The 2D Visualizer is a simple demonstration app that allows the user to visualize their brain activity in 2D format. You can choose from four different windows according to what you want to see. The Sensor Status window will show you the connection status for each sensor. Under the Mind Index, you will be able to see the left and right brain activity levels respectively as well as your attention and relaxation levels computed using our algorithms. In the Feature Index window, you will be able to see the different brain signal frequency levels for each sensor, according to the 10-10 EEG sensor placement standards. Finally, under Raw Signal, you will be able to observe the raw signals for each of the channels in or device.
