I have been pretty excited for small devices and what role libraries can have in that space, but the Apple Watch seems pretty exciting especially in terms of added gestures through haptic pressure ("force touch"), obviously all the geolocational, accelerometer stuff, and of course communicating with other devices / doors, controlling screens, etc. This doesn't really have to be about watches specifically, but hey.
For the web, mobile first design really only goes so far as design for a phone, but as the device landscape gets weirder it makes more sense that users won't be interacting through a browser [on these devices], rather interaction with-say-a local library could be contextual and smart.
"I know that you are 100 feet from the library, here are the items available for pickup."
What do you think would be cool, useful, realistic, etc.?
