Master-Slave Docking Interface for Seamless Task Continuity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable electronic devices, such as tablets and handheld devices, face challenges in seamless data continuity and user interface flexibility due to limited screen space, requiring complex setups or costly subscriptions for synchronization, and often interrupt task continuity when switching devices.
Innovation Solution
A method and system for docking portable electronic devices, where a master device with multiple displays can adapt its user interface to be displayed on a slave device, dividing the slave device's screen into portions corresponding to the master device's screens, allowing seamless communication and gesture-controlled interface management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cloud computing or server-based solutions are used for data synchronization across devices, then data continuity is improved, but cost and system complexity increase
Solution Approach 1:
The master device acts as an intermediary between multiple slave devices, managing data synchronization and task continuity locally without requiring external cloud servers. The master device receives data from one slave device and can transmit it to another slave device, eliminating the need for costly cloud subscriptions while maintaining data continuity across the device ecosystem.
2Ease of operation
If a single touch screen display is used to provide both display area and user interface, then device simplicity is improved, but display area and input area conflict
Solution Approach 1:
The system segments the display functionality by separating the master device display from the slave device display. The master device provides a dedicated user interface with full input capabilities, while the slave device provides a dedicated display area. This segmentation eliminates the conflict between display area and input area that plagues single-screen devices, as each device can be optimized for its specific function.
3Adaptability or versatility
If task transition between devices is enabled, then device versatility is improved, but task continuity is interrupted
Solution Approach 1:
The system performs preliminary actions by maintaining the application state and data in the master device while it is connected to slave devices. When a user switches between slave devices, the master device is already prepared with the necessary data and application context, enabling seamless task continuation without interruption. The master device pre-loads and maintains task state information so that switching devices does not require saving and reopening tasks.
4Adaptability or versatility
If handheld device user interface regime is adapted for tablet devices, then interface consistency is improved, but screen space efficiency deteriorates
Solution Approach 1:
The master device serves multiple functions by acting as both a standalone handheld device and as a control interface for slave devices. When connected to slave devices, the master device's interface adapts to provide appropriate control functionality while the slave devices provide the display area. This multi-functionality allows the system to maintain interface consistency across different device types while efficiently utilizing screen space, as each device performs the function it is best suited for.

AI summary
Systems and methods related to the user interface of docking portable electronic devices. A master device may be docked with a slave device to control operation of the slave device. The master device may be operable to display a user interface. The user interface of the master device may be adapted to be used with the slave device that may include different display and/or input devices than that of the master device. In one embodiment, the master device may be a handheld device such as a smart phone and the slave device may be a tablet device.
