Optical systems for head-worn computers

A wearable device comprising:

• a display:
• a first one or more sensors;
• and
• one or more processors configured to perform:
• determining a base display image;
• capturing, via the first one or more sensors, an image of a user of the wearable device;
• determining, based on the captured image, a line of sight from the user to a center of the display;
• determining a viewing angle between the line of sight and a horizontal plane;
• determining, based on a difference between the determined viewing angle and a desired viewing angle, that the base image should be adjusted;
• in accordance with the determination that the base display image should be adjusted:
• generating an edited display image, wherein generating the edited display image comprises:
• cropping the base display image to reduce a vertical display size, and
• shifting the base display image with respect to the horizontal plane, the shifting having a magnitude based on the difference between the determined viewing angle and the desired viewing angle and further having a vertical direction based on the difference between the determined viewing angle and the desired viewing angle;
• and
• presenting the edited display image to the user via the display.

A non-transitory computer readable storage medium storing instructions that, when executed, cause one or more processors to perform a method comprising:

• determining a base display image;
• capturing, via a first one or more sensors of a wearable head device, an image of a user of the wearable head device;
• determining, based on the captured image, a line of sight from the user to a center of a display of the wearable head device;
• determining a viewing angle between the line of sight and a horizontal plane;
• determining, based on a difference between the determined viewing angle and a desired viewing angle, that the base image should be adjusted;
• in accordance with the determination that the base display image should be adjusted:
• generating an edited display image, wherein generating the edited display image comprises:
• cropping the base display image to reduce a vertical display size, and
• shifting the base display image with respect to the horizontal plane, the shifting having a magnitude based on the difference between the determined viewing angle and the desired viewing angle and further having a vertical direction based on the difference between the determined viewing angle and the desired viewing angle;
• and
• presenting the edited display image to the user via the display.
