A method performed by an augmented reality (AR) system includes receiving a command that is input by the user through the AR system. The augmented reality (AR) system includes a hardware processor and an AR display configured to present virtual content in an environment of a user. The command specifies a type of virtual object to be presented in the environment. In response to the command, virtual objects of the specified type are presented in the environment, and a presentation of at least one of the virtual objects is altered in response to detecting a movement of the user in proximity to the at least one virtual object.
