Gaze-Tracked Blind Spot Display for Construction Equipment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Construction equipment drivers face challenges in recognizing blind spots, leading to accidents due to momentary mistakes or distractions, as existing solutions like Around View Monitoring systems require the driver to divert gaze from the work site to monitor screens.
Innovation Solution
A blind spot display device for construction equipment that includes detectors to identify objects around the equipment, a smart glass display in front of the driver's eyes, a gaze tracker, and a controller that analyzes the driver's gaze direction and displays markers for objects in blind spots on the smart glass, minimizing the driver's need to look away from their work.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an Around View Monitoring system with monitor is used to display blind spot information, then the driver can recognize objects in blind spots, but the driver's gaze deviates from the work site and immediate response is delayed
Solution Approach 1:
The patent introduces smart glasses as an intermediary device between the detector and the driver's eyes. The smart glasses display blind spot information directly in the driver's field of view, serving as a mediator that delivers safety information without requiring the driver to shift gaze to a separate monitor, thus resolving the contradiction between safety information access and response time
Solution Approach 2:
The patent transitions the display interface from a traditional 2D monitor to a wearable smart glass interface that overlays information directly onto the driver's visual field. This dimensional change allows the driver to perceive blind spot information within the same spatial plane as the work site, eliminating the need for gaze deviation and maintaining immediate response capability
2Area of stationary object
If the driver monitors surroundings through various mirrors, then the driver can observe left and right and rear areas, but there remain blind spots that cannot be monitored with the naked eye
Solution Approach 1:
The patent replaces the mechanical mirror-based monitoring system with an electronic detection and display system. Detectors (cameras, sensors) electronically capture blind spot areas and transmit this information to smart glasses, substituting the mechanical reflection method with electronic imaging and display, thereby expanding the observable area while eliminating remaining blind spots
Solution Approach 2:
The smart glasses serve multiple functions: they display blind spot information, provide spatial orientation context, and can integrate with the construction equipment's existing communication systems. This multi-functionality allows a single device to address multiple monitoring needs, comprehensively expanding the driver's observable area across all directions
3Loss of information
If the driver turns gaze to the monitor to check blind spot information, then the driver can recognize surrounding objects, but the driver is unable to respond immediately
Solution Approach 1:
The system performs preliminary detection of blind spot objects using detectors positioned on the construction equipment. This advance detection allows the information to be prepared and displayed on smart glasses before the driver needs to respond, enabling continuous awareness without interrupting the driver's focus on the work site and maintaining immediate response capability
