METHOD AND DEVICE FOR CONTROLLING SPATIAL DISTRIBUTION OF SMELL, AUDIOVISUAL SYSTEM AND CUSTOMER GUIDE SYSTEM

摘要

PROBLEM TO BE SOLVED: To two-dimensionally and variably control a position of a smell source.SOLUTION: An air flow having a smell is collided with the other air flow to change a direction to the side of a user, a spatial distribution of a smell in which the source of the smell is present at a part where the air flow has collided is formed, the two air flows facing each other are collided, and the air flow having the smell and the other air flow are produced. Thus, the position of the smell source is two-dimensionally and variably changed.
