Two-Way Mirror Video Conference Module for Life-Size 3D Presence
Solution Overview
Problem
Current video conferencing technologies fail to provide an adequate sense of presence, especially in small spaces, as they typically limit the view to a small screen and do not effectively display a life-size, head-to-toe appearance of participants, which is crucial for applications like medical examinations.
Innovation Solution
A self-contained video conference module using a two-way mirror to create a three-dimensional visual effect by reflecting a backdrop, allowing for life-size, head-to-toe viewing without 3D glasses, and connecting through a cloud-based network for real-time interactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a traditional video conference system with a monitor and camera is used, then users can view remote participants, but the sense of presence is inadequate and participants appear limited to a small screen rather than life-size
Solution Approach 1:
The patent transitions from 2D screen display to 3D immersive environment by using two-way mirrors positioned at 45-degree angles to reflect images onto a backdrop, creating a volumetric space where remote participants appear as life-size three-dimensional figures rather than flat screen images
Solution Approach 2:
The patent introduces two-way mirrors as intermediary optical elements between the camera and the user's field of view. These mirrors reflect the captured image onto a backdrop, mediating the transformation from 2D screen output to 3D immersive display while maintaining the compact room footprint
2Area of stationary object
If prior art configurations with horizontally angled two-way mirrors are used, then a reflected view can be captured, but the configuration is limited to displaying only the upper body and cannot achieve head-to-toe life-size display
Solution Approach 1:
The patent rotates the two-way mirrors from horizontal angulation to vertical orientation at 45-degree angles, enabling the optical path to capture and display the full vertical extent of participants from head to toe rather than being limited to upper body views
Solution Approach 2:
The patent changes the orientation parameter of the two-way mirrors from horizontal angulation to vertical positioning, and adjusts the backdrop distance to optimize the full-body display, transforming the system's capability from partial to complete body coverage
3Reliability
If horizontally angled two-way mirrors are used in prior art, then reflection can be achieved, but gravity causes sagging that limits the size and quality of the mirror
Solution Approach 1:
The patent changes the mirror orientation from horizontal symmetry to vertical asymmetry, positioning mirrors at 45-degree angles where the vertical mounting configuration resists gravitational sagging and enables larger mirror surfaces without compromising structural stability
Solution Approach 2:
The patent positions mirrors at specific 45-degree angular orientations rather than horizontal planes, creating an asymmetric angular configuration that distributes gravitational stress and enables larger mirror surfaces to maintain their optical quality
4Measurement precision
If a self-contained module is used to provide life-size 3D display, then head-to-toe viewing is achieved, but the device complexity increases
Solution Approach 1:
The patent combines multiple functions into a single integrated module: the camera captures images, two-way mirrors reflect and transform the images to 3D, and a backdrop provides the immersive environment. This merging of capture, transformation, and display functions into one compact unit achieves life-size 3D display while managing system complexity through functional integration

Implementation Method 1
A camera captures an image of you and uses a two-way mirror to create a three-dimensional visual effect by reflecting a backdrop
Data Source
AI summary
In a system and method for video communications, a user in an observation zone views a display image rendered on a vertically oriented screen through a two-way mirror in front of the screen. The two-way mirror is vertically angled at substantially 45 degrees, and reflects a part of a side wall in the observation zone. The backdrop for the light-emitting portion of the display image is provided by the reflection that is superimposed by the two-way mirror onto the non-light-emitting portion of the display image. The backdrop provides the light-emitting portion of the display image with a depth relationship that is observable when the user views the display image along a line of vision that extends straight through the two-way mirror to the screen behind the two-way mirror. A camera embedded in the side wall captures video of the user that is reflected by the two-way mirror from the observation zone back into the camera.
