Projection Display Interface Synchronization for Gaze Transfer Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display systems require users to frequently switch their gaze between an adjusting screen and the projection image, leading to a heavy burden on the user during image adjustment.
Innovation Solution
A method and system where a projection device displays a first user interface for adjusting a projection image, and a control device displays a second user interface with a display object corresponding to the projection image, allowing for simultaneous adjustment and updating of both interfaces to reduce user burden.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the control device displays an adjusting screen for projection image adjustment, then the user can perform adjustment operations, but the user must frequently transfer gaze between the adjusting screen and the projection image, increasing user burden
Solution Approach 1:
The patent merges the adjusting screen display with the projection image display by superimposing the user interface on the projection image itself. This allows the user to perform adjustment operations and view the projection image simultaneously in the same visual field, eliminating the need to transfer gaze between separate displays and thereby reducing the time loss from frequent gaze transfers.
2Ease of operation
If the projection device displays a user interface for adjustment, then the user can adjust the projection image, but the projection device cannot display the projection image clearly during adjustment
Solution Approach 1:
The patent applies local quality by making the user interface semi-transparent or positioning it in specific regions that do not significantly interfere with the projection image display. The interface elements are rendered with reduced opacity or placed in peripheral areas, allowing the projection image to remain clearly visible while still providing accessible adjustment controls.

AI summary
A display control method includes displaying, by a projection device, a first user interface related to an adjustment of a projection image, displaying, by a control device communicating with the projection device, a second user interface including a display object corresponding to the projection image, transmitting, by the projection device, first adjustment information based on a first operation to the first user interface to the control device when the projection device accepts the first operation, adjusting, by the projection device, the projection image based on the first adjustment information, updating, by the control device, the display object based on the first adjustment information, transmitting, by the control device, second adjustment information based on a second operation to the second user interface to the projection device when the control device accepts the second operation, adjusting, by the projection device, the projection image based on the second adjustment information, and updating, by the projection device, the first user interface based on the second adjustment information.
