Multidirectional multisound information system
View Patent ↗Exemplary embodiments provide an information system adapted to focus a plurality of audio messages to a plurality of different locations. As a consumer passes a display, their attention is attracted based on the series of messages. Further, a consumer can obtain more and different information as they change their position. Exemplary embodiments may also display a different image to the consumer depending on the position of the consumer relative to the display. Further embodiments may utilize touch-screen technology to allow a user to select an icon from the screen and obtain further information either through additional messages, video, or both.
1. A multi-sound multi image information system for use with a liquid crystal display (LCD) having a plurality of pixels arranged in vertical rows, where every third vertical row comprises a grouping of pixels so that the entire LCD is divided into three vertical groupings of pixels; a semi-transparent plate in front of the LCD; a plurality of vertical lines placed on the plate which permit the first grouping of pixels to be viewed only from a first viewing position, permit the second grouping of pixels to be viewed only from a second viewing position, and permit the third grouping of pixels to be viewed only from a third viewing position; the system comprising:
a first sound focusing device adapted to transmit a first message to the first viewing position;
a second sound focusing device adapted to transmit a second message to the second viewing position; and
a third sound focusing device adapted to transmit a third message to the third viewing position.
2. The system of claim 1 wherein:
said sound focusing devices comprises an array of loudspeakers.
3. The system of claim 1 wherein:
said sound focusing devices comprise parametric audio amplifier systems.
4. The system of claim 1 wherein:
said sound focusing devices transmit said messages using a carrier signal with a frequency above 20 k Hz.
5. The system of claim 1 further comprising:
a positional sensor operatively connected to each sound focusing device and adapted to sense the presence of a consumer within one of said viewing positions.
6. A multi-sound multi-image information system for use with a liquid crystal display (LCD) having a plurality of pixels divided into first and second pixel groups and a transparent substrate placed in front of the LCD and containing a plurality of vertical lines which block the second pixel group but allow transmission of the first pixel group when viewed from a first position and block the first pixel group but allow transmission of the second pixel group when viewed from a second position, the system comprising:
a first sound focusing device placed adjacent to the LCD which transmits a first message to the first position; and
a second sound focusing device placed adjacent to the LCD which transmits a second message to the second position, where the second position is at least two feet from the first position.
7. The system of claim 6 wherein:
said sound focusing devices comprises an array of loudspeakers.
8. The system of claim 6 wherein:
said sound focusing devices comprise parametric audio amplifier systems.
9. The system of claim 6 wherein:
said sound focusing devices transmit said messages using a carrier signal with a frequency above 20 k Hz.
10. The system of claim 6 further comprising:
a first positional sensor operatively connected to the first sound focusing device and adapted to sense the presence of a consumer within the first position; and
a second positional sensor operatively connected to the second sound focusing device and adapted to sense the presence of a consumer within the second position.
11. An advertising method for use with a liquid crystal display (LCD) having a plurality of pixels arranged in vertical rows, where every third vertical row comprises a grouping of pixels so that the entire LCD is divided into three vertical groupings of pixels, a transparent substrate placed in front of the LCD and having a plurality of vertical lines which cause the first grouping of pixels to be viewed only from a first viewing position, the second grouping of pixels to be viewed only from a second viewing position, and the third grouping of pixels to be viewed only from a third viewing position, the method comprising the steps of:
transmitting a first focused message to the first viewing position;
transmitting a second focused message to the second viewing position; and
transmitting a third focused message to the third viewing position.
12. The advertising method of claim 11 further comprising:
sensing the presence of a consumer within the first viewing position prior to transmitting the first focused message.
13. The advertising method of claim 11 wherein:
said steps of transmitting focused messages is performed by an array of loudspeakers.
14. The advertising method of claim 11 wherein:
said steps of transmitting focused messages is performed by parametric audio amplifier systems.
15. The advertising method of claim 11 wherein:
said steps of transmitting focused messages is performed by transmitting said messages using a carrier signal with a frequency above 20 kHz.
