In some embodiments, the step 620 of the method for correcting the pen includes:
establishing a current pen holding posture model corresponding to the current pen holding posture based on the writing angle information, the touch pressure information and the touch position information;
comparing the current pen holding posture model with the target pen holding posture model;
and under the condition that the matching degree of the current pen holding posture model and the target pen holding posture model is smaller than a target threshold value, determining that the current pen holding posture is wrong, and outputting prompt information.
The touch pressure information and the touch position information acquired by the pressure sensor array and the touch sensor array are areas contacted by a hand and a correction pen when a user holds the pen, and can be roughly divided into a first web part, a thumb part, an index finger part and a middle finger part.

In this embodiment, the abstract mathematical data collected by the sensor is converted into a determined and realistic model showing the physical form of the hand, and then whether the current pen-holding posture model belongs to an accurate and healthy action is identified, that is, whether the current pen-holding posture model is matched with the target pen-holding posture model and whether the matching degree of the two models is smaller than a target threshold value is judged.
The target threshold is a preset matching degree threshold, when the matching degree of the current pen-holding posture model and the target pen-holding posture model is greater than or equal to the target threshold, the current pen-holding posture model is relatively similar to the target pen-holding posture model, and the current pen-holding posture can be classified into an accurate and healthy pen-holding posture; when the matching degree of the current pen holding posture model and the target pen holding posture model is smaller than the target threshold value, the difference between the current pen holding posture model and the target pen holding posture model is large, and the current pen holding posture belongs to an incorrect pen holding posture.
In actual implementation, the target threshold may be adjusted, and it is understood that the larger the target threshold is, the more strict the judgment on whether the current pen-holding posture model is the correct pen-holding posture is.

For example, whether the current pen-holding posture is too low (too close to the pen point) or too high, whether the cooperation between the finger tips is coordinated (such as the finger tips hold the pen body), whether the fingers are bent excessively is reflected by the distance between the finger tips and the web of a tiger, and whether the pen is too hard when being held, whether the finger tip part is too hard, and whether the pen body is too inclined are judged by pressure sensing at the web of the tiger.
And outputting prompt information to prompt a user to correct the pen holding posture when judging that the current pen holding posture has bad actions, namely determining that the current pen holding posture is wrong.
When the size of the hand of the user is modeled based on data such as the distance between the position of the fingertip and the position of the tiger's mouth and the relative position between the fingertips, which are represented by the touch pressure information and the touch position information, the left-right-left-falling-off condition of the user can be recognized at the same time.
