Cross-Device Drag-and-Drop Interface for Seamless Call Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication systems lack a user-friendly method for transferring ongoing operations, such as in-progress calls, between devices, especially across different platforms, requiring cumbersome button presses and disrupting communication.
Innovation Solution
Implementing a drag-and-drop interface synchronization between adjacent devices, allowing users to transfer operations by dragging representations across device borders, utilizing communication pathways like Bluetooth, wireless, or IR, to maintain a consistent touch-screen interface experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional button-press methods are used for transferring calls between devices, then the operation can be completed, but the process is cumbersome and disrupts communication
Solution Approach 1:
The patent replaces the mechanical button-pressing system with a touch-based drag-and-drop interface. Users can visually drag a call representation from one device to another and release to transfer, substituting multiple discrete button presses with a continuous intuitive gesture that maintains communication throughout the transfer process.
2Ease of operation
If drag-and-drop interface is implemented across device borders, then user-friendliness is improved, but device synchronization complexity increases
Solution Approach 1:
The patent introduces a border region as an intermediary zone between two devices. This border acts as a mediator that receives drag operations from the first device and facilitates drop operations on the second device, managing the synchronization complexity by providing a standardized interface layer that abstracts the underlying communication protocols and device-specific implementations.
3Adaptability or versatility
If multiple communication pathways are supported for cross-platform operations, then adaptability is improved, but system complexity increases
Solution Approach 1:
The patent implements a universal drag-and-drop interface that functions across multiple communication pathways including Bluetooth, wireless networks, and infrared connections. The same user interaction model (drag across border, release to transfer) works regardless of the underlying communication technology, allowing the system to support multiple platforms and connection types through a single unified interface paradigm.

AI summary
A user interface(s) in which the displays of different devices become “synchronized” when the devices are brought into close proximity with one another. One exemplary embodiment permits drag-and-drop procedures that originate on one device to be terminated on the other. Illustratively, the solution could be handled in the following manner:The user would place the second device alongside or in close proximity to the first device,The two devices would detect each other,The user would touch the representation (such as an icon) of the party on the second device's display that they wish to add to the call,The user would slide the representation across the first device/second device border onto the first device's screen,The user would slide the representation to a spotlight or hot spot and then lift the finger from the screen,The party would be connected to the call.
