3D Object Interaction Validation for False-Trigger-Free Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional displays, particularly VR/AR devices and naked-eye 3D displays, suffer from false triggering during gesture interactions due to multiple interactive elements at varying depths, leading to inaccurate user interactions.
Innovation Solution
An object interaction method that collects interaction information, extracts key point information at different stages, and determines the validity of the interaction behavior based on spatial and temporal constraints to prevent false triggering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If gesture interaction is used in interactive stereoscopic space with multiple interactive elements, then user interaction capability is improved, but false triggering occurs leading to interaction accuracy deterioration
Solution Approach 1:
The interaction process is segmented into distinct stages: interaction preparation stage (object approaching), interaction occurrence stage (object contacting display content), and interaction ending stage (object retracting). By segmenting the continuous gesture into discrete phases with specific validation criteria for each stage, the system can accurately distinguish intentional interactions from false triggers while maintaining support for multiple interaction types.
2Adaptability or versatility
If multiple interactive elements are presented simultaneously in stereoscopic space, then interaction versatility is improved, but false triggering increases
Solution Approach 1:
The patent extends interaction validation from traditional 2D touch coordinates to 3D stereoscopic space by incorporating depth information (Z-axis). The behavior trajectory analysis considers spatial position, movement direction, and depth changes, allowing the system to distinguish between gestures directed at different depth planes. This dimensional expansion enables multiple interactive elements at varying depths to coexist without causing false triggering, as the system can determine which element the gesture is actually targeting based on the object's three-dimensional motion path.
3Adaptability or versatility
If gesture recognition is performed in three-dimensional space, then interaction functionality is improved, but system complexity increases
Solution Approach 1:
The system performs preliminary analysis of the object's behavior trajectory during the interaction preparation stage, before the actual interaction occurs. By pre-processing the gesture data and extracting key movement characteristics (approach direction, speed, trajectory shape) in advance, the system reduces the computational burden during the interaction occurrence stage. This preliminary action enables complex 3D gesture recognition to be broken down into manageable validation steps, reducing overall system complexity while maintaining full 3D interaction functionality.

AI summary
An object interaction method of stereoscopic space and a display device, to constrain the interaction behavior of interactive objects, and effectively improve the false triggering problem generated during interaction in the stereoscopic space. The method includes: collecting interaction information between an object and display content in an interactive stereoscopic space, the interaction information representing a behavior trajectory of an interaction behavior between the object and the display content; extracting key point information of the object in different interaction stages from the interaction information, the key point information being used to reflect a behavior feature of the interaction behavior; and determining whether the interaction behavior of the object is valid according to the key point information.
