You're basically saying I am out of line for expecting a 100 in 1 product to do anything well because why should it? It's 100 products IN ONE!!!
No, I'm not. My point was that it's not fair to compare a single function device that gets 30 hours of 'real time' HR tracking from it's battery with something that does 100 other things as well and say 'the technology is there, why doesn't it work?'.
But to your further point, the Microsoft Band
does track HR well, well enough for what most users will need, and that's based on the as yet
limited info we know about it's HR tracking. What you want is high resolution 24/7 tracking, something that most 'general consumers' will get little or no benefit from. It also may well be that the Band uses other sensors to determine the best times to sample HR and in so doing reduce the number of samples it needs to get accurate tracking.
It really just comes down to false marketing. Microsoft is marketing the "continuous" heart rate monitoring feature IDENTICALLY to the way Mio advertises their continuous heart rate feature (albeit the ONLY feature). Since Microsoft abundantly claims it monitors your heart rate continuously (as Mio does), should it not monitor it continuously? Let's please try to keep the bias out of this (yes, I know that's impossible on message forums but heck I'm stubborn!).
I still believe that this is
not false marketing. The device does measure continuously, it just samples less. And like I said, we don't know how it determines when to sample which might or might not be more complex than just every 20min.
I think MS built this device for an end goal of a comprehensive health analysis and they have made decisions and compromises to achieve that with the tech available. Their intention was not to make the ultimate HR monitor but that doesn't mean that the overall health analysis that you get is any less useful/accurate, they have just made use of other sensors and software to get it. If you have a need to monitor HR specifically in maximum detail then the best way would be with a dedicated HR monitor.
We need to give this device a run for a week or a month, collect some data and then compare that to what you would get from something like the Mio over the same period. And I have no bias here, whatever the results.
I'll also say that when I talk about the 'general consumer' I'm thinking about myself and the people I know. I'm interested in fitness, I run, I cycle, I lift weights, I've got a triathlon event this weekend in fact, but so far nothing that I've heard about the Band and it's HR tracking concerns me. I'll get precise tracking when I'm working out, a good overview when I'm not, I have no doubt that the caloric burn will be accurate (based on HR, GVS & other sensors) and I see no real benefit for me to measure my heart rate at second, or microsecond, intervals 24/7.
