Introduction

Last updated 4 months ago

Brain Computer Interfaces (BCI) is a system that allows you to control machines using your brain activity directly, rather then through intermediary interfaces like a mouse, keyboard, touchscreen or voice. EMOTIV technology converts brain waves to digital signals that can be used to control an endless number of digital outputs such as games, IoT devices, communication devices and audio/visual content. EmotivBCI is a desktop application for Mac and Windows that allows you view and train the EMOTIV data streams used for BCI. These data streams are the following:

  • Mental Commands allow active control with specific thoughts that you have trained the system to recognize. You can train up to 4 commands per training profile with an unlimited number of profiles.

  • Performance Metrics allow passive and continuous control based on your real time cognitive state, including measurements of focus, excitement, interest, engagement, stress and relaxation. No training is required.

We also offer two additional data streams that are not from the brain directly, but can be applied to enhance your BCI system.

  • Facial Expressions trigger events with movements of your facial and eye muscles. No training is required, but you can train some expressions to make them more accurate and personalized.

  • Motion Sensors capture your head movements which you can apply to move a mouse or trigger other commands.

The personalized training profiles that you create in EmotivBCI can be used with our Node-RED toolbox to control a wide array of outputs including social media, IoT devices and robotics. Your BCI profile can also be used in other third party applications connected to EMOTIV via our Cortex service.

This document is intended to help you get started using EmotivBCI and to understand how to use the various features that it offers.
