Regulation of Brain Cognitive States through Auditory, Gustatory, and Olfactory Stimulation with Wearable Monitoring

Inspired by advances in wearable technologies, we design and perform human-
subject experiments to investigate the impacts of applying safe actuation
(i.e., auditory, gustatory, and olfactory) for the purpose of regulating the
cognitive arousal state and enhancing the performance state. In two separate
experiments, participants are instructed to engage in a working memory task
known as the _n-back_ task. To modulate their brain state, we introduce
various interventions, including listening to different genres of music in the
first experiment, and consuming coffee and smelling perfume in the second
experiment. Employing only wearable devices for human monitoring and using
safe actuation intervention are the key components of the performed
experiments. This dataset contains subjects' **correct/incorrect responses**
along with their **reaction times**. In these experiments, we employed two
Empatica wristbands and one muse headband to collect their physiological data.
The data from Empatica contains participants ' **electrodermal activity
(EDA)** , ** heart rate (HR)**, ** blood volume pulses (BVP)**, ** skin
surface temperature**, ** Photoplethysmography (PPG), **and 3-axis
**accelerometer data.** Using a muse headband, we also collected
**Electroencephalography (EEG)** signals from four sensors. By creating a
dataset that addresses the current lack of publicly available data for
utilizing wearable devices and safe everyday stimuli to manage internal brain
states, our research enables further investigations into machine learning and
system identification. It eventually paves the way for smarter work
environments in the future. The ultimate goal is to develop practical and
automated personalized closed-loop systems that can effectively regulate
internal brain states and enhance the overall quality of life.
