Apple Watch Design Guidelines.
What You Should Have Known Already.
If you are one of the many individuals who believe that the Apple Watch was designed with the sole intent of making all other Apple products obsolete in nature, you may want to think again. The intent of the Apple Watch is to simply provide an alternative device in terms of weight and accessibility. This specific watch will definitely allow you to make the most of your time, especially with the state-of-the-art smart screen.
The screen of the Apple Watch is available in two different sizes: 38 millimeters and 42 millimeters. As expected, the screen is touch-sensitive, though actual gestures are not supported; however, the Apple Watch screen is able to differentiate between taps and holds thanks to the pressure-sensitive setting that the screen contains.
A digital crown on the watch’s side acts as a form of scrolling up and/or down in order to allow the user to not have to continuously touch the screen. The crown can also work for pressing buttons and zooming in and out of the screen.
