Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Analog notations and annotations, such as handwritten notes and voice data, are difficult to search and digitize effectively, leading to loss of data and decipherability issues, which hinders their use in digital media.
Innovation Solution
A method and system for searching analog data using analog search terms, where mobile devices with touch-sensitive displays and pressure sensors capture position, pressure, and time data for writing, facial expressions, and voice features, allowing direct search and retrieval of analog content without conversion to digital text.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If analog notations are converted to digital text for searching, then searchability is improved, but data loss and decipherability issues occur
Solution Approach 1:
The patent creates a digital copy of the analog notation's physical characteristics (stroke sequence, pressure, timing) without converting the content to digital text. This copy preserves the original analog data's essential features while enabling computational search operations on the structural properties rather than semantic content.
Solution Approach 2:
The patent transforms the analog notation into a different parameter space - instead of searching semantic text content, the system searches physical parameters like stroke sequence, pressure patterns, and temporal characteristics. This parameter transformation enables searchability while preserving the original analog data integrity.
2Reliability
If analog data is stored without digitization, then original information is preserved, but searching and retrieval become difficult
Solution Approach 1:
The patent introduces an intermediary representation that bridges analog storage and digital search - a digital model of physical characteristics that acts as a mediator between the preserved analog data and search operations. This intermediary enables retrieval without direct digitization of the content.
Solution Approach 2:
The patent replaces manual mechanical searching (physically flipping through pages or notes) with automated computational search based on captured physical parameters. The system substitutes human effort with algorithmic processing of stroke sequences, pressure patterns, and timing data.
3Productivity
If traditional digital text search is used for analog notations, then search efficiency is improved, but the unique characteristics of analog data are lost
Solution Approach 1:
The patent moves the search problem from the semantic text dimension to the physical characteristic dimension. Instead of searching for keywords in converted text, the system searches along dimensions of stroke sequence, pressure, and timing - adding a new dimensional approach to analog data search that preserves original characteristics.

AI summary
Systems and methods are provided for searching for analog data, including hand writing, facial expressions and voice data. With respect to analog writing, a device records and stores analog writing, including time, pressure and position as a writing tool moves on a touch screen device. A search term that includes time, pressure and position data, is received. The search term is compared with the time, pressure and position stored on the device. If they are similar, then the stored analog writing is displayed. In other example embodiments, facial expressions and voice data can be used as search terms to respectively search for stored facial expressions and voice data.
