摘要： An electronic device is provided in which a capacitance of a capacitor that is formed between one or more reference second touch sensor electrodes and at least one first touch sensor electrodes is defined as a first reference capacitance with the capacitor formed when the touch sensor is folded along a folding line. Moreover, a capacitance of a capacitor formed between a left second touch sensor electrode and at least one of the plurality of first touch sensor electrodes is defined as a left capacitance. Furthermore, a capacitance of a capacitor formed between a right second touch sensor electrode and at least one of the plurality of first touch sensor electrodes is defined as a right capacitance. Using these capacitances, a determining unit of the electronic device can determine that a touch sensor is folded if both the left and the right capacitances are greater than the first reference capacitance.

摘要： When determining that a level of a deformation detection signal is greater than a threshold, a controller assumes that a touch operation is performed at an initially-detected position and virtually at another position different from the position, and outputs a position detection signal to a processor indicating that the two touch positions and separate from each other based on the touch position. Thus, the controller converts the deformation detection signal into the position detection signal corresponding to a pinch-out operation, and outputs the position detection signal to the processor.

摘要： A pressing sensor is provided that generates an output voltage of a first polarity by deforming with an operation plate when a part of a user's body touches the operation plate, and generates the output voltage of a second polarity by deforming with the operation plate when the part of the user's body is moved away from the operation plate. Moreover, a calculation unit calculates an electrical parameter integral value by time-integrating an electrical parameter that changes with the output voltage generated by the pressing sensor. The electrical parameter has a third polarity when the output voltage has the first polarity and has a fourth polarity when the output voltage has the second polarity. The calculation unit calculates a subtraction electrical parameter integral value obtained by subtracting a predetermined value having the third polarity per unit time from the electrical parameter integral value.

摘要： A touch input device includes a sensor for detecting a plurality of touch positions at which a touch operation has been performed on an operation surface, a pressure sensor for detecting a pressing operation which has been performed on the operation surface at at least one of the touch positions, and a control unit. The control unit (a) identifies a first of the touch positions as a support position which is not used to input information into the input device by way of movement of the support position, (b) identifies at least second and third of the touch positions as input touch positions used to input information into the input device by way of movement of the input touch positions, and (c) causes the input device to carry out an operation identified by the movement of the input touch positions.
