Adaptive Display Magnification and Audio Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile communication devices struggle to adaptively maintain user-preferred audio and visual interfaces due to changing user orientation and distance, as well as environmental conditions, leading to compromised audio and visual output quality.
Innovation Solution
A system that dynamically adjusts audio and visual attributes using sensors to maintain user-preferred settings, incorporating controllers for audio and visual content, and imager-based detection for adaptive audio filtering and directional steering, allowing for real-time adjustments based on user-device relative positions and environmental changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the device output (visual/audio) is fixed, then the device structure is simple, but the user interface quality deteriorates when user distance or orientation changes
Solution Approach 1:
The patent implements dynamic adjustment of display magnification and audio output based on real-time detection of user distance and orientation. The display controller adjusts font sizes and visual scaling factors dynamically, while the audio controller modifies volume and spatial audio characteristics based on sensor data, transforming static output into adaptive dynamic output that maintains quality regardless of user position
Solution Approach 2:
The system continuously monitors user distance via proximity sensors and orientation via motion sensors, then feeds this information back to the display and audio controllers. This closed-loop feedback mechanism enables real-time adaptation of visual and audio output parameters to maintain optimal user interface quality as user position changes
2Ease of operation
If the device adapts to user position changes, then the user interface quality is maintained, but the power consumption increases
Solution Approach 1:
Instead of continuous adjustment, the system uses periodic sampling of sensor data at defined intervals (e.g., when significant position changes are detected). The display and audio parameters are updated only when threshold changes in user distance or orientation are exceeded, reducing unnecessary processing and power consumption while maintaining adaptive functionality
Solution Approach 2:
The system adjusts discrete parameter levels (display magnification tiers, audio volume steps) based on detected user position ranges, rather than continuous adjustment. This quantized approach reduces computational overhead and enables more efficient power management while preserving the adaptive user experience
3Adaptability or versatility
If sensors and controllers are added for adaptive output, then the user interface adapts to environment, but the device complexity increases
Solution Approach 1:
The patent leverages existing multi-functional sensors in mobile devices (proximity sensors originally for call detection, motion sensors for screen rotation) and extends their utility to control display magnification and audio output. By reusing existing sensor hardware for multiple functions, the system achieves environmental adaptation without adding dedicated sensors, thereby limiting the increase in device complexity

AI summary
Techniques and technologies are presented for adapting an attribute magnification for a mobile communication device (100). An output device for the attribute is connected to the mobile communication device (100). A sensor tracks (112) distance of a user's head in relation to the mobile communication device (100); while a controller (104) initiates a setting phase for magnification change and subsequently a tracking phase, opposite from the setting phase, for dynamically adjusting the attribute from the mobile communication device (100).
