BrainAccess HALO Setup
This tutorial goes through the steps required to correctly setup BrainAccess HALO EEG headband for measurements.
More information can be found in the product manual:
Electrodes position
The Halo headband includes the following electrodes:
4 EEG channels positioned according to the EEG 10-20 international system:
• Fp1 and Fp2 (frontal)
• O1 and O2 (occipital)
Reference electrode:
Positioned at the center of the frontal part of the band. All EEG measurements are made with respect to this electrode.
Bias electrode:
The two pads adjacent to the reference electrode function as bias electrodes. They deliver an actively driven common-mode signal derived from bias feedback
channels, which can be configured in the software (default: all channels).
Wearing the device
1. Turn on the device by pressing and holding the power button for a few seconds. If the red LED blinks rapidly and the device does not power on, the battery is low. This indicates you must charge the device before use.
2. Place the device around your head. Make sure it is oriented correctly, the power button must be on the left side of your head.
3. Adjust the fit using the buckle mechanism until the device sits comfortably. The reference electrode should be aligned with the center of your forehead.
4. Adjust the height and position of the rear electrodes; find the inion (the bump on the back of your head) and place the electrodes about 0.5-1 cm above it. Gently shift the electrodes side to side until you feel the pins make contact with the scalp through the hair.
Connect and record EEG signal
1. Plug in the Bluetooth adapter.
Insert the provided USB Bluetooth adapter into your computer. The required drivers should install automatically. If your computer already has a built-in or other compatible Bluetooth adapter, you can skip this step.
2. Download the BrainAccess Board application.
Install and launch our software for connecting, recording, and visualization. Links for download (Windows and Linux) and more information: BrainAccess Board software.
3. Launch BrainAccess Board.
Once opened, the application will automatically scan for nearby devices. If your device is powered on, it will appear in the list, identified by its serial number (printed on the back of the device, behind the rear channels).
4. Connect to the device.
Select your device and click Connect. You will then be able to stream, visualize, and record EEG data directly through the application.
