ABSTRACT:
An information retrieval system includes a base station and multiple display stations. A user gives a voice command to one of the display stations and information is retrieved from the base station and displayed in real time; the information may be presented to the user both visually and aurally. The source of the information may be data stored at the base station, or data relayed by the base station from network sources such as the Internet, or from radio or television broadcast stations. The display station has a pull-down screen that can operate like a shade; it retracts using the energy in a wound-up spring.
