The invention relates to an electro-optical distance measuring device for measuring distances in a contactless manner, comprising at least one laser distance-measuring module, which has a laser source for emitting an optical measuring light beam in the direction of an object and which has a receiver for detecting reflected portions of the optical measuring light beam, and comprising an analyzing and control unit for determining a distance on the basis of the received portions of the optical measuring light beam. According to the invention, criteria are defined and stored which characterize a determined gesture for triggering the distance measurement, said gesture being carried out by a user using a test body that crosses the measuring light beam in an encoded manner. Additionally, the analyzing and control unit is designed to carry out a measurement-triggering gesture mode in which reflected portions of the optical measuring light beam are continuously detected automatically and the continuously detected reflected portions are analyzed with respect to characteristic variables, said variables being dependent on a gesture that crosses the measuring light beam by means of a test body in an encoded manner. The characteristic variables are used to test whether said variables correspond to the defined criteria so that the gesture that is carried out by the user is identified as the gesture for triggering the distance measurement if the characteristic variables correspond to the criteria. Finally, a measurement of the distance to the object can be automatically triggered in response to an identification of the gesture for triggering the distance measurement. |
