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.
