Brightness Adjustment via Physical Button Gesture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic devices require users to quit applications and navigate through complex menus to adjust screen brightness, leading to low response speed and inefficient user interaction.
Innovation Solution
A method and apparatus that utilize a designated physical button, such as a volume adjustment button, to display a brightness adjustment panel on a touch-sensitive display, allowing users to adjust screen brightness through gesture operations while maintaining the ability to adjust volume, thereby simplifying the process and improving response speed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the screen brightness adjustment option is set in a secondary menu or pull-down menu, then the system can maintain a simple interface structure, but the user interaction process becomes complex and response speed decreases
Solution Approach 1:
The brightness adjustment function is extracted from the complex menu system and assigned to a dedicated physical button. This separation allows the main interface to remain simple while providing direct access to brightness adjustment through the physical button, eliminating the need to navigate through menus.
Solution Approach 2:
A physical button serves as an intermediary between the user and the brightness adjustment function. This intermediary provides a direct, tactile interface that bypasses the complex menu navigation, enabling users to quickly access and adjust brightness without interacting with the software menu system.
2Reliability
If the brightness adjustment requires quitting the current application to access system settings, then the system can maintain centralized control of brightness settings, but the user experience deteriorates due to application interruption and re-login requirements
Solution Approach 1:
The physical button is designed to serve multiple functions: it can trigger brightness adjustment, volume adjustment, or other system functions depending on the current context. This multi-functionality allows the button to provide quick access to system controls without requiring the user to leave the current application, as the system handles the adjustment within the running application context.
Solution Approach 2:
The system pre-configures the physical button to trigger brightness adjustment functionality before the user needs it. When the user presses the button, the system is already prepared to handle the adjustment request, displaying the brightness panel immediately without requiring application termination or re-login, thus maintaining both system control and user experience.
3Productivity
If a designated physical button is used to access the brightness adjustment panel directly, then the response speed and efficiency improve, but the device requires an additional physical button or repurposes an existing one
Solution Approach 1:
The invention repurposes an existing physical button (such as the volume button) to also trigger brightness adjustment. This approach avoids adding new physical components while providing direct access to brightness control, thereby improving adjustment efficiency without increasing device physical complexity.
Solution Approach 2:
The brightness adjustment function is merged with the existing physical button functionality. The button serves dual purposes: its original function (e.g., volume control) and the new brightness adjustment function. This merging eliminates the need for additional physical buttons while maintaining quick access to brightness settings.
