PROBLEM TO BE SOLVED: To provide an acoustic device or the like capable of speedily determining an object that requires voice guidance with stereophonic acoustics.SOLUTION: On the basis of the state of a user, a voice AR device determines any arbitrary object, among objects around the user, as an object of an attention destination of the user. After the lapse of a predetermined determination time from the timing in which the object is determined as the object of the attention destination, the voice AR device determines the object of the attention destination as a target. Further, in the case where the object of the attention destination is determined as the target, the voice AR device generates an acoustic signal that outputs a voice of a voice source corresponding to the target while virtually localizing it at a position of the target, In the case where an object positioned in any other direction than a direction of forward movement is determined as the object of the attention destination of the user, on the basis of an angle formed from the direction of forward movement of the user and a direction of a body of the user, the voice AR device then decreases a remaining time until elapsing the predetermined determination time. |
