Cross-Display Pointer Control on Partially Folded Dual Screens
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Foldable mobile devices face challenges with limited display size and input controls, necessitating the use of larger devices for enhanced interaction, especially when partially unfolded, leading to alignment and viewing issues with dual displays.
Innovation Solution
A foldable electronic device with a cooperative user interface that allows single input control across connected devices, adjusting display portions and enabling instant control even when partially aligned, using a controller to manage display configurations and input interactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a foldable device is partially unfolded to enable handsfree viewing, then viewing comfort is improved, but alignment with the second device display becomes difficult
Solution Approach 1:
The system dynamically adjusts display configurations based on the foldable device's unfolding state. When partially unfolded, the controller automatically determines which portions of the folding display are viewable and configures the logical display portions accordingly, allowing the display alignment to adapt to different physical states rather than requiring precise manual alignment in each configuration
Solution Approach 2:
The system changes display parameters (which logical display portion is presented on which physical display portion) based on the detected unfolding state. The controller monitors the pivot sensor data and adjusts the display mapping parameters to ensure proper alignment and content presentation regardless of whether the device is fully unfolded, partially unfolded, or folded
2Area of stationary object
If a larger second electronic device is used to弥补 the limited display size of the mobile device, then display area is improved, but device complexity and setup requirements increase
Solution Approach 1:
The system merges the display functionalities of two separate devices into a unified experience. The foldable device and the second electronic device (tablet or laptop) work together as a single system, with the controller coordinating content presentation across both devices. This integration simplifies the user experience by providing seamless control and unified content delivery, reducing the perceived complexity despite using multiple devices
Solution Approach 2:
The foldable device is designed to function universally across multiple configurations (fully unfolded, partially unfolded, folded) and can pair with various types of second devices (tablets, laptops). The instant control feature and display coordination mechanism work across different device types and operating systems, providing a universal solution that adapts to different scenarios rather than requiring device-specific configurations
3Adaptability or versatility
If instant control is enabled across dual devices, then input control versatility is improved, but control management complexity increases
Solution Approach 1:
The controller acts as an intermediary that manages the instant control coordination between the foldable device and the second device. It receives input from either device, determines the appropriate target application and display location, and routes the input accordingly. This intermediary layer abstracts the complexity of cross-device control, providing a unified control experience without requiring users to manually manage control routing between devices

AI summary
An electronic device, a method, and a computer program product provide for single user pointer control across a partially unfolded display of the electronic device and a display of a second electronic device. A first portion of a folding display is aligned with the display of second electronic device with a second portion of the folding display is not aligned and is positioned on a support surface. The electronic device connects, via a communications subsystem, to a second electronic device having a display. The electronic device presents a first logical display portion on a first portion of the folding display and a second logical display portion on a second portion of the folding display. In response at least in part on the first housing being in an angled position to the second housing, the electronic device presents the second logical display portion on the display of the second electronic device.
