Wearable Display Terminal for Printed Link Destination Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face inconvenience when trying to locate linked information in printed matter, as they need to manually turn pages to find the link destination, which is time-consuming and inefficient.
Innovation Solution
An information display system that includes a printing apparatus and a wearable display terminal, which transmits and displays link destination information, allowing users to visually recognize the information without physically turning pages, using a visual recognition determination unit, image-data extraction unit, link status determination unit, and display control unit to extract and display the link destination information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If users manually turn pages to locate link destination information, then they can find the information, but it is time-consuming and reduces browsing efficiency
Solution Approach 1:
The patent introduces a wearable device as an intermediary between the printed matter and the user's vision. The wearable device captures images of the printed matter, processes the image data to identify link destination information, and displays it to the user. This intermediary system eliminates the need for manual page turning while maintaining ease of information access.
Solution Approach 2:
The patent replaces the mechanical action of manually turning pages with an automated optical and electronic system. The wearable device uses image capture, processing, and display technologies to substitute the physical manipulation of printed matter, thereby reducing time loss while preserving ease of operation.
2Productivity
If link destination information is displayed on the same page as the link source, then information access is immediate, but this requires modifying the printing process and increases device complexity
Solution Approach 1:
The wearable device performs multiple functions: capturing images of printed matter, processing image data to identify link information, determining link destinations, and displaying results. This multi-functional approach increases productivity without requiring separate dedicated devices for each function, thereby managing complexity through integration.
Solution Approach 2:
The system creates a digital copy of the printed matter through image capture, processes this copy to extract link destination information, and displays the extracted information. This copying approach enables efficient information access without modifying the original printing process or physical printed matter, thus avoiding increased device complexity on the printing side.
Data Source
AI summary
The information display system includes a printing apparatus and a display terminal. The display terminal's control unit includes a visual recognition determination unit, an image-data extraction unit, a link status determination unit, a link destination information acquisition unit, and a display control unit. The link status determination unit determines whether a page of printed matter visually recognized by a user through lenses contains a representation associated with link destination information. If the link status determination unit determines the presence of the representation associated with the link destination information, the link destination information acquisition unit acquires the link destination information based on the image data extracted by the image-data extraction unit. The display control unit performs control operations to display on the lenses the link destination information acquired by the link destination information acquisition unit so that the user can visually recognize the link destination information.
