With the above embodiment, the amount of calculation of data can be further reduced by setting the threshold.
According to a specific implementation manner of the embodiment of the present disclosure, the packaging the time sequence, the pressure value sequence, the position coordinate sequence, and the acceleration value sequence corresponding to the handwriting data segment includes:
And taking the time sequence, the pressure value sequence, the position coordinate sequence and the acceleration value sequence as row vectors of a matrix, and forming a handwriting matrix corresponding to the handwriting data segment in a time sequence.
