Three things I don’t know about HIG

3 things I learned from iOS HIG:

  1. Before perusing the HIG, I did not know much about the segmented controls. In my old understanding, I thought segmented control is similar to Tab Bars. One is on the top and the other is on the bottom. After reading HIG, I find that Tab Bars is mainly being used for switching between different section of an App, but segmented control is more likely to be used in displaying different views of one page.
  2. I find that the Apple system has a lot of very unchangeable interaction. I used to think designer can be creative of the look of the interaction animation. But after reading the HIG, I found that animation must follow certain principles, or the user will be confused about what’s going on. Such as the progress indicator should look like a spinning icon, the progress bar should look like a track fill from left to right.
  3. I didn’t know HIG has so many different gestures. Such as drag, tap, swipe, flick, pinch, touch and hold. And the most strange one is shake, I never find out that users can shake their phone to undo or redo delete. Knowing these gestures help me to better design the interaction.
