Mixed Reality Navigation Using Elevator and Jump Teleportation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mixed reality (MR) technologies in the AEC industry are hindered by the time-consuming and confusing process of navigating 3D models, particularly when moving between floors or structures, as users must walk through the virtual environment, which is inefficient and prone to errors.
Innovation Solution
An MR system that includes an elevator feature and a jump feature, allowing users to teleport between locations within a 3D model, enabling quick and accurate movement between floors and to any visible or obscured points, using a navigation application that processes user requests to calculate new locations and update the displayed images accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If users walk through the virtual environment to navigate between locations, then they can experience the 3D model in a realistic manner, but the navigation process becomes time-consuming and inefficient
Solution Approach 1:
The patent replaces the mechanical walking navigation system with a teleportation system that uses computational geometry and coordinate transformation. Instead of physically moving through the virtual environment step-by-step, the system calculates direct paths between points using 3D model data and instantly transports the user's viewpoint, eliminating navigation time while maintaining spatial accuracy.
Solution Approach 2:
The patent introduces an intermediary navigation system that acts as a mediator between the user and the 3D model. This intermediary layer processes navigation requests by calculating optimal paths, transforming coordinates, and rendering intermediate views, thereby enabling instant teleportation while preserving the user's sense of spatial orientation and model context.
2Ease of operation
If users walk through lengthy or circuitous paths to reach destinations, then they can maintain spatial orientation, but the navigation becomes confusing and inefficient
Solution Approach 1:
The patent applies preliminary action by pre-calculating navigation paths and storing geometric data about the 3D model environment before navigation begins. The system prepares coordinate transformations, identifies optimal routes, and pre-processes visual information so that when a user initiates teleportation, the navigation occurs instantly without requiring time-consuming real-time calculations or lengthy physical traversal.
3Loss of information
If the navigation system provides detailed 3D model information, then users can accurately understand the structure, but the complexity of navigating and interpreting the data increases
Solution Approach 1:
The patent replaces complex manual navigation mechanics with automated computational systems that handle 3D model data processing. The system uses algorithms to automatically interpret geometric information, calculate spatial relationships, and present data in intuitive visual formats, thereby maintaining complete model information while reducing the operational complexity users must manage.

AI summary
A mixed reality (MR) system that implements navigation methods for 3D models in MR environments. The navigation methods allow a user to navigate themselves about a 3D model (such as an MR environment including one or more buildings/structures) while in an MR environment. The navigation methods include an elevator feature or navigation mode that allows the user to move accurately between “floors” of the 3D model used to provide the MR environment (move to a next upper or lower floor from their present position). The navigation techniques include a jump feature or navigation mode. The jump feature allows the user to move to any point in an MR environment created using a 3D model that they can presently see in the display of the MR environment or a location that may be partially obscured from the user's view.
