ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention is related to a broadcast board system, especially to an instant response broadcast board device and method of the same.
2. Description of the Prior Art
The current propagating efficiency of the broadcast board is relatively low. After a design of an advertisement is determined, then the content of the broadcast board must be edited, printed, transported, and changed. Thus the effect thereof is not as fast as we expect.
In supermarkets for instance, or some dedicated display boards, the contents regarding the products exhibited on the broadcast boards are often static including, for example a, playbill, for propagating commercial information.
Further, as to how many people ever see the displayed products, interest of the displayed products, or further have any questions regarding the displayed products are not known by the supplier. Thus the managers of the product supplier or the product suppliers can not know about the response of the market and the effectiveness of the display. Furthermore, the customer could not be advised in time if there are any question regarding the displayed products.
For a supplier or a promotion manager, if there is information about how people are interested in their products, then they may understand market trend rapidly and accurately so to improve selling and advertising programs.
Furthermore, the conventional broadcast boards are not interactive. For example, TV walls or LED broadcast boards that are located in the streets perform only download operations and have no interactive functions.
In conventional broadcast boards, the content is predetermined and the viewer may only watch the fixed information. The broadcast board can not interact with the people viewing the broadcast board so this is not a personalized design.
SUMMARY OF THE INVENTION
The object of the present invention is to provide an instant response broadcast board method and device for viewing customers.
A further object of the present invention is to provide a broadcast board system and device for propagating new broadcasts or information everywhere rapidly.
A still further object of the present invention is to provide a broadcast board system and device for in depth interaction with viewing customers.
A yet further object of the present invention is to provide a broadcast board system and device which is interesting and attractive. Another object of the present invention is to provide a broadcast board system and device which may count the number of people have encountered the broadcast board and may send the statistical information to a host server.
A digital camera or other detecting element on the broadcast board is used to detect the motion of objects including, for example, customers in front of the broadcast board so as to form a microcomputer display broadcast board, wherein the content of the broadcast board may be changed with the motion of the object.
When a customer stops in front of the board is in the effective range of detection and further remains threat for a predetermined time threshold for a while, a menu pattern will be displayed on the broadcast board, thus the customer may select one options on the menu to generate an instruction. Therefore, the relative broadcast or information may selectively interact with the customer thereby.

If further a credit card input device is used together with a camera, the image for those who use the credit card may be transferred to a control center, thus the transaction through credit cards are safely protected.
Broadcast boards are distributed in public places having a great number of people passing through, including the exhibition frames of the supermarket, and the information regarding viewers who have encountered a particular broadcast board is transferred to a host server. Thus the customer information may be concentrated to a host server, and any information of the host server may be transferred to the broadcast boards and downloaded thereby. Of course, the identification number of the broadcast boards may be constructed for selectively performing the downloading the images and programs.
The display content of the broadcast board may be presented by interesting images, planer or stereo, wherein the stereo image may be formed by a multi-layer screens with different depths of views. The displacement relation of each screen is set according to the depth of the views and is matched with the position at the target viewers so a stereo visual feeling is simulated.
The method for controlling a microcomputer and the display of a broadcast board is by the way of analysis the pixels of image captured by a digital camera, it may use an intention identification method or other algorithm.
From the intention identification method, the image of an object is captured by a video camera, then the pixels with respect to the image signal are analyzed by a trend method or a centering method for judging the movement of the object so to generate different instructions for different directions, such as, stillness, slow movements or fast movements. Whereby, a single video camera built with a computer is used to analyze the variation of pixels for determining the movement of the object in (X, Y) coordinates, further including the intention for the movement in z axis, and moreover, a clicking signal output may be generated.
The present invention will be better understood and its numerous objects and advantages will become apparent to those skilled in the art by referencing to the following drawings:
