Abstract
The present disclosure provides a 3D interaction method. The 3D display device detects a distance between an operating element and a display screen and checks whether the distance is less than a maximum distance of a 3D image pointed by the operating element protruding out of the display screen. When the distance is less than the maximum protruding distance of the 3D image pointed by the operating element, the 3D display device acquires a viewing distance between a viewer and the display screen. Based on the acquired viewing distance and the distance between the operating element and the display screen, the 3D display device adjusts the parallax of the 3D image pointed by the operating element to cause an actual distance of the 3D image pointed by the operating element protruding out of the display screen equal to the distance between the operating element and the display screen.
