The chip manual records the TILT register and the XOUT, YOUT, and ZOUT registers. The data in the TILT register is one byte. bit [2] -bit [4] is the position direction information. The value of these three bits is 001 to indicate that the horizontal head is to the left, 010 to indicate the horizontal head to the right, 101 to indicate vertical upside down, and 110 to indicate normal vertical. The XOUT, YOUT, and ZOUT registers are one byte, and the data of the x, y, and z axes are stored in the XOUT, YOUT, and ZOUT registers.

It changes from horizontal to vertical, and then switches to the corresponding operating system according to the current position status. Here is just an example to illustrate that 45 degrees is the critical point for the change of position status. The present invention does not limit the specific critical point value. For example, the rotation angle α may also be 30 degrees, 60 degrees, etc., or the dual operating system electronic device 20 The initial position is transformed into a position parallel to the horizontal plane, or from the initial position to a preset position in the three-dimensional space, etc. The present invention does not limit the selection of the critical point value when the system is switched.

The data of the x, y, and z axes in the XOUT, YOUT, and ZOUT registers can always be read as the current position information. For example, the initial position of the dual operating system electronic device 20 is state 1 on the left in FIG. Right, when the dual operating system electronic device 20 is rotated 30 degrees, the data of the x, y, and z axes in the gravity sensor are read, and the current position status is determined to be horizontal or vertical based on the data of the x, y, and z axes. When using other sensors to detect the position information of the dual operating system electronic device 20, different designs may be made according to the chip specifications of the specific sensor.
