Mobile Device Display Adjustment for Low-Disruption Video Recording
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The brightness of mobile electronic device displays during video recording in darkened venues causes distractions to others, and existing technologies do not adequately address this issue while allowing users to adjust settings for desired recordings.
Innovation Solution
A mobile electronic device equipped with an accelerometer or gyroscope to detect when it is being raised in a predetermined manner, automatically adjusting display brightness, color, and audio settings to minimize disruptions, such as dimming, changing to red light, or silencing, during video recording.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the display brightness is kept high for clear viewing and settings adjustment, then the user can easily adjust phone settings, but it causes distraction to other people in the vicinity
Solution Approach 1:
The display brightness is made dynamic rather than static. The system automatically adjusts brightness based on detected device orientation and usage context. When the device is held horizontally or at angles typical of recording activities, brightness is reduced automatically, while maintaining user control when held vertically for normal viewing.
Solution Approach 2:
The system implements feedback loops where sensors continuously monitor device orientation, position, and usage patterns. This feedback is processed to automatically adjust display characteristics, creating a closed-loop system that adapts to user behavior and environmental context without manual intervention.
2Object-affected harmful factors
If the display brightness is reduced to minimize distraction, then distraction to others is reduced, but the user's ability to view and adjust settings is compromised
Solution Approach 1:
Different display characteristics are applied based on local context - specifically device orientation and usage mode. When held vertically for normal viewing, full brightness and color are maintained. When held horizontally or at recording angles, brightness is reduced and color may shift to red, creating localized quality adjustments based on spatial context.
Solution Approach 2:
The system changes display parameters (brightness level, color temperature, hue) based on detected conditions. Brightness can be reduced from maximum to lower levels, and color can shift from full spectrum to red-dominated display, allowing the same hardware to provide different visual characteristics for different usage scenarios.
3Object-affected harmful factors
If automatic brightness adjustment is implemented to reduce distraction, then distraction to others is minimized, but device complexity increases
Solution Approach 1:
Existing sensors (accelerometers, gyroscopes, proximity sensors) are repurposed for dual functions - their primary functions plus automatic brightness control. The camera itself can detect scene brightness and user viewing conditions, adding this capability without requiring dedicated hardware, thus reducing overall system complexity.
Solution Approach 2:
The device automatically adjusts its own display characteristics based on self-monitoring of orientation, position, and environmental conditions. No external control or complex user interaction is needed - the system serves itself by detecting when brightness adjustment is appropriate and executing the adjustment autonomously.

AI summary
An apparatus and method for automatically adjusting of one or more operating characteristics of a mobile electronic device. When a mobile electronic device is recording video, a user interface of the mobile electronic device is automatically adjusted in response to determining that the mobile electronic device has been physically manipulated in one or more particular ways. For example, a touch screen may be dimmed while the mobile electronic device is recording video and the mobile electronic device determines that it has been raised above a user's head.
