Superimposed Digital Ink Structuring for Wearable Interfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional handwriting recognition systems struggle to accurately interpret and interact with superimposed digital ink on small or non-visible interfaces, such as those used in wearable devices and automotive environments, due to the irregular positioning and geometrical features of handwritten characters, limiting user interaction and editing capabilities.
Innovation Solution
The system determines geometrical information from character widths and typography parameters to apply a structuring transformation, including inter-character and inter-word spacing, to properly align and display digital ink, allowing faithful reproduction and interaction with the original input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If superimposed handwriting input is allowed on small interfaces, then interface footprint is reduced and no-look input is supported, but character positioning becomes irregular and interaction difficulty increases
Solution Approach 1:
The system segments the superimposed handwriting input into individual character components, determining geometrical information for each character. This segmentation allows the system to process and structure each character separately, resolving the irregular positioning issue while maintaining the compact interface footprint.
Solution Approach 2:
The system applies structuring transformations that reposition characters from their original superimposed two-dimensional layout into a structured one-dimensional sequence along a baseline. This dimensional transformation enables proper interaction while preserving the space-efficient superimposed input method.
2Stability of the object's composition
If digital ink is converted to typeset ink for interaction, then text structure is improved, but original digital ink positioning information is lost
Solution Approach 1:
The system creates a structured copy of the digital ink by determining geometrical information and applying structuring transformations. This copy maintains the textual structure needed for interaction while preserving the original digital ink and its positioning information for faithful reproduction.
Solution Approach 2:
The system changes the parameter representation of the handwriting from raw coordinate data to structured geometrical information including character widths, heights, and baseline positions. This parameter transformation enables both proper text structure and retention of positioning information.
3Productivity
If superimposed handwriting is displayed without structuring, then input speed is maintained, but legibility and editability deteriorate
Solution Approach 1:
The system performs preliminary structuring transformations on the superimposed handwriting immediately after input, determining geometrical information and applying baseline alignment before display. This preliminary action ensures legibility is achieved without requiring additional processing steps that would slow down input.
