Abstract. Visual and olfactory collaborations affect our living experiences. In this paper, we propose OlfacEnhancer, a pendant to augment real-world olfactory perception synchronizing visual information. We present the compact hardware design that can release seven different scents and the implementation of a computer-vision-based self-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 the application possibilities of OlfacEnhancer in the future.
