Computerized systems, methods, apparatuses, and computer-readable storage media are provided for generating a 3D map of an environment and/or for utilizing the 3D map to enable a user to control smart devices in the environment and/or to interact with a person in the environment. To generate the 3D map, perform the control, and/or interact with the person, a plurality of neuromuscular sensors may be worn by the user. The sensors may be arranged on a carrier worn by the user and may be configured to sense neuromuscular signals from the user. A camera configured to capture information about the environment may be arranged on the carrier worn by the user. The sensors and the camera provide data to a computer processor coupled to a memory.
