Air floating video display apparatus

A method of forming an air floating video, the method comprising:

• detecting a state of operation including a position of a hand finger of a user or a substance held by the user with respect to a space region including a plane of an air floating video or an object displayed on the plane;
• detecting an ultrasonic wave in vicinity of the position of the hand finger or the substance held by the user;
• generating texture of a sense of touch on the hand finger or the substance held by the user by forming sound pressure based on the ultrasonic wave in vicinity of the position of the hand finger or the substance held by the user;
• and
• controlling output of audio including determining whether audio to be output requires high confidentiality, wherein
• in response to the audio requiring high confidentiality, detecting a position of a face of the user based on an image of the user captured by an image-capturing apparatus, and outputting audio toward the vicinity of the face of the user, and
• in response to the audio not requiring high confidentiality, outputting the audio to the vicinity of the position of the hand finger of the user or the substance held by the user.

A non-transitory computer readable storage device having computer readable instructions that when executed by circuitry cause the circuitry to:

• detect a state of operation including a position of a hand finger of a user or a substance held by the user with respect to a space region including a plane of an air floating video or an object displayed on the plane;
• detect an ultrasonic wave in vicinity of the position of the hand finger or the substance held by the user;
• generate texture of a sense of touch on the hand finger or the substance held by the user by forming sound pressure based on the ultrasonic wave in vicinity of the position of the hand finger or the substance held by the user;
• and
• control output of audio including determining whether audio to be output requires high confidentiality, wherein
• in response to the audio requiring high confidentiality, detect a position of a face of the user based on an image of the user captured by an image-capturing apparatus, and output audio toward the vicinity of the face of the user using a super-directive loudspeaker, and
• in response to the audio not requiring high confidentiality, output the audio from the vicinity of the position of the hand finger of the user or the substance held by the user.
