Display Compensation for User and Device Movement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable computing devices face challenges in user experience due to movement relative to the user, making it difficult to follow displayed content, as existing solutions do not effectively compensate for user and device movement.
Innovation Solution
A system that determines the movement of both the device and the user, applying compensation to the displayed content by shifting or zooming it to maintain visibility, while ensuring the content remains within the display boundaries, using modules for device and user movement determination, display compensation, and eye tracking to adjust the content accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If display content is shifted to compensate for device movement, then user readability is improved, but content may be positioned beyond display boundaries
Solution Approach 1:
The patent applies different compensation strategies to different portions of the display based on their proximity to edges. Content in central regions receives full compensation adjustment, while content near edges undergoes restricted adjustment to prevent positioning beyond display boundaries. This local differentiation resolves the contradiction by optimizing readability where possible while maintaining content within visible areas.
Solution Approach 2:
The compensation amount is dynamically adjusted based on real-time calculation of device movement, user eye position, and content location. The system continuously modifies the compensation magnitude, applying full compensation when safe and reducing it when content approaches display boundaries, thereby adaptively resolving the contradiction between readability improvement and content positioning.
2Ease of operation
If compensation is applied to all content, then user experience during movement is improved, but content near display edges may be lost
Solution Approach 1:
The system evaluates each content element's position relative to display boundaries and applies compensation selectively. Content in safe zones receives full compensation to maintain readability during movement, while content in vulnerable edge zones receives restricted compensation to prevent it from moving beyond display boundaries and becoming invisible.
Solution Approach 2:
Instead of applying uniform full compensation to all content, the system applies partial compensation only where necessary to prevent content loss. This partial action approach maintains user experience for most content while avoiding the excessive compensation that would cause edge content to disappear.
3Measurement precision
If eye tracking is used to detect user gaze position, then compensation accuracy is improved, but system complexity increases
Solution Approach 1:
The patent introduces an eye tracking module as an intermediary component that bridges the gap between device movement sensors and the display compensation system. This dedicated intermediary captures user gaze information and translates it into compensation parameters, improving measurement precision while containing complexity within a specialized module rather than distributing it throughout the entire system.

AI summary
A direction and distance of movement of a display device as well as of a user of the display device are determined. Based on these determined directions and distances of movement, compensation to apply to content displayed on the display device to compensate for movement of the user with respect to the device is determined and applied to the content. A portion of the display device at which the user is looking can also be detected. The compensation is applied to the content only if applying the compensation would not result in the portion being positioned beyond the display device. If applying the compensation would result in the portion being positioned beyond the display device then appropriate corrective action is taken, such as not applying the compensation to the content.
