Biosensing Headband

Thank you for using the SereniBrain Biosensing Headband. This product is composed of an electroencephalogram (EEG) signal acquisition headband and the “SereniBrain” App. It can collect and decode EEG signals to assess your level of mindfulness meditation and provide visual and auditory biological/neural feedback. It then uses this feedback to change the visual and auditory scenes displayed on your mobile phone, tablet or other terminal device, bringing you an immersive and interactive practice experience which helps you to enter the state of mindfulness meditation.

Packing List

Note: In addition to the above devices, you will also need to provide a mobile phone, tablet or other terminal device and a set of headphones (make sure that the headphones are connected to the phone/tablet/device).

 Headband Overview

1.  As shown in Fig. 2-1, install the forehead electrode, left electrode and right electrode and check whether the headband is properly connected. If you have any questions, please contact customer service.

2. When you need to replace an electrode, pull it out with your fingers and install the new electrode.

3. The sound and light state of the headband in various working statuses is as shown in Table 2-1:
   Table 2-1: Description of sound and light state

4. The main parameters of the headband are as shown in Table 2-2:

4. When charging, the headband will automatically turn off.

3. Wearing the headband
   Adjust the tightness of the headband, put it on your head and slide the left and right electrodes according to the shape of your head to ensure that the three electrodes are stably fitted to the skin without hair trapped between.

Correct ways to wear the headband: as shown in Fig. D on the right.

• Align the ON/OFF button with the center line of the bridge of the nose.
• Keep the lower edge of the front of the headband near your eyebrows.
• Fit the left and right electrodes to the center as much as possible.
• If wearing glasses, keep the headband close to the arms of the glasses.

Common incorrect ways to wear the headband: as shown in the figure below

1. As shown in Fig. 2), the ON/OFF button is not in the middle.

2. . As shown in Fig. 3, the headband is worn too high, away from the eyebrows.

3. As shown in Fig. 4), hair is trapped between the electrodes and the skin.

4. Note: Please ensure that the electrodes make contact with clean skin and do not allow hair or other substances in between, otherwise it will reduce the effectiveness of the device. The ideal wearing position is as shown in Fig. 3-3:

8. After the headband is successfully connected, wear it correctly according to the App tips or the instructions in the Manual before using it.

9. After the headband is successfully connected, it will connect automatically when subsequently using the software. If you wish to cancel automatic connection, press the headband ON/OFF button five times successively.

Viewing the EEG signal waveform

1. This product must be used on the premise that the headband is worn correctly and the EEG signal is stable. After the headband is worn correctly according to the wearing instructions (the headband icon on the homepage is green), click the headband icon as shown in Fig. 3-7 to view the EEG signal waveform.
2. For a short period of time after the headband is worn, the electrode will be polarized, so the waveform will be unstable and the lines will change greatly, as shown in Fig. 3-8. This is normal. If it does not become stable after more than 30 seconds, this indicates that the headband is worn incorrectly or there is a barrier between the electrode and the skin. Please wear it correctly or ramous the harrier.
3. After about 30 seconds, the waveform will become basically stable and the lines will become basically steady. The waveform should be as shown in Fig. 3- 9, indicating that the headband is worn correctly, and you can start mindfulness meditation practice.

Starting practice

1. After ensuring that the headband is worn correctly and the EEG signal is stable (the headband icon on the homepage is green), you can choose a certain practice icon according to your preference, as shown in Fig. 3-10, and start mindfulness meditation practice with the brain- computer interface.
2.  Before starting the practice, select Practice Settings as shown in Fig. 3-11 and click “Start” (by default, the practice difficulty is set to “low” and the practice duration is set to “10 minutes”).
3. After starting the practice, you can monitor your current meditation state through the “mindfulness meditation score”, “visual feedback” and “auditory feedback”, and make real-time adjustments to your concentration level to obtain better mindfulness meditation effects. Mindfulness meditation score: The higher the score, the better the current mindfulness meditation state; the lower the score, the worse the current mindfulness meditation state.
   The comparison table of mindfulness meditation scores and meditation states is shown in Table 3-1:

Table 3-1 Meditation scores and corresponding states

Each practice scenario has its own visual and auditory feedback. Take the Candlelight Meditation scenario as an example: the better the meditation state, the clearer the picture, the brighter the candlelight and the clearer the background music, as shown in Fig. 3-12. The worse the meditation state, the blurrier the picture, the dimmer the candlelight and the fuzzier the background music, as shown in Fig. 3- 13:

Practice skills

• If you have no experience in mindfulness meditation, please focus, relax, follow the guidance, accept your physical discomfort with a non- judgmental attitude and do not feel anxious about a low score. Follow the guidance and feel your breath, and naturally, you will be able to achieve better mindfulness meditation results.
• If you have some experience in mindfulness meditation, please carefully understand the meaning of the guidance, try to further clear your mind, focus on the real feeling of the moment and actively identify and relieve your stress and anxiety so as to extend the duration of your concentration.
• If you have rich experience in mindfulness meditation, please try to broaden your focus to incorporate the flow of perception, thought, emotional content and subjective awareness so as to enter into a deeper state of meditation.
• During practice, you can close your eyes completely or slightly and focus only on the sound changes (auditory feedback), or you can open your eyes and focus on both the image changes and sound changes (visual and auditory feedback). You can choose whichever mindfulness meditation mode you are most comfortable with.
