Abstract
One embodiment provides a method for controlling a virtual depth of field perceived by a wearer of a see-thru display device. The method includes estimating the ocular depth of field of the wearer and projecting virtual imagery with a specified amount of blur. The amount of blur is determined as a function of the ocular depth of field. Another embodiment provides a method for controlling an ocular depth of field of a wearer of a see-thru display device. This method includes computing a target value for the depth of field and increasing the pixel brightness of the virtual imagery presented to the wearer. The increase in pixel brightness contracts the wearer's pupils and thereby deepens the depth of field to the target value.
