Multi-foldable electronic device comprising sensors

A multi-foldable electronic device comprising:

• a first housing comprising a first sensor;
• a second housing comprising a second sensor;
• a third housing comprising a third sensor;
• a first hinge member coupled between the first housing and the second housing;
• a second hinge member coupled between the second housing and the third housing;
• a flexible display comprising a first display area supported by the first housing, a second display area supported by the second housing, and a third display area supported by the third housing;
• a processor;
• and
• memory storing instructions,
• wherein the instructions, when executed by the processor, cause the multi-foldable electronic device to:
• detect a first angle between the first housing and the second housing using the first sensor and the second sensor;
• detect a second angle between the second housing and the third housing using the second sensor and the third sensor;
• identify usage mode of the first housing, the second housing, and the third housing, based on the first angle and the second angle;
• and
• perform control to turn on or turn off at least one of the first display area, the second display area, and the third display area, based on the usage mode.

• a processor;
• and
• a memory storing instructions that, when executed by the processor, cause the multi-foldable electronic device to
• detect a first angle between the first housing and the second housing using the first sensor and the second sensor,
• detect a second angle between the second housing and the third housing using the second sensor and the third sensor,
• compare the first and second angles to predefined angle ranges corresponding to respective usage states,
• determine, based on the first and second angles and a gravity direction, a visibility ranking among the first, second, and third display areas, select one or more of the first, second, and third display areas for activation according to the visibility ranking,
• migrate a user interface among the first, second, and third display areas responsive to changes in the visibility ranking, and
• when the second angle is within about 80 degrees to about 100 degrees with the first housing and the second housing unfolded, duplicate a user interface displayed on the third display area to a fourth display area disposed on a surface opposite the third display area of the third housing.
