Solution Overview
Problem
Conventional VR systems face challenges such as motion sickness, disorientation, high computational burden, and inability to leverage real-world sensory data, while AR and MR systems offer advantages by maintaining a view of the real environment, but may struggle with interactivity and shared environments.
Innovation Solution
A mixed reality system that combines real and virtual environments using a transmissive display and sensors to create a mixed reality environment (MRE) where virtual objects interact with real objects, allowing users to perceive and interact with both environments simultaneously.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If VR systems present a full 3D virtual environment to replace the real environment, then user immersion is improved, but motion sickness and disorientation occur due to mismatch between visual field and inner ear sensing
Solution Approach 1:
The patent merges the real environment view with virtual environment elements through augmented reality technology. Instead of completely replacing the real environment with a virtual one, the system overlays virtual objects and information onto the user's view of the real world, allowing the inner ear and visual system to remain aligned while still providing immersive virtual experiences.
Solution Approach 2:
The patent segments the visual information into real environment components and virtual environment components, presenting them in a layered manner. The real environment is maintained as the base layer while virtual elements are added as overlays, allowing the user's sensory systems to process them separately and reducing conflict between visual and vestibular inputs.
2Reliability
If VR systems present a full 3D virtual environment, then user immersion is improved, but computational burden increases significantly
Solution Approach 1:
The patent applies partial action by rendering only the necessary virtual elements that need to be overlaid on the real environment, rather than rendering a complete 3D virtual environment. This reduces computational requirements while still achieving the desired immersive effect for the specific application.
3Object-affected harmful factors
If AR/MR systems maintain a view of the real environment, then motion sickness is reduced, but interactivity with virtual objects becomes more difficult
Solution Approach 1:
The patent adds depth and spatial dimensionality to virtual objects displayed in the augmented reality environment. By rendering virtual objects with proper depth cues, shadows, and occlusion relationships, the system creates a sense of three-dimensionality that makes interaction more intuitive while maintaining the real environment view.
4Reliability
If VR systems create a complete virtual environment, then immersion is improved, but the ability to leverage real-world sensory data is lost
Solution Approach 1:
The patent combines virtual environment elements with real-world sensory data by overlaying virtual objects onto the user's view of the real environment. This allows the system to leverage actual sensory input from the real world (visual, auditory, tactile) while still providing immersive virtual experiences, eliminating the loss of real-world information.
Data Source
AI summary
Exemplary systems and methods for creating spatial contents in a mixed reality environment are disclosed. In an example, a location associated with a first user in a coordinate space is determined. A persistent virtual content is generated. The persistent virtual content is associated with the first user's associated location. The first user's associated location is determined and is associated with the persistent virtual content. A location of a second user at a second time in the coordinate space is determined. The persistent virtual content is presented to the second user via a display at a location in the coordinate space corresponding to the first user's associated location.
