Auxiliary Device Anchoring for Accurate Volumetric Object Interaction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Accurately and efficiently determining user engagement with volumetric computer-generated objects is difficult, particularly when the objects have large depths relative to the device, leading to false positives in user interaction detection.
Innovation Solution
An electronic device anchors volumetric computer-generated objects to an anchor point of an auxiliary device based on positional information, using a combination of image data and positional sensor data from the auxiliary device, adjusting the anchoring position based on the object's dimensions to improve interaction accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the auxiliary device is used to detect user engagement with volumetric computer-generated objects, then user interaction detection capability is improved, but false positive detection occurs when objects have large depth relative to the device
Solution Approach 1:
The patent dynamically adjusts the anchor point position on the auxiliary device based on the depth dimension of the volumetric object. When the object has a large depth relative to the device, the system automatically selects a different anchor point (e.g., distal end vs. proximal end) to maintain accurate engagement detection. This dynamic adaptation resolves the contradiction by preventing false positives while preserving detection capability across varying object geometries.
Solution Approach 2:
The system changes the anchoring parameter (anchor point location) based on the depth-to-device ratio of the volumetric object. By adjusting this parameter according to object characteristics, the system maintains reliable detection accuracy without generating false positives, effectively resolving the contradiction between detection capability and reliability.
2Device complexity
If the anchor point is fixed at a single position on the auxiliary device, then device complexity is reduced, but occlusion occurs that prevents effective use of the auxiliary device and precise manipulation
Solution Approach 1:
Rather than using a fixed anchor point, the system dynamically selects from multiple possible anchor points based on the volumetric object's properties. This dynamic approach prevents occlusion issues while maintaining relatively simple device architecture, resolving the contradiction between device simplicity and operational ease.
Solution Approach 2:
The auxiliary device is designed with multiple potential anchor points that can serve different functions depending on the object being manipulated. This multi-functionality allows the device to adapt to various object types and sizes without increasing physical complexity, thereby maintaining ease of operation across different use cases.
