Abstract
Official abstract text for this publication.
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.
