Gaze-Tracking Projection for Construction Site Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Operators of construction machines face challenges in accurately and efficiently modifying sites to match desired plans due to the need for constant reference to site plans, which can be cumbersome and time-consuming, especially for inexperienced operators.
Innovation Solution
A method that determines the operator's gaze direction using head or gaze tracking systems to dynamically display relevant information, such as site overlays and machine operations, via projection systems or smart glasses, allowing for real-time adjustments based on the operator's focus and site changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If operators constantly reference paper site plans or display screens in the cab, then they can ensure accuracy in matching the desired site plan, but this increases the time required for operations and reduces efficiency
Solution Approach 1:
The patent introduces a projection system as an intermediary that projects the desired site plan directly onto the construction site. This allows operators to see the plan overlay on the actual terrain without needing to constantly reference paper plans or cab displays, thereby maintaining accuracy while improving efficiency.
Solution Approach 2:
The patent transitions from two-dimensional reference (paper plans or cab screens) to three-dimensional visualization by projecting the site plan directly onto the terrain. This dimensional change allows operators to see the plan in context with the actual site, eliminating the need to constantly cross-reference between the plan and the terrain.
2Manufacturing precision
If operators use paper site plans or cab displays to monitor the current state of the site, then they can ensure accurate modification of the site, but this requires constant attention and reference, increasing the complexity of the operation
Solution Approach 1:
The patent merges the desired site plan visualization directly with the actual site terrain by projecting the plan onto the ground. This combination allows operators to see both the target state and the current state in the same field of view, eliminating the need to switch between separate reference materials and reducing operational complexity.
3Manufacturing precision
If inexperienced operators reference site plans frequently, then they can learn and ensure accuracy, but this significantly slows down the operation compared to experienced operators
Solution Approach 1:
The projection system acts as an intermediary that provides continuous visual feedback of the desired site plan directly on the terrain. This eliminates the need for operators to frequently stop and reference paper plans, allowing both inexperienced and experienced operators to work at higher speeds while maintaining accuracy.

AI summary
A system for displaying information to an operator of a machine comprises a head tracking system and a projection system. One system for displaying information uses a projection system and a see-through display to present two-dimensional images to an operator. One system uses a projection system and a see-through display to present three-dimensional images to an operator. One system uses a pair of smart glasses to display information to a user based a direction a user is looking.
