Currently there’s no way to tell what electrode on the head needs adjustment.

Suggestion:

maybe adding the “channel” as a label under/above each circle so users know which electrode needs better fit.

Or.

Go big with a 10-20 system type visualization with circles on the different electrode placements

Or.

Port the signal quality functionality from the mobile app - this actually guides users how to properly wear the crown/notion for max signal quality  :)

# Short description:
Enable relocation of client-side raw data processing to the onboard CPU.

# Why this feature:
Until now, the raw data can only be accessed via streaming - either using the SDK which is currently implemented over a websocket/ Firebase or using streaming technologies like LSL.

This feature is about enabling clients to run algorithms on the powerful onboard processor, so raw data can be processed onboard also with client-side algorithms.

When the brain experiments ends, may be we can automatically download the data instead of going to select what format you wanna download into.(setting preferred way of download). This idea came while we were doing experiment in one of your company's project.

For some implementations, the reference sensor being at site T7 is not ideal, as considerable electroencephalographic signal is effectively subtracted out. If it were possible to add an auxiliary electrode input (e.g., via the Thunderbold port, as some have done w/ the Muse headset - e.g., https://hackaday.io/project/162169-muse-eeg-headset-making-extra-electrode), it would allow for increased sensitivity of some signals say if the electrode were clipped to the earlobe or affixed to the mastoid. Other users might implement an extra electrode at other sites (e.g., FZ, etc.) to increase sensitivity to other types of signals. 

This would not require changing the online reference (i.e., T7), but might provide additional flexibility for offline referencing and/or recording of other scalp locations.

Shut down as much of the device as possible to conserve energy. 

I'm thinking:
* 2-3 CPU cores shut down
* Lower remaining CPUs clock rate to 1.2 GHz

The battery level will drop from 100 to 75 (for example) if I reboot the device. This was fixed in hardware and needs a firmware update to fix for the crown only and not notion 2.

I know the blink events can be pulled out of the EEG data. However that would need to be analysed by a external source instead of on device.

During some of my recordings with the crown and local hotspot (iphone) the crown looses connection in between and then I also loose my recordings for the whole session.

If the crown has some storage for saving data on device & would it be possible to add a fall back logic during recordings so data isn’t lost if it gets disconnected during a session?

This way once connection is back up, crown can then re-upload for the missing time slices.

if I look down at my phone, the app thinks I’m looking down, I think if you should look for a hold in the correct position for 2 seconds, e.g app sees headset out of ideal position, alerts user to look ahead, when user looks ahead, they can see which way to move the headset, they position the headset in the right spot, the headset makes a haptic tap, the user stays like that for 2 seconds and then the warning on screen disappears

My stream of data will sometimes pause. I checked my wifi the connection is good and I check the neurosity console and the brainwaves screen doesn't show anything. It'll pause for like 20 seconds then go back to normal. This is the first time I've observed this.

There should not be much difference except for channel order.

E.g. As a programmer, teach me how to dynamically parse incoming data based on notion.getInfo() channelNames

Crown: `channelNames: CP3, C3, F5, PO3, PO4, F6, C4, CP4`
Notion 2: `channelNames: CP5,F5,C3,CP3,CP6,F6,C4,CP4`

I am testing Crown for recording EEG/ERP data using `eeg-notebooks`, which depends on the `brainflow` python interface and OSC, and I believe that the observed sampling interval was not updated with the Notion2-->Crown. Specifically, when I inspect the timestamps associated with each sample, their modal first difference (i.e., the sampling interval) is 4.0 instead of 3.90625 ms. The former sampling interval would be expected for the Notion2 (i.e., 1000 ms / 250 Hz sample rate), but not the Crown (1000 ms / 256 Hz sample rate).

Right now we can only navigate to purchase the crown. I recommend having a section for add-ons so customers can see everything extra that is available. Like the travel case, or extra cords and the like.

Hello, we are using the crown for our platform for neurofeedback. I love the crown so far and the parietal coverage is great. I am curious if we can eventually add an axu sensor that would allow us to access midline structures (PZ,CZ,FZ). The cingulate is essentially the bridge between the conscious and unconscious mind and midline structures are often used heavily in the neurofeedback community. The addition of this moveable sensor would really open up with the crown can do for the neurofeedback community.

It has proven to us that using the QR code to scan to add devices can be challenging at times - as the quality of cameras vary, sometimes it takes very long to get the device added this way. 

we are thinking, if there's a way (email?) where we can get the deviceID directly associated with any device purchased through Divergence program, we can easily forward it to the therapist users to add device through the web platform. This will save us a lot of support hours struggling with this.

On the Neurosity Console, it is possible to see the raw EEG but it is not possible to define the scaling ourselves. It is only possible to have autoscale on or off. It would be better for us if we could determine the scaling ourselves and enter manual values for the charts.
