Abstract
A method of conveying information to a user of a coordinate measurement device, includes providing a first target projector, sending a first light beam from the device to a retroreflector; receiving a second light beam from the retroreflector; measuring the orientational and translational sets, the translational set based on the second light beam; selecting first information to be conveyed from the group consisting of one or more positions on the object, a direction indicated by a moving pattern, a message that includes one or more symbols or alphanumeric characters, a hidden feature, a measured object characteristic, a modeled characteristic, a magnified representation of surface characteristics, a pattern having meaning according to a rule, and combinations thereof; determining a first light pattern corresponding to the information; storing the first light pattern; and projecting the first light pattern onto the object based on the translational and orientational sets.
