Claim 3:
4. The writing interaction method according to claim 1, further comprising:
detecting a fourth touch event of a smart pen and acquiring a corresponding identifier of the smart pen;
determining whether the fourth touch event is generated by a newly added smart pen according to the identifier of the smart pen;
under a condition that the fourth touch event is not generated by the newly added smart pen, determining whether the fourth touch event is generated in the generated writing regions according to a location where the fourth touch event is generated;
under a condition that the fourth touch event is not generated in the generated writing regions, tentatively expanding the writing region corresponding to the smart pen according to a preset rule, so as to cover a track corresponding to the fourth touch event;
determining whether the tentatively expanded writing region overlaps with other writing regions;
under a condition that the tentatively expanded writing region overlaps with the other writing regions, canceling expansion of the writing region corresponding to the smart pen and generating no handwriting according to the fourth touch event;
under a condition that the tentatively expanded writing region is not overlapped with the other writing regions, expanding the writing region corresponding to the smart pen and generating handwriting according to the fourth touch event.
