Solution Overview
Problem
Conventional information collection systems face inefficiencies and inaccuracies when converting physical form documents to electronic surveys, requiring expert knowledge, consuming significant time and resources, and often resulting in errors and storage issues due to reliance on direct user input.
Innovation Solution
A system that captures and analyzes images of physical form documents to identify fields, automatically generates electronic survey questions, and correlates response data back into the document, using optical character recognition and image processing techniques to streamline the conversion process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional information collection systems use direct user input to create electronic surveys, then survey administrators can create surveys, but the process requires significant time, expertise, and results in errors and excessive questions
Solution Approach 1:
The system creates an optical copy of the physical form document and uses image processing to extract fields and questions, replacing manual typing and creation processes. This copying approach eliminates human error in transcription and significantly reduces survey creation time while maintaining accuracy.
Solution Approach 2:
The patent replaces the manual mechanical process of survey creation with an automated optical system. Image processing algorithms automatically extract questions and fields from physical documents, substituting human administrators' manual work with automated optical character recognition and field detection technology.
2Adaptability or versatility
If survey administrators manually create electronic surveys from physical forms, then surveys can be digitized, but the process consumes significant computer resources and storage space
Solution Approach 1:
The system extracts only the essential information (questions and fields) from the physical form document image, rather than storing the entire document or creating redundant electronic versions. This extraction process creates a streamlined electronic survey that maintains functionality while minimizing storage requirements.
Solution Approach 2:
The system creates a simplified optical copy of the form's essential elements rather than duplicating the entire physical document. The image processing extracts only the necessary question and field data, reducing storage space while preserving the survey's adaptive capabilities.
3Reliability
If conventional systems administer electronic surveys multiple times due to errors, then data collection can be attempted, but significant bandwidth and computer resources are consumed
Solution Approach 1:
The system performs error prevention in advance by using image processing to accurately extract fields from the physical form before the survey is administered. This preliminary accuracy check prevents the need for multiple survey administrations, cushioning against future bandwidth waste and resource consumption.
Solution Approach 2:
The optical copying and image processing creates an accurate digital representation of the form's fields before deployment, preventing errors that would require re-administration. This upfront copying ensures survey accuracy and eliminates the need for repeated bandwidth-intensive survey distributions.
4Quantity of substance
If survey administrators create excessive electronic questions, then all possible information can be collected, but storage space and processing time increase
Solution Approach 1:
The system extracts only the specific fields and questions that actually exist on the physical form document, rather than creating comprehensive surveys with all possible questions. This targeted extraction reduces processing time while collecting exactly the information needed.
Solution Approach 2:
The image processing creates a precise copy of the form's actual fields and questions, ensuring that only necessary information is collected. This accurate copying eliminates redundant questions and reduces processing time while maintaining complete information collection for the required data.

AI summary
Embodiments of the present disclosure relate to digitally converting physical form documents to electronic surveys. For example, a survey system receives an image capture of a physical form document and analyzes the image capture to identify fields including questions within the physical form document. The survey system creates an electronic survey corresponding to the physical form document based on the contents of the fields (e.g., text, objects). Specifically, the survey system generates electronic survey questions for the fields based on the contents of the fields. After generating electronic survey questions for the fields in the image capture, the survey system provides the electronic survey for display to a respondent. Additionally, the survey system can complete an electronic version (e.g., an image) of the form document including the responses.
