Abstract: Disclosed herein are a method for human-machine interaction and an apparatus for the same. The method includes receiving object identification input for identifying an object related to the task to be dictated to a machine through the I/O interface of a user device that displays a 3D space; displaying an object identification visual interface, corresponding to the object identified within the space recognized by the machine, on the user device in an augmented-reality manner; receiving position identification input for identifying a position in the 3D space related to the task; displaying a position identification visual interface, corresponding to the position identified within the space recognized by the machine, on the user device in an augmented-reality manner; and receiving information related to the result of the task performed through the machine.
