Apparatus and method for wirelessly triggering the simultaneous playing of multiple language tour commentaries in a group tour environment

摘要

A Master Controller Device with a GPS receiver triggers the playing of location specific audio commentaries stored on Personal Wireless Receiver Devices worn by participants of a group tour who are moving through a geographic area. The master controller device broadcasts an encoded instruction to the receiver devices, each of which stores a database of digital audio files pertaining to different tour options and language options. The receiver device selects an audio file for playback to the user based on the encoded instruction and a language pre-selected in the receiver device by the user.
