B. camera (20) is gathered image and is extracted face feature, after computing machine (22) is handled feature, whether judge head part's attitude changes up or down, make that by governor motion controller (23) sending controling instruction driving dual-axle motor (3) rotates, the rotating drive synchronous pulley first (4) of dual-axle motor (3), synchronous pulley (4) rotates and drives synchronous pulley second (5), the rotation of synchronous pulley second (5) drives swivel arm (6) and does pitch regulation up and down, thereby realizes that display is to the tracking adjusting up or down of user's head pose;
C. camera (20) is gathered image and is extracted face feature, after computing machine (22) is handled feature, whether judge the head part position changes forward or backward, make motor first (7) rotate by governor motion controller (23) sending controling instruction, the rotating drive telescopic arm (14) of motor first (7) is mobile certain displacement backward, can realize that display is to the adjusting of the tracking before and after user's head position.
5. a site type display interfaces adaptive tracing control method adopts site type display adaptive tracing regulating device according to claim 1 to operate, and it is characterized in that operation steps is as follows:
Microphone collector (21) collects audio-frequency information, computing machine (22) is according to the voice messaging that collects, using shotgun microphone to carry out velocity of wave follows the trail of, regularly judge the voice direction of surveying the speaker, when finding that the relative location of displays of user changes to the left or to the right, judgement information is sent to governor motion controller (23), controller (23) sending controling instruction makes and drives the on the spot interior rotation platform motor rotation of universal stage (1), the rotating drive rotation platform (2) of this motor turns over certain angle to the left or to the right, thereby realization is regulated the tracking that the user moves to the left or to the right;
Perhaps, when user's certain position before display, the user sounds, microphone collector (21) collects audio-frequency information, computing machine (22) is according to the voice messaging that collects, using shotgun microphone to carry out velocity of wave follows the trail of, regularly judge the voice direction of surveying the speaker, when finding that the relative location of displays of user upwards changes, judgement information is sent to governor motion controller (23), controller (23) sending controling instruction makes that driving dual-axle motor (3) rotates, the rotating drive swivel arm (6) of this motor (3) upwards turns over certain angle, thereby realization is regulated the tracking that user's head moves up, and can realize the tracking adjusting that user's head is moved down according to same principle;
Perhaps when user's certain position before display, the user sounds, microphone collector (21) collects audio-frequency information, computing machine (22) is according to the voice messaging that collects, using shotgun microphone to carry out velocity of wave follows the trail of, regularly judge the voice direction of surveying the speaker, when finding that the relative location of displays of user changes forward, judgement information is sent to governor motion controller (23), controller (23) sending controling instruction makes drive motor first (7) rotate, the rotating drive telescopic arm (14) of motor second (7) is mobile backward, thereby realization is regulated the tracking that the user moves forward; According to same principle can realize to the user backward mobile tracking regulate.
