Below with reference to Fig. 3, Fig. 4 and Fig. 5, the method for handwriting information and the method that positive guide user practises handwriting of collecting described.
With reference to figure 3, a kind of method of collecting handwriting information is described.
After operation starts, this touch-screen is waited for user's touch (by lettering pen or other instrument, such as finger etc.), that is, wait for and write operation.In the time of the touch that user detected, the positional information that touch-screen 2 sensing user touch is also converted into position signalling.The size of the pressure that preferably, this touch-screen also can sensing user touches is also converted into pressure signal.
Then, touch-screen 2 sends to the signal of its sensing embedded to system 5.Embedded system 5 receives the signal that touch-screen 2 senses, and signal is processed to obtain the relevant information of writing.Such as, by can obtain the handwriting information of user writing to the processing of position signalling.Preferably, by pressure signal processing can obtain the vigour of style in literary composition information of user writing.Preferably, embedded system 5 is presented at this handwriting information and vigour of style in literary composition information on touch-screen 2, thereby shows with the pattern of " What You See Is What You Get " word that user inputs.For example, handwriting information can be shown as the stroke of corresponding word, and vigour of style in literary composition information can be shown as the thickness of this stroke.
Then, this handwriting information and vigour of style in literary composition information (if any) are saved in the storer of embedded system 5.Before or after this operation starts, user can select this handwriting information for concrete word, thereby this word and its corresponding person's handwriting and vigour of style in literary composition information are saved in the database of this storer 8 simultaneously.
In another embodiment, user can repeat said process, thereby same word is gathered to repeatedly information, and for this repeatedly information process to obtain best person's handwriting and vigour of style in literary composition data.For example, can adopt processing statistically and obtain optimum data this numerical information, or to select certain data by user be optimum data.Preferably, this person's handwriting and vigour of style in literary composition information can be by expert's typings.Preferably, this person's handwriting and vigour of style in literary composition information can be shared between multiple mould training board for handwriting systems.
With reference to figure 4, Fig. 4 has described a kind of method that positive guide user practises handwriting.
When operation starts, user selects to want the word of exercise.For example, select to want the word of exercise by the touch-screen 2 of mould training board for handwriting system.Embedded system 5 reads expert's handwriting information and vigour of style in literary composition information (if any) and is illustrated on touch-screen 2 from be stored in the database of storer 8.This expert's handwriting information can be by method above-mentioned by user's typing.Also can deposit in by alternate manner, such as, the handwriting data or the current existing handwriting data storehouse that on PC, produce utilized.Preferably, can the ways of writing of this word be presented on touch-screen 2 with the form of navigation animation.
When user writes on touch-screen, the touch of touch-screen 2 sensing user, and be converted into electric signal (for example person's handwriting signal) and send it to embedded system 5.Embedded system 5 receives signal and will process to be presented at touch-screen 2 as person's handwriting (and vigour of style in literary composition) information, as above-mentioned from touch-screen 2.Preferably, embedded system 5 is saved in the database in storer 8 this person's handwriting (and vigour of style in literary composition) information for analysis.Meanwhile, according to current person's handwriting (and vigour of style in literary composition) information and expert's person's handwriting (and vigour of style in literary composition) information, user is carried out to guiding in real time.In one embodiment, embedded system 5 is by controlling the brightness of the luminous point on touch-screen and writing of pattern guiding user.Such as, can make point brilliance in direction that next user should wield the pen increase (or flicker) to guide user's the direction of wieling the pen.In addition, can also represent the due dynamics of wieling the pen of user by the thickness of the stroke of the luminous point composition in direction of wieling the pen.Preferably, next user can be play the stroke of wieling the pen as animation.By the positive guide to user, increase enjoyment when user practises, and can increase the accuracy while exercise.
Alternatively or additionally, can also adopt the mode of auditory tone cues to user's guiding.Such as, action that loudspeaker 10 will do user's next one under the control of embedded system 5 (such as rising and falling of the direction of wieling the pen, pen etc.) is instructed.
Fig. 5 has described the analytical approach to the process of practising handwriting: after all strokes complete, expert data or historical data that embedded system 5 can be practised this user to preserve in data and system are analyzed, thereby provides with reference to or advise to user.Such as providing similarity analysis of writing words etc.
As mentioned above, mould training board for handwriting provided by the invention and the method for collecting handwriting information and guiding user to practise handwriting, increased enjoyment when user practises handwriting, and improved the effect of practising handwriting.
