More Information
Summary: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.
