Cognitive neuroscience study

In this laboratory, various brain recognition studies were conducted based on electroencephalogram (EEG)
 

  1. User tactile preference

  2. Bio-signal-based emotion recognition

  3. EEG-based analysis according to ASMR

  4. EEG-based analysis when using smartphones (games, SNS)

  5. Brain-Brain Interface (BBI)

- User tactile preference

  • It is known that the feeling of touch (preference) when using a product has a great influence on purchase intention, but it was difficult to objectively evaluate the existing survey method because it has many biases. In this lab, we developed a haptic interface that generates various touches (Dr. Rae-Hyun Kim possesses the relevant original technology), and using this, we analyzed the correlation between the user's tactile preference and the corresponding EEG. (IEEE ACCESS, 2018)

- Bio-signal-based emotion recognition

  • A study was conducted to recognize user emotions through various biosignals (EEG, PPG, GSR, Facial expression). In particular, bio-signals and local facial images were measured using glasses-type wearable equipment designed and developed by ourselves. Through this study, emotion-related feature points were extracted (Arousal and Valence coordination) and emotions were judged in real time. The method through feature fusion showed the best classification accuracy, and the study was reported. (IEEE ACCESS in revision)

- EEG-based analysis according to ASMR

  • Preliminarily experiments were performed to see what changes in the brain when watching ASMR images.

- EEG-based analysis when using smartphones (games, SNS)

  • Preliminarily experiments were conducted to see what changes in the brain occur when using a smartphone (game, SNS).

- Brain-brain interface

  • A study was conducted to connect the brains of two people in remote locations (Direct-to-brain communication).
    [Sender: detects motor imagery in EEG signals recorded from one subject / Transmits this information over the internet / Receiver: FUS (Focused Ultra sound Stimulation) neuromodulation on somatosensory area of a second subject]

  • This study was conducted in cooperation with Harvard Medical School and Incheon St. Mary's Hospital. (PLOS ONE, 2017)
