Embodiment
Enforcement to technical scheme will describe in further detail in conjunction with the accompanying drawings below.A kind of single-hand input method and device:
Comprise with lower module: acceleration transducer is used to detect input trajectory data high up in the air; Application processor comprises, the track algoritic module be used to accept the input trajectory data high up in the air that acceleration transducer transmits, and the input trajectory data conversion of will soaring aloft is discernible stroke trace information; Track judge module: be used for judging stroke information according to the stroke trace information; Character library character retrieval module: retrieve satisfactory font etc. after the character library information comparison that is used for to preset in stroke information and the storer; Storer is used for application storing, information such as stroke, character library; Man-machine interactive system comprises touch-screen, keyboard etc.
Fig. 1 is system's connection layout of the singlehanded input media of the specific embodiment of the invention.Singlehanded input media comprises acceleration transducer, the communication interface of transmitting input trajectory data high up in the air, application processor, display screen and final required keyboard or the touch-screen of man-machine interaction.Behind the selected input pattern high up in the air of user, can directly do writing of any reference planes, as desktop, metope etc. or a virtual plane high up in the air with terminal.Be input as example with Chinese character, when hand-written, acceleration transducer passes to application processor with detected input trajectory data high up in the air by communication interface (as the I2C interface), track algoritic module in the application processor takes the lead in handling, the input trajectory data conversion of will soaring aloft is discernible stroke trace information, by the internal processes interface stroke trace information is passed to the track judge module then, what stroke judges is, for example " horizontal stroke " " erects " " left-falling stroke " " right-falling stroke " etc.; The stroke of judging is kept in the storer, and character library character retrieval module is judged the font of importing according to the sequence of stroke input, by the LCD interface on the application processor character is shown at display screen at last, and the user confirms by keyboard or touch-screen.Identification for input trajectory data high up in the air can relate to a precision problem.This precision is to be decided by the digital to analog converter in the acceleration transducer (ADC).The data b it position of ADC is many more, and the information that can detect is just accurate more.Present embodiment adopts the 8bit sensor of main flow.
Fig. 2 is the introduction figure of the strokes sequence input (is example with " word eight treating observances forever ") of specific embodiment of the invention single-hand input method.As shown in the figure, " forever " word can be broken down into " point " " horizontal stroke " and " erects " " hook " and " carry " " left-falling stroke " " short cast aside " " right-falling stroke " eight strokes.Like this, can find " forever " word as long as when hand-written, import these eight strokes in order respectively.Because the retrieval of this input method only relies on strokes sequence, size between stroke and the stroke and position relation are left in the basket, and overlappingly also can discern even spatially have during input, so be particularly suitable for application of writing high up in the air.Based on this input method, draw the character that meets current strokes sequence and meet current strokes sequence but also contain the character of other follow-up strokes sequences, as the stroke input method that uses keyboard, make things convenient for the user to be familiar with using.
Fig. 3 is the introduction figure of the hand-written phonetic input of specific embodiment of the invention single-hand input method.In fact the input of phonetic is exactly the input of English alphabet.The identification of English alphabet is fairly simple, and 26 letters nearly all can one have been write, the user is high up in the air write a letter after, terminal finds the letter that is close with track to select for the user in alphabetical storehouse according to the track of writing.A string phonetic input is finished, and the man that character library will meet this string phonetic lists the selection for the user.For example import " sheep " this word, choose letter " y " behind the 1st step handwriting trace, the 2nd step handwriting trace is chosen letter " a ", the 3rd step handwriting trace is chosen " n ", the 4th step handwriting trace is chosen " g ", and the 5th step listed the Chinese character that meets this pronunciation and selects for the user according to the phonetic " yang " of input.End user clicks and chooses " sheep ".
Specific embodiment of the invention single-hand input method process:
The first step, the user opens inputting interface, selects input pattern high up in the air;
In second step, state is adjusted in the acceleration transducer initialization, prepares to receive data;
In the 3rd step, the user begins hand-written, and the raw data of acceleration transducer reports the track algoritic module in the application processor;
In the 4th step, the track algoritic module carries out information processing to input trajectory data high up in the air, and which kind of stroke what the track judge module was judged input is.Here need to specify down the basis for estimation of stroke.To write one " point " is example.Input trajectory high up in the air is a three-dimensional track, so passing to the data of application processor should be the acceleration of a three-dimensional, but it is actual when hand-written, the font of writing all is two-dimentional, needs first travel direction to distinguish and the virtual plane mapping, at first, the establishment of virtual plane, regard the face at terminal place as a plane ignore its thickness, acceleration transducer is regarded a point as, and is perpendicular and promptly can be used as hand-written virtual plane through the plane of acceleration transducer with the terminal plane; Secondly, the input trajectory data map of will soaring aloft becomes the stroke trace information, acceleration transducer itself just can detection angles, after virtual plane is established, acceleration transducer carries out the triangle cosine function again and handles by detecting the three-dimensional track data of importing high up in the air and the angle of virtual plane, is mapped to the stroke trace information, according to direction and the stroke trace information that maps out, obtaining the first stroke is " point ".
The 5th goes on foot, and the stroke of judging is delivered in the storer preserved.
The 6th step, stroke is read from storer, in character library, compare.Hit and then list the word that meets current strokes sequence, do not have and hit then this handwriting input end.
In the 7th step, the output that the character that searches is real-time is selected for the user on display screen.
In the 8th step, the user does not select, and just prepares to carry out the detection of next stroke.The user selectes a character, and this handwriting input finishes.
To write " forever " word is example, specifically the input of font once.The first stroke falls, and track judge module program judges that according to direction and the track that maps out obtaining the first stroke is " point ".In the output of character library, will list all the first strokes in real time is the words of " point ".Write second then, during user's daily writing, the intact process that has " fermenting " between not going out of row is to select starting to write a little of stroke.Do you how to judge that dragging of terminal is that " fermenting " still starts to write? Chinese writes, and what stroke the inside was stressed is to accomplish without any letup, so write stroke and a row when intact, acceleration can obviously increase.For example, begin to write one " horizontal stroke ", pen is write across the page out to one from static, and acceleration can be very big; Same, one has write across the page, and is classified as staticly, and a very big acceleration is also arranged.Like this, one stroke can detect up to just finishing from beginning.The process of " fermenting " can be considered in conjunction with two factors: whether the track of writing is the stroke stipulated in the character library and a first stroke of a Chinese character acceleration magnitude when stopping.If track in the stroke scope of character library regulation, is not given up; If in scope, acceleration is set a threshold value, detect acceleration and just be judged as the stroke input, less than then being classified as " fermenting " greater than this threshold value.Choosing of threshold value will be passed through user experience, and one acceleration comes value when writing according to most users (at least 98%).By that analogy, write " forever " word from the first stroke up to the 8th.
By acceleration transducer is carried out new function development, make the terminal one hand just can finish hand-written operation.Enriched the diversity of user's input.In actual life, many application scenarioss can be arranged, carry personal letter of dish such as a hand and write; It is many that the disabled person of only hand uses handwriting functions to make things convenient for; Perhaps open-air in danger, the injured or fixing health of hand, the another personal letter is write emergency note or the like.
The above is the preferred embodiments of the present invention only, is not limited to the present invention, and for a person skilled in the art, the present invention can have various changes and variation.Within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
