1. A method for a user to control operation of a measurement device, the method comprising: providing a relationship between a command and a gesture, the gesture corresponding to a body position of the user; providing the measurement device, the measurement device measuring in operation three-dimensional coordinates of a point on a surface based at least in part on light from a first light projected from a first light source of the measurement device; projecting a second light beam from a second light source and acquiring an image of a user; generating, at a processor, a skeletal model of the user from the image; capturing, by a camera, the body position of the user corresponding to the gesture; identifying, at the processor, from the skeletal model the performing by the user of the gesture; determining, at the processor, the command based at least in part on the identifying of the gesture; and executing, at the processor, the command with the measurement device.
