Smartwatch sales are tanking

It was great. but writing on a micro screen is no fun. press and swipe are about as far as it should go with wrist touch interfaces.

I agree with you. I have a mechanical Rolex watch with an automatic winder. I can keep it on my wrist 24/7, even at night. It glows in the dark. I can instantly see the time when I look at the watch. There is no smartwatch in the world that matches these features. And it does all this without me ever having to "charge" it. Yes, I do have to adjust the time once a week because it runs about 1 second fast per day. But that takes me about 5 seconds/week to adjust.

No Smartwatch for me, I think my mechanical watch is much smarter.

FWIW, I said the same thing about smartphones when they came out - who'd want to browse the web on a tiny 4" screen when you've got a 13" laptop? And indeed, I do very little web-browsing on my smartphone; it's generally just used to answer quick questions when I absolutely need information (or, well, when I want to win an argument over dinner :-P).

What made smartphones useful was people discovered new uses that you just couldn't use a computer for. You can't do turn-by-turn navigation with your laptop in the car. It's nearly useless if you're standing at a street corner in an unfamiliar city and want to know where the closest coffeeshop with wifi is. You can't use it to take a picture of the cute little ducks crossing the road and send it to your wife. It does you no good when you want to hail a car to take you home.

People haven't yet discovered similar uses for a smartwatch. It's highly likely that they exist, though. What the watch gives you is hands-free information: you can receive quick, 1-5 second notifications even if you're carrying something or immersed (sometimes literally) in physical activity. I've already found this useful for getting notifications that my founders' group has changed where we're meeting while I'm driving there, or that my wife has already gone to the grocery store, or for checking off items on my shopping list while carrying shopping bags. There are probably other bigger uses waiting to be discovered.

Smart watches don't have any particular niche to capture that other devices don't have. Maybe if they expanded into large screen computers, that would be cool. It'd be nice to have a rolled up monitor on my arm - it'd be great for maps cause I could unroll it with the other hand to get a peek at the map and then let it auto-re-roll itself. Sorry - I don't have a diagram to show you the idea, but maybe you can catch my drift. I'm aware there are some flexible screens already (some organic stuff), but I don't know much about the progress in that area.

The "smartwatch" from Apple and Android is not a good idea. Fitbit and Pebble are closer to the right direction. Apple/Android keep trying to make watch-sized smartphones. But they will never compete with actual smartphones, they will just always be annoying inferior smartphones on your wrist.

The key factor is to consider which senses are optimal UI for each device. Smartphones dominate the visual and audio senses. Smartwatch simply can't compete there. So smartwatch should have a very simple very low power display like the Fitbit and Pebble and maybe a simple speaker/mic.

So what sense is the smartwatch good for? It's touch. There is a lot of potential of using vibrations/touch as a UI. For example, I think the Apple watch vibrates for turns when you do a Maps route. That's a good start. They need to focus more on things like this. There's a lot you can communicate with vibration, kind of like morse code (such as two quick vibrates, a long vibrate, etc.)

And now Apple has a very advanced touch sensor (the new one in iphone 7). Get rid of that silly big screen on Apple watch. Put the touch sensor there. Why not just allow thumbprint scan, wave my watch at a Apple Pay terminal, and buy things? Way less effort than taking out my phone.

These kind of pure touch and vibration UI is a huge open field. And I think Apple somewhat understands this. But they need to make the big step of dropping that screen. Because that's not where the smartwatch is strong. And it would also allow long battery life which is more important for smartwatch. People are used to daily charge for phones. But much less tolerant of that for watches.
