and S101, acquiring sensor data information of a wrist and each finger force point during writing.
Specifically, the force exerting parts and muscle changing parts of the wrist and the finger during standard pen holding and Chinese character writing are respectively determined. The hand-wearing device is respectively provided with a pressure sensor at the force-exerting part and a flexible stretching detection device at the muscle change part.
The bionic manipulator uses the motion principle of human hands (left and right hands) as a basic theory, uses ergonomics, physical mechanics, mathematical geometry and traditional Chinese medicine orthopaedics as bottom logic, analyzes and applies the data signals to the bionic manipulator, simulates hand motion, can receive data signals of all parts of the hands, analyzes the data signals, stores, analyzes, images and feeds back the data signals, and can control and assist the hand motion. The movement of the pen is used for positioning, collecting, recording, analyzing, assisting and pre-judging, the hand movement is simulated to finish the writing process, and the pen holding posture action and the force point are corrected. The design not only can be used for writing Chinese characters by the right hand, but also has exclusive targeted design and data for congenital hand defects, left-handed writing and English writing.
The human engineering has a limit on the opening size of the tiger's mouth at the thumb, and the traditional Chinese medicine orthopaedics can know that the opening size of the tiger's mouth is controlled by the abductor of the major fish but not by the flexor. If the hand data is short of the tiger mouth, the data can be optimized. The lumbrical muscles of the four fingers at the palm do not exert force. The human engineering and physical mechanics are combined to integrally need the gravity center, and the force application point of the gravity center is on the first joint of the little mother finger and is not on the pisiform bone and the hypothenar of the wrist. The three fingers form an included angle of 120 degrees on the pen to ensure that the pen is stressed uniformly. The three fingers ensure stable running route on the same plane. The fingertips of three fingers, the midline of the tiger's mouth, the wrist and the arm of the whole arm form a straight line.
The middle finger is used as a direction axis, and the first joint of the middle finger is usually in a relaxed state and is used as a supporting point through the bone hardness and the human body structural force to control the direction of the vertical and horizontal movement. Medium finger variants produce resilience with ergonomic features that can accomplish directions of motion such as horizontal hooks, vertical hooks, and skimming. The thumb is used as a power shaft for exerting force on the fingertip, and a physical and mechanical object exerts force on the power shaft in a static state, and the power shaft moves along the direction of the force. For example, if the thumb is forced to one side, the middle index finger will be zero-resistance to complete the lateral movement. The forefinger is used as a gravity axis to exert force on the fingertip and is mainly responsible for controlling the pressure of a pen point, the forefinger is secondarily matched with the thumb to be driven in multiple directions, the first joint of the forefinger cannot be turned outwards, and the elastic force generated by deformation of the forefinger can damage the plane balance of the fingertip. Such as vertical, operating through geometric triangles: the 1/2 positions of the second joint and the second joint of the index finger and the third joint of the index finger form a triangle with three finger tips, the side lengths of the thumb and the index finger are unchanged, the connecting line of the 1/2 positions of the second joint and the second joint of the index finger is widened as the bottom edge, the distance from the three finger tips to the tiger mouth is reduced, and the reduction process is the vertical movement direction. Holding the pen with the left hand: the left hand and the right hand are symmetrical, but the functions of the middle finger, the index finger and the thumb need to be alternated, exchanged and adjusted, but the basic operation structure and logic of the hands are unchanged.
Specifically, pressure sensors are arranged at the following three positions, the position alignment error is monitored, and the motion path is calculated. The tip of the index finger, near the nail. The tip of the thumb, close to the nail. The left side 1/2 of the first phalanx of the middle finger is close to the root of the nail (the left half of the left side of the first phalanx of the left hand, close to the root of the nail).
Pressure sensors are arranged at the following four positions to monitor stable pressure and weak pressure to ensure the stability of the hand platform. The root parts of the index finger and the middle finger are adjacent; the right side of the first joint of the little mother finger (left hand: left side of the first joint of the little mother finger); the right side of the palm at the little abductor muscles; the triangular bone at the root of the wrist.

And monitoring the deformation condition and the strength of the outer side of the joint. Lateral side of first joint of the thumb, lateral side of second joint of the thumb, and lateral side of root of metacarpal bone of the thumb. The lateral side of the first joint of the index finger, the lateral side of the second joint of the index finger and the lateral side of the third joint of the index finger. Lateral to the first joint of the middle finger, lateral to the second joint of the middle finger, and lateral to the third joint of the middle finger. Lateral to the first joint, lateral to the second joint, and lateral to the third joint. The lateral side of the first joint of the little finger, the lateral side of the second joint of the little finger and the lateral side of the third joint of the little finger.
Pressure sensors are arranged at the positions of the abductor hallucis brevis and the flexor hallucis brevis to monitor the force state and the force magnitude of the abductor hallucis muscles and the flexor hallucis muscles. Pressure sensors are arranged at four positions of dorsal muscles and extensor digitorum bones, and finger extension states and force are monitored.
And S102, recording the writing track of each Chinese character through writing recording equipment.

3. The method for correcting the pen-holding posture of claim 1, wherein the recording of the writing trace of each Chinese character by the writing recording device comprises:
determining an initial coordinate point when the Chinese character is written in the rectangular coordinate system of the power grid plane;
when writing Chinese characters, the size proportion of the written Chinese characters is calculated, and the size of the power square is adjusted to place the Chinese characters in the middle of the coordinate system.
4. The method for correcting a pen-holding posture according to claim 3, wherein the adjusting the size of the power square to place the Chinese character at a middle position of a coordinate system comprises:
when a straight line stroke is input and a straight line falling point is determined, calculating a central coordinate value of a current writing part according to the initial coordinate point;
determining the adjustment size of the power grid according to the central coordinate value;
or,
if the stroke has curve input, recording a full coordinate point;
determining the coordinates of the circle center according to the size proportion of the full coordinate point and the curve;
and determining the adjusted size of the power grid according to the coordinate of the circle center.
5. A wearable device, characterized in that the method for correcting pen-holding posture based on claim 1 comprises:
a flexible glove;
the flexible stretching detection device and the pressure sensor are arranged in the flexible glove;
the microprocessor is electrically connected with the flexible stretching detection device and the pressure sensor respectively;
a memory for storing executable instructions of the microprocessor;
and when the microprocessor reads the executable instruction in the memory, the data acquired by the flexible stretching detection device and the pressure sensor are processed to determine the wrist direction, the pen holding posture and the hand strength information.
