Abstract
A device for guiding a person along a traveled path enables the wearer of the device to be guided back along the traveled path in an electronically supported manner even under conditions under which orientation is difficult. The device has a portable ejection means (), in which a container () for accommodating a plurality of transponders () and an ejection mechanism (), which is actuated by a control device () to eject a transponder () from the container (), are present. A control unit () is prepared such as to actuate the ejection mechanism () at predetermined time intervals or at predetermined distances in space. A portable transmitter/receiver device () is designed to detect at least one of the transponders () dropped off and to generate a signal representative of the direction in which that transponder () is located. A portable display device () receives the direction signal of the transmitter/receiver means () and offers the wearer a visual and/or acoustic display of the direction.
