Videodiscs And Surrogate Travel / The Map-Environment Interface

Abstract
The videodisc is the first visual database medium that can provide random access to its contents. As such, it can support simulations that allow a user to control his movement (surrogate travel). In this application, a user is given a map of an area containing a marked course. The user operates a computer to view pictures of the area that have been stored on a videodisc and 'walks' in search of orienteering markers. Using common map use skills such as resection and visual inspection, the user can locate his position on the map and determine that route that will most efficiently locate each marker.
