Abstract
A position confirmation device is provided. The position confirmation device comprises: a registration portion, which registers event information comprising information of a place where an event is conducted; a setting portion, which sets a safety range capable of being specified as a position of a user during the event from the information of the place and a position specification accuracy of a first mode for specifying the position; an acquisition portion, which acquires position information relating to a position of a mobile terminal specified by the mobile terminal carried by the user; and a transmission portion, which transmits a switching instruction to the mobile terminal when the position indicated by the position information deviates from the safety range set by the setting portion, wherein the switching instruction instructs switching to a second mode for specifying the position by a greater power consumption and a higher accuracy than the first mode.
