Translucent Overlay for Crash State Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional computer systems that crash often lose critical user data and fail to provide clear information about the crash state, as they either clear the screen, display uninformative dialog boxes, or become locked, making it difficult for users to understand the system's status.
Innovation Solution
A visual method that darkens the entire monitor screen by reducing pixel brightness and overlays a translucent red film, allowing the original content to remain visible while conveying the crash state through color and shape, enabling users to view critical data alongside informative messages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the screen is cleared and replaced with a useful message, then the user is informed about the crash state, but the original screen content and critical data are lost
Solution Approach 1:
The patent merges two previously separate functions into one visual state: displaying the crash message and preserving the original screen content simultaneously. By overlaying the translucent film with crash information onto the existing screen content, the system combines information delivery and data preservation in a single visual layer, eliminating the need to choose between clearing the screen or maintaining it.
Solution Approach 2:
The patent adds a new visual dimension by introducing a translucent overlay layer that sits above the original screen content. This dimensional addition allows crash information to be displayed in the foreground while the original content remains visible in the background, creating a layered visual hierarchy that conveys multiple pieces of information simultaneously without conflict.
2Loss of information
If a pop up dialog box is displayed concerning the crash, then the user receives information about the crash, but the system may not be able to properly generate or display new windows and the original screen content is lost
Solution Approach 1:
The patent applies preliminary action by modifying the existing screen content in place rather than attempting to create new display elements after the crash. By directly altering the pixel values of the current framebuffer to add the translucent overlay, the system avoids the unreliable post-crash window generation process and ensures the crash message is displayed using the already-established rendering context.
3Reliability
If the system resets or maintains a locked state, then the system stabilizes, but the user is not sure what just happened and no further useful information is conveyed
Solution Approach 1:
The translucent overlay acts as an intermediary that bridges the gap between the crash event and user understanding. It provides immediate visual feedback about the system state without requiring the user to interpret locked screens or reset behaviors, translating technical crash states into comprehensible visual information that maintains system stability while informing the user.

AI summary
Disclosed is a visual method of communicating an abnormal situation (e.g., the crashed or downed state) of the computer system including a display. The system status is thus indicated to the user. Upon a system crash or downed state, the display entirely or in part (a first area) is proportionally decreased in brightness. Brightness of a second area (which may overlap the first area) is increased in full or in part by a fixed amount. This results in a translucent film overlay which preserves in the background the display screen content existing at the moment the system crashed. The translucent film overlay may have predefined characteristics, such as tint to signify system status and/or level or degree of the system's problem.
