Vehicular Glance Lighting Apparatus Using Color-Coded Peripheral Light
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional in-vehicle display systems divert a driver's attention by requiring them to focus on character or icon information, increasing the risk of accidents during high-speed travel.
Innovation Solution
A vehicular glance lighting apparatus that outputs vehicle-running information as light in the driver's peripheral vision, using a system comprising an input unit, vehicle-sensing unit, storage unit, control unit, and glance light unit, allowing intuitive information delivery without diverting the driver's attention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If character or icon type information is displayed on LCD displays or head-up displays, then vehicle-running information can be provided to the driver, but the driver's driving attention is diverted due to the need to directly gaze at and recognize the displayed characters or icons
Solution Approach 1:
The patent uses color-coded light emission from the glance light unit to convey different types of vehicle-running information. Different colors represent different information categories or alert levels, allowing the driver to quickly comprehend information without reading characters or icons, thus eliminating the time loss associated with visual recognition of text-based displays.
Solution Approach 2:
The invention extracts the essential information content from traditional character/icon displays and presents it in a simplified light-based format. By removing the need for text rendering and visual processing, the system delivers only the critical information elements in a form that can be perceived at a glance, thereby resolving the contradiction between information delivery and attention diversion.
2Area of stationary object
If display devices present character or icon type information over the windshield, then information can be provided without obstructing the driver's field of vision, but the driver still requires considerable time to recognize the characters or icons
Solution Approach 1:
The system uses color-coded light signals that can be perceived instantly by the driver's peripheral vision. Different colors convey different information types or urgency levels, enabling the driver to understand the information content without reading characters or icons, thus maintaining an unobstructed field of vision while eliminating recognition time.
Solution Approach 2:
The invention transitions from two-dimensional character/icon displays on the windshield to a different dimensional approach by using color-coded light emission in the driver's peripheral vision area. This spatial and perceptual dimensionality change allows information to be conveyed through color perception rather than text reading, resolving the contradiction between field of vision and recognition time.
3Loss of information
If the driver gazes at characters or icons on display devices, then vehicle-running information can be perceived and recognized, but driving attention is diverted for several seconds during high speed traveling
Solution Approach 1:
The patent employs color-coded light signals that convey vehicle-running information through immediate color perception rather than text reading. The driver can understand information content at a glance through color recognition, eliminating the need to divert attention for several seconds and thereby maintaining driving safety during high-speed travel.
Solution Approach 2:
The system extracts only the essential information elements from traditional displays and presents them in a simplified light-based format that requires minimal cognitive processing. By removing characters and icons entirely, the driver can perceive information without diverting attention, thus resolving the contradiction between information perception and driving safety.

AI summary
The present invention provides a vehicular glance lighting apparatus which provides a driver with vehicle-running information as light of a background screen and includes a driver attention function through prompt information delivery such that the driver visually recognizes as a background screen the vehicle-running information needed essentially or minimally for running the vehicle without requiring the driver's attention to avoid dissipation of the driver's sight, thereby preventing the driver's driving attention from being diverted, and a method for controlling the same. The vehicle-running information related with the running of a vehicle to be outputted in the form of light as a background screen, so that a driver can perceive the vehicle-running information without diverting or obstructing the driver's driving attention, thereby enhancing the driver's ability to cope with a vehicle travel risk during the traveling of the vehicle.
