Display Apparatus Metadata for Handwritten-Origin Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display apparatuses struggle to identify handwritten data accurately, particularly when using black-and-white supporting devices like electronic paper, which cannot display colors and convert color information into black-and-white density, leading to difficulty in distinguishing between different colors.
Innovation Solution
A display apparatus that associates handwritten data with color information and meta-data, enabling it to display handwritten input originated data with black-and-white highlighting based on the associated color information, and transmit this data to various devices without losing the identification of its handwritten origin.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If black-and-white supporting apparatus converts color information into black-and-white density for display, then the apparatus can display color files, but handwritten data cannot be accurately identified
Solution Approach 1:
The patent segments the display system into two distinct data streams: one for color information conversion and another for handwritten data identification. By separating these functions, the system can convert color files for black-and-white display while simultaneously preserving handwritten data markers for accurate identification, resolving the contradiction between versatility and precision.
Solution Approach 2:
The patent introduces an intermediary mechanism (handwritten data identification information) that mediates between the color conversion process and the display output. This intermediary layer ensures that even when color information is converted to black-and-white density, the handwritten origin of the data is preserved and can be accurately identified through the embedded identification markers.
2Adaptability or versatility
If color information is converted into black-and-white density, then black-and-white apparatus can display color files, but distinction between different colors is lost
Solution Approach 1:
The patent applies preliminary action by embedding handwritten data identification information into the data stream before the color-to-black-and-white conversion process occurs. This ensures that color distinction information is preserved in the identification layer, allowing black-and-white apparatus to display color files while maintaining the ability to distinguish handwritten data through its unique markers.
Solution Approach 2:
The patent creates a copy of the essential identification features in a separate data layer that is independent of the color information. This copying mechanism ensures that the handwritten data markers are replicated and preserved even when the original color information is converted to black-and-white density, preventing loss of critical identification information.
3Device complexity
If handwritten data is displayed without associated identification information, then display is simpler, but handwritten data cannot be identified as originating from a particular display apparatus
Solution Approach 1:
The patent implements self-service by having the display apparatus automatically embed its own identification information into the handwritten data it generates. This self-service mechanism allows the apparatus to tag its own output with unique identifiers, enabling reliable identification of handwritten origin without requiring external verification systems, thus maintaining simplicity while improving reliability.
Data Source
AI summary
An object is to provide a display apparatus capable of identifying handwritten data drawn by a particular display apparatus. A display apparatus for displaying data, in which indication of handwritten input originated data drawn by the display apparatus is recorded in association with the handwritten data.
