No, not really. Like I said, the amount of calories burned or steps taken are informations with no actual value....
This statement is bit over generalizing and simplifying the value of steps and calories burned, I believe. The numbers themselves are as you state, but when you add context, it has meanings. More importantly, accumulative effect of data collected over time provides trends and pattern that once understood, the user can begin to make either behavioral or physical changes - or both.
Here are couple of real simple examples that anyone can understand:
1) average calorie burn per day (Cal/day) established by one's life routines. Once known for period of month or two, one can use the average at any given day to determine if he/she is not as active as normal or more active than normal. You can then control calorie intake for that day to maintain activity-consumption balance. Cal/day can also provide changes due to mental or physical state. If one finds consistently under burning Cal/day, that discovery alone can be used to interrogate daily habits and know if something else is going on - an early indicator, as it were.
2) For those with type 2, diabetes, physical activity has a great effect on how their bodies metabolizes glucose. By measuring calories burned, one can monitor blood sugar level versus physical activities. Weigh loss that comes with burning more Cal/day than consumed Cals, is also a part of life style change many with this condition must do.
These are just couple of examples and there are many, many others. My thought is this type of monitoring is essentially the dash board of a car with engine temp, rpm, oil pressure and so on.
......"wow, you are active! you are so cool!", or I don't want to be active and then not even fitness band can't change that. But maybe I'm just not seeing the bigger picture.
I'm not trying to mock users of fitness bands! I'm just trying to understand why someone needs this "useless" device to be active and can't just BE active, you know?
I think you've missed the whole point of these fitness bands. For some, perhaps you've captured their intent but for most, its just additional data. What you do with the data is up to the individual but don't you think knowing more is better than knowing less?
Fundamentally, I agree with your point about the human nature. If one is not active, normally, no device is going to change that. Sort of like gym membership. Can you imagine how crowded any gym would be if all the members actually showed up regularly... So when the new toy wears off, the natural state of behavior will return for most. It really takes commitment to make the (life style) change and if these fitness bands can help, why not.
Well, that's the thing, I guess. I run, do different sports... all just beacuse I want to be active. So I'm doing it because I like it, not because I need to achieve some goal set by my fitness band. So, the silver lining here is that I don't get why someone needs to have this kind of device to actual do something....
Do you time your runs? Want to improve your speed or agility? These bands time your runs and distances. If you play sports, like many of us, we are competitive creatures by nature. Wanting to improve our own performance is always there. Again, its not to get your a$$ off the couch and move, its to increase the rate of performance or speed, and so on.
Even if the data collected is not the most accurate (which btw, it really does not matter all that much), the trend is what's important. If MS Band is consistently higher than Mio or some other device, that's fine because your comparing apples-to-apples (sorry no pun intended). If the the change is in the positive direction, then that's what you care about. The absolute value is nice but not nearly as important.
Last, for me, I got the Band because I wanted to know how much calories I was burning when lifting weights and working out. I hate chest straps and cannot really determine how much Cal/day is affected by resistance training. Cardio machines are easy because they all provide the data at various accuracy.
Like most of us, we have a very limited time in a day to workout so knowing how much calories I'm burning during a workout gives me the data to adjust the pace of my workouts to meet my objectives. Again, its just data but for me, I like knowing more than knowing less...
