When the property bar is triggered, after the cursor is moved to the icon, the pen point 2 is pressed downwards to trigger the first limit switch 33 once, the icon is selected, and the touch pad 11 is touched to open the property bar.

In the normal mode of the mouse, the point contact, the up-down sliding, the sequential triggering of the first limit switch 33 and the second limit switch 34, the primary triggering of the first limit switch 33, and the continuous triggering of the first limit switch 33 of the touch pad 11 are all connected in a corresponding communication manner through the existing protocol of the general mouse, so as to realize the corresponding function control. In the normal mode, the main control module shields the geomagnetic sensors in the pressure sensor 5 and the nine-axis sensor.

When the pen point 2 enters a writing mode, the main control module detects a path during writing and drawing according to a gyroscope and an acceleration sensor of a nine-axis sensor in the pen-shaped mouse, data calculation is fed back to the terminal equipment through the communication unit, the main control module shields signals of a geomagnetic sensor, a first limit switch 33 and a second limit switch 34 in the nine-axis sensor, pressure detected by the pressure sensor 5 is detected, and thickness of the pen point and the thickness of the pen touch are adjusted in real time through pressure applied on the pressure sensor 5 by a return spring 42 carried by the pen point 2 during writing and drawing and through set pressure conversion.

In the air mode, the main control module detects the angle of the pen-shaped mouse relative to the earth magnetic field through the geomagnetic sensor of the nine-axis sensor, so that the posture of the pen-shaped mouse in the air is determined, and the rotation of the three-dimensional software internal model can be controlled through real-time posture detection.

For example, when 3D drawing is performed in an EDA, it is necessary to perform origin correction before each operation, that is, to make the current position of the pen-shaped mouse coincide with the three-dimensional origin of coordinates of the EDA, and to define the mouse as a point in the three-dimensional drawing for calibrating the origin, a part to be operated can be directly specified in the 3D drawing by moving the pen-shaped mouse.

For example, if the model in the software is turned downwards, the pen is held by first bending upwards and then swinging downwards in a semicircular way. When the pen tilts upwards, the three-axis geomagnetic sensor and the gyroscope are always in a working state, namely the change of the space position of the pen is always monitored, then the forefinger point presses the touch pad 11 and does not place, the current position of the pen-shaped mouse is determined to be a selected point through a program, the pen-shaped mouse is swung in a downward semicircular mode, the triaxial geomagnetic sensor and the gyroscope are compared and calculated through position data to obtain the space position change track of the mouse and the pen when the origin point is calibrated, the space position change track is fed back to a software model in real time, the acceleration sensor reflects the speed of turning after calculating the acceleration, namely the turning speed of the model in the program, realizes that the motion of the model in the software can be consistent with the track of the pen and turned downwards together, and then the display angle and the visual angle of the three-dimensional graph can be changed rapidly along with the motion track of the hand, and various command operations for accurately controlling the display angle and the visual angle corresponding to the EDA by using the space action are achieved.
