Graphic Object Geometry Change for Handwritten Document Editing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies lack efficient methods for integrating handwritten information, particularly corrective information, into electronic documents, due to slow character transcription and the absence of widely accepted standards for character or command input, limiting the use of handwritten input in devices like personal digital assistants.
Innovation Solution
The integration of a digitizing recognizer, such as a digitizing pad or touch screen, allows for the entry and recognition of handwritten information as text, graphics, or commands, with error tolerance in location and conversion to machine-readable format, using a recognition mode that can be applied concurrently or after entry, and incorporating it into documents through emulated keystrokes or running programs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If handwritten input is used for data entry, then ease of operation is improved, but character transcription speed deteriorates
Solution Approach 1:
The patent replaces manual character-by-character transcription with an automatic recognition system that captures handwritten input and converts it to digital text automatically, eliminating the mechanical process of individual character entry while maintaining the natural flow of handwriting
Solution Approach 2:
The patent introduces a recognition system as an intermediary between the handwritten input and the final digital text, which automatically processes and converts the handwriting into machine-readable format, resolving the contradiction between ease of handwriting and transcription speed
2Adaptability or versatility
If handwritten input is used, then adaptability is improved, but lack of standardized input methods worsens reliability
Solution Approach 1:
The patent transforms the variable parameter of handwritten input into a standardized digital format through automatic recognition, maintaining the adaptability of handwriting while ensuring reliable, consistent output that can be processed by standard systems
Solution Approach 2:
The patent replaces the unreliable manual transcription process with an automated recognition system that consistently converts handwritten input into standardized digital text, eliminating variability in the conversion process while preserving the flexibility of handwriting
3Ease of operation
If location precision is relaxed with error window, then ease of operation is improved, but measurement precision deteriorates
Solution Approach 1:
The patent applies partial precision by allowing an error window for location input, where the system accepts input within a acceptable range rather than requiring exact precision, thereby improving ease of operation while maintaining sufficient accuracy for document integration
Data Source
AI summary
A computing device includes a memory for storing information about graphic objects including locations of the graphic objects, a display for displaying a representation of at least a portion of the information, a surface or pointing device for detecting an indication of a change and one or ore processing units. In response to detecting the indication, the one or more processing units are configured to automatically change a geometry of at least one graphic object of which at least one location is the same as of at least one other graphic object, the change includes a change in at least one location of the at least one graphic object, and at least one location of the at least one other graphic object is unchanged, and automatically change at least a portion of the representation, and the display is configured to display at least a portion of the changed representation.
