With the steadily increasing utilization of touch screen interfaces, new requirements and design considerations have become more prevalent along with the design flaws that don’t accommodate finger widths. This is made obvious when button placement comes into play. While the point of a cursor is far more easily controlled, the larger area needed for touch can cause frustrating user experiences. Real estate is limited but should not be the overriding factor in the layout of a mobile UI.
Some helpful tips include placing a “Delete” or “Cancel” buttons in an area that is not as active in its use as other areas on the screen. Keep buttons that are used throughout the screen architecture in a consistent place. And determine the essential features needed so as to allow for the cleanest button placement possible.
