Digital Signage Error Display Control via User Authentication

Solution Overview

Problem

Existing digital signage systems often fail to display contents due to setting errors or communication failures, leading to unnecessary error messages that confuse users and can go unnoticed if errors are not recognized.

Innovation Solution

An image processing apparatus that allows users to switch between displaying or hiding error messages when signage contents cannot be displayed, based on predetermined conditions and user authentication levels, enabling early error detection and prevention of user confusion.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If an error message is displayed when signage contents cannot be displayed, then error recognition is improved, but user confusion increases in environments where users cannot handle errors

Engineering Contradiction:

Improveerror recognitionVSAvoiduser confusion

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The system dynamically adjusts error message display based on user authentication levels. Different user groups (e.g., administrators vs. general users) receive different error notification behaviors, allowing the system to adapt to varying user capabilities and environments

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The error handling mechanism applies different qualities to different user groups. Specific user authentication levels trigger different error message display policies, providing tailored error notification behavior based on the user's role and capability

Inventive Principle:

Principle #3Local quality

2Object-affected harmful factors

If no error message is displayed when signage contents cannot be displayed, then user confusion is avoided, but error recognition is lost

Engineering Contradiction:

Improveuser confusionVSAvoiderror recognition

3Reliability

If error messages are displayed in all environments, then error recognition is improved, but ease of operation decreases in environments where users cannot handle errors

Engineering Contradiction:

Improveerror recognitionVSAvoiduser operation

Core Design Contradiction:
