Two-Way Mirror Video Conference Module for Life-Size 3D Presence
Find Innovative SolutionsGenerate Solutions
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.
