Gesture-Based Cross-Device Task Migration for Floating Windows
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cross-device task migration methods, such as Airplay and sidecar, are limited to specific scenarios and cannot be applied universally, failing to support multi-window display and floating window functionalities across various devices.
Innovation Solution
A cross-device task migration method utilizing pre-specified hand gestures to identify and migrate content between devices, including scaling down pages to floating windows, determining target devices through proximity and historical usage, and sending content via gestures, enabling cross-device task migration on any device in any scenario.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If Airplay protocol is used for wireless projection, then audio/video media tasks can be sent between devices, but the protocol cannot be applied in all scenarios and lacks universal functionality
Solution Approach 1:
The patent implements a universal cross-device task migration system that can handle multiple task types (audio/video playback, document editing, browsing, etc.) across different device categories (mobile phones, tablets, computers, smart TVs) through a single unified protocol, eliminating the need for scenario-specific protocols like Airplay
2Adaptability or versatility
If sidecar protocol is used for screen extension, then multi-window display can be achieved on specific devices, but the protocol cannot be applied in all scenarios
Solution Approach 1:
The patent creates a universal task migration framework that supports multiple display modes (multi-window, floating window, full-screen) across diverse device types through a single protocol, enabling multi-window functionality without being limited to specific device pairs
3Ease of operation
If manual device selection is required for projection, then connection can be established, but the operation becomes complex and time-consuming
Solution Approach 1:
The system automatically detects available devices in the vicinity, determines compatibility, and establishes connections without requiring manual selection by the user, thereby simplifying operations and reducing time loss
4Adaptability or versatility
If single display screen is used, then device simplicity is maintained, but multi-window display and detailed scenario viewing cannot be achieved
Solution Approach 1:
The patent extends the display capability from a single-screen dimension to a multi-screen spatial dimension by enabling cross-device task migration, where tasks can be displayed on multiple devices simultaneously or sequentially, providing multi-window functionality without adding physical screens to individual devices

AI summary
The method includes: obtaining, by a first terminal, a first gesture performed on a current page, and scaling down the current page, where the first gesture indicates to migrate a task; determining a second terminal, where the second terminal is at least one of at least one online device around the first terminal; determining content for migration based on the scaled-down current page; and sending the content for migration to the second terminal based on a second gesture to implement cross-device task migration, where the first gesture and second gesture are pre-specified hand motions.
