Method for inserting characters in a character string and the corresponding digital service

A non-transitory computer readable medium having a computer readable program code embodied therein, the computer readable program code being adapted to be executed to implement a character input method in a digital device comprising an input surface for inputting characters and an output surface for displaying characters, the output surface comprising a recognition area and an insertion area, the character input method comprising:

• firstly displaying a string of characters using the recognition area and the insertion area as a display region for the firstly displaying;
• in response to an interaction of a user with the input surface, selecting a position within the string of characters between a first character and a second character displayed on the output surface, the second character being consecutive to the first character within the string of characters;
• secondly displaying, in the recognition area, a first part of the string of characters ending with the first character, while masking, in the insertion area, a second part of the string of characters starting with the second character;
• detecting at least one input stroke entered manually in the insertion area;
• performing handwriting recognition to convert the at least one input stroke into at least one recognised character;
• inserting, at the position within the string of characters, the at least one recognised character;
• and
• firstly scrolling the string of characters in the recognition area so as to display, in the recognition area, at least part of the at least one recognised character that was inserted into the string of characters.

A system for inputting characters, the system comprising:

• an input surface for inputting characters;
• an output surface for displaying characters, the output surface comprising a recognition area and an insertion area for accepting character input;
• a non-transitory computer readable medium including instructions;
• and
• a processor that is operably connected to the input surface, the output surface, and the non-transitory computer readable medium and that executes the instructions to perform operations comprising:
• firstly displaying a string of characters using the recognition area and the insertion area of the output surface;
• selecting, in response to an interaction of a user with the input surface, a position within the string of characters between a first character and a second character displayed on the output surface, the second character being consecutive to the first character within the string of characters;
• secondly displaying, in the recognition area, a first part of the string of characters ending with the first character, while masking, in the insertion area, a second part of the string of characters starting with the second character;
• detecting at least one input stroke entered manually in the insertion area;
• performing handwriting recognition to convert the at least one input stroke into at least one recognised character;
• inserting, at the position within the string of characters, the at least one recognised character;
• and
• firstly scrolling the string of characters in the recognition area so as to display, in the recognition area, at least part of the at least one recognised character that was inserted into the string of characters.
