“Mobile Web forms tend to have significantly more constraints than their desktop cousins: mobile screens are smaller; connection speeds are slower; entering text is harder; and so on. As a result, it’s generally a good idea to limit the number of Web forms in mobile applications and sites. In situations where you do have to get input from people on mobile devices, radio buttons, checkboxes, select menus, and lists tend to fare much better than open text fields.
But constraints breed innovation and mobile Web forms are no different. The limitations of mobile devices have forced developers and designers to find new ways to make providing input faster and easier. Several of these innovations are now making their way back to the desktop and beyond.”
