Display device, image forming apparatus, and display method

An image forming apparatus comprising:

• a display configured to display information on image formation;
• a first motor configured to change a direction of a display surface of the display;
• an illuminance sensor;
• and
• a processor configured to
• determine a first direction corresponding to a direction from a human sensor or the display surface to the eyes of the operator based on first sensing data output from the human sensor,
• control the first motor so that a normal direction of the display surface is the first direction when an illuminance of light incident from the first direction included in second sensing data output from the illuminance sensor is less than a first threshold, and
• control the first motor so that the normal direction is a second direction different from the first direction when the illuminance of light incident from the first direction is the first threshold or more.

A display method comprising:

• determining a first direction corresponding to a direction from a human sensor or a display surface of a display to the eyes of an operator based on first sensing data output from the human sensor;
• controlling a first motor which changes a direction of the display surface so that a normal direction of the display surface is the first direction when an illuminance of light incident from the first direction included in second sensing data output from an illuminance sensor is less than a first threshold;
• and
• controlling the first motor so that the normal direction is a second direction different from the first direction when the illuminance of light incident from the first direction is a first threshold or more.
