Display Stain Detection and Marker Indication for Operability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Interactive display devices with blots or blemishes on the screen reduce operability and visibility, as users may struggle to accurately operate the device at stained areas, leading to a compromised user experience.
Innovation Solution
A display method and device that includes a stain detection system using a processor to identify stains on the input display part and display a marking at the stained area, allowing users to avoid or address the stains, thereby improving operability and user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a user operates the display device at positions with blots or blemishes, then the operation can be performed, but the user cannot get the original sensation of operating the display device
Solution Approach 1:
The system performs preliminary detection of stains on the display screen before user operation. By detecting stain positions in advance and displaying markers at these positions, the system prepares the information needed for users to make informed operational decisions, thereby preventing unexpected reductions in operability and maintaining original operating sensation.
Solution Approach 2:
The patent introduces an intermediary marker display that mediates between the stain condition and user operation. The marker serves as an intermediary information element that communicates the presence of stains to users without directly interfering with the touch panel's detection function, thus preserving operation accuracy while improving operating sensation.
2Illumination intensity
If stains are present on the display screen, then visibility is reduced, but the display device can still function
Solution Approach 1:
The system employs visual markers with distinct colors or brightness levels to indicate stain positions. These markers create color or luminance contrasts that draw user attention to affected areas, compensating for the visibility reduction caused by stains and maintaining overall operability through enhanced visual guidance.
