FIELD: information technology. ^ SUBSTANCE: touch sensor device comprises: a touch sensor for sending an output voltage signal S1, representing presence or absence of an action; a unit for determining presence/absence of an action which, when the output voltage signal S1 assumes a value equal to or greater than a given threshold value, determines that an action has occurred; a unit for determining for determining stability for determining whether or not a differential signal S3 is limited within a given range, said differential signal representing a differential value obtained by differentiating the output voltage signal S1; and a timer which, when the period during which the differential signal S3 is limited within the given range becomes the given period of time or longer, based on that, the output voltage signal S1 assumes a value equal to or greater than the given threshold value, sends a signal for determining switching on S5 and enables an external device to operate. ^ EFFECT: reduced incorrect and unintentional triggering. ^ 5 cl, 3 dwg |
