摘要： A technique suitable when an air floating video is used as a non-contact user interface is provided. An air floating video display apparatus includes: a sensor for detecting a state of operation including a position of a hand finger of a user with respect to an air region including a plane of the air floating video or an object displayed on the plane; and a fingertip tactile sense generator which generates texture of a sense of touch on the hand finger by forming, based on information detected by the sensor, sound pressure based on an ultrasonic wave in vicinity of a position of the hand finger.
