Interactive White Board Image Auto-Storage via SDN Controller
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional systems fail to reliably store images written on an image display apparatus without requiring frequent and troublesome user intervention, leading to potential loss of data when the power is switched off.
Innovation Solution
An information processing system comprising an Interactive White Board (IWB), a Software Defined Network (SDN) controller, and a smartphone, where the SDN controller automatically stores image data in a shared file server when a predetermined condition is met, such as a lack of user storage request within a set time period, ensuring images are saved even after the IWB's power is turned off.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the user manually stores images on the image display apparatus, then the images can be saved, but the operation becomes troublesome and time-consuming
Solution Approach 1:
The image display apparatus automatically detects when an image is displayed and initiates storage to a shared storage destination without requiring user intervention. The system monitors display state changes and autonomously completes the storage process, making the system serve itself rather than requiring manual user operations.
Solution Approach 2:
The system performs preliminary detection of display state changes and prepares storage actions before the user would need to manually intervene. By monitoring the display state in advance and automatically triggering storage when conditions are met, the system ensures images are saved before potential power loss or other disruptions.
2Productivity
If the image display apparatus stores images locally, then storage is quick, but data is lost when power is switched off
Solution Approach 1:
A shared storage destination acts as an intermediary between the image display apparatus and the final storage location. The apparatus quickly transfers images to this intermediate shared storage, which then maintains the data persistently. This intermediary layer enables both fast initial transfer and reliable long-term retention independent of the display apparatus power state.
Solution Approach 2:
The system transitions from single-device local storage to a distributed storage architecture involving multiple components (image display apparatus, shared storage destination, and potentially external storage). This dimensional shift from localized to distributed storage enables both speed and reliability requirements to be met simultaneously.
3Reliability
If frequent manual storage is required, then data loss is prevented, but user burden increases
Solution Approach 1:
The system implements automatic feedback loops where the display apparatus continuously monitors its own display state and automatically triggers storage operations when images are detected. This closed-loop feedback mechanism ensures data safety without requiring user awareness or intervention, eliminating the time users would otherwise spend on manual storage operations.
4Ease of operation
If the system automatically stores images, then user burden is reduced, but system complexity increases
Solution Approach 1:
The shared storage destination serves multiple functions: it acts as a buffer for rapid image transfer, a persistent storage medium for data retention, and a communication bridge between the display apparatus and external systems. This multi-functionality reduces the need for separate dedicated components, thereby limiting the increase in overall system complexity while achieving automatic storage.

AI summary
An information processing apparatus includes processing circuitry; and a memory storing computer-executable instructions that cause the processing circuitry to transmit an image acquisition request to an image display apparatus upon detecting that a predetermined condition is satisfied; receive image data of an image displayed on the image display apparatus, transmitted from the image display apparatus in response to the image acquisition request; and store the received image data in a shared storage destination.
