Ultra-Wideband Distance Detection for Dynamic User Interface Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable electronic devices with content redirection features face challenges in user interface settings that are static and difficult to adjust, leading to user frustration due to limitations in mouse pointer size, speed, display resolution, and audio control, especially when used at varying distances from the content presentation companion device.
Innovation Solution
The system dynamically enhances user interface and audio performance characteristics of a content presentation companion device based on the distance between the electronic device and the companion device using ultra-wideband technology for precise distance measurement and angle of arrival, adjusting features such as mouse pointer size, speed, display resolution, and audio lag.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If content redirection is used to stream content to a larger display, then content visibility is improved, but user interface settings become static and difficult to adjust
Solution Approach 1:
The patent implements dynamic user interface settings that automatically adjust based on the detected distance between the portable electronic device and the content presentation companion device. Mouse pointer size, speed, display resolution, and audio control parameters are dynamically modified in real-time as the user moves closer or farther away, eliminating the need for manual adjustments and making the interface adaptive to usage scenarios.
Solution Approach 2:
The system employs distance detection technology to continuously monitor the spatial relationship between the portable device and companion device. This distance information serves as feedback that automatically triggers corresponding UI parameter adjustments, creating a closed-loop system where the interface responds to user position without requiring explicit user input for each adjustment.
2Illumination intensity
If mouse pointer size is increased for better visibility at distance, then visibility is improved, but precision control deteriorates
Solution Approach 1:
The patent dynamically adjusts mouse pointer size based on the detected distance between devices. When the portable device is farther from the companion device, the pointer size increases for better visibility. When moved closer, the pointer size decreases to restore precision control. This dynamic sizing resolves the contradiction by adapting pointer dimensions to the actual usage context.
Solution Approach 2:
The system changes multiple UI parameters simultaneously based on distance, including pointer size, pointer speed, and display resolution. By coordinating these parameter changes, the system maintains both visibility and precision - larger pointers at distance are compensated by adjusted speeds and resolutions to preserve control accuracy.
3Device complexity
If UI settings are made static for simplicity, then device complexity is reduced, but adaptability to different usage scenarios deteriorates
Solution Approach 1:
The system provides self-service by automatically detecting user distance and adjusting UI parameters without requiring manual configuration. The distance detection mechanism and parameter adjustment logic operate autonomously, adapting the interface to different usage scenarios based on spatial context alone, thus maintaining simplicity while achieving high adaptability.
Solution Approach 2:
The distance-based adjustment mechanism serves multiple UI parameters simultaneously (pointer size, speed, resolution, audio control), creating a universal adaptation system. A single distance detection function controls multiple aspects of the user interface, achieving versatile scenario adaptation without proportionally increasing system complexity.
