Using Brain-Computer Interfaces to detect emotions

Wait… but first, what are BCI’s?

This is a sample graph recording a focal spike of a seizure

Detecting emotions

The study

This is a view of potential electrode placement looking down at the top of the head.
  • Anger was linked to theta waves
  • Sadness was linked to both delta and theta waves
  • Thrilled was linked to alpha waves
  • Shock was linked to every wave, but most noticeably theta and delta waves

Key takeaways:

  • Understanding emotion is extremely important and is a big factor in our communication
  • Brain-computer interfaces use your brain signals to communicate with computers
  • Electroencephalogram (EEG) can record the data from your brain waves on graphs
  • There are 5 types of brain waves, Alpha, Beta, Delta, Gamma, and Theta, and they each correspond to a level of alertness
  • A study was done in 2016 on detecting emotions and used an EEG cap. The results were such that anger, sadness, thrilled, and shocked were linked to theta, delta and theta, alpha, and every wave (respectively)
  • The implications and possibilities of a better understanding of emotions are endless and can include diagnosing and treating mental health disorders.
