Proximity Sensor UI Adaptation for Mobile Display Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile devices lack dynamic adjustment of user interface content based on user proximity, relying solely on turning the display on or off without changing the visual characteristics of the information presented.
Innovation Solution
A mobile device system that utilizes a proximity sensor to generate a proximity metric, allowing the user interface adjustment component to dynamically adjust the content or visual characteristics, such as font size, image size, and lighting, based on the user's distance from the device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the display is turned on or off based on proximity, then power consumption is reduced, but the user interface remains static and lacks adaptability
Solution Approach 1:
The patent applies dynamics by transitioning from a static display state (on/off) to a dynamic state where the user interface continuously adapts its visual characteristics (font size, image size, spacing) based on real-time proximity measurements. This allows the interface to be responsive and adaptive without requiring the display to be fully on or off at all times, resolving the contradiction between power savings and adaptability.
Solution Approach 2:
The patent changes physical parameters of the user interface (font size, image size, line spacing, margins) based on proximity metric values. As the user moves closer or farther from the device, these parameters are adjusted dynamically, enabling the interface to adapt to different viewing distances while maintaining energy efficiency through selective rather than complete display activation.
2Illumination intensity
If the display content is made larger to improve visibility at a distance, then visibility is improved, but the amount of information that can be displayed decreases
Solution Approach 1:
The patent dynamically adjusts the size of display elements based on the user's proximity to the device. When the user is far away, larger fonts and images are used to maintain visibility. When the user moves closer, the elements are reduced in size to maximize information density. This dynamic adjustment resolves the contradiction by making the interface adaptable to the user's position rather than fixed at one size.
Solution Approach 2:
The system changes multiple display parameters simultaneously (font size, image size, line spacing, margins) based on proximity metrics. This coordinated parameter adjustment allows the interface to optimize both visibility and information density according to the user's viewing distance, preventing information loss while maintaining readability.
3Measurement precision
If manual adjustment of display settings is required, then precision of display characteristics can be controlled, but ease of operation is reduced
Solution Approach 1:
The patent implements self-service by enabling the user interface to automatically adjust its own visual characteristics based on proximity sensor data. The system monitors user position and autonomously modifies font sizes, image sizes, and spacing without requiring manual user intervention. This resolves the contradiction by providing precise, context-aware display adjustments while maintaining ease of operation through automation.
Solution Approach 2:
The system uses feedback from proximity sensors to continuously monitor user position and automatically adjust display parameters in response. This closed-loop feedback mechanism ensures that display characteristics remain optimized for the current viewing distance without requiring manual user adjustment, combining precision with ease of use.

AI summary
A proximity metric is obtained that indicates a proximity of a user's face relative to a mobile device. The content, or a visual characteristic of information, on a user interface of the mobile device is adjusted, based upon the proximity metric.
