The Apple Watch is not like existing interfaces. Its potential lies in its limitations: It is accessible because it’s tiny and convenient because it’s only meant for seconds-long interactions. Features such as native voice control, haptic feedback, and a digital crown that can be used to magnify, scroll or zoom within apps crack open a whole new world of design requirements and opportunities (see more in sidebar). The smartest companies will do more than offer facsimiles of their existing apps; they’ll create custom experiences that exploit the watch’s unique interface.
This is a really well done piece with some thoughtful Apple Watch mockups for Uber, Foursquare, Instagram, and others.
