1. A microcontroller implemented method in a powered device having a power controlled seat or bed adjustable via actuators, comprising:
presenting a first user interface for selection of a posture axis using eye gaze input, the user interface displaying a plurality of selectable virtual user interface controls each corresponding to an adjustable axis;
receiving, by means of an eye gaze camera and logic configured to detect an occupant's gaze for a determined period of time on a portion of the presented first interface that corresponds to a selected one of the plurality of virtual user interface controls, a selection of an adjustable axis;
presenting a second user interface distinct from the first user interface for selection of an adjustment amount using eye gaze input, the selected adjustment amount to be applied to the selected adjustable axis to cause an adjustment to the power controlled seat or bed;
receiving, by means of the eye gaze camera and logic configured to detect the occupant's second gaze for a determined period of time on a portion of the second presented user interface that corresponds to an adjustment amount, a selection of an adjustment amount;
forwarding the selected adjustable axis and the selected adjustment amount to determine a recommended change and/or overriding values regarding posture of occupant to avoid inadvertent dangers or health issues;
receiving the recommended change and/or overriding values;
determining and modifying the selected adjustable axis and the selected adjustment amount based upon the received recommended change and/or overriding values; and
responsive solely to eye gaze input received from the occupant via the first and the second user interfaces and without the occupant typing commands or using oral input, automatically causing actuators to change the modified selected adjustable axis by the modified selected adjustment amount, thereby causing a change to posture of the occupant without the occupant typing commands or using oral input.
