the concrete mode of input additional character:
First the key mapping residing for another end points of described line is obtained;
Then judge described key mapping whether for the key mapping residing for the additional character associated by the described auxiliary input instruction area as beginning or end of ruling, if so, then using being defined as inputting additional character with the additional character associated by the described auxiliary input instruction area as beginning or end of ruling in this key mapping.
Corresponding, in character entry apparatus of the present invention, described additional character load module specifically for: the incidence relation between described auxiliary input instruction area and described additional character is set, detect with described auxiliary input instruction area as after beginning or end carries out the input gesture of ruling in input gesture detection module, obtain the key mapping residing for another end points of described line, judge described key mapping whether for the key mapping residing for the additional character associated by the described auxiliary input instruction area as beginning or end of ruling, if, then using being defined as inputting additional character with the additional character associated by the described auxiliary input instruction area as beginning or end of ruling in this key mapping.
Such as, in the dummy keyboard shown in Fig. 3, if detect that user rules to described letter key G from described auxiliary input instruction area and SHIFT key 302 for starting point, the terminal of this line is letter key G, and the dotted line 303 as the band arrow in Fig. 3 illustrates the line track of this line input gesture.Utilize method and apparatus of the present invention can obtain the key mapping of this line terminal herein, the i.e. key mapping of letter key G, then the key mapping judging this letter key G whether for the key mapping residing for the additional character associated by the described auxiliary input instruction area 302 as starting point of ruling, due in key mapping herein described additional character "." input instruction area 302 establish incidence relation with auxiliary, therefore, the additional character in this key mapping is defined as inputting additional character, and input this additional character ".”。
Again such as, in the dummy keyboard shown in Fig. 3, if detect that user is that starting point is rule to described auxiliary input instruction area and SHIFT key 302 from letter key R, the terminal of this line is SHIFT key 302, and the dotted line 304 as the band arrow in Fig. 3 illustrates the line track of this line input gesture.Utilize method and apparatus of the present invention can obtain the key mapping of this line starting point herein, the i.e. key mapping of letter key R, then the key mapping judging this letter key R whether for the key mapping residing for the additional character associated by the described auxiliary input instruction area 302 as terminal of ruling, because the described additional character " 4 " in key mapping herein inputs instruction area 302 establish incidence relation with auxiliary, therefore, additional character in this key mapping is defined as input additional character, and inputs this additional character " 4 ".
The second is determined to comprise for the concrete mode of input additional character:
First, the position coordinates of described another end points of line is obtained;
Then, obtain and the key mapping residing for the additional character associated by the described auxiliary input instruction area as beginning or end of ruling or position coordinates;
Then, from described as line beginning or end auxiliary input instruction area associated by additional character, determine a nearest additional character of key mapping residing for it or position and described another endpoint location of line, this additional character is defined as input additional character.
Corresponding, in character entry apparatus of the present invention, described additional character load module specifically for: the incidence relation between described auxiliary input instruction area and described additional character is set, detect with described auxiliary input instruction area as after beginning or end carries out the input gesture of ruling in input gesture detection module, obtain the position coordinates of described another end points of line, obtain and the key mapping residing for the additional character associated by the described auxiliary input instruction area as beginning or end of ruling or position coordinates, from described as line beginning or end auxiliary input instruction area associated by additional character, determine a nearest additional character of key mapping residing for it or position and described another endpoint location of line, this additional character is defined as input additional character.
The described second way can user rule the end points of gesture be not accurate to concrete comprise the key mapping of additional character time, also can realize the input to corresponding additional character, namely have certain error correcting capability.Such as, in figure 3, the dotted line 305 of shown band arrow illustrates the line track of once line input gesture, in this line input gesture, described auxiliary input instruction area and SHIFT key 302 are starting point, and terminal is in the below of letter key N, does not drop in any key mapping.Now, the position coordinates of this terminal can be obtained according to the described second way, obtain again and the key mapping residing for additional character associated by described SHIFT key 302, then a nearest additional character of key mapping residing for it and described line final position coordinate is therefrom determined, such as herein the key mapping of letter key N and this line terminal nearest, then by the additional character in the key mapping of this letter key N, " (" is defined as input additional character, and inputs " (".
Otherwise, if line track is just in time contrary with the line direction of described line track 305, namely the line terminal of described line track 305 becomes line starting point, described SHIFT key 302 becomes line terminal, then in like manner, obtain the position coordinates of this line starting point, obtain again and the key mapping residing for additional character associated by described SHIFT key 302, then a nearest additional character of key mapping residing for it and described line start position coordinate is therefrom determined, such as herein the key mapping of letter key N and this line starting point nearest, then by the additional character in the key mapping of this letter key N, " (" is defined as input additional character, and input " (".
If described additional character is not positioned in key mapping, but be positioned at other position of dummy keyboard, such as, shown in Fig. 4, described additional character is between the key mapping of described dummy keyboard, then utilize the above-mentioned second way to determine for input additional character.Such as, in the diagram, suppose that described all additional characters all have incidence relation with described auxiliary input instruction area SHIFT key 302; The dotted line 401 of shown band arrow illustrates the line track of once line input gesture, and in this line input gesture, described auxiliary input instruction area and SHIFT key 302 are starting point, and terminal is between letter key F and letter key G.Now, the position coordinates of this terminal can be obtained according to the described second way, obtain again and the position coordinates residing for additional character associated by described SHIFT key 302, then therefrom determine a nearest additional character in its present position and described line final position, position and this line terminal of such as additional character ", " are herein nearest, then by this additional character "; " be defined as input additional character, and input ", ".
Otherwise, if line track is just in time contrary with the line direction of described line track 401, namely the line terminal of described line track 401 becomes line starting point, described SHIFT key 302 becomes line terminal, then in like manner, obtain the position coordinates of this line starting point, obtain again and the position coordinates residing for additional character associated by described SHIFT key 302, then a nearest additional character of its present position and described line start position is therefrom determined, such as additional character herein ", " position and this line starting point nearest, then by this additional character ", " be defined as input additional character, and input ", ".
Certainly, in the concrete mode that described the second is determined for input additional character, likely there will be another end points of described line and the key mapping residing for described additional character or position coordinates all far away, as shown in the dotted line 402 of the band arrow of Fig. 4, this line track is probably a kind of maloperation of user.Therefore determine at described the second in another concrete mode of wish input additional character, described from described as line beginning or end auxiliary input instruction area associated by additional character, determine a nearest additional character of key mapping residing for it or position and described another endpoint location of line, can also specifically comprise:
