Brain-Computer Interface for Smart Home Design Based on Machine Learning and Deep Learning Techniques

Summary Researchers built an EEG-based brain-computer interface for smart-home control using a motor imagery dataset from 25 subjects collected with a 64-channel BCI2000 system. Features extracted from a CNN's convolutional layers trained SVM, CNN and LDA classifiers that remove the noise and overlap behind misclassifications and map selected features onto categories an Arduino UNO can act on; the three models reached overall accuracies of 99%, 96% and 99%. The authors say the scheme could let users control smart-home devices with brainwaves, potentially helping older adults and people with limited mobility.
