Embodiment
Hand-written inputting method alleged by the present invention, intelligent terminal realizes in a software form, can run in various hardware device, the terminal type equipment such as such as smart mobile phone, panel computer, intelligent television, game machine.User can carry out handwriting input by finger or pen on touch-screen or handwriting pad, in addition can also by contactless mode as the input characters before camera that uses gesture.
Fig. 1 is the example schematic of hand input device of the present invention.Hand input device in the present embodiment, comprises input block 1, is mainly used to receive hand-written operation input; Recognition unit 2, can identify the handwriting that input block 1 obtains; Detecting unit 3, can detect in input process and calculate the change in location of touch point, if amplitude of variation before the first Preset Time is compared in predeterminable range in current touch point position, terminate handwriting input operation, by recognition unit 2, identify the handwriting of input, otherwise continue to receive hand-written operation input by input block 1.
Detecting unit 3 can also comprise a dead time variable 7, detects touch event, if occur to touch moving event, then by dead time variable zero setting; If detect it is touch the state pressed always, namely the change in location amplitude of touch point is zero, then the accumulative described dead time, when detecting that the accumulative dead time exceedes Preset Time, then confirms to terminate this handwriting input operation.
Hand input device can also comprise control module 4, and after the handwriting starting identification input, the handwriting of the upper display that clears screen, resets handwriting input state, show the word candidate list obtained according to handwriting recognition results.
If there is the second Preset Time after touching event of lifting in input process after, detecting unit 3 does not detect that touch is pressed event and occurred, then terminate handwriting input operation, start by recognition unit 2 to identify the handwriting of input.
The all right involving vibrations unit 5 of hand input device, for when terminating this handwriting input operation, produces of short duration slight vibrational feedback signal.Hand input device also can also comprise pronunciation unit 6, for after the handwriting of recognition unit 2 identification input, plays the word pronunciation of recognition result.
Fig. 2 is the main flow schematic diagram of hand-written inputting method example of the present invention, to be embodied as example on the smart mobile phone having touch-screen, comprises the following steps:
201, the hand-written operation input on intelligent terminal for reception touch-screen.User can be inputted on screen by finger, while input, screen shows corresponding person's handwriting.Usually be once input as a character (Chinese or alphabetical etc.) or a word, can comprising multiple stroke, having the of short duration time interval between each stroke when inputting, this time interval within the predetermined time (as 0.5 second), meets the natural input habit of people.
202, in input process, detect and calculate the change in location of touch point.Touch point is along with the continuous change location of stroke of input, and the track of stroke goes on record in input process, is stored in the respective data structures in tag memory.
If 203 detect that amplitude of variation before the first Preset Time is compared in predeterminable range in current touch point position, then perform step 204, terminate handwriting input operation, start the handwriting identifying input.As shown in Figure 3, handwriting input Chinese character " people ", step 301 and 302 inputs continuous print two-stroke respectively successively, in step 303, namely user is after writing a words, after finishing touch completes, finger does not frame out, to pause about of short duration Preset Time (as 100 or 150 milliseconds), at this moment terminal detects pause, namely the change in location amplitude of touch point is less than predeterminable range threshold value (as 25 pixels), then confirm to terminate this handwriting input operation, starts the handwriting identifying input.Position, touch point before current position, touch point and Preset Time can be compared during calculating, ask relative distance, or stricter, according to the path between stroke trajectory calculation two touch points of recording, the change in location amplitude using path as touch point.
Also has the simpler scheme of one, use a dead time variable, touch event is detected, if occur to touch moving event, then by dead time variable zero setting, if be touch the state pressed always, namely the change in location amplitude of touch point is that 0(touch point is not moved), the then accumulative dead time, when detecting that the accumulative dead time exceedes Preset Time, then confirm to terminate this handwriting input operation.
Otherwise, if detect that the amplitude of touch point change in location is comparatively large, then go to step 201, continue to receive hand-written operation input.
In addition after the handwriting starting identification input, the handwriting of the upper display that can clear screen, resets handwriting input state; Show the word candidate list obtained according to handwriting recognition results; And optimal result is presented at the position of current input cursor.If user continues input, then the optimal result of current display is accepted automatically, if user have selected other results at word candidate list, then accepts the content that user selects.
In order to the scheme that compatibility is commonly used at present, allow Consumer's Experience natural transition, can in input process, there is the second Preset Time after touching event of lifting (as 500 milliseconds, general at 300 to 600 milliseconds) after, if do not detect that touch is pressed event and occurred, then terminate handwriting input operation, start the handwriting identifying input.Even if user is after writing word like this, forgets to touch and pause, lifted finger, the end of handwriting input also normally can have been detected, then identify.
After once having inputted, preferably can give user feedback in time, can when terminating this handwriting input operation, terminal produces of short duration slight vibrational feedback signal.The duration of vibration, generally within 500 milliseconds, produces and allows user feel of short duration vibration slightly, should not be long.In addition after the handwriting identifying input, terminal can also play the word pronunciation of recognition result.Pass through cls, vibration and voice like this from vision, each side such as sense of touch and the sense of hearing is fed back timely to user one, can improve reaction velocity and the input efficiency of user.
In addition for the system adopting camera identification handwriting input operation, as intelligent television or video game machine, different from the operation of handset touch panel, usually can carry out inputting and identifying with the movement locus of whole palm, and be inputted by finger unlike mobile phone.By camera identification, although there is no actual contact, can detect whether the movement locus of palm pauses equally.Therefore, in input process, can detect and calculate the change in location of palm; If after the first Preset Time, the amplitude of variation of palm position, in predeterminable range, terminates handwriting input operation, starts the handwriting identifying input; Otherwise continue to receive hand-written operation input.Visible such scheme and inventive touch shield the embodiment realized and there is no essential distinction technically.
Above disclosedly be only preferred embodiment of the present invention, certainly can not limit the interest field of the present invention with this, therefore according to the equivalent variations that the present patent application the scope of the claims is done, still belong to the scope that the present invention is contained.
