Abstract: A handwriting forming method, a handwriting forming apparatus, and an electronic device are provided. The method includes: determining a group of plurality of trajectory points and obtaining trajectory information of each of the plurality of trajectory points, the trajectory information including a pressure value; establishing a plurality of trajectory units corresponding to the plurality of trajectory points in one-to-one correspondence based on the trajectory information; and connecting the plurality of trajectory units to form a handwriting for displaying. A size of each trajectory unit is determined based on a pressure sensing amount corresponding to the trajectory unit, and the pressure sensing amount is obtained based on the pressure value of a corresponding trajectory point. In the case where the pressure value is less than a first threshold, the pressure sensing amount is a first constant regardless of whether the pressure value of the corresponding trajectory point changes.
