Hand Detection for Dynamic Interface Layout
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Smaller computing devices often have content blocked by the user's hand and user interfaces can be difficult to access, leading to a suboptimal user experience due to varying hand sizes and inconvenient button placement.
Innovation Solution
The computing device determines which hand is holding it using sensors such as orientation, image, hover, and touch sensors, allowing it to configure the interface and content placement for improved accessibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If content is displayed at a particular location on the display screen, then the content can be clearly visible, but the user's hand blocks the view of the content
Solution Approach 1:
The patent dynamically adjusts content placement based on real-time detection of hand position and device orientation. The system continuously monitors which hand is holding the device and automatically repositions content on the display screen to avoid hand obstruction, transforming a static display layout into a dynamic one that adapts to user conditions.
Solution Approach 2:
The patent applies different display configurations to different regions of the display screen based on hand position detection. By identifying whether the left or right hand is holding the device, the system selectively places content in optimal regions that are not blocked by the user's hand, creating locally optimized viewing areas.
2Length of moving object
If the computing device is made smaller, then portability is improved, but content placement becomes difficult to access due to hand size variations
Solution Approach 1:
The system dynamically reconfigures interface element positions based on detected hand orientation and device holding posture. By continuously adapting button and interface locations according to which hand is holding the device and the specific holding orientation, the system maintains optimal accessibility despite the device's compact size.
Solution Approach 2:
The patent changes display and interface parameters such as content position, button location, and interface orientation based on detected hand characteristics and device orientation. This parameter adaptation allows the same compact device to provide optimized accessibility for users with different hand sizes and holding styles.
3Device complexity
If the user interface is configured at a specific location, then the interface layout is simplified, but it becomes difficult for users with different hand sizes to access the interface
Solution Approach 1:
The interface layout is transformed from a fixed configuration to a dynamic one that automatically adapts to the user's hand position and device holding orientation. The system detects which hand is holding the device and reconfigures interface elements accordingly, maintaining simplicity while achieving adaptability.
Solution Approach 2:
The patent creates a universal interface system that can serve users with different hand sizes and preferences through a single adaptive layout mechanism. By detecting hand orientation and device holding posture, the system automatically configures the interface to be optimally accessible for each user, eliminating the need for manual configuration.
Data Source
AI summary
A computing device can obtain information about how the device is held, moved, and/or used by a hand of a user holding the device. The information can be obtained utilizing one or more sensors of the device independently or working in conjunction. For example, an orientation sensor can determine whether a left hand or a right hand is likely rotating, tilting, and/or moving, and thus holding, the device. In another example, a camera and/or a hover sensor can obtain information about a finger position of the user's hand to determine whether the hand is likely a left hand or a right hand. In a further example, a touch sensor can determine a shape of an imprint of a portion of the user's hand to determine which hand is likely holding the device. Based on which hand is holding the device, the device can improve one or more computing tasks.
