Vehicle Passenger Eye-Tracking for Roadside Object Perception
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for monitoring passenger perception of advertising content in a traffic space are costly and limited by the range of sensors, which cannot effectively record views from passing vehicles.
Innovation Solution
A method and system that utilize a data memory to store object positions and orientations, combined with eye-tracking technology to determine if a passenger in a vehicle has perceived an object by matching the vehicle's geographic position and viewing direction with the object's position and orientation, eliminating the need for extensive sensor arrays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If sensors are integrated into advertising objects to detect passenger viewing, then detection capability is improved, but costs increase and monitoring range is limited
Solution Approach 1:
Instead of placing sensors in advertising objects to detect passengers (object-centered approach), the patent inverts the approach by placing sensors in vehicles to detect objects along the route (passenger-centered approach). This allows monitoring of multiple advertising objects throughout the day without requiring sensors in each object, thereby reducing costs and expanding monitoring range while maintaining detection capability.
Solution Approach 2:
The sensor system in the vehicle serves multiple functions: it detects advertising objects, determines geographic position, tracks passenger viewing direction, and monitors multiple objects simultaneously throughout the day. This multi-functional approach replaces the need for dedicated sensors in each advertising object, reducing overall system complexity and cost.
2Reliability
If sensors are placed in advertising objects, then object perception can be detected, but the range of monitoring is limited to the sensor's detection distance
Solution Approach 1:
The patent transitions from a static monitoring approach (sensors fixed in advertising objects with limited range) to a dynamic approach where the detection point moves with the vehicle along the route. This dimensional change allows the system to monitor objects at various distances and locations throughout the day, effectively expanding the monitoring range while maintaining reliable perception detection.
Data Source
AI summary
The invention relates to a method for monitoring a passenger of a vehicle in which the geographic position of the vehicle is recorded, and a viewing direction of the passenger is recorded by means of a eye-tracking device. A data memory is accessed in which objects and geographic positions assigned to them are saved and, by using the recorded geographic position of the vehicle, it is detected whether one of the objects is located in the environment of the vehicle, and whether the object in the environment of the vehicle was perceived by the passenger depending on the recorded viewing direction of the passenger, the recorded geographic position of the vehicle, and the geographic position of the detected object in the environment of the vehicle.
