Progress in BCI in SSVEP-based Spellers
SSVEP-based spellers, a common BCI application, have improved in information transfer rates over the years. In the previous post we discussed the fundamentals of SSVEP-based BCI and the parameters that […]
BCI Using Steady State Visual Evoked Potentials
Steady State Visual Evoked Potentials uses different frequencies of visual stimulii to distinguish between objects in BCI applications and have relatively high information transfer rates. Evoked potentials are most commonly […]
Implementations of the P300 BCI Speller
The P300 speller is a common Brain Computer Interface (BCI) application. It has many variations designed to improve its accuracy and speed. This article outlines three common implementations. The P300 […]
Brain Computer Interface(BCI) with the P300
The P300 Event Related Potential or ERP is an EEG feature commonly used in BCI applications. It has some advantages but also some significant practical challenges and shortcomings. In the […]
A Primer on Brain Machine Interface
What is involved in a Brain Machine Interface (BMI; also called Brain Computer Interface or BCI) set-up? Here is a primer on paradigms for BMI or BCI. The idea of […]
1001 Apps that Use Your Brain Waves
From neurofeedback and brain training to video games, apps that make use of your brain waves are growing in numbers and possibilities. It’s December 2014 and I’m sitting on a […]
The World as Laboratory
Using EEG to understand the relationship between the human mind and its environment. A future where machines, buildings and environments can better adapt to human bodies, minds, and purpose is […]
