The portability of computing devices constrains display size, making it difficult to present increasing amounts of information effectively to users, limiting user interaction and experience.
Innovation Solution
A portable electronic device with a display that conveys stereoscopic 3-D information, utilizing a displacement sensor to capture spatial-position information and control logic to analyze and associate changes in 3-D spatial position with icons, allowing for interactive operations such as modifying icon information, location, or executing applications without direct touch.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If display size is increased to present more information, then information capacity is improved, but device portability deteriorates
Solution Approach 1:
The patent applies dimensionality change by transitioning from a traditional 2-D display interface to a 3-D spatial interface. Multiple 2-D fields are arranged in 3-D space with spatial offsets, allowing users to perceive depth and interact with icons positioned at different distances from the display surface. This enables significantly more information to be displayed within the same physical device dimensions, resolving the contradiction between information capacity and device portability.
2Ease of operation
If display size is increased to provide more interaction space, then user interaction capability is improved, but device portability deteriorates
Solution Approach 1:
The patent extends interaction space by utilizing 3-D spatial positioning instead of 2-D screen real estate. Users can interact with icons positioned at various depths and locations in 3-D space, providing more interaction opportunities without increasing the physical device footprint. The displacement sensor enables detection of 3-D gestures, further enhancing interaction capability within compact dimensions.

AI summary
A portable electronic device provides signals corresponding to information to a display that allows a viewer to perceive 3-dimensional (3-D) depth, where the information includes multiple icons in a user interface that are arranged in 2-dimensional (2-D) fields that are spatially offset along a direction orthogonal to the 2-D fields. Then, the portable electronic device captures spatial-position information (such as a distance with respect to a surface of the display) associated with at least a digit of the viewer. The portable electronic device analyzes the spatial-position information to determine a change in a 3-D spatial position of at least the digit, and associates the change in the 3-D spatial position with at least one of the icons. Next, the portable electronic device performs the operation based on the change in the 3-D spatial position and at least the one of the icons.
