Loop Display Content Transfer Control with Dynamic Friction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In environments with multiple connected displays, content transfer operations fail to stop promptly when display areas are arranged in a loop, causing the content to continue moving undesirably.
Innovation Solution
A system that uses a sphere geometry model to project displays onto a spherical surface, determining connection relationships and controlling content transfer based on these relationships to prevent continuous looping, employing a server apparatus and display control apparatuses that manage content creation, transfer, and dynamic friction coefficients to ensure content stops at intended destinations.

1Area of stationary object
If display areas are arranged in a loop configuration, then the display coverage and viewing area are improved, but the content transfer operation fails to stop promptly and continues moving undesirably
Solution Approach 1:
The patent applies spherical geometry to model the loop arrangement of multiple displays. By projecting display coordinates onto a spherical surface, the system can accurately determine spatial relationships and connection paths between displays in a loop configuration, enabling proper control of content transfer operations to stop at appropriate destinations without continuous movement.
2Ease of operation
If a predetermined dynamic friction coefficient is used for content transfer, then the content transfer operation is simple, but the content does not stop at the desired destination and may continue moving after returning to the original position
Solution Approach 1:
The patent dynamically adjusts the friction coefficient based on the content's position and movement state during transfer operations. Instead of using a fixed predetermined value, the system modifies the friction parameter in real-time to ensure the content stops at the intended destination, preventing overshooting and continuous movement in loop arrangements.
Solution Approach 2:
The system implements feedback control by continuously monitoring the content's position during transfer operations and adjusting the friction coefficient accordingly. This closed-loop control ensures that the content stops at the desired destination by comparing actual position with target position and modifying friction parameters to achieve precise stopping.
