Title:
NOTIFICATION DEVICE AND NOTIFICATION METHOD
Document Type and Number:
Japanese Patent JP2021051033
Kind Code:
A
Abstract:
To provide technology that informs the certainty of a notification in an easily understandable manner.SOLUTION: A first coefficient derivation unit 230a updates a first coefficient on the basis of a first and a third measured value, and a second coefficient derivation unit 230b updates a second coefficient on the basis of a second and the third measured value. A position calculation unit 240 calculates a current position on the basis of the first computation result of the first measured value and first coefficient, the second computation result of the second measured value and second coefficient, and the third measured value. A distance calculation unit 250 calculates the distance between the current position and a target position. An output unit 260 outputs a notification when the distance is smaller than a threshold. The output unit 260 updates the content of output on the basis of a first convergence degree of the first coefficient and/or a second convergence degree of the second coefficient.SELECTED DRAWING: Figure 1
