How does it work?
SLIDE 7
BCI Types
Our focus (so far)
- SSVEP
- Motor imagery
Others
- Event related potentials
- Slow cortical potentials
- Neurofeedback
SLIDE 8
SSVEP
Steady State Visually Evoked Potentials
SLIDE 9
Motor Imagery
Wang, Y., Gao, S., & Gao, X. (2006, January). Common spatial pattern method for channel selection in motor imagery based brain-computer interface. Achieved >90% accuracy classifying right hand vs right foot imagery with 4 electrodes!
SLIDE 10
EEG Toolbox
- Our 1st Step towards BCI Application
○ but it’s also a toolbox ○ and it’s all written in python ○ and it’s open source
SLIDE 11
EEG Toolbox
- Data collection and tagging
- Interface
- Plots
- Paradigms
○ SSVEP ○ Motor Imagery
SLIDE 12
Data Logging and Tagging
- Easily collect raw labeled data!
- Accurate labels
SLIDE 13
Interface
Super Simple Gui
SLIDE 14
EEG Toolbox: Plots
SLIDE 15
EEG Toolbox: SSVEP
SLIDE 16
EEG Toolbox: Motor Imagery
- Stimuli (adjustable)
○ Feet ○ Tongue ○ Left hand ○ Right hand
SLIDE 17
Future Goals
