Solution Overview
Problem
Proximity motion recognition technologies in touch input schemes for portable devices face challenges in accuracy and fingerprint smudge reduction, often compromising between 2D and 3D interfaces, which affects user input precision and interface clarity.
Innovation Solution
An apparatus utilizing a combination of first and second sensors to detect user input at different ranges from a reference surface, with an information transfer controller to seamlessly switch between sensors and adapt the user interface, allowing for intuitive 2D to 3D transitions and icon management to prevent obscuration by the user's motion.

Engineering Contradiction Analysis
1Object-affected harmful factors
If proximity motion recognition is used to reduce fingerprint smudges, then the display screen is protected from smudges, but the accuracy of user input is reduced
Solution Approach 1:
The input detection space is segmented into multiple zones: a first input space closer to the display screen and a second input space farther away. The system uses different sensing methods for different zones, allowing proximity gestures in the second space to trigger actions without requiring contact with the first space, thus reducing smudges while maintaining input accuracy through zone-specific detection strategies
Solution Approach 2:
The system transitions from traditional 2D touch plane recognition to 3D spatial recognition by detecting input objects in space above the display. This adds a depth dimension to input detection, enabling the system to distinguish between proximity gestures (which should not cause smudges) and actual touch inputs (which require contact), thereby resolving the contradiction between smudge reduction and input accuracy
2Device complexity
If a single sensor is used for proximity detection, then the device complexity is reduced, but the accuracy of detecting user input at different ranges is compromised
Solution Approach 1:
The system merges multiple sensing capabilities into a unified input detection system. By combining detection of input objects in the first input space (closer to display) and second input space (farther from display) through a single controller, the system achieves accurate multi-range detection without proportionally increasing device complexity, as the merging is managed through integrated control logic
3Measurement precision
If the user interface is magnified to improve accuracy when motion is detected, then input precision is enhanced, but the interface layout becomes disrupted
Solution Approach 1:
The user interface is made dynamic and adaptive based on detected motion. When an input object is detected in the first input space, the system automatically magnifies the relevant interface elements and adjusts the layout to highlight the target area. This dynamic adaptation enhances input precision by focusing attention on the interaction zone while maintaining overall interface coherence through context-aware transformations
