In this embodiment, a relationship between a specific preset physical action and a position switch of the user for operating the Android device needs to be set first, and a common preset physical action may be left-right rotation or up-down inclination, where the up-down inclination is a certain angle of downward swing of the top of the mobile phone, and the down-down inclination is a certain angle of downward swing of the top of the mobile phone. Then, the specific position switching operations are bound, for example, a preset physical action of rotating leftward (clockwise rotation) may be defined as an operation of vertically roaming upward, and a preset physical action of rotating rightward (counterclockwise rotation) may be defined as an operation of vertically roaming downward, so that a selection of various operation combinations may be provided, so that the user may switch according to habits.
And S200, calling an API of the Android equipment to create a gyroscope object, and monitoring real-time physical actions of the Android equipment.
In this embodiment, when the user roams in the model of the Android device, the user needs to roam the model in the vertical direction, and may wake up a corresponding operation by rotating the mobile phone. The method includes the steps that an Android device gyroscope detects occurrence of a rotation event, after a response event is detected, an Android device API is called to create a gyroscope object, in the embodiment, the gyroscope object is a gyroscope SENSOR, a monitor is created according to the gyroscope SENSOR, direction data of the gyroscope is calculated through detection of the monitor, and when the SENSOR is registered and monitored, a SENSOR sampling DELAY constant SENSOR _ DELAY _ NORMAL is used for ensuring sampling frequency of the gyroscope object, so that accuracy of direction data acquisition is improved.
The direction data is spatial position information of the gyroscope, specifically angular velocities of the Android device along an X axis, a Y axis and a Z axis. The three values are raw data of the gyro sensor, and in the case of counterclockwise rotation along any axis, the value associated with the axis is a positive value. In the case of clockwise rotation, negative; and judging the preset physical action to which the real-time physical action belongs according to whether the rotation along a certain axis belongs to a positive value or a negative value.
And step S300, forming a mapping relation between the real-time physical action and the preset physical action to trigger corresponding position switching operation, so that the movement in the vertical direction is realized when the three-dimensional model roams.

The scheme of the invention is based on the law of conservation of angular momentum, and the rotation rate is measured along a certain coordinate axis. In use, the rotor of the gyroscope always points to a fixed direction when rotating, and the gyroscope can sense when the moving direction of the moving object deviates from a preset direction. The working principle of the mobile phone gyroscope is that a silicon gyroscope in a mobile phone can enable a mechanical structure in the mobile phone to be driven by electrostatic force, and if the mobile phone gyroscope rotates, displacement is generated in the orthogonal direction due to Coriolis force, and then capacitance change is generated. The displacement is in direct proportion to the rotation angular speed, and the change of the capacitance of the detector is converted into a Digital Signal Processing, and then the Digital Signal Processing can be delivered to an application processor for Processing.
