Well, you're asking for feedback, but the question is, just how much are you looking to do with this device? "Communication and routine" could mean anything. Can you give some more detail on what you intend to achieve?
I will tell you this right now though: You'd be going up against absurdly brutal competition, trying to make something like that. There's Apple, with their funky smartwatch thing, for instance. That device is backed up by a giant corporation, AND the fact that it combines with iPhones, one of the most common products out there. There's no competing with that, not without another giant megacorp behind you.
On the other hand, for stuff that's a bit more simple, there's already things like Fitbit. They can track all sorts of health-related stuff and perform other support tasks. They obviously wont have the sheer versatility of Apple's device since they're not attached to a phone, though they likely cost a heck of alot less.
That's what you'd be up against. But there's another element, which is practicality. From what I understand, alot of people that do already have a "smartwatch" device, dont really interact with it all that much or use many of it's different functions. Likely this is because the things are simply too small... interacting with those microscopic touchscreens has gotta be infuriating. If you REALLY wanted your idea to get somewhere, you'd have to come up with something that makes it easier to use than what is already out there. Heck, alot of users have enough trouble getting their phones to do anything complicated (not like anyone reads manuals or watches tutorials, feh).
But you'd also be up against smartphones in any case. Those crazy gizmos seem to do basically everything and everyone already has one.[/QUO
