The tenets of this article apply to FileMaker solutions as well as more traditional apps. The problem is that new, larger phones are too large for our hands (I have one solution that helps, by the way):
As smartphones continue to get larger but our hands don’t, what kinds of design solutions can ensure mobile interactions remain comfortable, quick, and easy on our thumbs? Here’s a few options to consider.
Designing for Thumbs
In his analysis of 1,333 observations of smartphones in use, Steven Hoober found about 75% of people rely on their thumb and 49% rely on a one-handed grip to get things done on their phones. On large screens (over four inches) those kinds of behaviors can stretch people’s thumbs well past their comfort zone as they try to reach controls positioned at the top of their device…
Design considerations are important for easy of use, and to help prevent users from dropping their phones. Edge swipe gestures, floating action buttons, and better control positioning are steps in the right direction. Of course, using two hands is always the best solution, but it’s not always possible.
