A researcher on the Imperial School London and the Royal School of Artwork has developed a artistic gadget that’s meant to make olfactory coaching extra attention-grabbing and fascinating. The gadget, referred to as Seent, appears like a miniature arcade cupboard, and it gamifies the olfactory coaching course of.
The {hardware} features a panel with 4 buttons, a five-inch show, and a Raspberry Pi 4 Mannequin B, which controls an array of piezoelectric atomizers. These atomizers every comprise a definite scent answer — phenylethyl alcohol, eucalyptol, citronella, or eugenol. When activated, the atomizers convert the liquid scents right into a superb mist that’s launched via holes on the panel, permitting customers to smell particular odors. This digital supply technique ensures consistency and precision in scent launch, automating the timing and quantity of every odor for a dependable expertise.

Seent’s gamified interface consists of three interactive video games designed to enhance olfactory talents. The primary sport is an easy “press and play” mode, the place members press a button to launch a scent whereas a visible icon of the odor seems on the display. This course of helps customers affiliate every scent with its corresponding visible cue. The second sport is an odor identification train, the place one of many 4 scents is launched randomly, and members should guess which scent it’s by urgent the corresponding button. Lastly, within the odor differentiation sport, customers scent three consecutive scent releases, two of that are equivalent, whereas one differs, and so they should establish the odd one out. Immediate suggestions is supplied throughout these video games, including an attractive, playful aspect that enhances olfactory rehabilitation by encouraging common participation and progress monitoring.
The system has not but been evaluated in person research, so its potential effectiveness is solely theoretical. There are future plans to guage Seent formally to evaluate its utility, nonetheless. Shifting ahead, the gadget may even be improved such that it could possibly moreover be used to hold out olfactory testing procedures, which medical professionals use to evaluate one’s sense of scent.
