Automated Handedness Detection via Input Device Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing computer systems are not capable of automatically determining user handedness, leading to inefficiencies and discomfort for left-handed users due to input devices and UI layouts optimized for right-handed individuals, resulting in user fatigue and decreased productivity.
Innovation Solution
A system and method that assesses user handedness by tracking the position and orientation of an input device in 3D space relative to objects, allowing for automatic configuration of input devices and UI elements to optimize functionality and convenience based on the user's handedness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If input devices and UI layouts are optimized for right-handed users, then usability for the majority (90%) is improved, but usability for left-handed users deteriorates
Solution Approach 1:
The system dynamically adjusts UI layout and input device configuration based on real-time detection of user handedness. The interface transitions from a static right-handed optimization to a dynamic configuration that adapts to each user's dominant hand, allowing the same system to serve both right-handed and left-handed users effectively
Solution Approach 2:
The system automatically detects user handedness through tracking input device position and orientation, and self-configures the UI layout without requiring manual user input. The system serves itself by identifying user characteristics and making appropriate adjustments autonomously
2Loss of information
If manual handedness input is required at system initiation, then handedness information is obtained, but the system cannot detect user changes or new users
Solution Approach 1:
The system continuously monitors input device position and orientation to detect changes in user handedness. This feedback mechanism allows the system to identify when a different user logs in or when handedness preferences change, automatically updating the UI configuration without requiring manual re-input
Solution Approach 2:
The patent replaces the mechanical approach of manual user input with an automated optical/electronic tracking system. Instead of relying on users to manually enter their handedness, the system uses sensors and algorithms to detect and interpret user behavior patterns, substituting automated detection for manual configuration
3Area of stationary object
If 3D objects are placed far from the user input device, then more display area is available, but user movement distance and fatigue increase
Solution Approach 1:
The system applies different spatial arrangements to different regions of the interface based on the user's dominant hand. Frequently accessed objects and controls are positioned in the dominant hand's optimal reach zone, while less frequently used items are placed in peripheral areas, creating a localized optimization that balances display area with user convenience
