Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile terminal users face operational inconvenience due to varying hand sizes and the inability to restrict access to inappropriate content, as fixed object sizes and positions do not accommodate different hand sizes and do not effectively prevent juveniles from accessing unsuitable content.
Innovation Solution
A method and device that adjust object attribute information on mobile terminals by determining user hand palm length using a gyroscope and somatotype characteristic information, and optionally using facial recognition to tailor operational object sizes and locations, while also determining user age to restrict access to inappropriate content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If fixed object sizes and positions are used in different Apps or interfaces, then device complexity is reduced and ease of manufacture is improved, but ease of operation deteriorates for users with different hand sizes
Solution Approach 1:
The patent implements dynamic adjustment of object attribute information based on detected hand size. The system changes the size and position of operational objects in real-time according to the user's hand dimensions, transforming fixed UI elements into adaptive, dynamic elements that optimize operability for each user.
Solution Approach 2:
The system detects hand size parameters and uses these measurements to adjust UI object parameters (size, position) accordingly. By changing the parameters of operational objects based on detected physical characteristics, the system achieves personalized optimization without requiring multiple pre-configured interface versions.
2Adaptability or versatility
If fixed object positions are used, then ease of manufacture is improved, but adaptability to different user hand sizes deteriorates
Solution Approach 1:
The system performs self-adjustment by automatically detecting hand size and configuring object attributes without requiring manual user input or selection. The device serves itself by using its own sensors to gather information and adapt the interface accordingly, eliminating the need for complex user setup procedures.
Solution Approach 2:
The system performs preliminary detection of hand size before the user begins operating the device. By detecting hand dimensions in advance (e.g., during initial contact or device pickup), the system can pre-adjust object attributes before the user needs to interact with them, ensuring optimal operability from the start.
3Reliability
If no user identification is implemented, then device complexity is reduced, but the ability to restrict inappropriate content access deteriorates
Solution Approach 1:
The patent replaces traditional manual user identification methods (such as passwords or ID entry) with automatic biometric detection based on hand size measurements. This substitution of the identification mechanism with a sensor-based physical characteristic detection system achieves reliable user identification while minimizing the complexity associated with traditional authentication systems.
