Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multi-trajectory drawing is performed using periodic touch point acquisition and matching, then the basic trajectory tracking function is achieved, but trajectory linking accuracy deteriorates due to unmatched touch points causing breakpoints
Solution Approach 1:
The patent introduces classification groups as an intermediary structure to bridge breakpoint trajectories and potential matching trajectories. By grouping trajectories based on spatial and directional relationships, the system creates a mediator layer that facilitates accurate matching between breakpoints and subsequent touch points, resolving the accuracy-reliability contradiction.
Solution Approach 2:
The patent performs preliminary classification of trajectories into groups based on spatial position and directional vectors before the actual matching process. This preliminary organization of trajectory data enables faster and more accurate matching when breakpoints occur, preventing trajectory linking errors before they propagate.
2Productivity
If trajectory matching is performed for all current trajectories with current touch points, then trajectory updating is simplified, but computational complexity increases due to the need to process multiple trajectories and determine classification groups
Solution Approach 1:
The patent segments the set of all current trajectories into multiple classification groups based on spatial position and directional characteristics. This segmentation divides the computational task from processing all trajectories globally to processing smaller subsets locally, reducing the computational complexity while maintaining updating efficiency.
Solution Approach 2:
The patent applies different processing strategies to different classification groups based on their specific characteristics. By determining compensation points locally within each group rather than globally across all trajectories, the system reduces overall computational complexity while maintaining accurate trajectory updating for each group.

AI summary
The present application relates to a multi-trajectory breakpoint tracking method, system, large screen or computer-readable storage medium, which comprises: an obtaining step: receiving a current touch signal for tracking a current trajectory group and obtaining a plurality of current touch points according to the current touch signal; a determination step: determining whether each of the current trajectories in the current trajectory group has a matched current touch point or not; a compensation step: determining a current-round classification group which a trajectory vector of the breakpoint trajectory is in, determining a compensation point matching the breakpoint trajectory, and determining the compensation point matched with the breakpoint trajectory; an update step: adding each of the last trajectory points to the current trajectory matched therewith.
