Zusammenfassung: | A self-adaptive positioning device for detection region and a product thereof are provided in the present invention. The self-adaptive positioning device for detection region includes a housing, a marking object and a detector. The shell includes an aperture. The marking object is disposed on a preset position behind the center point of the aperture in the shell. The detector has a detection region. The region forming by the marking object and the edge of the aperture is analog to the detection region. Therefore, when a user can see the marking object, it means that the user is in the detection region. |
