Content Display Support System for Unregistered Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing content display systems for remote sites face difficulties in allowing public participants to access shared materials during meetings or seminars without prior registration, making it hard for them to obtain and view shared content.
Innovation Solution
A content display support system that includes a portable terminal, a content display support device, and a shooting device, where the shooting device transmits shot images and positional information to the content display support device, which generates combination content by embedding positional information into the images and transmits supplementary information to the portable terminal upon request, enabling easy display of content with embedded positional data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a shared server stores document data and provides it through authentication process, then document security is improved, but access complexity increases for public participants
Solution Approach 1:
The patent introduces an image forming apparatus as an intermediary device that captures images of displayed documents and transmits them to portable terminals. This mediator enables public participants to access document content without needing authentication credentials, as the system captures and redistributes visual representations of the documents rather than requiring direct server access
Solution Approach 2:
The system creates visual copies of document content by capturing images with the image forming apparatus. These image copies are then transmitted to portable terminals, allowing participants to view and interact with document content without accessing the original secured server, thus bypassing authentication requirements while maintaining content accessibility
2Measurement precision
If positional information is embedded in shot images, then content delivery accuracy is improved, but processing complexity increases
Solution Approach 1:
The image forming apparatus performs preliminary capture of documents at specific display positions before transmission. The positional information is extracted and embedded in advance during the image capture process, so that when images are received at portable terminals, the position data is already prepared and integrated, reducing processing burden at the receiving end
Solution Approach 2:
The patent merges the document image capture function with positional information extraction and embedding in a single integrated process at the image forming apparatus. This combination eliminates the need for separate processing steps at receiving devices, as the position data is already integrated with the image content when it reaches the portable terminal

AI summary
When an image of content reproduced by a first reproduction device is shot, a content display support device obtains the shot image and positional information that specifies the position and orientation of a shooting device. The content display support device generates combination content by visualizing and embedding the positional information in the shot image and transmits the combination content to a second reproduction device. A portable terminal obtains the positional information from an image obtained by shooting the combination content reproduced by the second reproduction device. The portable terminal requests supplementary information by transmitting the positional information to the content display support device. The supplementary information associated with the positional information is transmitted from the content display support device to the portable terminal and displayed at the portable terminal.
