Description
Technical field
The present invention relates to writing technology field, particularly a kind of full frame handwriting recognition input method andSystem.
Background technology
As the simple and convenient and efficient input mode of one, handwriting input has changed traditional based on multipleThe keyboard mode of assorted coding or Pinyin Input is the man-machine interaction of the Natural humanity condition of providing convenience. SpecialNot that handwriting input seems particularly important on the small screen portable intelligent terminal device. But traditional limittingIt is not too convenient that the handwriting input mode of determining to write in region seems on small screen device, particularly in recent yearsFast-selling iphone etc. refer to get an electric shock and hold on screen equipment, and the range of movement of finger input is larger than writing pencil, moreBe not easy input fast in localized area.
For this reason, researcher has proposed the scheme based on full frame handwriting input, allows user at whole screenFree Writing, and be no longer confined to legacy system default determine write region. In full frame handwriting inputUnder pattern, user can input optional position in screen space, has further expanded and has write region, changesBe apt to the writing experience on small screen device. But full frame handwriting input mode screen space is set to penMark input area, has shielded the possible application program operational order of user, specifically applies to user and backstageProgram interaction has brought trouble. As in short message editing application, when user version complete needs a little of inputHit " transmission " button and send when message, because input method has been intercepted and captured user instruction, cause application program withoutMethod is accepted user instruction.
In order also can to respond user's application program instructions, conventional method under full frame handwriting input modeSelect directly to exit input method receiving after index signal, manipulation is weighed and transferred to backend applications to connectBe subject to the control of user to backend applications. The clicking operation of user to text edit box detected subsequentlyRear re invocation input method. Fig. 1 and Fig. 2 have shown that respectively traditional full frame handwriting input mode is " short disappearingBreath " application in active state and exit rear state. Concrete, taking short message editing application program asExample, in the time that user starts short message editing application program and in text edit box, cursor focus is set, isSystem starts full frame input pattern automatically, enters the input method active state shown in Fig. 1, accepts user and existsThe person's handwriting input in full screen region. The command key operation that user is possible ought be detected subsequently, as clickedWhen " transmission " order, system is selected to exit input method and is hidden interface of input method, recovers application program circleFace is accepted user's button operation, as shown in Figure 2.
In addition,, in conventional method, user is often known the cursor location to word in text edit boxWei input method enabled instruction, and re invocation input method affected user's true operation. Therefore,Under full frame input pattern, how rationally to solve rushing of text editing (being mainly cursor location) and character inputProminent is also problem demanding prompt solution. To this, there is researcher to propose to arrange separately cursor control button, asShown in Fig. 3, by realizing text edit box character locating by key control cursor movement. User is at word like thisIn symbol input process if desired to input character editor, by two that control screen middle and upper part and suspendArrow key is removable cursor position, and then deletes or interpolation fresh character.
This control that realizes user's application programs by Temporarily Closed input method, and by arranging separatelyThe text editing of arrow spatial manipulation and the mode of character input conflict, still not too square in actual applicationsJust, be mainly reflected in following several respects:
1. often there is larger difference, phase in input method application and backend applications on interfaceBefore and after input method is closed, also often there is larger variation in the function button layout of user's manipulation of answering. WhenUser, in the time realizing the instruction of " short message transmission ", needs respectively to click the interface of input method shown in Fig. 1In be arranged in the screen that is positioned at of the Application Program Interface shown in " transmission " button and the Fig. 2 in the middle of screen" transmission " button of bottom, has obviously brought inconvenience to the positioning action repeatedly of same button to user.
2. the method for calling of traditional input method is difficult to realize the effective editor to character in text edit box.Such as user during to text string editor, wishes that relevant position is by click side in text edit box at needsWhen formula is inserted cursor, system is often identified as this operation input method enabled instruction or exits input method and refers toOrder, thus user's true operation affected.
3. existing by arrow key being additionally set to control the mode of cursor location in text edit boxIn, first, cursor control button need to be designed to translucent suspension and be marked with and avoid affecting backend application journeyThe button at order interface, is easily subject to the impact of application program background colour, causes in a lot of application user pastToward cannot clearly distinguishing this control position. Secondly, self-existent suspension mark makes the user often can not be justConfirm to know the purposes of this button, easily the control of itself and application program is obscured. Again, fail by key controlUser is provided clear and definite tactile feedback, makes user can not know in time operating conditions. Finally, pass through arrowAlthough the location that button moves cursor can realize word in text editing district, it is to the multiple characters in intervalWhen text location, still need mobile cursor one by one, operation is inconvenience comparatively.
