Solution Overview
Problem
Mobile computing devices with larger display sizes pose challenges for users in maintaining a secure grip during single-handed operation, leading to difficulties in navigating user interfaces due to the device's dimensions and reach limitations.
Innovation Solution
A computer-implemented method and system for motion-based user interfaces that dynamically generate navigation interfaces, allowing single-handed operation by detecting changes in movement, pressure, and orientation of the device, enabling users to interact with the interface using a uniform grip and movement-based interactions.

Engineering Contradiction Analysis
1Area of stationary object
If display screen size and dimensions are increased, then display clarity and capability are improved, but ease of operation deteriorates due to grip and reach limitations
Solution Approach 1:
The navigation interface dynamically adapts its configuration based on detected device movements and pressure changes. The interface transitions between different modes (e.g., expanded view, condensed view, contextual menus) in response to user gestures, making the large screen operable with one hand by allowing users to access different portions of the interface through motion-based interactions rather than requiring direct manual reach to all elements.
2Area of stationary object
If display screen size is increased, then display capability is improved, but device complexity increases due to navigation challenges
Solution Approach 1:
The system introduces motion detection and pressure sensing as intermediary mechanisms between the user and the large display interface. Instead of directly manipulating interface elements on a large screen, users perform gestures (tilting, rotating, pressing edges) that are detected by sensors and translated into interface navigation actions, effectively mediating the interaction between the user's hand and the distant screen elements.
3Ease of operation
If motion-based navigation is implemented, then ease of operation is improved for single-handed use, but measurement precision requirements increase for detecting movements and pressure changes
Solution Approach 1:
The system performs preliminary calibration and threshold setting for motion and pressure detection. By pre-establishing acceptable ranges for gesture movements and pressure thresholds, the system reduces the precision requirements during actual operation. Users perform gross motor movements (tilting the device, pressing edges) rather than fine motor control, and the system has pre-configured detection parameters to recognize these intentional gestures despite variations in execution precision.

AI summary
A method, system, and computer program product for motion-based user interfaces are provided. The method identifies a navigation mode indication. A navigation interface is generated at a display device and configured based on the navigation mode indication to include a first graphical content. At least a portion of the navigation interface is modified based on one or more movements of the mobile computing device. A portion of the navigation interface is selected based on detecting a pressure change on at least a portion of a mobile computing device. The method presents a second graphical content on the display device based on the selected portion of the navigation interface.
