  • Patent number: 11972073
    Abstract: An electrostatic input apparatus is provided. A measuring unit measures capacitance at a plurality of coordinates of an electrostatic coordinate input unit. A converting unit obtains a reference value of the capacitance and converts the capacitance to difference values according to a distance between the electrostatic coordinate input unit at the coordinates and a finger. A first coordinate calculating unit calculates barycentric coordinates of a contact portion from the difference values for the plurality of coordinates. A cycle determining unit determines whether the difference values at coordinates on a circumference of a circle with a predetermined radius centered on the barycentric coordinates exhibit periodicity of two cycles in one round along the circle. An operation determining unit performs, when the cycle determining unit determines that the difference values exhibit periodicity of two cycles, a determination that an input operation using two or more fingers has been performed.

  • Patent number: 11726617
    Abstract: An electrostatic coordinate input device includes a finger detection unit that detects a proximity position of a finger of an operator on an operation surface by a capacitive sensing method; and a correction unit that, in a case where two proximity positions corresponding to two fingers are detected by the finger detection unit, corrects the two proximity positions so as to increase a distance between the two proximity positions.
