Non-transitory computer-readable medium storing selected character specification program, selected character specification method, and selected character specification device

A non-transitory computer-readable medium storing a selected character specification program that causes a computer to execute a process comprising:

• detecting a character region indicating a region, in which each character of the displayed character string is displayed on a screen, based on character string display information including a position of a first character of the displayed character string, a character size of each character of the displayed character string, and space between lines of the displayed character strings;
• specifying one or a plurality of strokes designated on the screen based on input operation information;
• and
• specifying one or a plurality of successive characters, in which a ratio of an area of a selected region based on uppermost, lowermost, leftmost, and rightmost points of the one or the plurality of strokes in the character region to an area of the character region exceeds a threshold, as selected character among a respective character of the displayed character string overlapped with the one or the plurality of strokes.

A selected character specification device comprising:

• a character region detection unit configured to detect a character region indicating a region, in which each character of the displayed character string is displayed on a screen, based on character string display information including a position of a first character of the displayed character string, a character size of each character of the displayed character string, and space between lines of displayed character strings;
• a stroke specification unit configured to specify a stroke of a closed curved line designated on the screen based on input operation information;
• and
• a character specification unit configured to specify one or a plurality of successive characters, in which a ratio of an area of a selected region based on uppermost, lowermost, leftmost, and rightmost points of the stroke of the closed curved line in the character region to an area of the character region exceeds a threshold, as selected character among a respective character of the displayed character string overlapped with the stroke of the closed curved line.
