Solution Overview
Problem
Conventional augmented reality systems lack the ability to effectively integrate and synchronize multiple video sources and user interactions within a unified three-dimensional coordinate space, limiting the realism and interactivity of virtual medical models in surgical environments.
Innovation Solution
The Interaction Engine generates a unified three-dimensional coordinate space that renders a virtual 3D medical model alongside video data from multiple video sources, allowing concurrent display and control of camera, image, and robotic arm parameters, and detects user gestures to facilitate seamless interaction and manipulation of the model.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional augmented reality systems are used, then system simplicity is maintained, but the ability to integrate and synchronize multiple video sources and user interactions within a unified three-dimensional coordinate space is limited
Solution Approach 1:
The patent merges multiple video sources (stereo video feeds, endoscopic video, exoscopic video) into a unified augmented reality display system with a common three-dimensional coordinate space, allowing concurrent display and synchronization of multiple video feeds while maintaining system integration
2Quantity of substance
If multiple video sources are integrated in conventional systems, then video source quantity increases, but synchronization and visualization quality deteriorate
Solution Approach 1:
The system implements feedback mechanisms through the interaction engine that continuously monitors and adjusts the synchronization of multiple video sources, using gesture detection and parameter control to maintain temporal and spatial alignment across stereo video feeds, endoscopic video, and exoscopic video
3Adaptability or versatility
If conventional AR displays are used, then ease of operation is maintained, but interactivity and realism of virtual medical models deteriorate
Solution Approach 1:
The system employs gesture-based interaction where the user's natural hand movements are automatically detected and translated into control commands for the virtual medical model, eliminating the need for complex manual controls or additional input devices while enhancing interactivity through intuitive gesture recognition
