Presentation technique of scents using mobile olfactory display for digital signage

Abstract

Understanding and attention value of the advertisement will be advanced by adding scents to the digital signage. However, it was difficult to have corresponding one-to-many relationships, movements of users, and precise chronological control of scents. In this study, using mobile olfactory display, we propose the digital signage with scent which takes account of users' movements. The concept of this study is constructing the system having scents, movements, and communication. This system was built by enabling to receive the scent ejection signal from the advertisement, achieve the distance by the image of web-camera, and eject the scents with the strength in accordance with distance, to have the control of scents which accedes to substance of advertisement and positional relationship. As a result of evaluations, the olfactory information was carried down to users with great accuracy. The scents production of the advertisements will be possible with the use of this system. © 2011 IFIP International Federation for Information Processing.
