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.

Abstract: An input device includes a top panel having an operation surface, a detection unit configured to detect a capacitance corresponding to a distance between the operation surface and an object, and a controller configured to determine, based on a detection result from the detection unit, a relative state between the operation surface and the object to be one out of a non-detection state and a plurality of states. The controller measures, for each of the plurality of states, a duration in which the capacitance is greater than or equal to a corresponding one of capacitance thresholds set for the plurality of states, and determines, using the durations and the time thresholds and capacitance thresholds set for the plurality of states, the relative state to be one out of the non-detection state and the plurality of states.

Abstract: A coordinate input device includes a plurality of detection electrodes arranged in a grid shape, a coordinate calculation unit that calculates coordinates representing a proximity position of an object on a basis of changes in capacitances of the plurality of detection electrodes, and an output unit that outputs the coordinates calculated by the coordinate calculation unit. The coordinate calculation unit calculates the coordinates using each of a first calculation method and a second calculation method. In a case where two objects are detected using both the first calculation method and the second calculation method, the output unit outputs the coordinates calculated using the first calculation method in a case where a distance between the two objects is greater than a predetermined first threshold, and outputs the coordinates calculated using the second calculation method in a case where the distance between the two objects is less than a predetermined second threshold.

Abstract: A contact determination device includes a sensor measuring a contact degree of a body to be detected with an object, a contact determination unit determining whether the body to be detected is in contact with the object, based on a reference value, and a correction unit correcting the reference value, in which a cumulative value is obtained by accumulating a fluctuation amount of the detection value from a contact start time of the body to be detected with the object during a period in which the body to be detected is in contact with the object, and when the detection value increases as the contact degree increases, the correction unit corrects the reference value, based on a maximum value of the cumulative value, or when the detection value decreases as the contact degree increases, the correction unit corrects the reference value, based on a minimum value of the cumulative value.

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.

Abstract: An input apparatus includes a plurality of electrodes spaced apart from each other, a signal processing unit configured to output an input signal depending on a change in a capacitance of each electrode, and a determination unit configured to determine whether an operation object comes in a proximity of at least one of electrodes based on input signals output from the signal processing unit. The determination unit makes a determination such that in a case where one of the input signals is greater than or equal to a first threshold value and an integral value of another of the plurality of input signals in a predetermined integration period is greater than or equal to a second threshold value, it is determined that an operation object has come in a proximity of an electrode corresponding to the one of the input signals.
