Method for reducing perceived optical distortion

A method for reducing perceived optical distortion of light output through a dynamic tactile interface, the dynamic tactile interface including a digital display coupled to a substrate opposite a tactile layer, the substrate and the tactile layer substantially transparent, the tactile layer defining a tactile surface, a peripheral region, and a deformable region, the peripheral region adjacent the deformable region and coupled to the substrate opposite the tactile surface, the deformable region disconnected from the substrate, the method comprising:

• transitioning the deformable region from a retracted setting into an expanded setting, the tactile surface at the deformable region substantially flush with the tactile surface at the peripheral region in the retracted setting and offset from the tactile surface at the peripheral region in the expanded setting;
• and
• at a first time, estimating a first viewing position of a user relative to the digital display;
• substantially at the first time, rendering a image on the digital display based on the first viewing position and a profile of the tactile surface across the deformable region in the expanded setting, the image comprising a portion rendered on the display adjacent the deformable region in the expanded setting;
• at a second time succeeding the first time, estimating a second viewing position of the user relative to the digital display;
• and
• modifying a position of the portion of the image rendered on the display adjacent the deformable region based on a difference between the first viewing position and the second viewing position.

• and
• in response to transitioning the deformable region into the expanded setting, modifying the image rendered on the digital display according to the estimated viewing position of the user to compensate for a surface profile of the tactile layer at the deformable region in the expanded setting.
