Solution Overview
Problem
Current videoconferencing technologies face challenges in simulating in-person interactions due to poor camera angles, residual projection beams in see-through displays, and the complexity of setting up inclined optics for holographic effects, leading to distractions and poor user experience in both personal and group communication settings.
Innovation Solution
The development of compact, ultra-compact staging systems with vertical optics for hologram creation, combined with advanced camera positioning and eye contact solutions, and innovative display technologies that conceal residual projection beams and enhance brightness, allowing for immersive and realistic videoconferencing experiences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If see-through projection screens are used to display videoconferencing images, then the physical environment can be seen through the display, but residual projection beams illuminate the meeting room environment creating distractions
Solution Approach 1:
The patent extracts and removes the harmful residual projection beam from the viewer's field of vision by positioning the projection screen at an angle and using a hood structure to conceal the projection source and residual light paths, while maintaining the see-through display functionality
Solution Approach 2:
The patent introduces a hood structure as an intermediary element that blocks and conceals the residual projection beam from reaching the viewer's eyes, while allowing the projected image to remain visible on the screen surface
2Illumination intensity
If cameras are mounted away from the display screen to avoid blocking the image, then the display quality is maintained, but the camera angle creates a parallax problem where people appear to be looking away
Solution Approach 1:
The patent nests the camera within the display assembly structure, positioning it at the edge of the screen housing where it can capture images at the correct eye-level angle while remaining concealed within the overall display unit architecture
Solution Approach 2:
The patent uses the display screen surface itself as a reflective copy to capture the camera view, allowing the camera to be positioned at an optimal angle while the screen reflection provides the correct visual alignment for eye contact
3Adaptability or versatility
If inclined optics are used for holographic effects in videoconferencing, then the realism is improved, but the setup complexity and space requirements increase significantly
Solution Approach 1:
The patent replaces rigid inclined optical elements with flexible transparent films that can be positioned at the display surface, achieving the holographic reflection effect while eliminating the need for complex mechanical support structures and reducing setup complexity
Solution Approach 2:
The patent transitions from using inclined three-dimensional optical elements to using two-dimensional transparent films positioned at the display surface, achieving the same visual effect with reduced spatial requirements and simplified configuration
