1. An information output apparatus comprising:
at least one processor configured to:
calculate a series of braille information as an activation area on a plurality of expression members protruding or retracting by moving in at least one direction and being sensed by a user when protruding or retracting;
calculate a retraction maintained position of at least one expression member, for which retraction is maintained, in at least one selected from the space between braille columns, the space between braille rows, and the space between braille paragraphs as a non-activation area in the activation area; and

wherein, the non-activation area comprises a first non-activation area, a second non-activation area, a third non-activation area, and a fourth non-activation area,
wherein the first non-activation area includes expression members arranged in between columns of respective braille,
wherein the second non-activation area includes expression members arranged in between rows of respective braille,
wherein the third non-activation area includes expression members arranged in between paragraphs of braille,
