ABSTRACT:
A system for fragrance sensory stimulation synchronized to a multimedia source connected to an audiovisual display is disclosed. A fragrance generator processes fragrance information from the audiovisual source into a flagrance signal, and a fragrance control system accepts the fragrance signal as an input and generates a control signal and a controlled airflow. In turn, a fragrance delivery system with a plurality of fragrance chemicals in communication with the controlled airflow selectively volatilizes the fragrance chemicals so that a short burst of fragrance is delivered to a user. In certain embodiments, the fragrance delivery system comprises an indexing turret containing a plurality of ports, each containing one fragrance chemical. In another preferred embodiment, a multi-port micro-valve or an array of such valves contains an absorbent material impregnated with a fragrance in each port.
