Directional information delivery system and method
First Claim
1. A directional information delivery system, comprising:
- a wide-angle electromagnetic wave transmitter for transmitting electromagnetic waves from an object to a specified area in wide angle, the electromagnetic wave carrying thereon a channel identification for identifying a channel for transferring information regarding said object;
an information delivery sub-system for wireless transfer of information regarding at least one object via at least one channel; and
a portable client device, comprising;
a directional electromagnetic wave receiver for receiving electromagnetic wave from a wide-angle electromagnetic wave transmitter in a specified direction and for obtaining a channel identification from the electromagnetic wave; and
information reception means for establishing a connection with the information delivery sub-system based on the channel identification obtained by the directional electromagnetic wave receiver and for obtaining information from the channel indicated by the channel identification.

Abstract
A directional information delivery method and system, wherein a wide-angle electromagnetic wave transmitter is attached on each object for transmitting channel identification that indicates the transferring channel of the information of the exhibited item attached with the wide-angle electromagnetic wave transmitter to a specified area in wide angle, while each portable client device is provided with a directional electromagnetic wave receiver. When a user points the client device he/she to an object, it can receive the electromagnetic wave from that exhibited item. Then, the client device obtains a channel identification from that electromagnetic wave, and establishes a connection with an information delivery sub-system based on the obtained channel identification to obtain information about that exhibited item from the channel and to render that information. In this way, a user can select simply by pointing at the exhibited item with the client device, thereby accurately obtaining the information about the exhibited item of interest.
