Influencing Human Behavior by Means of Subliminal Stimuli using Scent, Light and Brain Computer Interfaces

We present a proof-of-concept system that integrates ambient lights with a custom made olfactory display that releases subtle burst of scent triggered by brain signals and micro face-gestures such as blinks or jaw clenches. We non-invasively monitor real-time brain activity data using EEG and reflect this information using scent and subtle changes in the ambient light of the environment. This paper discusses different applications for this type of system as well as the implementation of the olfactory display and the supporting software that connects the ambient lights and the EEG sensor. We also discuss the use of subliminal cues like tuning the lighting setup and varying the scent for different kind of behavior changes.
