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 with two touch-sensitive screens that can be oriented in different configurations, allowing the user to switch between primary and secondary screens based on input or events, enhancing usability and versatility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single touch screen display is used to provide both content display and user input interface, then the device maintains a simple form factor, but the display becomes visually cluttered and user experience deteriorates
Solution Approach 1:
The device is divided into two separate display surfaces: a first display surface for content presentation and a second display surface for user input. This segmentation allows each surface to have a dedicated function, eliminating visual clutter on the content display while maintaining ease of operation through a separate input interface.
2Area of moving object
If the display area is increased to provide more content space, then the available input area decreases, but if input area is increased, then display space is reduced
Solution Approach 1:
The device utilizes a foldable or flexible display structure that expands into multiple dimensions. When folded, the first and second display surfaces are positioned at different spatial orientations, allowing both to be accessible simultaneously. This dimensional approach resolves the area trade-off by providing both display and input space without requiring a compromise in either dimension.
3Area of moving object
If a virtual keypad is superimposed on the display, then the display area is maximized, but the display becomes obscured and interpretation of information becomes difficult
Solution Approach 1:
By separating the input function to a second display surface, the first display surface maintains full visibility of content without superimposed virtual keypads. The second display surface provides the necessary input interface, ensuring information clarity on the primary display while maintaining full input functionality.
4Area of stationary object
If the device is designed with a small form factor, then portability is improved, but the screen space becomes limited and complex interactions become difficult
Solution Approach 1:
The device employs a dynamic, reconfigurable display structure that can transition between folded and unfolded states. This dynamic design allows the screen space to expand when needed for complex interactions while maintaining a compact form factor for portability. The flexibility of the structure enables the device to adapt its physical configuration based on usage requirements.

AI summary
Methods and devices for selectively presenting a user interface on a second screen. More particularly, the method includes a change in the display mode of a multiple screen device from a first screen to a second screen while the device is closed. The change in the display mode may be made in response to one or more actions conducted by a user in a gesture capture region. The actions can include tapping the device in the gesture capture region. The actions can also include further input received in a window provided in response to the taps in the gesture capture region.
