As we enter the wearables era, the notification is about to undergo one of its more significant advancements in history. The Apple Watch will improve on the pager from the 1990s and position silent haptic feedback as a notification. The ability to send and receive messages via “taps” on the wrist will turn the modern notification into a communication medium. While the smartphone may have taken the notification and run a little too far with it in the wrong direction, the Apple Watch will likely put the notification on a new, more sustainable path.

Interesting list of historical notifications. I would have started the list with smoke signals, designed to send messages from one hilltop to the next. How about a knock on the door? Or the tippety-tap of Morse code? Or that famous midnight ride?

Good stuff. [Via the always excellent iOS Dev Weekly]
