Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Virtual reality systems face limitations in creating immersive and realistic experiences due to issues like motion sickness, computational burden, and the inability to effectively integrate shared environments, while augmented and mixed reality systems struggle with consistent virtual object placement across multiple user environments.
Innovation Solution
The development of systems and methods for colocating virtual content using persistent coordinate data and relational data from head-wearable devices, allowing virtual objects to be displayed consistently across multiple user environments by determining corresponding coordinate data and adjusting their display accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If virtual reality systems present a full 3D virtual environment to replace the real environment, then immersion and realism are improved, but motion sickness increases and computational burden increases
Solution Approach 1:
The patent merges virtual and real environments by allowing users to see both virtual content and real-world surroundings simultaneously through transparent or translucent display components. This hybrid approach maintains immersion in virtual elements while preserving awareness of the physical environment, thereby reducing motion sickness caused by complete environmental replacement.
Solution Approach 2:
The system dynamically adjusts the degree of virtual environment replacement based on user needs and context. Users can switch between fully immersive virtual modes and augmented modes where real environment is visible, allowing flexible adaptation that reduces motion sickness when complete virtual replacement is not necessary.
2Reliability
If virtual reality systems present a full 3D virtual environment, then immersion is improved, but computational burden (storage, processing power) increases
Solution Approach 1:
Instead of rendering complete 3D virtual environments at all times, the system renders only the necessary virtual elements partially or selectively. Virtual content is presented only where needed in the user's field of view, reducing computational load while maintaining sufficient immersion for the specific task at hand.
Solution Approach 2:
The system uses 2D displays that simulate 3D virtual environments through careful rendering of visual cues, rather than requiring actual 3D hardware. Virtual objects are represented as images that convey three-dimensional information through perspective, shading, and layering techniques, reducing the computational and hardware requirements while maintaining the illusion of immersion.
3Object-affected harmful factors
If augmented reality systems overlay virtual content on the real environment, then motion sickness is reduced, but consistent virtual object placement across multiple users is difficult to achieve
Solution Approach 1:
The patent introduces a coordinate transformation system that acts as an intermediary between different users' reference frames. Each user has their own head-mounted display with unique positioning and orientation, but the system translates virtual object coordinates into each user's specific reference frame, ensuring consistent placement across all users while allowing for individual device variations.
Solution Approach 2:
The system adds a mathematical transformation dimension to handle the complexity of multi-user coordination. By representing spatial relationships through coordinate transformations that account for each user's head position, orientation, and display characteristics, the system achieves precise virtual object placement consistency across multiple users despite hardware variations.

AI summary
Disclosed herein are systems and methods for colocating virtual content. A method may include receiving first persistent coordinate data, second persistent coordinate data, and relational data. A third persistent coordinate data and a fourth persistent coordinate data may be determined based on input received via one or more sensors of a head-wearable device. It can be determined whether the first persistent coordinate data corresponds to the third persistent coordinate data. In accordance with a determination that the first persistent coordinate data corresponds to the third persistent coordinate data, it can be determined whether the second persistent coordinate data corresponds to the fourth persistent coordinate data. In accordance with a determination that the second persistent coordinate data corresponds to the fourth persistent coordinate data, a virtual object can be displayed using the relational data and the second persistent coordinate data via a display of the head-wearable device. In accordance with a determination that the second persistent coordinate data does not correspond to the fourth persistent coordinate data, the virtual object can be displayed using the relational data and the first persistent coordinate data via the display of the head-wearable device. In accordance with a determination that the first persistent coordinate data does not correspond to the third persistent coordinate data, the method may forgo displaying the virtual object via the display of the head-wearable device.
