Claim:
1. Method for optically scanning and measuring an environment, the method comprising: providing a three-dimensional (3D) measurement device having a first camera, a second camera and a projector, the 3D measurement device further having a control and evaluation device operably coupled to the at least one camera and the projector, the control and evaluation device having memory; providing a correspondence between each of a plurality of control functions for the 3D measurement device and each of a plurality of gestures, each gesture being a movement of the 3D measurement device, at least one first gesture from among the plurality of gestures being defined as a movement along a path by the 3D measurement device, the first gesture corresponding to a first control function of the 3D measurement device, the correspondence between each of the plurality of control functions and each of the plurality of gestures being stored in the memory; emitting a light pattern onto an object with the projector; recording a first set of images of the light pattern with the first camera and the second camera at a first time; recording a second set of images of the light pattern with the first camera and the second camera at a second time; producing a 3D scan of the object based at least in part on the first image and the second image; moving the 3D measuring device along a second path from a first position to a second position; determining the first gesture based at least in part on the movement from the first position to the second position; and executing the first control function on the 3D measurement device based at least in part on the determination of the first gesture.
