See-through computer display systems

A head-worn display, comprising:

• a left see-through display panel configured to present left digital content corresponding a digital content to at a left field of view to a left eye of a user of the head-worn display;
• a right see-through display panel configured to present right digital content corresponding to the digital content at a right field of view to a right eye of the user;
• a processor in communication with the left see-through display panel and the right see-through display panel, and configured to, when the head-worn display is in a first state, set a first perceived distance from the user to the digital content by
• communicating to the left see-through display panel a portion of the left digital content comprising a subset of the left field of view, wherein the subset of the left field of view comprises a left middle of the left field of view, and
• communicating to the right see-through display panel a portion of the right digital content comprising a subset of the right field of view, wherein the subset of the right field of view comprises a right middle of the right field of view, and
• wherein the processor is also configured to, when the head-worn display is in a second state, adjust the first perceived distance from the user to the digital content to a second perceived distance from the user to the digital content by
• shifting the left digital content onto a left blank area adjacent to the subset of the left field of view, and
• shifting the right digital content onto a right blank area adjacent to the subset of the right field of view.
