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. Presentation of stored content on the portable device may also be altered by user preference, stored logic constraints, automatic learning of user behavior, or user interaction with other devices.
