Device-scale user interface elements in iOS Mobile Safari
Another fantastic post by the 37signals crew.
When we set out to build finger-friendly controls for iOS devices in Basecamp, two major constraints informed our design.
In Basecamp on a PC, when you hover over a to-do, milestone, or file, you’ll see edit and delete controls. But as has been covered here and elsewhere on the web, there’s no way to hover on a touch device. So our solution to this first constraint is to show the controls when you tap instead of when you hover.
The second constraint is that the controls must be finger-friendly. That is, they should be sized such that they’re always big enough to operate with a thumb, but never too big to fit on the screen.
