<p>The present invention is provided with a trail point sequence generation unit (11) which uses data for a current position at each point in time measured by a positioning device (100) to generate a movement trail point sequence in which each point has been drawn in a predetermined shape. In the generation of the movement trail point sequence, a point drawn on the basis of a current position determined during simple movement in door-to-door work is drawn in a manner which can be discriminated from a point drawn on the basis of a current position determined during stops at approximately one spot in actual performance of door-to-door work as sales activity, flyer distribution, collection, and various surveys. As a result, it becomes readily apparent as to what locations a worker actually stopped at and what routes were taken.</p> |
