Abstract
A method for optically communicating, from a user to a laser tracker, a command to control operation of the tracker includes providing a rule of correspondence between a plurality of commands and a plurality of positions, each position being a 3-D coordinate; selecting by the user a first command from among the commands and moving by the user a retroreflector to a first position wherein the first position corresponds to the first command. Also, projecting a first light from the tracker to the retroreflector, reflecting a second light from the retroreflector, the second light being a portion of the first light and obtaining first sensed data by sensing a third light, the third light being a portion of the second light. Further, determining the first command based on processing the first sensed data according to the rule of correspondence and executing the first command with the tracker.
