aeroMus - EMG Mouse | Triton NeuroTech 2023

This is an EMG armband which implements mouse actions and cursor movements. The armband collects signals from muscle contractions. The OpenBCI Cyton amplifies and digitizes these signals. The data is sent to a computer running the OpenBCI GUI for further processing where we apply a signal processing pipeline to classify these signals based on hand movement, translating muscle contractions into cursor clicks.

We've integrated the Cyton board’s accelerometer to detect 3D movement, which the cursor on your screen will mirror.

The core of our project is a cutting-edge blend of electrical, biomedical, computer engineering. This involves capturing bioelectric signals, transforming these signals into digital data, and then classifying this data into specific commands.

The goal of our team is to make brain-computer interfaces more accessible:)))
