Vehicle Seat and Display Control for Continuous External Viewing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle control systems struggle to meet the diverse needs of occupants regarding external object confirmation, as they primarily focus on minimizing driver gaze movement without considering individual intentions or preferences.
Innovation Solution
A system that recognizes an occupant's gaze and determines their point of interest outside the vehicle, allowing for seat position control and display adjustments to maintain a continuous view of the interest point, while also synthesizing and displaying external interest information in a 3D format.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the driver's gaze movement is minimized to maintain focus on the road, then driving safety is improved, but the occupant's ability to observe external objects of interest is restricted
Solution Approach 1:
The system creates a virtual copy of the external object of interest by displaying it on the transparent display device. This allows the occupant to view the external object image without physically turning their head, thus maintaining both driving safety and the ability to observe external objects.
Solution Approach 2:
The transparent display device acts as an intermediary between the external object and the occupant's vision. It superimposes information about the external object onto the driver's field of view, enabling observation without direct gaze at the object.
2Ease of operation
If the seat position is adjusted to maintain continuous view of the point of interest during vehicle movement, then occupant satisfaction is improved, but system complexity increases
Solution Approach 1:
The system continuously monitors the vehicle's movement state and the occupant's gaze direction, then automatically adjusts the seat position and transparent display content in real-time. This feedback loop maintains optimal viewing conditions without requiring manual intervention from the occupant.
Solution Approach 2:
The seat position and display content are dynamically adjusted based on real-time vehicle movement and gaze detection. The system adapts continuously to changing conditions, ensuring the occupant can maintain viewing of the point of interest throughout the journey.
3Adaptability or versatility
If multiple occupants can simultaneously view their respective points of interest, then individual needs are satisfied, but coordination between multiple seats becomes complex
Solution Approach 1:
The system divides the vehicle interior into separate control zones for each occupant, with independent gaze recognition and seat control for each position. This segmentation allows each occupant to independently select and view their own point of interest without interfering with others.
Solution Approach 2:
The transparent display device and control system are designed to serve multiple occupants simultaneously with different functions. Each occupant can independently interact with the system to select their own external object of interest, and the system handles multiple seat adjustments concurrently.

AI summary
A system for controlling a vehicle includes: an occupant gaze recognition unit to recognize a gaze of an occupant in the vehicle; a point of interest determination unit to determine the point of interest among an external object visible through a side window of the vehicle based on the gaze of the occupant; and a seat position control unit to change a seat position of the occupant to enable a continuous stare at the point of interest according to a movement of the vehicle.
