One thing I don't understand: how does the wristband/app tell when you are awake and when you are asleep? The screenshot shows several spots of "time awake" during the night, how does it know this?
Preordered, anyway. I've always wanted to try this but the price point of similar gadgets have been over the "cool thing to try" level (>2-300 bucks).
It must be extremely motivating to see all of these $5 payments come into your account, too :)
- pkulak 17y agoI tend to move while awake and lie still when I'm asleep. It probably has something to do with that. ;)
- mmelin 17y agoI don't know about you, but I move around a _lot_ during sleep. Sure, if it only knows that I'm awake if I go to the bathroom or kitchen during the night, I understand the difference. Would be interesting to know how it makes the distinction, though.
- drusenko 17y agoYou (supposedly) only move around when you're in certain sleep stages, and not others. When you're moving around, you're still asleep, but you're much more lightly asleep than when you're not moving around, so it's a much more optimal time to wake up and you can also track how "restful" your sleep is.
- petesalty 17y agoTypically, when you enter deep stage sleep your brain turns your normal motor functions off - it's supposed that this is to stop you from hurting yourself while in deep sleep (although some people suffer from sleep disorders where they do move). In lighter stages of sleep this doesn't happen and you do move around.
