  • Patent number: 11868578
    Abstract: A detector includes a frame that is at least partially formed from metal, electrodes arranged in a coordinate planar direction of an operating surface, the operating surface being at least partially in contact with the frame, the electrodes detecting a user operation that is an approach or contact of a body of a user toward or with the operating surface, and a calculator that obtains a calculation coordinate by calculating an operation position of the user operation on the operating surface based on an electrostatic capacity change in each of the electrodes. The operating surface is divided into areas. The calculator converts the calculation coordinate to a correction coordinate shifted from a boundary of one of the areas toward an inner portion of one of the electrodes in which the electrostatic capacity change is larger than other electrodes, thereby determining that the correction coordinate is the operation position.
