Digital Ink Stroke Order Rearrangement for Text-Like Editing

The patent creates a virtual copy of the digital ink data by generating invisible threshold lines that represent the spatial positions of strokes. This virtual copy can be manipulated through editing operations without affecting the original ink input process, thereby enabling editing capability while preserving input flexibility

The patent introduces threshold lines as an intermediary between the displayed digital ink data and the editing operations. These invisible lines serve as mediators that translate user interactions into meaningful editing actions on the ink data, enabling editing without directly manipulating the ink strokes themselves

The patent performs preliminary action by generating threshold lines at the time of stroke input, before any editing operations occur. These pre-generated lines capture the spatial information needed for later editing, allowing the system to manage stroke order complexity without interfering with the natural writing process

The patent segments the continuous ink strokes into discrete threshold line representations. Each stroke or portion of stroke is associated with its own threshold line, allowing individual manipulation and reordering without affecting the entire ink data set, thereby simplifying stroke order management

The patent creates editable copies of the original digital ink data through threshold line representations. These copies can be freely edited through insertion, deletion, and other operations while the original ink data remains intact, maintaining data integrity while enabling editing flexibility

The patent makes the threshold line structure dynamic and adjustable after input. The system allows modification of threshold line positions, additions, and deletions, transforming the originally static ink data representation into a dynamic structure that supports editing operations while preserving the original input
