In an event site or the like, a visitor may waste time and effort trying
to find a spot where an event of interest may be taking place because the
visitor is unable to look through the entire site from any particular
spot. An information gathering robot roams in such an event site
typically along a prescribed route, and notes spots of interest to
transmit this information to a data server. The visitor can access the
data server to find a spot of interest of his or her choice substantially
on a real time basis.
