OlfacEnhancer: A Vision-Based Scented Necklace for Cross-Modal Perception and Olfaction Augmentation

Smell disorders are common, which can impair the quality of life. In this paper, we propose OlfacEnhancer, a pendant for hyposmia patients, which augments real-world olfactory perception synchronizing visual information. We present the compact hardware designthat can release seven different scents and the implementation of a machine-vision-basedself-sufficient system, which includes automatic image capture and real-time object recognition. Besides, we discussed its validity in promoting healthy olfaction and pleasantness through a brief user study. Finally, we present other application possibilities of OlfacEnhancer in the future.
