AR Vehicle Testing Graphics for Realistic Driver Reaction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During vehicle testing, virtual objects are not effectively rendered as real to vehicle operators, leading to a lack of realistic reaction, as humans within the environment can distinguish them as virtual.
Innovation Solution
A method and system that determine the position of a vehicle operator and execute an augmentative simulation to generate graphics of virtual objects, presenting them on an electronic display, such as AR glasses, to create a realistic augmented reality environment, where virtual objects appear as real, influencing the operator's reactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If virtual objects are introduced into the vehicle testing environment, then testing scenarios can be created without real instances of objects, but the vehicle operator may recognize them as virtual and not react accordingly
Solution Approach 1:
The patent uses augmented reality to create visual copies of virtual objects that are superimposed onto the real-world environment viewed by the vehicle operator. These graphical representations are designed to appear as real objects in the operator's field of view, making them indistinguishable from actual physical objects and eliciting natural operator reactions.
Solution Approach 2:
The augmented reality display system acts as an intermediary between the virtual testing environment and the vehicle operator. It translates virtual object data into graphical representations that are presented through the operator's field of view, creating a bridge that makes virtual objects perceivable as real without requiring physical presence.
2Manufacturing precision
If virtual objects are positioned and rendered accurately, then realism of testing scenarios is enhanced, but system complexity increases
Solution Approach 1:
The onboard computer is designed to perform multiple functions: executing the augmentative simulation, determining positions of both the vehicle operator and virtual objects, generating the graphical representations, and presenting them through the display system. This multi-functional approach consolidates what would otherwise require separate specialized systems.
Solution Approach 2:
The patent combines the simulation environment, positioning systems, graphics generation, and display presentation into an integrated augmented reality system. By merging these components and their functions into a unified system executed by the onboard computer, the patent reduces overall system complexity while maintaining positioning accuracy.
