  • Publication number: 20160246413
    Abstract: A mobile terminal device receives an input of a pressing operation when an operation surface is pressed. A pressing amount detecting unit detects whether or not the operation surface has been pressed. A grip determining unit determines whether or not the housing has been gripped by a user. A threshold adjusting unit adjusts a press detection sensitivity of the pressing amount detecting unit when the housing is gripped by the user and when the housing is not gripped by the user. By this means, it is possible to provide an input device which adequately detects a pressing operation, and a program which is executed by this input device.

  • Publication number: 20160195994
    Abstract: A touch input device includes a touch panel, a press detection signal generating unit and a touch detection signal generating unit. The touch panel is formed by laminating a piezoelectric sensor and a capacitive sensor.

  • Publication number: 20160034089
    Abstract: A touch input device that includes an operation input unit, a control unit, a memory unit and a display unit. The operation input unit includes a pressing sensor and a touch sensor. When obtaining a detected operation position (x, y) based on an operation detection signal from the touch sensor, the control unit compares a signal level DSp of a press detection signal from the pressing sensor and a first threshold THSp. When determining that the signal level DSp is larger than the first threshold THSp, the control unit reads the detected operation position (x, y) obtained immediately before the determination, and fixes the detected operation position (x, y). The control unit determines operation input contents by using the fixed detected operation position (x, y) and a pressing amount based on the signal level DSp obtained at each sampling timing.

  • Publication number: 20160026299
    Abstract: A touch input device that includes a touch sensor and a control unit. The touch sensor includes a base material, a piezoelectric film, a plurality of first detecting conductors and a plurality of second detecting conductors. The base material is a flat plate. The piezoelectric film is made of uniaxially stretched PLLA, and is arranged on one principal surface of the base material. The first detecting conductors are arranged on a surface of the piezoelectric film opposite to the base material. The plurality of second detecting conductors are arranged on a surface opposite to the surface of the base material which abuts on the piezoelectric film. The control unit detects an operation position and a press by using detection signals outputted from the first detecting conductors and the second detecting conductors.

  • Publication number: 20150301657
    Abstract: 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.

    Abstract: A touch input device has a touch sensor, an operation moving amount detection unit, a pressing force detection unit, and a control unit. The touch sensor has an electrostatic sensor, and a piezoelectric sensor, and outputs an operation position detection signal and a pressing sensing signal.

The pressing force detection unit detects a pressing force from the pressing sensing signal. The control unit previously sets threshold value Th of the pressing force, and starts the drag operation when the pressing force is threshold value Th or more. Threshold value Th whose initial value is a maximum value is decreased with time.

  • Publication number: 20150212571
    Abstract: A touch input device includes a touch sensor and a wake-up control unit. The touch sensor includes a piezoelectric sensor and a detection signal generating unit. The touch sensor outputs sensing signals corresponding to displacement amount of a push and relaxation of the push of an operation surface, and a displacement direction. The detection signal generating unit outputs a displacement detection signal from the sensing signal. The wake-up control unit detects a push from a change in a voltage of the displacement detection signal. The wake-up control unit starts clocking upon detection of the push, and generates and outputs a wake-up signal when detecting relaxation of the push based on the change in the voltage of the displacement detection signal within a detection time.

  • Publication number: 20150199061
    Abstract: A touch input device includes a touch panel, a push amount calculating unit and a touch detection signal generating unit. The touch panel includes piezoelectric and electrostatic sensors. The piezoelectric sensor outputs to the push amount calculating unit a push signal corresponding to a displacement amount obtained by pushing an operation surface. The electrostatic sensor outputs touch signals, corresponding to a touch and a non-touch, to a touch detection signal generating unit. The touch detection signal generating unit outputs to the push amount calculating unit the touch detection signals binarized according to the touch and non-touch state. The push amount calculating unit integrates differences between push signals and a reference potential during a touch state, generates a push amount detection signal and outputs the push amount detection signal. This unit resets a reference potential during a period in which a touch detection signal indicating a non-touch state is inputted.
