Specific embodiment
In the prior art, finger or lettering pen are generally used or is write on the touchscreen, then by system detectio
Write result.But, the testing result obtained by current write detection method is not accurate enough.
The present inventor the analysis found that, above mentioned problem it is critical only that current write detection method only for
The overlay area of the word after the completion of writing is detected, and the course bearing of stroke is not embodied in the area of coverage after the completion of font
In domain, cause testing result not accurate enough.
Relative in the prior art, detected according only to the word after the completion of writing, it is impossible to judge the course bearing of stroke
Mistake, causes testing result not accurate enough, in embodiments of the present invention, can be by determining handwriting trace, then according to stroke
Direction it is whether consistent with the direction of pre-stored criteria stroke, judge whether the handwriting trace direction of stroke correct, so as to obtain more
Plus accurate write detection result.
It is understandable to enable above-mentioned purpose of the invention, feature and beneficial effect to become apparent, below in conjunction with the accompanying drawings to this
The specific embodiment of invention is described in detail.
Reference picture 1, Fig. 1 is a kind of flow chart of the write detection method of the electronic copybook in the embodiment of the present invention.It is described
Write detection method can include step S11 to step S13：
Step S11：Change in location according to lettering pen determines handwriting trace, and using continuous handwriting trace as
Stroke.
Step S12：The angle in the direction of the stroke and the direction of pre-stored criteria stroke is calculated, the direction of the stroke is
The vector direction of the starting point to the end of the handwriting trace.
Step S13：If the angle is less than or equal to predetermined angle, it is judged as that the course bearing of the stroke is correct.
In the specific implementation of step S11, with the carrying out of user writing, it may be determined that the track that user currently writes,
For example detected by pressure sensor or infrared inductor and obtained.
Further, using continuous handwriting trace an as stroke.For example when writing words are regular script word, each pen
Picture can be it is horizontal, vertical, skim, right-falling stroke etc. standard stroke, when writing words be disjunctor word, such as during rapid style of writing, each stroke can be with
The corresponding company stroke of font.
Further, lettering pen can be hard-tipped pen or soft pen, such as touch screen pen, writing brush or tactile for putting
Touch finger of screen etc., it is possible to use family is selected according to demand, selection of the present invention to lettering pen is not restricted.
In the specific implementation of step S12, the side of stroke is determined by the vector direction of the starting point to the end of handwriting trace
To, and then calculate the angle in the direction of stroke and the direction of pre-stored criteria stroke.
For example, when user writing stroke " horizontal stroke ", the direction of pre-stored criteria stroke is from left to right, by the side of stroke
To whether user's writing also for from left to right for the stroke can be known, and then calculates the angle between both direction.
In another concrete application, can also for example be existed by determining the relative position of the Origin And Destination of handwriting trace
Lettering pen writes the transverse and longitudinal coordinate for determining Origin And Destination on region with coordinated manner, and then determines the direction of stroke.
In the specific implementation of step S13, if the angle is smaller, it is judged as user's writing for the stroke
Direction is consistent with the direction of pre-stored criteria stroke, namely the course bearing of the stroke is correct.
It is possible to further be less than or equal to predetermined angle according to the angle, it is judged as that stroke presentation direction is correct.As
One nonrestrictive example, can set the angle less than or equal to 10 degree.
Can be multiple blocks by the region segmentation of writing of the lettering pen, in each area in another specific embodiment
In block, the direction of the stroke and the angle in the direction of the pre-stored criteria stroke are calculated respectively.So as to avoid in user only just
The beginning and end of the stroke is really write, but in the case of being made a mistake in the middle of stroke, is still mistaken for the track of stroke
It is in the right direction.
For example, as user writing stroke " ㄋ ", stroke " ㄟ " is written as by mistake, but starting point to the end is in the right direction, then
The course bearing that stroke may be mistaken for is correct.But, if stroke " ㄋ " is divided in multiple blocks, stroke is written as by mistake
" ㄟ " will cause the anisotropy of stroke in Partial Block therein, even without stroke, so that still can be to the stroke
Course bearing make accurate judgment.
Further, carrying out segmentation to writing region can carry out even partition by coordinate, it is also possible to pre-stored criteria
The region of stroke carries out finer division.The embodiment of the present invention is not construed as limiting to the partitioning scheme for writing region.
Further, be more than predetermined angle when finding angle, namely user to the presentation direction of the stroke with prestore
When the direction of standard stroke is inconsistent, user can be made to find mistake in time by way of sending warning and reminding, be more prone to
Corrected.
Specifically, the warning prompting can be word, image, sound etc., specific side of the present invention for warning prompting
Formula is not restricted.
In embodiments of the present invention, can be by determining handwriting trace, the then direction according to stroke and pre-stored criteria pen
Whether the direction of picture is consistent, judges whether the handwriting trace direction of stroke is correct, so as to obtain more accurate write detection knot
Really.
Reference picture 2, Fig. 2 is the flow chart of the write detection method of another electronic copybook in the embodiment of the present invention.Institute
The write detection method for stating another electronic copybook can include step S21 to step S29.
Step S21：Change in location according to lettering pen determines handwriting trace.
Step S22：Calculate the angle in the direction of the stroke and the direction of pre-stored criteria stroke.

Row is performed, and here is omitted.
Step S26：Judge whether that the order between multiple strokes is identical with preset standard order.When judged result is yes
When, step S27 can be performed；Conversely, performing step S24.
At present, write detection method is detected according only to the word after the completion of writing, it is impossible to judge stroke order mistake,
The testing result for obtaining can be caused not accurate enough.Specifically, user is when writing, in addition it is also necessary to come according to certain stroke order
Write, such as " rich " word in Chinese character, the first stroke should be write " one ", and second should write " one ", the 3rd should write
" one ", the 4th should write " ㄧ ", if according to " one, one, ㄧ, one " stroke order write, there occurs mistake, but cannot
Embodied by existing write detection method.
In specific implementation, whether the order that can compare between multiple strokes is identical with preset standard order, if institute
The order stated between multiple strokes is identical with preset standard order, then be judged as that the order between the multiple stroke is correct.
Fig. 3 is a kind of flow chart for implementing of step S26 in Fig. 2, can include step S31 to step S33.
Step S31：All strokes in for each word pre-set stroke sequence number according to Standard Order.
It is that all strokes in each word pre-set stroke sequence number according to Standard Order in specific implementation.For example
Word " big ", can pre-set stroke serial number 1 for " one ", be that " ノ " pre-sets stroke serial number 2, be that " ㄟ " sets in advance
Put stroke serial number 3.
Step S32：Whenever the stroke is received, search the stroke stroke sequence number in the literature.
In specific implementation, stroke stroke sequence number in the literature can be searched according to the stroke for receiving.To write
As a example by word " big ", when stroke " one " is received, stroke serial number 1 of the stroke in word " big " is searched；Receiving
During stroke " ノ ", stroke serial number 2 of the stroke in word " big " is searched；When stroke " ㄟ " is received, the stroke is searched
Stroke serial number 3 in word " big ".
Step S33：If the stroke sequence number of the stroke being sequentially received is continuous, the pen between multiple strokes is judged
Picture order is identical with preset standard order.
In specific implementation, can according to searching " one, ノ, ㄟ " stroke serial number 1,2,3 in the literature, and then according to
Stroke sequence number is continuous, judges that the stroke order between multiple strokes is identical with preset standard order.
In another concrete application, a word there may be multiple identical strokes, such as word " rich ", and preset standard is sequentially
For " one, one, one, ㄧ ", when receiving " one ", stroke sequence number can be " 1,2,3 " in any one.As long as now doubtful pen
Drawing sequence number includes there is successional sequence number with upper unicursal, such as when the 3rd stroke " one " is received, search stroke sequence
Number can be " 1,2,3 ", including sequence number " 3 ", it is possible to be judged as that stroke order is identical with preset standard order.
With continued reference to Fig. 2, in the specific implementation of step S27, it is judged as that the order between multiple strokes is correct.
Relative in the prior art, detected according only to the word after the completion of writing, it is impossible to judge stroke order mistake, lead
The testing result that cause is obtained is not accurate enough, in embodiments of the present invention, can be according to the order between multiple strokes and pre- bidding
Whether quasi- order is consistent, judges whether the order of stroke is correct, so as to realize being detected based on stroke order.Based on the detection
Result is appraised, and the fraction of acquisition also will be more accurate.
Further, when the order between multiple strokes is different from preset standard order, i.e. order between stroke
When writing error, warning can be sent and reminded, so that user has found mistake in time, be more prone to be corrected.
Step S28：Judge whether that stroke is located in the range of predeterminable area.When judged result is to be, step can be performed
Rapid S29；Conversely, performing step S24.
In specific implementation, for each stroke, can respectively judge whether the stroke is located at the scope of predeterminable area
It is interior, if the stroke is located in the range of predeterminable area, it is judged as that the stroke position is correct.
Reference picture 4, Fig. 4 is a kind of flow chart for implementing of step S28 in Fig. 2, can include step S41 to S42.
Step S41：Detect the abscissa scope and ordinate scope of the stroke.
In specific implementation, each specific seat put is determined in transverse and longitudinal coordinate mode on region in can writing for lettering pen
Mark, and then the coordinate set of the stroke is determined according to the overlay area of the stroke, the coordinate set can include horizontal seat
Mark and ordinate.
Step S42：If the abscissa scope of the stroke is located in the range of default abscissa, and the stroke is vertical
Coordinate range is located in the range of default ordinate, then judge that the stroke is located in the range of predeterminable area.
In specific implementation, the scope that default transverse and longitudinal coordinate could be arranged to the transverse and longitudinal coordinate than standard stroke is bigger, when
The coverage of handwriting trace beyond standard letter it is a little when, be not judged as stroke position mistake, so that for user is writing
In freely play and reserve appropriate surplus.Used as a nonrestrictive example, default abscissa may range from the horizontal seat of standard
Mark scope expands 1.1 times, and default ordinate may range from normalized longitudinal coordinate scope and expand 1.1 times.
Further, for complex stroke, it is possible to which a stroke has two or more on same abscissa
It is disjunct, or there is the disjunct point of two or more on same ordinate, the stroke of such as standard stroke " ㄋ " is curved
Near at folding.Now the transverse and longitudinal coordinate of the stroke may range from more than two subranges, if the sub- model of each abscissa
Enclose in the range of default abscissa, and each ordinate subrange is located in the range of default ordinate, you can judge the pen
Draw and be located in the range of predeterminable area.
In another specific embodiment, for complex stroke, default transverse and longitudinal can also be sat according to specific stroke
Mark scope is also divided into more than two default transverse and longitudinal coordinate subranges, and described two default transverse and longitudinal coordinate subranges above can
Partly overlap.If each abscissa subrange is located in corresponding default abscissa subrange, and each ordinate subrange
In corresponding default ordinate subrange, you can judge that the stroke is located in the range of predeterminable area.
With continued reference to Fig. 2, in the specific implementation of step S29, it is judged as that the stroke position is correct.
When the abscissa scope of the stroke is located in the range of default abscissa, and the stroke ordinate scope position
