PC–Phone Object Transfer With Shared Input Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In collaborative office scenarios between multiple terminals, such as a PC and a mobile phone, the projection of the mobile phone's interface to the PC occupies display space, rendering the mobile phone's hardware capabilities, like touchscreen and stylus, ineffective, and reducing overall usage efficiency.
Innovation Solution
A cross-device object drag method that allows users to shuttle objects between terminals using an input device without projection, enabling all terminals' hardware capabilities to participate in collaborative work, using keyboard and mouse sharing technology to transfer objects like texts or files.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the mobile phone interface is projected to the PC display for multi-screen collaboration, then content drag function is enabled, but display space of the PC display is occupied and mobile phone hardware capabilities cannot participate
Solution Approach 1:
The patent extracts the content drag function from the projection scenario, allowing it to operate independently without requiring the mobile phone interface to be projected to the PC display. This enables content transfer while preserving display space on both devices.
Solution Approach 2:
The patent enables the input device to serve multiple functions: it can control the PC when the pointer is on the PC display, and control the mobile phone when the pointer is on the mobile phone display, allowing both devices to participate actively in collaborative operations without projection.
2Ease of operation
If the mobile phone interface is projected to the PC display, then content drag is enabled, but hardware capabilities like touchscreen and stylus of the mobile phone cannot participate
Solution Approach 1:
The patent makes the system universal by enabling multiple input methods (mouse, touchscreen, stylus) to work across both PC and mobile phone platforms. The mobile phone's touchscreen and stylus can directly interact with content on both displays, allowing hardware capabilities to participate fully in collaborative tasks.
Solution Approach 2:
The patent introduces a mediator mechanism where the mobile phone display acts as an additional interaction surface. When content is dragged from the PC display to the mobile phone display, the mobile phone's hardware capabilities (touchscreen, stylus) can continue to manipulate the content on its own display, enabling full hardware participation.
3Productivity
If projection is started to enable content drag between terminals, then object transfer is possible, but display space is occupied reducing usage efficiency
Solution Approach 1:
The patent extracts the content transfer functionality from the projection dependency, allowing objects to be dragged and transferred between terminals without requiring the mobile phone interface to be projected to the PC. This maintains productivity while preserving display space on both devices.
Solution Approach 2:
The patent adds a new dimension to the interaction model by enabling the mobile phone display to serve as both a source and destination for dragged content. Objects can be dragged from the PC display to the mobile phone display and manipulated there, creating an additional workspace dimension without occupying display space through projection.

AI summary
A second terminal displays, on a display of the second terminal, an object dragged from a first terminal; the second terminal displays a second cursor on the object; the second terminal receives data of a motion operation that is input by a user by using an input device of the first terminal; and the second terminal displays, on the display of the second terminal based on the motion operation, an animation in which the object moves with the second cursor.
