Best practices

•

Carefully consider where you place UI components. Try to keep a 15-pixel margin around UI components and around

the edge of the screen, especially along the top and bottom of the screen. Otherwise, users might inadvertently open a

menu or display the application list.

•

Use a target area of at least 5.5 mm for custom UI components, or at least 4 mm if the component extends across the

full width of the screen. It's a good idea to test the size of the target area with users. Components need to be large

enough to touch with a finger, and this size depends on the layout of the screen and the proximity to other UI

components.

•

Add visual cues to encourage users to explore the gestures in your application. For example, you can add a slider that

users can use to adjust a value by dragging a finger across the component.
