Windshield Light Feedback for Pointed Object Recognition in Vehicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional technologies do not provide effective feedback to a vehicle occupant regarding the recognition of a pointed object through the windshield, which can impede the driver's visual confirmation of their surroundings.
Innovation Solution
A data processing device installed in a vehicle that includes an occupant state recognition unit, peripheral circumstances acquisition unit, object recognition unit, relative direction determination unit, and a light control unit to control the emission of an oblong shaped light-emitting unit below the windshield, providing feedback through light-emitting appearances that indicate the relative direction of the pointed object.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If feedback is provided to the driver about the recognized pointed object, then the driver receives information about the object, but the driver's visual confirmation of surroundings may be impeded
Solution Approach 1:
The patent uses a light-emitting unit as an intermediary device to provide feedback information to the driver without requiring direct visual attention to a display screen. The light emissions serve as a mediator that conveys object recognition results through subtle visual cues in the driver's peripheral vision, thus providing information feedback while minimizing visual obstruction and maintaining the driver's primary focus on the road.
Solution Approach 2:
The feedback is provided through localized light emissions at specific positions corresponding to the recognized object's location, rather than using a full-screen display. This local quality approach provides targeted information about the pointed object while keeping the rest of the visual field clear, thus reducing overall visual obstruction while maintaining effective communication of critical information.
2Loss of information
If a display screen is used to show feedback information, then information is clearly presented to the driver, but the driver's attention is diverted from the road
Solution Approach 1:
The patent replaces the traditional mechanical/electronic display screen system with a light-emitting system that uses optical signals instead of graphical interfaces. This substitution allows information to be conveyed through intuitive light cues that can be perceived peripherally, eliminating the need for the driver to shift attention to a screen and maintaining focus on the road while still delivering feedback information effectively.
3Loss of information
If the light-emitting unit provides detailed information about the pointed object, then the driver receives comprehensive feedback, but the light may distract the driver
Solution Approach 1:
The patent applies partial action by providing only the essential information about the pointed object through light emissions rather than displaying all possible details. The light-emitting unit conveys key object characteristics and location information sufficient for driver awareness without providing excessive information that would require intense visual attention and cause distraction, thus balancing information completeness with driver safety.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device provides suitable feedback to the vehicle occupant by indicating the recognized object's relative direction without obstructing their view of the surroundings, ensuring safety and awareness of the pointed object.
Implementation Method 1
a light-emitting unit 15 installed below the windshield of the vehicle in the width direction of the vehicle body
Data Source
AI summary
The disclosed data processing device installed in a vehicle includes an occupant state recognition unit that recognizes the action of an occupant of a vehicle pointing outside the vehicle, a peripheral circumstances acquisition unit that acquires the peripheral circumstances around the vehicle, an object recognition unit that recognizes the object pointed at by the occupant based on the recognition results obtained by the occupant state recognition unit and the acquisition results obtained by the peripheral circumstances acquisition unit, a relative direction determination unit that determines the relative direction of the object with respect to the vehicle, and a light control unit that controls the light emission appearance of an oblong shaped light-emitting unit installed above or below the windshield of the vehicle. The light control unit controls the light-emitting appearance such that the relative direction is identifiable based on the recognition results of the object recognition unit.
