Construction Equipment Blind Spot Display Using Gaze-Tracked Markers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Construction equipment drivers face blind spots that hinder their ability to recognize surrounding objects, leading to safety accidents and reduced work efficiency due to the need to divert gaze from the work site to monitor displays.
Innovation Solution
A blind spot display device for construction equipment that includes detectors, a display in front of the driver's eyes, a gaze tracker, and a controller to provide real-time markers and alarms for objects in the blind spot through smart glasses, allowing the driver to maintain focus on the work site.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a monitor is provided in the construction machinery to display the surroundings, then the driver can recognize blind spots, but the driver has to turn the gaze to the monitor during work and cannot respond immediately
Solution Approach 1:
The patent introduces smart glasses as an intermediary device between the driver and the blind spot information. The smart glasses display markers for detected objects directly in the driver's field of view, serving as a mediator that delivers information without requiring the driver to shift attention to a separate monitor, thus resolving the contradiction between information access and response time
Solution Approach 2:
The patent transitions from a two-dimensional monitor display to a three-dimensional spatial display through smart glasses. By projecting markers directly into the driver's visual field at appropriate spatial positions, the system allows the driver to perceive blind spot information without lateral or vertical gaze shifts, effectively adding a spatial dimension to information presentation
2Area of stationary object
If the driver monitors the surroundings through various mirrors, then the driver can observe the construction equipment, but there is a blind spot in the range where the driver may monitor the construction equipment with the naked eye
Solution Approach 1:
The patent replaces the mechanical mirror-based monitoring system with an electronic sensor and display system. Detectors (cameras, sensors) mounted on the construction equipment capture visual information from blind spots, and this information is processed and displayed through smart glasses, substituting mechanical optical systems with electronic sensing and display technologies to eliminate blind spots
Solution Approach 2:
The patent creates visual copies of the blind spot areas by using detectors to capture images and videos from regions not visible to the driver. These copied visual representations are then displayed as markers through smart glasses, allowing the driver to perceive objects in blind spots without directly observing them, thus expanding the observable area while maintaining safety
3Productivity
If the driver focuses on the work site, then the work efficiency is improved, but the driver cannot recognize objects in the blind spot
Solution Approach 1:
The patent merges the work site view and blind spot information into a single visual field through smart glasses. The markers for objects in blind spots are superimposed on the driver's natural field of view, allowing the driver to simultaneously perceive both the work site and potential hazards without dividing attention, thus combining productive focus with safety awareness
Solution Approach 2:
The system performs preliminary detection and marking of objects in blind spots before they become hazards. By continuously monitoring and pre-marking potential obstacles through detectors and smart glasses, the system allows the driver to maintain focus on work while having advance awareness of surrounding objects, preventing accidents before they occur
