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.

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.

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.

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.

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.

Abstract: A touch input device includes a position detecting sensor which detects a touch position on an operation surface. A press detecting sensor detects a press on the operation surface. A position detecting sensor alternatively and repeatedly applies and stops applying a drive signal to the position detecting sensor. The position detecting sensor detects a position detection signal output from the position detecting sensor and discharges a charge of the position detecting sensor during the period in which the drive signal is not applied to the position detecting sensor. A press signal detector detects a press detection signal outputted from the press detecting sensor during a period during which the drive signal is not applied to the position detecting sensor. Consequently, it is possible to detect a pressing amount without being influenced by touch position detection processing.

The device includes a housing for the object that has a shape that can be held by an operator and a piezoelectric sensor attached to the housing. Moreover, a detecting unit can detects a holding state of the housing by using a fluctuation amount of an output voltage of the piezoelectric sensor.

The piezoelectric film produces charges when stretched and contracted in response to a displacement of the housing that are outputted as a voltage to the detecting unit. When detecting that the output voltage significantly fluctuates, the detecting unit identifies that the object is being held.
