Abstract

An information system for supplying a predetermined region with information includes a transmitter for transmitting information in digitally coded form and a hand-held device. The hand-held device includes a receiver for receiving the information transmitted by the transmitter, a digital memory device for storing the received information, a reproduction device for reproducing the stored information, in particular acoustically and/or optically, and an event detection device for detecting specific events, wherein, upon detection of an event from the stored information, the information which is assigned to the detected event is selected for reproduction.
