Claim Text:
1. A method for communicating, from a user to a laser tracker with steps comprising: providing the laser tracker having a structure rotatable about a first axis and a second axis, a first light source that launches a first light beam from the structure, a distance meter, a first angular encoder that measures a first angle of rotation about the first axis, a second angular encoder that measures a second angle of rotation about the second axis, and a processor; providing a projector and a first camera; providing a rule of correspondence between each of a plurality of commands and each of a plurality of gestures, each gesture from among the plurality of gestures including a spatial configuration of a first body part of the user relative to a second body part of the user, the rule of correspondence based at least in part on the spatial configuration; performing by the user a first gesture from among the plurality of gestures, the first gesture corresponding to a first command; projecting from the projector a second light onto the first body part and second body part, the second light being a two-dimensional pattern of light; reflecting the second light from the first body part and second body part as a third light; capturing a portion of the third light with the first camera to obtain a digital representation of the portion of the third light; determining the first command based at least in part on processing the digital representation according to the rule of correspondence; executing the first command with the laser tracker; and measuring three dimensional coordinates of a retroreflector based at least in part on measurements of the distance meter, the first angular encoder, the second angular encoder and a speed of light.
