Abstract
Elderly people suffering from diseases like Parkinson’s disease will have difficulty in movement. For such patients, to analyse their health conditions and for diagnosis purpose, doctors may need their EEG. At present, extraction of these signals needs a short hospital visit. In this work, a simple portable brain computer interface using embedded system is developed to help such elderly people at home who may have difficulty in traveling to hospitals. The BCI system developed here utilizes EEG electrodes for signal extraction as well as high gain amplifier assembly, Raspberry Pi 4 for processing and decoding of the brain waves. The proposed system was simulated using Proteus software, fabricated on printed circuit board and interfaced with Raspberry Pi4 board. Google Colab software was used for processing the EEG dataset while integrating with Raspberry Pi4 using python coding These systems will be more practical and effective for usage outside the laboratory.
