A computing device is described. In an example implementation, the computing device includes a housing including a display screen on a front surface, the housing and display screen being collectively positionable in a plurality of physical orientations, an input device that includes a first selection mechanism and a second selection mechanism, the first selection mechanism being actuatable to adjust a setting of an output of an application displayed on the display screen, the second selection mechanism being actuatable to adjust the setting of the output of the application displayed on the display screen, and an orientation sensor configured to determine which physical orientation of the plurality of physical orientations that the display screen is positioned in, and change a first input polarity of the first selection mechanism to correspond to the determined physical orientation of the display screen.
