Vehicle Gaze Command Control for Hands-Free Voice Activation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current voice command systems in vehicles require physical button activation, which is cumbersome and inefficient, especially when multiple occupants want to initiate commands without physical access.
Innovation Solution
A vehicle command operation system that uses gaze detection technology to determine a focal point based on an occupant's eye gaze, allowing vehicle operations to be performed without the need for physical button activation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a physical button is required to activate voice commands, then the system can reliably initiate commands, but the ease of operation deteriorates when occupants cannot physically access the button
Solution Approach 1:
The patent replaces the mechanical button-pressing system with an optical detection system using cameras and image processing to detect gaze direction. This allows command initiation through eye gaze detection combined with voice commands, eliminating the need for physical button access while maintaining reliable command initiation through multi-modal verification
Solution Approach 2:
The patent introduces gaze detection as an intermediary mechanism between the occupant and the voice command system. The gaze detection system acts as a mediator that identifies which occupant intends to issue a command, enabling remote occupants to initiate commands without physical button access while preventing unauthorized activation
2Reliability
If physical button activation is required, then unauthorized voice activation is prevented, but the productivity of vehicle operations decreases due to additional manual steps
Solution Approach 1:
The patent replaces the mechanical button-pressing step with automated gaze detection and image processing. The system automatically identifies the occupying driver's gaze direction and combines it with voice command recognition, eliminating the manual button-pressing step while maintaining security through multi-modal verification
Solution Approach 2:
The system performs preliminary gaze detection and occupant identification before accepting voice commands. By pre-establishing which occupant is authorized to issue commands through gaze detection, the system enables immediate voice command execution without requiring subsequent physical button activation, thus improving operational efficiency
Data Source
AI summary
In various examples, systems and methods are disclosed herein for a vehicle command operation system that may use technology across multiple modalities to cause vehicular operations to be performed in response to determining a focal point based on a gaze of an occupant. The system may utilize sensors to receive first data indicative of an eye gaze of an occupant of the vehicle. The system may utilize sensors to receive second data indicative of other data from the occupant. The system may then calculate a gaze vector based on the data indicative of the eye gaze of the occupant. The system may determine a focal point based on the gaze vector. In response to determining the focal point, the system causes an operation to be performed in the vehicle based on the second data.
