EEG-based applications

We can find so much EEG-based application in computer and biomedical fields. Most of them are in the testing stage because the EEG technologies are still developing. Researchers are working on devices which provide better accuracy and user-friendliness as well. Besides that, most people researching on better features that we can extract from EEG signals and better machine learning algorithms for classification. We can categorize the EEG-based applications into several categories as follows.

  • Medical
  • Security and authentication
  • Gaming and entertainment
  • Educational
  • Neuroergonimics and smart environment
  • Neuromarketing

Here are some working applications we can find on YouTube.

P300 Speller


P300 speller is based on visual stimulations. The user is seeing a matrix of letters on a digital display and capturing the EEG signals from the head at the same time. Then the developed software predicts the letters user wants to type. Besides the speller, there is a mouse which is controlled by using EEG signals (EEG mouse).

Controlling robots


The basic idea of this kind of application is based on mental commands. The system can train for some specific commands and then the user can use those pre-defined mental commands to control the robot. In this video the user controlling the robot arms using his mental commands. Some software like Emotiv control panel also allows us to train it for some mental commands. It’s pretty interesting to play with that kind of software.

We can find some same kind of applications like controlling drones, control mobile phones and BCI exoskeleton

BCI with VR


Virtual reality (VR) is also an evolving technology in computer field. Combining VR and BCI make it more interesting. The video shown above is using separate EEG and VR headsets. But now there are some headsets with both facilities (Announcing the world’s first brain-computer interface for virtual reality)
