Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional virtual and augmented reality systems lack unified scene acquisition and pose tracking capabilities, relying on external pose trackers and limited scene acquisition, which restricts their usefulness and immersion.
Innovation Solution
A wearable display system with integrated sensors for scene information acquisition and pose tracking, including cameras and inertial sensors, that generates virtual reality images based on acquired scene and pose data, allowing for self-contained unified scene acquisition and pose tracking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If external pose trackers are used to determine user pose, then pose tracking capability is provided, but device complexity and system integration increase
Solution Approach 1:
The patent combines the pose tracker with the head-mounted display device, integrating previously external components into the wearable unit itself. This merging eliminates the need for separate external pose tracking systems while maintaining accurate head pose determination capabilities through integrated cameras and processing units.
Solution Approach 2:
The head-mounted display device performs multiple functions including scene acquisition, pose tracking, and virtual reality rendering within a single integrated system. The device serves as both the display platform and the pose tracking system, eliminating the need for dedicated external pose trackers and reducing overall system complexity.
2Adaptability or versatility
If scene acquisition capability is added to AR systems, then immersion is improved, but device complexity increases
Solution Approach 1:
The patent integrates scene acquisition cameras directly into the head-mounted display device, combining multiple previously separate functions (scene capture, pose tracking, and rendering) into a unified system. This integration improves immersion by providing real-time scene awareness while managing complexity through consolidated hardware and software architecture.
3Ease of operation
If self-contained pose tracking is implemented in wearable display, then external trackers are eliminated, but manufacturing complexity increases
Solution Approach 1:
The patent integrates pose tracking functionality directly into the head-mounted display device, combining cameras, processors, and tracking algorithms within the wearable unit. This self-contained design eliminates dependency on external pose trackers, providing operational independence despite increased manufacturing requirements for integrating multiple components.

AI summary
Methods, systems, and computer readable media for unified scene acquisition and pose tracking in a wearable display are disclosed. According to one aspect, a system for unified scene acquisition and pose tracking in a wearable display includes a wearable frame configured to be worn by a user. Mounted on the frame are: at least one sensor for acquiring scene information for a real scene proximate to the user, the scene information including images and depth information; a pose tracker for estimating the user's head pose based on the acquired scene information; a rendering unit for generating a virtual reality (VR) image based on the acquired scene information and estimated head pose; and at least one display for displaying to the user a combination of the generated VR image and the scene proximate to the user.
