We normally affiliate sights and sounds with reminiscences, however the sense of scent is definitely probably the most strongly linked to reminiscence and emotion. So if it appears like your photograph album or residence video assortment is lacking one thing, as unusual as it might appear, scents may very well be the lacking issue. Possibly all these outdated makes an attempt to construct a Odor-O-Imaginative and prescient weren’t so wacky in spite of everything, huh?
Researchers from MIT Media Lab and Harvard College are definitely hoping not, at the least. They’ve developed what they name The Anemoia System. It makes use of generative AI to extract related data from {a photograph}, then create a customized perfume that’s supposed to enrich it, whether or not that’s to set off emotions of nostalgia or different feelings.

The title comes from the phrase anemoia, which means nostalgia for a time you by no means truly lived. That concept sits on the coronary heart of the undertaking: as an alternative of merely recreating reminiscences, the system fabricates totally new ones via the mixture of picture evaluation, narrative technology, and scent creation. The machine doesn’t goal for photorealism or persuasion. As a substitute, it encourages gradual, reflective, and tactile engagement, turning digital prompting right into a bodily expertise.
The method begins when the consumer inserts a printed {photograph} into the machine. A Imaginative and prescient-Language Mannequin analyzes the picture, producing a descriptive caption. This caption is then handed off to a Giant Language Mannequin (LLM), which identifies a set of potential “topics” within the scene — something from an individual to an object like a bicycle or tree. This classification determines what choices seem subsequent on the machine’s three rotary dials, which function the core of its tangible interface.

Dial One permits the consumer to decide on a perspective throughout the picture primarily based on the topic listing. Dial Two asks the consumer to put that topic inside a timeline — childhood or maturity for residing beings, manufacture or decay for inanimate ones. Dial Three units the emotional tone of the artificial reminiscence, providing moods comparable to calm, joyful, unhappy, or offended. These inputs provide the generative system with a conceptually wealthy set of parameters.
As soon as the consumer locks of their alternatives, an LLM synthesizes them into a brief narrative meant to signify the imagined reminiscence from that chosen perspective. This identical narrative then turns into the idea for a cross-modal translation step, the place the mannequin selects as much as 4 scents from a library of 39 pre-blended perfume oils. Every perfume is annotated with semantic descriptors — notes, feelings, and related ideas — permitting the mannequin to map language into an olfactory “vector” describing how a lot of every oil to make use of.

Reworking this digital scent vector into an actual perfume requires a specialised olfactory show constructed into the machine. At its core is a Seeed Studio XIAO ESP32S3 microcontroller that receives scent-mixing directions from the host system. It controls 4 12-volt DC peristaltic pumps, every linked to a separate vial of perfume oil. By exactly timing the pump activations, the system dispenses milliliter-accurate portions of every part right into a shared mixing vessel. When the perfume mix is full, the consumer removes the vessel to expertise the aroma that accompanies their artificial reminiscence.
Via this mix of AI, scent know-how, and tactile interplay, The Anemoia System provides a brand new, multisensory approach of partaking with historical past, whether or not actual or imagined.
