香り付き映像広告の誘目性と香り放出映像表示装置の検討

摘要

In this paper, the effective method of inducing a glance aimed at the digital signage by emitting a scent is described. The simulation experiment was done using the immersive VR System because there were a lot of restrictions to the experiment in an actual passageway. In order to investigate the eye catching property of the digital signage, the passer-by's eye movement was analyzed. Through the experiment, they were clarified that the digital signage with the scent was paid to attention, and the strong impression remained in the memory. Next, a scent-emitting video display system applying to the digital signage is described. To this end, a scent-emitting device that is able to quickly change the scents it is releasing, and present them from a distance (by the non-contact method), thus maintaining a relationship between the scent and the image, must be developed. We propose a new method where a device that can release pressurized gases is placed behind the display screen filled with tiny pores. Scents are then ejected from this device, traveling through the pores to the front side of the screen. An excellent scent delivery characteristic was obtained because the distance to the user is close and the scent is presented from the front. We also present a method for inducing viewer reactions using on-screen images, thereby enabling scent release to coincide precisely with viewer inhalations. We anticipate that the simultaneous presentation of scents and video images will deepen viewers' comprehension of these images.%近年，映像表示装置は，大画面，薄型化の技術が進み設rn置場所の制約が少なくなっている。壁掛けや壁に埋め込んrnで使用することも可能である。この技術を地下街の通路のrn壁などに電子看板（デジタルサイネージ）として利用するrnと，従来の写真を用いた看板に比べ遥かに融通性がある。
