  • Method and apparatus for determining interaction position
    Patent number: 11126228
    Abstract: A method and an apparatus for determining an interaction position. The method is applied to a projection interactive system. In the display direction of the projection plane, the light plane is formed above the projection plane via the predetermined light signal emitted by the light emitter, and the image pickup device can collect the predetermined light signal from the work region of the light plane. The predetermined light signal is monitored when the predetermined light signal collected by the image pickup device is obtained. As long as a person interacts with the projected image, the light plane for identifying the interaction position is inevitably penetrated, leading to the change of the predetermined light. The projection interactive system can recognize the signal change generated by the interacting action, and determine the interaction position of the interacting action according to the signal change.
