Abstract: The present application relates to a smell sensing system (100) comprising a smell delivery device (104) for delivering an olfactory output (110). The smell delivery device (104) comprises a delivery channel (3) for receiving a substance (5a) from a canister (5), the substance (5a) configured to produce an olfactory output (114). The smell delivery device (104) also comprises an output component (7) through which the substance (5a) is emitted. The smell delivery device (104) also comprises one or more airflow generating elements (13) configured to generate airflow to transport the substance (5a) from the canister (5) to the output component (7). The smell sensing system (100) also comprises a smell sensing device (102) for detecting the olfactory output (110) delivered by the smell delivery device (104).

Abstract: A system (100) for generating an olfactory experience comprises a user interface (120) that allows a user to provide a set of input parameters that define a desired olfactory experience. The system (100) further comprises a set of processing modules (104) that convert the set of input parameters into a set of scent delivery instructions for one or more scent delivery devices (106), (108) to follow. The system *100) can allow a variety of desired olfactory experiences to be indicated by a user and then allow those desired olfactory experiences (or suitable approximations or equivalents thereof) to be provided by a variety of scent delivery devices that may be available to the system (100).
