Driver Risk Alert Presentation Using Gaze Recognition Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drivers often feel annoyed by constant alerts for out-of-vehicle risks when they recognize the risks, leading to reduced usage of risk information presentation systems.
Innovation Solution
An information presentation apparatus that detects out-of-vehicle risks and the driver's gaze direction, adjusting the presentation mode based on recognition, highlighting risks when not recognized and reducing alerts when recognized.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the system presents out-of-vehicle risk information continuously to ensure driver awareness, then risk detection effectiveness is improved, but driver annoyance increases leading to reduced system usage
Solution Approach 1:
The system dynamically adjusts the presentation mode of risk information based on real-time detection of driver gaze direction and recognition state. When the driver is determined to be recognizing the risk object, the system reduces or stops information presentation; when recognition is not detected, the system actively presents information. This dynamic adaptation resolves the contradiction by making the system both reliable (maintaining risk awareness) and acceptable (reducing annoyance through conditional suppression).
Solution Approach 2:
The system implements a feedback loop that continuously monitors driver gaze direction and recognition state, then uses this feedback to adjust information presentation. The recognition determination section analyzes whether the driver is viewing the risk object, and this determination feeds back to control the presentation mode. This closed-loop feedback mechanism ensures risk detection effectiveness while adapting to driver state to prevent annoyance and maintain system usage.
2Ease of operation
If the system reduces alerts when driver recognizes risks to prevent annoyance, then driver acceptance is improved, but risk detection effectiveness may be compromised
Solution Approach 1:
The system dynamically adjusts information presentation based on real-time driver recognition state. When recognition is detected through gaze analysis, the system suppresses or reduces alerts to prevent annoyance. When recognition is not detected, the system maintains active information presentation to ensure safety. This dynamic control resolves the contradiction by conditionally applying alert suppression only when driver awareness is confirmed.
Solution Approach 2:
The system uses feedback from the recognition determination section to control information presentation. The gaze detection section continuously monitors driver attention, and this feedback determines whether to maintain, reduce, or suppress risk information presentation. This feedback mechanism ensures that alert reduction occurs only when driver acceptance is maintained, preserving risk detection effectiveness.
3Adaptability or versatility
If the system uses gaze detection to determine driver recognition, then information presentation can be optimized, but device complexity increases
Solution Approach 1:
The system integrates gaze detection functionality into the existing risk information presentation system, allowing the same apparatus to perform both risk detection and driver recognition assessment. By making the system multi-functional, the need for completely separate gaze detection equipment is reduced, and the system achieves presentation optimization without proportionally increasing overall complexity.
Solution Approach 2:
The system uses the driver's own gaze pattern as the basis for determining recognition state, eliminating the need for external input devices or complex interaction mechanisms. The gaze detection leverages natural driver behavior (looking at risk objects) to trigger system responses, making the system adaptable without requiring additional complex interfaces or controls.

AI summary
An information presentation apparatus includes an out-of-vehicle risk detection section that is configured to detect an out-of-vehicle risk object, a gaze detection section that is configured to detect a gaze direction of a driver of the vehicle, a recognition determination section that is configured to determine whether the out-of-vehicle risk object is recognized by the driver based on a detection result by the out-of-vehicle risk detection section and a detection result by the gaze detection section, and an information presentation section that is configured to present, to the driver, out-of-vehicle risk information regarding the out-of-vehicle risk object in a presentation mode. The information presentation section is further configured to change the presentation mode depending on whether the out-of-vehicle risk object is recognized by the driver based on a determination result by the recognition determination section.
