1. A coordinate measuring device that measures a work piece comprising: a measuring probe configured to measure three-dimensional coordinates; a measuring arm configured to support the measuring probe, and further configured to output position information for calculating the three-dimensional coordinates; a controller connected to the measuring arm and configured to detect the three-dimensional coordinates based on the position information; and a memory configured to store a list of a predetermined gesture and a predetermined command associated with each other, wherein the controller is further configured to: determine whether the measuring probe is currently being used for measuring the work piece, detect a trajectory of movement of the measuring probe based on the continuously detected three-dimensional coordinates, when it is determined that the measuring probe is not currently being used for measuring the work piece, recognize a gesture corresponding to the trajectory detected based on the continuously detected three-dimensional coordinates, by cross-checking the detected trajectory with the predetermined gesture stored in the memory, when it is determined that the measuring probe is not currently being used for measuring the work piece, and reference the list stored in the memory to identify and execute a command associated with the recognized gesture in the list.
