Virtual object manipulation within physical environment

A method, computing device and head-mounted display device for manipulating a virtual object displayed via a display device are disclosed. In one example, image data of a physical environment comprising physical features is received. A three dimensional model of at least a portion of the environment is generated. Candidate anchor features that each correspond to one of the physical features are extracted from the image data. User input is received that manipulates the virtual object as displayed within the environment. Based on the manipulation, a correspondence between a virtual anchor feature of the virtual object and a correspond ing candidate anchor feature is identified. An indication of the corresponding candidate anchor feature at its corre sponding physical feature within the environment is dis played to the user.
