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. The piezoelectric sensor is connected to the press detection signal generating unit, and the capacitive sensor is connected to the touch detection signal generating unit. The piezoelectric sensor includes a piezoelectric film, and first and second press detecting conductors disposed with the piezoelectric film sandwiched therebetween. The piezoelectric film is disposed such that a polarity of electric charges produced by a press in the piezoelectric film, and a polarity of excited electric charges produced in the piezoelectric film when the capacitive sensor detects a touch become reverse polarities.

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 translation: 当确定变形检测信号的水平大于阈值时，控制器假设在初始检测位置执行触摸操作，并且在假设处于不同于该位置的另一位置处执行触摸操作，并且将位置检测信号输出到处理器 指示两个触摸位置并且基于触摸位置彼此分离。 因此，控制器将变形检测信号转换成与夹紧操作对应的位置检测信号，并将位置检测信号输出到处理器。

Abstract: A pressing sensor includes a piezoelectric film and first and second detection electrodes. The piezoelectric film has a chiral polymer drawn at least in a uniaxial direction, and has a first main surface and a second main surface. The first and second detection electrodes are arranged on at least one of the first and second main surfaces. The first and second detection electrodes are arranged so as to face each other obliquely to the uniaxial direction.

Abstract: A mobile terminal includes an operation surface, a capacitance sensor having a capacitance that changes in response to a touch operation on the operation surface and a touch-operation detection IC that detects the touch operation based on the change in capacitance in the capacitance sensor. When the operation surface is deformed, the touch-operation detection IC obtains a capacitance of the capacitance sensor which has changed due to the deformation of the operation surface, and grasps the change in capacitance of the capacitance sensor, made due to the touch operation, with the obtained capacitance taken as a new reference.

Abstract: A mobile terminal device detects a touch position on a display screen, and detects that the display screen has been pressed and sets a boundary line based on the touch position. The mobile terminal device divides the display screen into first and second screens separated by the boundary line and displays images corresponding to different functions of the mobile terminal device on the first and second screens.

Abstract: An electronic device that provides a number of function modes and operates by selecting one of the function modes. The device includes an audio output unit and a wireless communication unit that execute functions for the function modes. Moreover, a deformation detecting unit that detects deformation of an exterior housing by an external force and a storage unit that stores a correspondence between a deformation pattern and a response operation registered per function mode. The device also includes an operation determining unit that detects the deformation pattern based on the deformation and a control executing unit that reads a response operation of a current function mode associated with the deformation pattern and controls operation states of the audio output unit and the wireless communication unit.

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.
