Abstract: The present invention provides for a system and method of wirelessly triggering portable devices to provide a user with audio and/or visual information related to a show or attraction, for example, or for the purposes of captioning, language translation, assistive listening, and descriptive audio. As a person moves about a venue, a portable device receives signals from transmitters at venue locations. Transmissions may be via infrared or radio signals. The receiving device decodes each signal as a venue location, event time, or device trigger. The receiving device processes the signal and its memory to start a presentation on the device. The portable device memory contains audio, text, graphics, and/or visual content; device playback may contain one or many of these stored contents. The stored content may be synchronized with the user's location, time of travel, time of day, time of a show, or an event in a show. Stored content may be in one or many languages.
