Abstract: Provided are a method and apparatus for interaction in a three-dimensional space. The method includes: displaying a target augmented reality three-dimensional picture on a target augmented reality device, and displaying a target virtual interaction object in a virtual three-dimensional space in the target augmented reality three-dimensional picture, wherein the real three-dimensional space is rasterized and the virtual three-dimensional space is rasterized, and there is a mapping relationship therebetween; acquiring a target movement trajectory of a target object in the real three-dimensional space; determining a real cell set through which the target movement trajectory passes; determining a passing first virtual cell set corresponding to the passing real cell set; and determining whether the target movement trajectory triggers a target interaction operation of the target virtual interaction object according to the position relationship between the first virtual cell set and a second virtual cell set.
