Abstract

Brain Computer Interfaces (BCI) can be used not only to monitor users, recognizing their mental state and the activities they perform, but also to make decisions or control their environment. Hence, BCI could improve the health and the independence of users, for example those with low mobility disabilities. In this work, we use a low-cost and low-invasive BCI headband to detect Electroencephalography (EEG) motor imagery. In particular, we propose a deep learning classifier based on Convolutional Neural Networks (CNN) and Long Short-Term Memory (LSTM) in order to detect EEG motor imagery for left and right hands. Our results report a 98,2% accuracy in the correct classification. Additionally, we discuss the influence of using raw data over using the data split in frequency bands in the model proposed. We also discuss the influence of certain frequency bands activity over other frequency bands in the task proposed. These results representa promising discovery in order to democratize users’ independence by the adoption of low-cost and low-invasive technologies in combination with deep learning.
