the sliding direction obtaining unit is used for obtaining the sliding direction of the writing pen at the specified time according to the sliding track;
the stroke direction obtaining unit is used for obtaining the stroke direction corresponding to the target stroke according to the target stroke;
and the deviation angle calculation unit is used for calculating and obtaining a deviation angle between the sliding direction and the stroke direction.
9. The apparatus of claim 6, wherein the friction adjustment module comprises:
the current indication information generating unit is used for generating current adjustment indication information corresponding to the writing pen according to the deviation angle;
and the current indication information sending unit is used for sending the current adjustment indication information to the writing pen so that the writing pen controls the current adjustment between the writing end of the writing pen and the screen according to the current adjustment indication information.
10. The apparatus of claim 6, further comprising:
the touch pressure acquisition module is used for acquiring a touch position of the writing pen on the screen, which corresponds to the target character, and the touch pressure of the writing pen;
the target pressure determining module is used for determining target touch pressure according to the touch position;
and the force indicating information generating module is used for generating writing force indicating information under the condition that the pressure difference value between the touch pressure and the target touch pressure is out of a pressure threshold range.
11. An electronic device comprising a processor, a memory, and a program or instructions stored on the memory and executable on the processor, the program or instructions when executed by the processor implementing the steps of the method of controlling friction adjustment according to any one of claims 1-5.
