Problems solved by technology

[0003] In this case, the presence or absence of contact is judged by whether the voltage of the detected electrical signal is higher than the threshold value, but the threshold value will change due to the temperature or humidity around the touch sensor
Therefore, if the threshold value is fixed, there are the following situations: even if there is no human body contact, the electrical signal may exceed the threshold value due to temperature changes, and thus it is judged that there is contact; or, even in the case of human body contact, It may also be judged as no contact because the electrical signal does not exceed the threshold

Embodiment Construction

[0032] use figure 1 The touch sensor device of the first embodiment will be described. figure 1 It is a block diagram showing a schematic configuration of the touch sensor device of the present embodiment. In addition, in Figure 1 to Figure 6 In , the same symbol is used for the same structural unit.

[0033] The touch sensor device 1 of the present embodiment is used to determine the action of an external device provided in the touch sensor device, and the touch sensor device 1 includes: a touch sensor 11; The average value calculation unit 12 ; the threshold value calculation unit 13 connected to the average value calculation unit 12 ; the comparison determination unit 14 connected to the output unit 111 of the touch sensor 11 and the threshold value calculation unit 13 .

[0034] For example, the touch sensor 11 is a multi-input touch sensor and has many contact electrodes. Since the capacitance changes, the change is detected as an electrical signal and output from ...

Abstract

A touch sensor device (1) is provided with a touch sensor (11); an average value calculating means (12) for calculating an average value of outputted voltages outputted from an output section (111) of the touch sensor (11); a threshold value calculating means (13) for calculating a threshold value based on the average value; and a comparing/judging means (14), which compares the outputted voltagewith the threshold value and outputs a judgment signal when the comparing/judging means judges that the outputted voltage exceeds the threshold value.

Description

technical field [0001] The present invention relates to a touch sensor device, a control method, a touch panel device and a program. Background technique [0002] In recent years, touch panels used in various industrial equipment use touch sensors that detect which part of the touch panel is touched by a person. The touch sensor utilizes the characteristic that "when a person touches or touches an electrode on a touch panel, it becomes equivalent to a state in which a capacitor having an electrostatic capacity equivalent to that of a human body is connected to the electrode." The change in the electrostatic capacitance formed between the ground point (ground) and the ground point is detected as an electrical signal. [0003] In this case, the presence or absence of contact is judged based on whether the voltage of the detected electrical signal is higher than a threshold value, but the threshold value changes depending on the temperature or humidity around the touch sensor....
