Product Description
Its a user friendly and portable BCI system that acts as a EEG acquisition unit plus a Brain control device. This device tracks the state of mind and accordingly help the user to into proper state by guiding him/her using musical feedback and thus train the person to overcome some brain related disorders.
Another application is to control external IoT devices and mobile applications using intentionally generated neurophysiological signals i.e. controlling the application using brainwave. The device can also be used as a normal headphone.
Working
The device has three electrode which pressed on user head to capture the brain signals. The small EEG signals are amplified by a precision amplifier and filtered electronically. The analog data is converted into digital data using a 16 bit ADC IC. The digital data is transmitted to the PC over the bluetooth. A microcontrller is used to interface with the ADC IC and bluetooth module.
The RAW brainwave data is received on the PC and processed and filtered using the software algorithm. The algorithm converts the RAW brain data into different EEG bands (Alpha, Beta, Delta). The algorithm analyze the EEG data and indicates the different state of mind such as Attention, Meditation. These parameters can be used to control the IoT devices.
For the Demo, A Wireless Car is designed which only starts when the user focus on anything like reading the brain changes the pattern of alpha wave. Check the demo video below.
