Input apparatus

摘要

An input apparatus (for example, a mobile terminal apparatus (100)) includes a display unit (60) that displays a plurality of operation position displays (for example, operation position displays (61 to 66)); and a detection unit that contactlessly detects an operation which corresponds to an operation position set in a specific space of a front of the input apparatus in correspondence to each of the plurality of operation position displays. The detection unit includes a first piezoelectric element (an oscillation piezoelectric element (31)) that oscillates ultrasound toward the front space of the input apparatus; a second piezoelectric element (a reception piezoelectric element (21)) that detects the ultrasound which is oscillated by the first piezoelectric element; and a determination unit that determines whether or not an operation is performed on a certain operation position based on a result of detection performed by the second piezoelectric element.

1. An input apparatus comprising:
a display unit that displays a plurality of operation position displays; and a detection unit that contactlessly detects an operation performed on an operation position which is set in a specific space of a front of the input apparatus, which corresponds to each of the plurality of operation position displays, wherein the detection unit includes a first piezoelectric element that oscillates ultrasound toward the front space of the input apparatus; a second piezoelectric element that detects the ultrasound which is oscillated by the first piezoelectric element; and a determination unit that determines whether or not an operation is performed on a certain operation position based on a result of detection performed by the second piezoelectric element, wherein a tactile sensation provision control unit that performs control such that tactile sensation is provided using a second ultrasound to an object which performed the operation using the second piezoelectric element, wherein the second piezoelectric element is configured to generate the second ultrasound at a time other than when the second piezoelectric element detects the ultrasound.
