VNC Server Barcode Transmission for Remote Manual Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users cannot smoothly access user manual pages via two-dimensional barcodes when remotely controlling an image forming apparatus using VNC, as they cannot read the displayed barcodes with the camera of the operating VNC client.
Innovation Solution
An information processing apparatus with a transmitting unit that sends information related to the operation screen to a terminal when a predetermined key is pressed, allowing the terminal to display a two-dimensional barcode that can be read by a mobile terminal's camera.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a two-dimensional barcode is displayed on the VNC client terminal screen, then the user can see the barcode, but the user cannot read the barcode with the terminal's camera to access the user manual page
Solution Approach 1:
The patent introduces an intermediary mechanism where the VNC server captures the barcode image from its own display and transmits it to the VNC client terminal as an image file. This intermediary approach allows the barcode to be transferred in a format that the terminal camera can process, resolving the contradiction between displaying the barcode and enabling its readable transmission.
2Adaptability or versatility
If the VNC client terminal displays the operation screen locally, then the user can remotely control the apparatus, but the user cannot smoothly access user manual pages via two-dimensional barcodes
Solution Approach 1:
The patent merges the barcode display function with the VNC remote operation system by integrating the barcode image transmission into the existing VNC communication protocol. This combination ensures that the barcode functionality works seamlessly within the remote operation context, maintaining both remote control capability and reliable user manual access.
3Ease of operation
If a two-dimensional barcode display key is provided on the VNC client, then the user can trigger barcode display, but the user cannot read the displayed barcode to access information
Solution Approach 1:
The patent replaces the mechanical approach of directly displaying a readable barcode on the terminal screen with an electronic image transmission system. Instead of relying on the terminal's camera to read a displayed barcode, the system electronically transmits the barcode image from the VNC server to the client, substituting the optical reading mechanism with a digital image transfer mechanism.

AI summary
An information processing apparatus, that includes an operation unit having an operation screen and can be operated from a terminal connected via a network, comprises a transmitting unit for transmitting information related to the operation screen being displayed to the terminal in a case where it is decided that there is a predetermined instruction of a user to the operation unit.
