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.
