starting a power supply of the scanning pen, initializing the scanning pen, controlling a user direction identification module and a user distance measurement module to start running by the control module, respectively identifying the direction of a user relative to the scanning pen, measuring the distance between the user and the scanning pen, and transmitting the distance back to the control module;
when the scanning pen needs to make a sound, the control module calculates the decibel size that the sound sent by the active directional loudspeaker should have according to the received azimuth data and the distance data, the preset minimum decibel size that the user can hear when the sound reaches the user and the preset distance decibel relation calculation formula, and then controls the active directional loudspeaker to send the sound of corresponding decibel size to the azimuth where the user is located.
Further, in the method, when the orientation of the user is identified, the control module prompts the user to move the hand holding the wand in the set direction, the six-axis sensor senses the movement direction data of the wand and transmits the movement direction data to the control module, and the control module calculates the orientation of the user relative to the wand according to the movement direction of the hand of the user relative to the user and the actual movement direction of the wand.
The invention has the beneficial effects that: according to the invention, through the measurement of the azimuth and the distance of the user and the combination of the active directional loudspeaker, the direction and decibel of the sound emitted by the scanning pen are controlled, so that the sound of the scanning pen can be prevented from being heard by other people, and the privacy protection effect of the scanning pen is achieved.
