Handwriting Input Display Line Width Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing interactive electronic whiteboards require manual adjustment of marker pen handwriting thickness to match the size of written text, which is inconvenient and affects user experience.
Innovation Solution
A method for automatically adjusting the line width of a mark line based on the height of overlapping handwriting content, using handwriting point information to calculate the height and split content into rows for precise adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual adjustment of marker pen handwriting thickness is required to match the size of written text, then the line width can be precisely controlled, but the ease of operation deteriorates due to the need for constant user intervention
Solution Approach 1:
The system automatically adjusts the marker pen line width by detecting the height of handwriting content and calculating the appropriate line width, eliminating the need for manual user adjustment. The device serves itself by using its own detection capabilities to determine the optimal display parameters.
Solution Approach 2:
The system dynamically changes the line width parameter based on the detected height of the first content. By establishing a correspondence between content height and line width, the system automatically adjusts the display parameter to match the handwriting size without user intervention.
2Ease of operation
If automatic adjustment of marker pen handwriting width is implemented based on content height, then the ease of operation improves, but the device complexity increases due to additional detection and calculation functions
Solution Approach 1:
The system uses the existing handwriting detection and display functions for multiple purposes: not only for displaying the first content but also for detecting its height and determining the appropriate marker pen line width. This multi-functional approach avoids adding separate dedicated components.
Solution Approach 2:
The system replaces manual mechanical adjustment with automated digital detection and calculation. Instead of physical controls for line width adjustment, the system uses software-based height detection and parameter calculation to automatically determine the optimal line width.
3Adaptability or versatility
If the line width of mark line is adjusted according to the height of first content, then the adaptability improves by matching different content sizes, but the manufacturing precision requirements increase for accurate height measurement
Solution Approach 1:
The system establishes a dynamic parameter correspondence where the line width changes based on the detected content height. By making the line width parameter dependent on the measured height, the system adapts to different handwriting sizes while using the same measurement mechanism.

AI summary
A method for handwriting input display, a device thereof and a computer-readable storage medium. The method for handwriting input display includes: receiving and displaying a first input of a user, wherein the first input is one or more first contents input in a handwriting way; receiving and displaying a second input of the user, wherein the second input is a mark line for highlighting the one or more first contents, and the mark line contains an overlapping area with the one or more first contents; and adjusting a line width of the mark line according to a height of a first content of the overlapping area.
