Platform for developing a Brain Computer Interface (BCI) Application. The idea is to collect neuronal data via Starstim device, in particular the NIC system.
Our principal purpose is to build brain interfaces that can be used by general people in two applications: gaming and robotic hand control. The brain-computer interface has to establish a communication with the application without the employment muscles. To use the software knowledge about the usage of electroencephalographic (EEG) sensors, signal processing, machine learning and programming skills is required.
This project is subject to several limitations, the first one comes from the motivation itself, and it is that the system must be non-invasive and should rely only brain signals that reach the cerebral cortex. Also, due to the limited amount of sensors for data acquisition only 8 sections of said cortex can be explored at the same time. The type of signal that can be extracted with this limitations enables us to differentiate between two states: whether the region is consideration is under stress or it is relaxed.
So, what can you expect from our work, well here are the objectives we set our minds in:
- Use the data acquired with each sensor, determine the stress state of each region of the brain in a given time (by measuring power in frequency ranges)
- Train a classifier that takes the said data and determines the action the user is thinking about (only two actions are possible)
- Build different gaming platforms to test the classifying algorithm
