Kokoon July Update: Data Collection

Kokoon July Update: Data Collection

Welcome to another Kokoon update!

This will be a quick update as we’re deep in testing – we’re going to talk about our progress with data collection; the results we’ve been getting and our next steps.

In House Data Collection

As mentioned in the last update, we have now begun our data collection exercise to train our algorithm.

With the arrival of our Golden Sample in June, we have built up a series of prototypes to use in beta testing and data collection over the next few weeks.

Our prototypes for data collection

We’ve started collecting data in house and we’ve been running nightly tests over the last two weeks. To do this, we attach clinical grade EEG wet electrodes to the sleeper along with an ECG monitor overnight to record a full night’s sleep, whilst simultaneously recording EEG data via our Kokoon headphones. We’ll be looking to collect data from over 80 night’s sleep from different people in the coming months.

The data recorded via the wet electrodes is combined with the data collected via the headphones and used to further train our algorithms, to increase robustness and accuracy. So far the data collection has been going well and we’re seeing some great results. As our earlier tests predicted, the removal of the head sensor in favour of ear to ear EEG configuration is considerably improving performance and giving us good consistent contact through the whole night.

The diagram above illustrates consistent good quality signal throughout a whole night’s sleep.

With the updated electronics in our golden sample devices we were able to further tune our EEG sensing performance and now, in testing, we’ve been seeing even better performance from the sensors.

External Testing

Earlier this month we sent out a short survey to our UK based backers, asking for volunteers to take our data collection and beta testing forward. Throughout August, we will be progressing our data collection by inviting our volunteers to undertake the same testing as we have been doing in house, using both the wet electrodes and headphones overnight.

We’d like to say a huge thank you, as once again, your support and enthusiasm has been amazing, with a large number of London based backers volunteering to take part. We will be in touch shortly to begin arranging dates for the sleep tests.


We’re continuing to progress according to our schedule posted in the last update and still expect the first units to ship in September.

That’s all for now. We hope you enjoy reading about our latest progress and developments. As always, we love hearing from you either through email or through our social media channels Facebook, Twitter and Instagram.

Thanks all,

The Kokoon Team
