Multi-Screen Interface Control via Virtual Object Projection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Multi-screen terminal devices face inconvenience when controlling objects across different screens, requiring frequent switching between screens for touch operations.
Innovation Solution
A method and device that allows a user's input on a target manipulation control in one screen to execute actions on objects in another screen, enabling direct control and interaction between screens by projecting the display interface of the second screen onto the first screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a user operates objects on different screens separately, then each screen can display its own interface independently, but the user must frequently switch between screens which reduces operational convenience
Solution Approach 1:
The patent creates a virtual copy of the second screen's interface elements (icons, widgets) and displays them within a manipulation control area on the first screen. This virtual copy allows users to interact with second screen objects directly from the first screen without physical switching, effectively resolving the time loss and operational inconvenience caused by frequent screen switching.
Solution Approach 2:
The manipulation control area acts as an intermediary interface between the first screen and second screen. It provides a bridge that enables users to control objects on the second screen through the first screen's interface, eliminating the need for direct screen switching while maintaining independent screen functionality.
2Productivity
If the system allows cross-screen object control, then operational efficiency improves, but the interface complexity increases due to multiple screen interactions
Solution Approach 1:
The patent segments the cross-screen control functionality into distinct components: the manipulation control area on the first screen, the virtual copy of second screen elements, and the underlying screen switching mechanism. This segmentation allows the complex cross-screen control to be managed through simple, localized interactions without overwhelming the user with system complexity.
Solution Approach 2:
The manipulation control area serves multiple functions: it displays virtual copies of second screen objects, accepts user inputs for those objects, and coordinates screen switching operations. This multi-functionality consolidates what would otherwise require separate complex interfaces into a single unified control mechanism, improving productivity without proportionally increasing perceived complexity.

AI summary
The embodiments of the present disclosure provide an object control method and a terminal device. The method includes: receiving a user's first input on a target manipulation control and a first object in a first screen, where an object in the target manipulation control is an object in a second screen, and the second screen is a screen, among at least two screens, other than the first screen; and executing, on the first screen and in response to the first input, a first action corresponding to the first input on the first object, where the first object is an object in the target manipulation control or an object in a target area, and the target area is an area on the first screen other than an area where the target manipulation control is located. The method may be applied to an object control scenario of a multi-screen terminal device.
