Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that is obtained under the creative work prerequisite.
Embodiments of the invention provide a kind of hand-written inputting method, as shown in Figure 1, specifically can comprise the steps:
Particularly, can be by an instruction of opening handwriting input as the signal that starts handwriting input, for example on electronic equipment, can be by touching ad-hoc location, pressing specific keys as the signal that starts handwriting input.When electronic equipment receives this enabling signal, enter the handwriting input state.
Particularly, a three dimension acceleration sensor can be set in electronic equipment, be used for the motion state of perception electronic equipment.Under the handwriting input state of electronic equipment, when electronic equipment is moved, the moving parameter information (can comprise moving direction and translational speed) that produces in the moving process is sampled, and can calculate the distance that acquisition is moved according to the traveling time that the corresponding clock unit obtains.
Further, in the process that the moving parameter information that produces in to moving process is sampled, described two-dimensional directional can be defined as the motion track and the parallel plane direction of first coordinate system of electronic equipment, and the user handheld device of described first coordinate system when receiving the instruction of described unlatching handwriting input is perpendicular or parallel; The described electronic equipment that obtains comprises in the moving parameter information on the two-dimensional directional: (described mobile speed is a relative velocity to obtain the speed that electronic equipment moves at two-dimensional directional in described first coordinate system, can think that the translational speed of electronic equipment is zero this moment), and obtain the distance that described electronic equipment moves in described first coordinate system according to the Time Calculation that moves at two-dimensional directional; Described candidate's input character according to described moving parameter information Recognition correspondence comprises: determine that according to described distance a plurality of time points determine described electronic equipment residing positional information in described first coordinate system, determine described candidate's input character according to described positional information.
Determined the position of electronic equipment at described a plurality of time points, just can determine the movement locus of electronic equipment during this period of time, time point is chosen many more, and it is accurate more that track is judged.
In addition, the state in the time of electronic equipment can also being opened the input application is defined as virgin state, and it can be short message editing that described input is used, the handset applications that business card input etc. need be imported.For example shown in Figure 2 is exactly a kind of reference frame vertical with the character display interface of electronic equipment, when opening the input application, can trigger the unlatching three dimension acceleration sensor.For input operation, in the time of can thinking that opening input uses, the relative velocity of handheld device is zero, produces speed a when three dimension acceleration sensor detects electronic equipment respectively in X-axis and Y-axis
xWith speed a
yVariation the time, obtain the distance that moves respectively in X-axis and Y-axis according to the Time Calculation that changes, and be converted into the coordinate in reference frame.
And, to the electronic equipment input character time, once generally all can import a plurality of characters, because character of input needs a stroke or a plurality of stroke, also need a plurality of strokes and import a plurality of characters, therefore can determine that with a predetermined move mode input finishes in each character input finishing back, and, for example move around fast, electronic equipment is revolved three-sixth turn or electronic equipment is left standstill the some time etc. electronic equipment is short-range the moving parameter information of the generation of this predetermined way before moving moving parameter information as a described character correspondence.
Particularly, can discern the moving parameter information (coordinate in described first coordinate system) of input, recognition result is presented on the display screen of electronic equipment as the candidate characters that the user imports when inferior operation by existing character recognition software.Corresponding recognition result corresponding characters in electronic equipment can comprise English, numeral, Chinese character, other language or specific character etc., and these can be stored in the character database of electronic equipment with the recognition result corresponding characters.
In addition, as shown in Figure 3, in the process of the corresponding input character of identification, can comprise step 31, obtain the moving parameter information of electronic equipment on third dimension direction, if the translational speed in the described moving parameter information is non-vanishing, it is invalid to think that then electronic equipment moves the stroke of input; Described third dimension direction is the direction on the definite plane of not parallel described two-dimensional directional.
Particularly, in the process that realizes handwriting input, because the user can not move by the direction in described first coordinate system when mobile electronic device fully, perhaps some user has when writing and has whenever write the custom that a stroke is just started writing, the situation that above situation will cause as shown in Figure 4 moving direction to depart from described first coordinate system occurs, this moment, three dimension acceleration sensor can detect moving on third dimension direction, can neglect the moving parameter information of electronic equipment on the third dimension direction this moment as invalid input, to guarantee the accuracy of input character.And owing to all may have the action of starting writing between a plurality of strokes of a character, therefore the stroke of the starting writing action input between any two effective strokes can be considered to invalid, but the stroke that does not produce third dimension direction moving parameter information should be considered as effectively.
