Below with reference to Fig. 3, Fig. 4 and Fig. 5, method of collecting handwriting information and the method that the positive guide user practises handwriting are described.
With reference to figure 3 a kind of method of collecting handwriting information has been described.
After the operation beginning, 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.When the touch that detects the user, the positional information that touch-screen 2 sensing user touch also is converted into position signalling.Preferably, but this touch-screen also the pressure that touches of sensing user size and be converted into pressure signal.
Then, touch-screen 2 sends to its sensed signal embedded to system 5.Embedded system 5 receives the signal that touch-screen 2 senses, and signal is handled to obtain the relevant information of writing.Such as, by can obtain the handwriting information of user writing to the position Signal Processing.Preferably, by to 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 the touch-screen 2, thus the literal of importing with the pattern explicit user of " What You See Is What You Get ".For example, handwriting information can be shown as the stroke of corresponding literal, 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 beginning, the user can select this handwriting information at concrete literal, thereby this literal 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, the user can repeat said process, thereby repeatedly information gathered in same literal, and at this repeatedly information handle to obtain best person's handwriting and vigour of style in literary composition data.For example, can adopt the processing on the statistics and obtain optimum data this numerical information, perhaps selecting certain data by the 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 a plurality of mould training board for handwriting system.
With reference to figure 4, Fig. 4 has described the method that a kind of positive guide user practises handwriting.
When beginning operation, the user selects to want the literal practised.For example, the touch-screen by the mould training board for handwriting system 2 selects to want the literal practised.Embedded system 5 reads expert's handwriting information and vigour of style in literary composition information (if any) and it is illustrated on the touch-screen 2 from the database that is stored in 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 present existing handwriting data storehouse that on PC, produce utilized.Preferably, can the ways of writing of this literal be presented on the touch-screen 2 with the form of navigation animation.
When the 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 also will be handled to be presented on the touch-screen 2 as person's handwriting (and vigour of style in literary composition) information, as above-mentioned from touch-screen 2 received signals.Preferably, embedded system 5 is saved in the database in the storer 8 this person's handwriting (and vigour of style in literary composition) information for analysis.Simultaneously, 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, the user is carried out guiding in real time.In one embodiment, embedded system 5 is by brightness of luminous point on the control touch-screen and writing of pattern guiding user.Such as, can make the point brilliance on the direction that next user should wield the pen increase the direction of wieling the pen that (perhaps flicker) guides the user.In addition, the thickness of the stroke that can also form by the luminous point on the direction of wieling the pen is represented the due dynamics of wieling the pen of user.Preferably, next the user can be play the stroke of wieling the pen as animation.By positive guide, increased the enjoyment the when user practises, and can increase the accuracy when practising the user.
Alternatively or additionally, can also adopt the mode of auditory tone cues to user's guiding.Instruct such as, the action that loudspeaker 10 will be done 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.).
Fig. 5 has described the analytical approach to the process of practising handwriting: after all strokes were finished, expert data or historical data that embedded system 5 can be practised this user to preserve in data and the system were analyzed, thereby provided reference or suggestion to the user.Such as similarity analysis that provides writing words etc.
As mentioned above, mould training board for handwriting provided by the invention and the method for collecting handwriting information and guiding the user to practise handwriting have increased the enjoyment the when user practises handwriting, and have improved the effect of practising handwriting.
