@woodinblack :
I have also been kick-starting the prototyping of such an application from my side and provided some insights on this page:
Data Gathering
It is just a prototype so far, but could be worth exchanging some ideas.
@OP_Engr :
Which application did you use for combining Heart Rate and ZEO data on the same graph?
A bit off-topic here (we can continue by PM), but I am also very interested by this issue, what is your setting for monitoring your HR at night? (by the way, the Zephyr BioHarness 3 mentioned by MichaelDKester in another thread seems an excellent candidate for combining Zeo data with breathing rhythms as well).
Otherwise, about research on Heart Rate Variability:
1/ I was also wondering if the algorithm used by sleepimage for computing cardiopulmonary coupling frequencies was somehow supported by the software Kubios (would be interesting to figure this out, and if only HR data is used as input of such an algorithm or if the actigraphy recorded by the sleepimage device would be required as well). You could also check how your HR data can be imported in the software.
Kubios HRV website: http://kubios.uef.fi/KubiosHRV/
2/ Related to this topic, I am surprised that nobody on this forum has mentioned “beddit” so far. Indeed, I have not really figured out when this product could be available, but it seems promising. It relies on a non intrusive set of sensors simply tied around your mattress, and “the sleep staging is carried out by an algorithm that utilizes heart rate variation, respiratory variation and activity information” for computing and displaying in a user-friendly way the following information: sleep staging (wake, light/REM/deep sleep), stress reactions (based on heart rate variability), heart rate curve and average heart rate, and “restlessness index”.
Check out their website: http://www.beddit.com
I also recommend a very nice article presenting the whole approach in detail (“Unobtrusive Online Monitoring of Sleep at Home”, J. Paalasmaa, M. Waris, H. Toivonen, L. Leppakorpi, and M. Partinen, 2012).
Hi Frederic,
These are all topics that I plan on hitting at some point in my thread. Thank you for further information that I can use and for others as well. I plan on referencing this post in my Zeo marketability thread . Slowly, but surely I plan of filling it out. So far it seems more like a monologue than a discussion, but I have hopes that as it fills out it will be come a springboard for similar discussions on other devices, apps, websites, and software we use.
