A device or system is provided that provides olfactory stimuli, and includes a piezoelectric vibration device that is used to produce scents corresponding to actions performed in a VR or AR environment, or other application. In some implementations, a user interacts with one or more game elements within a game program being executed by a game engine, and responsive to the interaction, the game engine may communicate a series of commands that cause a piezoelectric device of the device to generate scents to be experienced by the user.

Described herein are systems and techniques for generating odor impressions of scents. Some embodiments provide odor impressions in an extended reality (XR) environment (e.g., virtual reality (VR) and/or augmented reality (AR)). The system determines spatial characteristics of an odor impression that is to be generated in the XR environment. The system generates one or more commands for generating the odor impression based on the spatial characteristics. The system transmits the command(s) to a controller for execution. The controller may control dispersal of scented media to generate the odor impression.

The information processing system includes a classification unit, an acquisition unit, a selection unit, an evaluation unit, and a generation unit. The classification unit classifies a plurality of fragrances into segments defined corresponding to a combination of one of first classification items on a first classification axis with one of second classification items on a second classification axis. The acquisition unit accepts input of information related to the first classification axis from the target person. The selection unit determines one of the first classification items based on the information and selects a fragrance for evaluation from each of segments that correspond to the first classification item and whose second classification items differ from each other. The evaluation unit acquires, for each of the fragrances for evaluation, evaluation information of a scent from the target person. The generation unit generates information on the fragrance for presentation based on the evaluation information.

An aroma diffusing system according to an example embodiment includes an aroma diffusing device and a mobile device. The aroma diffusing device includes a wireless communication module. The aroma diffusing device is equipped with first through n-th aroma capsules selected among a plurality of aroma capsules, which emit respective aromatic substances having different scents from each other. The mobile device is connected to the aroma diffusing device through a wireless communication. The mobile device independently controls an intensity of the emission of the aromatic substance of each of the first through n-th aroma capsules, which are installed in the aroma diffusing device, to determine a combination of scents diffused from the aroma diffusing device. The mobile device controls the intensity of the emission of the aromatic substance of each of the first through n-th aroma capsules by digitizing the intensity to an integer value.

An apparatus for performing chemosensory disorder testing includes an application for installation on a mobile computing device. The application includes a set of instructions to receive a scanning signal from a scanner communicating with the mobile computing device, the scanning signal including a unique identifier. The application next identifies a predetermined scent responsive to the scanning signal. The application generates multiple choice display for display on a display screen associated with the mobile computing device, the multiple-choice display includes an indication associated with the identified predetermined scent and at least one indication associated with another scent. The application receives a test response input from the display screen responsive to an input from a test subject attempting to detect the predetermined scent.

A system (1-9) for dispensing, in particular by nebulization, a liquid in an environment (10), this system comprising at least one dispensing device (1-4) having a settable operating parameter and configured to dispense said liquid, a plurality of sensors (6-9), a control unit (5) configured to gather a datum captured by at least one sensor of said plurality of sensors (6-9) and to adjust, based on at least said captured datum, said operating parameter of said at least one dispensing device (1-4), said plurality of sensors comprising at least one air quality sensor, this air quality sensor incorporating a suction fan configured to suck air, the air quality sensor being configured to measure the quality of the sucked air.

The aroma providing device includes: an aromatic holding structure that is detachable and has a plurality of holding spaces in which aromatics are respectively held; a blower device that supplies air to pass through the holding spaces; a plurality of air supply paths through which the air is introduced into the respective holding spaces; an opening/closing mechanism that includes a member that is deformed by a physical stimulus or a chemical stimulus and switches whether to allow the air to pass through or not for each of the holding spaces; and a control unit that controls the opening/closing mechanism.

A fragrance dispenser and a corresponding method of dispensing fragrance, comprising at least one receptacle having a major open end, with a porous diffuser layer occlusively overlying the major open end of the receptacle, wherein at least a sectional area of the porous diffuser layer is removable to uncover a portion of the receptacle to control of the release rate of a fragrance source. The fragrance dispenser may comprise a plurality of receptacles and the porous diffuser layer comprises a plurality of sections that are individually removable to uncover each receptacle. The fragrance dispenser could comprise a removable cover sheet that is peelably detachable from the porous diffuser layer. Porous diffuser layer could be an organic polymeric nonwoven web and/or the receptacle is made of a thermoplastic organic polymeric resin. The fragrance dispenser may further comprise a secondary diffuser layer that has 50% more permeability that the porous diffuser layer.

A method for controlling one or more scent delivery units includes maintaining one or more scheduled events, maintaining one or more scheduled anti-events, and generating, based on the one or more scheduled events and the one or more scheduled anti-events, command data to be communicated to the one or more scent delivery units to control their activation and deactivation. Generating the command data includes identifying a conflicting period of time during which control specified by the one or more scheduled events differs from control specified by the one or more scheduled anti-events and also includes generating command data that gives priority to control specified by the one or more scheduled anti-events. Control for the one or more scent delivery units during the conflicting period of time is in accordance with control logic of the one or more scheduled anti-events and not the one or more scheduled events.
