Head-Mounted Display Layout for Mixed Reality Video Pass-Through
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing head mountable computer systems for augmented reality lack efficient integration of multiple cameras and displays to provide seamless mixed reality experiences, particularly in capturing and projecting images while maintaining a compact and user-friendly design.
Innovation Solution
A head mountable device with a nasal bridge, multiple forward and rearward facing displays, cameras, and a controller that facilitates mixed reality video pass-through by integrating cameras with displays and sensors to capture and project images, including a shroud to hide sensor brackets and depth projectors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple cameras and displays are integrated into a single head mountable device, then mixed reality experience quality is improved, but device complexity increases
Solution Approach 1:
The device is divided into distinct functional modules: camera assembly with multiple forward-facing cameras positioned at specific locations, display assembly with rearward-facing displays, sensor bracket for depth sensing, and shroud for housing. Each module performs a specific function in the mixed reality pipeline, allowing independent optimization and easier assembly while collectively enabling the complex mixed reality experience.
Solution Approach 2:
The shroud is designed to hide the sensor bracket and depth projector within its structure, nesting these components inside the shroud housing. This nesting approach consolidates multiple components into a single integrated unit, reducing the overall footprint and simplifying the external appearance while maintaining internal functionality for mixed reality processing.
2Shape
If a shroud is added to hide sensor brackets, then aesthetic appearance is improved, but device complexity increases
Solution Approach 1:
The shroud serves as an intermediary component between the visible exterior and the internal sensor bracket assembly. It mediates the contradiction by providing a clean aesthetic appearance from the outside while simultaneously housing and protecting the complex sensor bracket and depth projector internals, thus hiding technical complexity from the user's view.

AI summary
A head mountable device includes a front cover defining an external forward facing surface and a nasal bridge, a first rearward facing display, a second rearward facing display, a first forward facing camera, a second forward facing camera, and a controller electrically coupled to the first forward facing camera, the second forward facing camera, the first rearward facing display, and the second rearward facing display. The nasal bridge is disposed between the first forward facing camera and the second forward facing camera and the controller is configured to cause mixed reality video pass-through from the first forward facing camera to the first rearward facing display including a first image and from the second forward facing camera to the second rearward facing display including a second image.
