Windshield Projection System for Driver Attention Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle information transmission technologies are inadequate in effectively notifying drivers of potential risks and objects around the vehicle, as they often fail to provide clear and intuitive visual cues that align with the driver's field of view and attention.
Innovation Solution
A vehicle information transmission system that projects light from an array of LEDs onto the windshield, using adjustable light sources and control units to create virtual images at specific positions and angles, based on detected risks and driver gaze, to notify the driver of objects and directions with varying luminance and color patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If light is projected only at the detected position of an object, then the driver can recognize the object's location, but the driver's attention becomes concentrated at one spot causing uneven attention distribution and potential blind spots
Solution Approach 1:
The notification light is divided into multiple independent light-emitting units arranged in an array. Each unit can be individually controlled to emit light at different positions, allowing the system to segment attention notification across multiple locations rather than concentrating it at a single point.
Solution Approach 2:
The system transitions from single-point notification to multi-point spatial distribution by projecting light at multiple positions simultaneously. This adds a spatial dimension to attention notification, creating a distribution pattern across the windshield rather than a single focal point.
2Illumination intensity
If the notification light is too bright, then the driver can easily recognize the information, but the driver's eyes become distracted and fixed on the light source
Solution Approach 1:
The notification light emits light in a blinking or pulsing manner rather than continuously. This periodic action maintains visibility and attracts driver attention while preventing the eyes from becoming fixed on the light source, as the intermittent nature encourages periodic glances rather than sustained fixation.
3Device complexity
If a single color of light is used, then the display is simple and clear, but the driver cannot distinguish between different types of risks or objects
Solution Approach 1:
The system uses multiple light-emitting units that can emit different colors of light (e.g., red, yellow, green). By varying the color of the notification light, the system conveys different types of information about detected objects or risks, allowing the driver to distinguish between various situations without complicating the overall display mechanism.
