PROBLEM TO BE SOLVED: To speedily detect a start of a stay with a small power consumption.SOLUTION: A stay estimation device acquires positional information of a user, leaves the history of the positional information, and, on the basis of the history of the positional information, extracts a stay point using parameters including a threshold of a stay time and a threshold of a moving distance. The stay estimation device leaves the history also about the movement of the stay point, and creates a movement prediction model between stay points on the basis of the movement history of the stay points. The stay estimation device updates the acquisition frequency of the positional information on the basis of the positional relationship between the positional information changing from moment to moment and the stay point included in the created movement prediction model, namely a predicted stay point. |
