    As a PhD student in AI, I greatly appreciate your quantifiable approach to comparing smartwatches. May I suggest using correlation coefficient to compare the GPS signals to find out how correlated they are? Also, I would like if you could compare against the correlation coefficient value for GPS signals from a cellphone on your pocket. I think using it would give a quantifiable measure of agreement between bike trip tracks, which is what your channel is all about ;)

    • @DavidAlsh

      Hey, I'm curious about your thoughts on the challenges of applying AI to sleep stage inference.
      Provided you have a sufficiently large dataset of wearer metadata (age, weight, gender, device location, etc), raw sensor data of a target device (fitbit, whoop, etc), and the sleep stage inference results from a reference device - could one be successful in training an ML model that more accurately infers sleep stages?
      According to the results from Rob's research, it looks like the major devices of today are no worse than 30% off a given reading from his reference device - I could be wrong but I don't believe they currently use ML to determine sleep stages.
      I feel it would be difficult getting enough cases for the training data - but if you partnered with a few sleep study clinics, you could have a few thousand cases in a couple years.

  • @tenjisaga
    @tenjisaga 7 месяцев назад +3

    great channel mate, loving the objective evidence-based reviews.. One thing that might enhance understandability might be the units of time along the x-axis. E.g., does 19:10, 19:20 = 7:10pm, 7:20pm? or 19m:10s, 19m:20s? Might seem obvious but I can't be sure... I presume the interval is 10s rather than 10m?

    I'm a bit surprised that the actual sleep detection isn't part of the sleep tracking test. Stage detection is definitely important, but for example Apple Watches just don't detect sleep outside of set sleep schedule, while things like GTS 3 (at least) do quite well to pick up the fact that I sleep whenever it happens.

  • @krollpeter
    @krollpeter Год назад +4

    Unfortunately, Apple watch is the only one that really lives up to claims. I am not going to buy an iPhone for that. I do not like the restrictive Apple environment, their price system, the "unrepairability", and their ways to oversimplify every product.
    The Blood sugar measurement they may introduce into their product will be a hit, if it works same well.
    I think that all smartwatches that have health monitoring functionality should conform to minimum standards. Otherwise, the vendor should say clearly it's for entertainment purposes, and not be allowed to prominently market health functions.

      Never liked apple from the beginnning, about 2 decades ago when i bought my first mp3 player, this was way before smartphones, maybe 25 yrs ago when the Rio was king of mp3 player but there was also the ipod, i hated apple from that moment and avoided them, the design always struck me made for people with special needs, i prefer "normal" design.

  • @dallas77us
    @dallas77us Год назад +2

    - I can't help but noticed between 1:45 and 1:52 where you mention "very little movement," the devices are being violently shaken (shook?).
    - BTW... Why do you not report on SpO2 during sleep on those devices that support that feature? Like Garmin's "all-day and in sleep"? In fact, Garmin is so egregiously inaccurate, their own forums are peppered with "why so bad" and apnea-fear posts, for YEARS. My Garmin reads SpO2 consistently 5-12% lower than actual for sleep or awake spot checks against a Wellue SleepU, an EMAY EMO-80 or a Veridian 11-50K, those three rarely in disagreement, 2% at worst. The Wellue and EMAY are U.S. FDA Class II along with various international medical and industrial registrations and certifications.
    - Thanks for the reports on the Amazfit GTR/S 4. Disappointing. I'm glad I went with Garmin; well built, feature rich and relatively affordable.

    Something I'd love to see in your reviews is step counter performance when attached to the ankle. I want to find a fitness tracker that would calculate my steps while I'm working with a treadmill. I work on the computer so my arms don't move when I'm on it and I can't get step counts. My old fitbit charge 2 used to track accurately but my Garmin Vivoactive 4 is useless when attached to the ankle.

    Hey! Could you maybe try this same watch again (since it performs particularly worse than most), but next time by strapping it to your arm (bicep) with a different band? In the past, I have seen that I get better readings from watches that don't perform well on the wrist and I would be interesting to see if there is actually a difference or just placebo😊.
