Currently, Dexster Smith and Joel Bellenson, founders of the company DigiScents, are developing iSmell, a plug-in device for the computer that contains a palette of scented oils that can combine to create distinct smells. Like MP3 players that download music from the Internet, DigiScents take orders from "ScentStream" software, translating digitized scents to the iSmell. Smith and Bellenson have compiled thousands of scents into a standardized Scent Registry which they plan to integrate into video games and websites.
Since smell is strongly tied to memory and emotion, Smell-O-Vision will be a powerful way to reinforce ideas.
