  • Publication number: 20200386831
    Abstract: At a reference position within a first plane, a magnetic field to be detected has a first direction that changes within the first plane. A magnetic sensor includes an MR element. The MR element includes a magnetic layer having first magnetization that can change in direction within a second plane. The first plane and the second plane intersect at a dihedral angle ? other than 90°. The magnetic field to be detected can be divided into an in-plane component parallel to the second plane and a perpendicular component perpendicular to the second plane. The in-plane component has a second direction that changes with a change in the first direction. The direction of the first magnetization changes with a change in the second direction. A detection value depends on the direction of the first magnetization.

    Abstract: An information presentation device according to an embodiment includes a contour extraction unit, an abstraction processing unit, and a contour correction unit. The contour extraction unit extracts a contour of each structural object included in data showing a layout of a plurality of structural objects. The abstraction processing unit abstracts a contour of each structural object extracted by the contour extraction unit and draws the abstracted contour on a plane grid surface in which grid lines in two directions orthogonal to each other are drawn. The contour correction unit corrects, among contour lines to constitute a contour abstracted by the abstraction processing unit, a contour line deviating from both of the grid lines in the two directions so as to match a grid line in at least one direction of the grid lines in the two directions.
