Abstract

This article introduces our demonstration content employing a desktop type olfactory display and a head mount display(HMD). An olfactory display is a device that delivers fragrance to one or more users. We developed the olfactory display using a surface acoustic wave (SAW) device and high-speed solenoid valves. Since the SAW device can atomize liquid droplets forcibly based on SAW streaming phenomenon, even low-volatile odor compound can be presented. By using high-speed solenoid valves, it is possible to perform quantitative control in multichannel precisely, so that olfactory display can produce various fragrances. By using this olfactory display together with the HMD, more realistic feeling can be given to the user. We have developed the content using both visual and olfactory cues. Through the HMD, people walk in the maze and get cocktail ingredients in to virtual environment. In the maze goal people can enjoy the scent from olfactory display.
