1. A laser tracker comprising:
- a structure rotatable about a first axis and a second axis;
a first light source is coupled to the structure, the first light source being configured to launch a first light beam from the structure;
a distance meter is operably coupled to the first light source;
a first angular encoder is operably coupled to the structure to measure a first angle of rotation about the first axis;
a second angular encoder is operably coupled to the structure to measure a second angle of rotation about the second axis;
a projector is operably coupled to the structure that projects a two-dimensional pattern of light, the projector being configured to project the two-dimensional pattern of light simultaneously with the first beam of light;
a first camera operably coupled to the structure;
a processor and computer readable media operably coupled to the structure, wherein the processor is responsive to executable computer instructions to determine three-dimensional coordinates of an object illuminated by the two-dimensional pattern of light and to determine a distance to a target based at least in part on a measurement by the distance meter.

Abstract
A method and system are provided for controlling a laser tracker remotely from the laser tracker through gestures performed by a user. The method includes providing a rule of correspondence between each of a plurality of commands and each of a plurality of user gestures. A gesture is performed by the user with the user'"'"'s body that corresponds to one of the plurality of user gestures. The gesture performed by the user is detected. The gesture recognition engine determines a first command from one of the plurality of commands that correspond with the detected gesture. Then the first command is executed with the laser tracker.
