Dynamic display output adjustment based on user's line of sight

A computer program product comprising:

• one or more non-transitory computer readable storage media;
• and
• program instructions stored on the one or more non-transitory computer readable storage media to perform operations comprising:
• identifying a line of sight of a user relative to a display having an original screen footprint;
• determining an angle of the line of sight relative to the display;
• determining a displacement distance of the user relative to the display;
• calculating a current screen footprint based on the angle of the line of sight relative to the display and the displacement distance of the user relative to the display;
• determining a screen area ratio value for the current screen footprint;
• expanding the current screen footprint proportionally to the screen area ratio value to form an expanded screen area;
• using the angle of the line of sight relative to the display and the displacement distance of the user relative to the display, determining an adjustment needed to correct dimensional distortion of content on the display caused by the angle of the line of sight relative to the display and the displacement distance of the user relative to the display;
• and
• performing the adjustment to the content, wherein the content with the adjustment is displayed within the expanded screen area.

A computer system comprising:

• a processor set;
• one or more computer readable storage media;
