Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current motor vehicle operating systems face challenges in providing precise and rapid operator control while minimizing driver distraction, especially in noisy environments, and require improvements to effectively handle voice commands in conjunction with eye-tracking technology.
Innovation Solution
An operating device for motor vehicles that integrates a display system, an eye tracker to determine the operator's viewing direction, and a microphone for acoustic command input, allowing for the representation of symbols associated with vehicle functions, selection of these symbols based on eye direction, and execution of functions via recognized acoustic commands, while ensuring the driver's attention is focused on the display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If voice recognition is used for operator control, then ease of operation is improved, but recognition precision deteriorates due to background noise in the vehicle interior
Solution Approach 1:
The patent introduces an eye tracker as an intermediary device that mediates between the driver and the voice recognition system. The eye tracker detects the driver's viewing direction and uses this information to select appropriate vocabulary items for voice command recognition, thereby improving recognition accuracy in noisy environments without adding manual control steps
Solution Approach 2:
The system implements feedback by using the eye tracker to continuously monitor the driver's viewing direction and dynamically adjust the vocabulary items available for voice recognition based on what the driver is looking at. This feedback loop enables the system to adapt to the driver's intentions and improve recognition precision in real-time
2Adaptability or versatility
If the display shows multiple functions and options, then adaptability is improved, but device complexity increases
Solution Approach 1:
The system performs preliminary action by using the eye tracker to pre-select vocabulary items and functions based on the driver's viewing direction before voice commands are given. This allows the system to narrow down the range of possible interpretations and present a simplified interface tailored to the driver's current focus
Solution Approach 2:
The patent applies dynamics by making the display content and voice recognition vocabulary dynamically adjustable based on the driver's viewing direction. The system continuously adapts the presented options and available commands according to what the driver is looking at, creating a flexible and context-aware interface

AI summary
In a method for the operator control of a motor vehicle having a display for displaying variable information, a symbol assigned to a function pertaining to the motor vehicle is shown with the aid of the display, the viewing direction of an operator of the motor vehicle is ascertained, and the function pertaining to the motor vehicle is subsequently executed in response to recognition of an acoustic command assigned to the function pertaining to the motor vehicle, while the viewing direction is aimed toward the display.
