Abstract
A head-mountable device can include an optical module that provides a display element that is moveable based on pressure and/or temperature changes within an enclosed chamber. The control mechanisms can directly and/or indirectly alter one or more of the temperature, pressures, and/or volume of the enclosed chamber. As the conditions within the chamber are altered, an extendable member can expand and/or retract to move the display element towards and/or away from a user's eye. The mechanisms for controlling the position of the display element can be actively and/or passively controlled.
