Abstract
Scents can be used to remind a person of his/her memory, such as scheduled events. Researchers have developed systems to emit scents associated with events, but with most of previous systems scents reach the unspecified number of people because they simply diffused the scent. We propose a schedule notification system by using a scent projector that can deliver scents to a specific user. We conducted two experiments: first one was to confirm the ability to deliver scents locally, by asking two subjects sitting side-by-side whether they could notice the smell when the system aimed one of two subjects. Second experiment was whether the subject could distinguish the kind of scent, when one of two kinds of scent was delivered. The results showed that the system could deliver scents quite locally, and subjects could successfully distinguish the kind of scent. With these results, we could show the feasibility of informing scheduled events personally by using multiple scents.
