Stereoscopic 3D Scene Interaction via Eyepoint Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current three-dimensional graphics technologies lack improved tools and user interface elements that allow for seamless interaction with virtual objects in a three-dimensional scene, particularly in providing a realistic and immersive experience by accurately rendering the scene based on the user's viewpoint and enabling direct manipulation of virtual objects in physical space.
Innovation Solution
A system and method that utilize stereoscopic displays and position input devices to determine the user's eyepoint, rendering the 3D scene with minimal distortions and allowing interaction through tools like a computer mouse or joystick, with the ability to present the scene in 'open space' for direct manipulation, using a combination of vertical and horizontal perspectives and blending displays to create a cohesive 3D environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional 2D display interfaces are used, then device complexity is low, but ease of operation for 3D scene interaction is poor
Solution Approach 1:
The patent transitions from traditional 2D display interfaces to 3D stereoscopic displays, adding a third dimension to the user interface. This allows virtual objects to be presented in three-dimensional space, enabling more natural and intuitive interaction with 3D scenes while maintaining manageable system complexity through the use of existing stereoscopic display technology.
2Ease of operation
If virtual objects are placed in open space for direct manipulation, then ease of operation improves, but device complexity increases
Solution Approach 1:
The patent introduces a positioning system as an intermediary that tracks the user's eyepoint and uses this information to render the 3D scene from the correct viewpoint. This mediator enables virtual objects to be accurately positioned in open space relative to the user's physical position, facilitating direct manipulation while managing the complexity of spatial rendering through viewpoint-based rendering techniques.
3Reliability
If stereoscopic displays with viewpoint rendering are used, then realism and immersion improve, but device complexity increases
Solution Approach 1:
The patent implements a feedback loop where the positioning system continuously tracks the user's eyepoint position and this information is fed back to the rendering system. The rendering system then adjusts the stereoscopic image generation based on the detected viewpoint, creating a dynamic feedback mechanism that enhances realism and immersion while managing rendering complexity through adaptive viewpoint-based rendering.
