Sleep Inducing with ASMR Trigger and Binaural Beat

We developed a sleep inducing system using an auditory stimulus. Especially, we combined a 6 Hz binaural beat and an autonomous sensory meridian response (ASMR) trigger. The proposed auditory stimulus could induce both theta activity corresponding to non-rapid eye movement sleep 1 and psychological stability required for sleep.

Dream Detection

We investigated the difference of change between conscious experience and no conscious experience during non-rapid eye movement sleep. Dream could be detected using periods of conscious experience based on brain network

Meta-BCI: Decoding both Learning Strategies and Intention

In this study, we tried to design a novel brain-computer interface (BCI) framework that can decode decisions (movement intentions) and underlying strategies at the same time. We named this novel BCI as a meta-BCI and classified the learning strategies with high accuracy (98%). Moreover, the movement intentions, which is not separable in a conventional BCI framework, has decoded with high accuracy (84%).

Data Collection Paradigm of Emotional Bio-signals

This experiment paradigm collects emotional biosignals including EEG, ECG, and FACE during watching twelve selected emotional movie clips. In the experiment, there are two sessions. Each session includes six movie clips, and the movie clips are arranged in different orders in two sessions. Researchers can use the paradigm for gathering emotional biosignal states.

Prediction for Upper Limb Motion based on Brain Signal Analysis

This study designed deep neural networks which extract spatio-temporal features in EEG. Our network predicts the probability of each task about an input, represented with a bar graph in this demo. In our experiments, our spatio-temporal network made good achievements for motor imagery related EEG classification and also gave a neurophysiological insight to spatial patterns.

Brain-controlled Avatar using CNN for BCI Race

In BCI race game, the subject has to pass the 4 kinds of obstacles to reach the end running course. Subjects performed the 4-class motor imagery task. We decoded EEG signals and identified the subject’s intention using CNN.
