Problems solved by technology

[0005] However, in the operation input device of Patent Document 1, even if the touch sensor is pressed with the same force, the output value from the acceleration sensor varies depending on the pressed operation position on the panel surface, so it is difficult to set a unified judgment threshold.
In addition, when the touch sensor is a two-dimensional flat panel having a predetermined area, the output value from the acceleration sensor varies depending on the installation position of the acceleration sensor, so there is a problem that the accuracy of the input operation based on the touch position varies.

no. 1 approach

[0020] The operation input device 1 according to the first embodiment of the present invention includes a touch sensor 10 as a coordinate detection unit that detects an operation coordinate, and an acceleration sensor 10 as an acceleration detection unit that detects an acceleration at the position of the operation coordinate on the touch sensor 10 . The sensor 20 and the control unit 30 that corrects the acceleration detected by the acceleration sensor 20 based on the coordinate values ​​detected by the touch sensor 10 are configured.

[0021] figure 1 It is a schematic configuration block diagram showing the configuration of the operation input device according to the embodiment of the present invention. Below, according to figure 1 , the configuration of the operation input device 1 according to the present embodiment will be described.

[0023] Such as figure 1 As shown, the touch sensor 10 is, for example, a touch sensor that detects the pos...

no. 2 approach

[0052] The operation input device 1 according to the second embodiment of the present invention is characterized in that it includes the coordinate detection unit, the acceleration detection unit, and the control unit according to the first embodiment. To determine whether there is a touch on the coordinate detection unit.

[0053] The operation input device 1 according to the second embodiment can detect the position coordinates of approaching or touching (contacting, pressing) to the coordinate detecting unit by the coordinate detecting unit, and can detect and judge the presence or absence of the touch (touching, pressing) by using the acceleration detecting unit. . That is, it is possible to detect touch coordinates in a state where the operator has definitely touched the panel surface of the touch sensor of the operation input device. Alternatively, the operation coordinates in the state where no touch (touch, press) is detected by the acceleration detection unit are the...

Abstract

The present invention is to provide an operation input device that is provided with a compensation means for compensating a value outputted from an acceleration sensor on the basis of a touch position on a touch sensor. An operation input device (1) includes a coordinate detector (10) that detects an operation coordinate, an acceleration detector (20) that detects an acceleration at a position of the operation coordinate, and a controller (10) that compensates the acceleration detected by the acceleration detector (20) based on a coordinate value of the operation coordinate detected by the coordinate detector.

Description

technical field [0001] The present invention relates to an operation input device. Background technique [0002] Conventionally, in an operation input device equipped with a touch sensor, when a hand or finger touches a position of the touch sensor without intending to perform an operation input, there is a problem that the touch sensor reacts and an erroneous input is performed against the user's intention. As a device for preventing this problem, there are known touch sensors that detect contact with or proximity to a conductive body, an acceleration sensor that detects shock or vibration, and a detection that is determined to be present when detection by the touch sensor and detection by the acceleration sensor are performed. An operation input device of an input judging unit of an operation input (refer to Patent Document 1). [0003] The operation input device of Patent Document 1 is formed by arranging a circuit board in a housing, and mounting a microcomputer, a touc...
