Adaptive Video Call Display for Mobile Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Video calls on mobile devices often result in user distraction and resource wastage due to high data and network requirements, particularly when driving, as existing solutions fail to effectively manage video quality based on device speed and resource availability.
Innovation Solution
A method that restricts video information displayed on a mobile device during video calls by limiting frame rates, display size, or resolution based on the device's speed, and prevents video display altogether at high speeds to prevent distraction and conserve resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If video calls are provided with high quality and full information, then user experience is improved, but device resources and network bandwidth are excessively consumed
Solution Approach 1:
The patent applies dynamics by making the video information display adaptive to device state. The system dynamically adjusts video quality parameters (resolution, frame rate, detail level) based on real-time detection of device speed and resource availability. When the device is stationary or moving slowly with sufficient resources, full-quality video is displayed. When the device is moving quickly or resources are constrained, the system automatically reduces video information delivery to conserve battery and network resources, thus resolving the contradiction between information quality and resource consumption.
2Ease of operation
If video calls are provided during driving, then communication convenience is improved, but user distraction and safety risks increase
Solution Approach 1:
The patent implements feedback by continuously monitoring device speed (via GPS or accelerometer) and using this information to control video display. When the device detects that the user is driving at high speed, the system automatically reduces or disables video information display to minimize distraction. This feedback loop allows the system to adapt video delivery to driving conditions, maintaining communication convenience while reducing safety risks. The hands-free capability combined with speed-based video suppression creates a safe driving mode that preserves communication functionality without excessive visual distraction.
3Adaptability or versatility
If video calls are provided at high device speeds, then communication availability is improved, but video quality and user experience deteriorate due to motion blur and distraction
Solution Approach 1:
The system dynamically adapts video delivery based on device speed detection. When the device is moving at high speed, the patent automatically reduces video information transmission and display to account for motion blur and user distraction. The system adjusts video parameters such as resolution, frame rate, and information density according to the detected speed threshold. This dynamic adaptation maintains communication availability (the call continues) while appropriately reducing video quality expectations to match the mobile viewing conditions, thus resolving the contradiction between availability and quality.
