Automatic scroll control method for synchronizing positions of original text and translation, computer program and terminal device

An automatic scroll control method for scrolling an original text and a translation, the method comprising:

• displaying, by a processor of a terminal device, an original text on a first display and displaying a translation corresponding to the original text on a second display;
• setting a reference line of the first display and a reference line of the second display to be located to correspond to each other;
• and
• deriving the reference point and the end point of each of an image included in the original text and the image included in the translation corresponding to the original text,
• when the original text or the translation is scrolled by a drag operation of a user, synchronizing, by the processor, display positions of the original text and the translation such that the display positions of the original text on the first display and the translation on the second display are laterally aligned with each other, by controlling a scroll speed of the original text and the scroll speed of the translation,
• wherein the display positions of the original text and the translation are synchronized with each other by controlling each of the scroll speeds of the original text and the translation so that the end points of the image of the original text and the image of the corresponding translation simultaneously pass through the reference line.

• setting a reference line of the first display and a reference line of the second display to be located to correspond to each other;
• and
• deriving a reference point and an end point of each paragraph of the original text and the translation corresponding to the original text,
• scrolling the original text and the translation so that start points of the corresponding paragraphs of the original text and the translation match the reference line at the time of detecting a flicking operation of the user;
• and
• when the original text or the translation is scrolled by a drag operation of a user, synchronizing, by the processor, display positions of the original text and the translation by controlling a scroll speed of the original text and the scroll speed of the translation,
• wherein the display positions of the original text and the translation are synchronized with each other by controlling each of the scroll speeds of the original text and the translation so that the end points of the paragraph of the original text and the paragraph of the corresponding translation simultaneously pass through the reference line.

A terminal device comprising:

• a display control unit displaying an original text on a first display and displaying a translation corresponding to the original text on a second display;
• a reference line setting unit setting a reference line of the first display and a reference line of the second display to be located to correspond to each other;
• a reference point derivation unit deriving a reference point of each paragraph of the original text and the translation corresponding to the original text;
• an end point derivation unit deriving an end point of each paragraph of the original text and the translation corresponding to the original text;
• and
• a scroll synchronization unit synchronizing display positions of the original text and the translation when the original text or the translation is scrolled by a drag operation of a user such that the display positions of the original text on the first display and the translation on the second display are laterally aligned with each other, by controlling a scroll speed of the original text and the scroll speed of the translation,
• wherein a scroll synchronization unit controlling each of the scroll speeds of the original text and the translation so that the end points of the paragraph of the original text and the paragraph of the corresponding translation simultaneously pass through the reference line.
