<p>Aspects relate to placement of navigational controls on the left bottom position, the right bottom position, or both the left bottom and right bottom position on a tablet computer display. The placement selection of the navigational controls can be a function of orientation of a user's thumb(s). A navigational area can be defined with respect to a range of movement of the user's thumb(s) and/or size of the user's thumb(s). Further, the navigational controls can be switched between left-hand control and right-hand control as a function of a user preference. When the display is switched between portrait and landscape mode, the navigational controls can be automatically adjusted as a function of the navigational area and the display mode.</p> |
