Dual Display Window Positioning for Phone Applications
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Handheld computing devices with single touch screen displays face challenges in balancing display graphics and input areas due to limited screen space, leading to user frustration and productivity loss, especially when complex interactions are required.
Innovation Solution
A dual multi-display handheld device that is dockable with a smartpad, featuring two touch-sensitive screens, a configurable area, and a gesture capture region, allowing for enhanced user interface configurations and efficient information display and input management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a virtual keypad or user interface scheme is superimposed on the display, then input capability is provided, but the display space for application content is reduced
Solution Approach 1:
The display is segmented into multiple independent windows, allowing the interface to occupy only the necessary portion of the screen while leaving ample space for application content. Each window can be independently positioned and sized, enabling flexible allocation of display real estate between interface elements and content areas.
Solution Approach 2:
The interface transitions from a full-screen overlay to a windowed approach, adding the dimension of spatial organization. Windows can be arranged in various configurations (side-by-side, stacked, overlapping), enabling the interface to coexist with content in three-dimensional display space rather than competing for two-dimensional space.
2Ease of operation
If the application is squeezed into a smaller portion of the display to accommodate the interface, then input functionality is maintained, but the difficulty of interpreting displayed information increases
Solution Approach 1:
Different regions of the display are assigned different qualities and functions. The interface window maintains its operational functionality while the content window provides optimized viewing space. Each area is tailored to its specific purpose, with the content area having higher visual quality and the interface area having higher interactivity.
Solution Approach 2:
The window sizes and positions are dynamic and can be adjusted by the user. This allows the interface to expand or contract based on the situation, and the content area to expand when the interface is minimized or moved, enabling flexible optimization of both input capability and content interpretability.
3Device complexity
If a single display is used, then device simplicity is maintained, but screen space is limited leading to user frustration
Solution Approach 1:
The system creates a virtual three-dimensional workspace on the two-dimensional display by implementing window stacking and layering. Windows can be arranged in depth, with some in the foreground and others in the background, effectively increasing the usable display space without adding physical screens.
Solution Approach 2:
Windows can be nested within other windows or arranged in hierarchical structures, allowing multiple applications and interface elements to coexist in a compact manner. This nesting capability enables efficient use of limited screen real estate while maintaining access to multiple functions.

AI summary
Methods and devices for selectively presenting a user interface for a phone application are provided. More particularly, a change in the display mode of a multiple screen device can be determined after the device is rotated. More particularly, a presentation of a user interface for a call log of a phone application can be retained after receiving a signal indicating the rotation of the device. However, based on the direction of the rotation, the call log detail window may be moved from a first screen to a second screen, the call log detail window is changed to a landscape orientation, and the call log detail window is expanded to cover the first and second screens.
