Abstract: The present invention relates to a stereo interactive method adapted for an interactive scene of a stereo display device and a stereo interactive operating stick. The method includes: obtaining motion trajectory information of the operating stick; calculating invasion degree information of an invasion that the operating stick applies to a virtual object displayed by the display device according to motion trajectory information and preset property information of the virtual object; calculating interaction feedback information according to motion trajectory information, invasion degree information and the preset property information; and controlling the operating stick and the virtual object to make responses matched with the preset property of the virtual object according to the interaction feedback information. The present further provides stereo interactive display device, operating stick and system.
