Apple is famous for attention to detail, but occasionally they miss. Here’s an example.
In the screenshot above, the iOS7 keyboard is shown in its default state, i.e. without capitalization activated.
Something about this bothered me for a while, but I just figured out what it was: The activation color scheme for the
SHIFT is opposite that of the regular keys.
Notice that the regular keys are light with dark text on them. But for the
SHIFT character it’s a dark background with light on top.
This means something to humans.
Based on the precedent set by the keys above (light with dark), one assumes that the
SHIFT key is activated because it’s in the opposite configuration (dark with light), i.e. it tells us the next character will be a capital.
The fix is easy. When you haven’t touched the keyboard, all keys should display the same way—either light with dark on top, or dark with light on top.
