Patent ID: 6924741

Claim:
A system for displaying guidance information on a floor in a large-scale facility, comprising: a plurality of tag recognition apparatuses located in the facility, each for sensing tag information stored in a tag device carried by a user, said tag information including a tag identifier and position information of the tag device; a plurality of image projectors located in the facility, each for selectively projecting a guidance image to a partial area on the floor; and a facility server communicable with said tag recognition apparatuses and said image projectors, for receiving tag information from each of said tag recognition apparatuses, and analyzing received tag information to select one of said image projectors for each tag device; said facility server comprising: a recognition unit for removing a data entry from a database in accordance with each tag identifier extracted from the tag information received from each of said tag recognition apparatuses, and for specifying a guidance destination and an advance direction based on the position information extracted from the tag information and a retrieved data entry which includes user information and guidance destination corresponding to the tag identifier; an image data server for storing various image data therein and for retrieving image data corresponding to the guidance destination and advance direction specified by said recognition unit; and an image creation unit for creating guidance image signals based on the image data obtained from said image data server, and for transmitting the guidance image signals to said selected one of said image projectors, so that said selected one of said image projectors projects a guidance image to a partial area on the floor near the tag device carried by the user according to the guidance image signals.
