Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gesture-based interaction methods in virtual reality suffer from reduced precision and efficiency when operating distant objects due to the limitations of gesture extension lines and two-dimensional display interfaces, which hinder accurate and efficient interaction with virtual objects in three-dimensional spaces.
Innovation Solution
A method and apparatus for generating and controlling an operation interface by acquiring movement information of a user's operation hand, determining a three-dimensional movement path, and mapping it to a preset curved mesh model, utilizing a preset wiring method and angle to create a stereoscopic interface that enhances precision and efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the gesture extension line operation method is used, then the selection range for distant objects is increased, but the operation precision on distant objects is reduced
Solution Approach 1:
The patent transitions from two-dimensional screen-based gesture interaction to three-dimensional spatial gesture interaction. By mapping hand gestures to a three-dimensional curved mesh model representing the user's body surface, the system enables precise selection and operation of distant virtual objects through spatial positioning rather than extended linear gestures, thus resolving the contradiction between selection range and operation precision.
Solution Approach 2:
The patent employs a curved mesh model that conforms to the three-dimensional surface of the user's body as the interaction interface. This curved surface allows for more natural and precise gesture control when operating distant objects, as the curvature provides additional spatial degrees of freedom for gesture differentiation, thereby improving operation precision while maintaining extensive selection range.
2Ease of operation
If the direct gesture interaction method is used, then the operation difficulty on virtual objects at different positions is reduced, but the operation efficiency is reduced
Solution Approach 1:
The patent implements a dynamic gesture recognition system that adapts to the user's hand movements in real-time. The system continuously tracks the three-dimensional position and orientation of the hand, dynamically adjusting the interaction response based on the current gesture state. This dynamic approach reduces operation difficulty by providing intuitive feedback while improving efficiency through faster and more accurate object selection and manipulation.
Solution Approach 2:
The system incorporates real-time feedback mechanisms that provide visual, auditory, or haptic responses to user gestures. This feedback loop allows users to adjust their gestures more efficiently by receiving immediate confirmation of recognition, thereby reducing operation difficulty and improving overall interaction efficiency when manipulating virtual objects at various positions.
