Vehicle Gesture Control Interaction State Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle control methods using hand gestures can result in involuntary function activation, particularly during interactions with passengers, and reduce the panel of available gestures, making them difficult for drivers to perform safely.
Innovation Solution
A method that detects control gestures and determines the interaction state of the individual with their environment, using monitoring devices to assess whether the gesture is voluntary, involving signal transmission and response confirmation to ensure intended function control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If hand gesture control is implemented for vehicle functions, then ease of operation is improved, but reliability deteriorates due to involuntary function activation
Solution Approach 1:
The system implements feedback by detecting the driver's interaction state through monitoring devices (cameras, microphones, sensors) and using this information to confirm or reject gesture commands. When a gesture is detected, the system checks whether the driver is actively interacting with the environment, and only executes the command if the interaction state confirms intentional use, thereby preventing involuntary activations while maintaining gesture control convenience
Solution Approach 2:
The patent introduces an intermediary verification mechanism between gesture detection and function execution. The interaction state detection system acts as a mediator that analyzes contextual information (head position, eye direction, voice activity) to determine whether a detected gesture is intentional. This intermediary layer filters out involuntary gestures while preserving legitimate control commands
2Reliability
If natural gestures are excluded to prevent involuntary control, then reliability is improved, but ease of operation deteriorates due to reduced gesture panel
Solution Approach 1:
The system dynamically adjusts the interpretation of gestures based on the detected interaction state. The same physical gesture can be interpreted differently depending on context: if the driver is actively conversing with a passenger, the gesture is likely ignored; if the driver is alone or not engaged in conversation, the same gesture is executed. This dynamic interpretation allows natural gestures to be used intentionally while filtering out involuntary ones
3Reliability
If interaction state verification is added to gesture control, then involuntary commands are reduced, but device complexity increases
Solution Approach 1:
The system uses multi-functional monitoring devices that serve both safety monitoring and gesture verification purposes. The same cameras, microphones, and sensors used for driver monitoring and safety systems are repurposed to detect interaction state for gesture control verification. This universal use of existing components adds verification capability without requiring entirely new hardware systems
Solution Approach 2:
The system leverages existing driver monitoring infrastructure and environmental sensors to automatically determine interaction state without requiring additional dedicated verification devices. The system uses information already being collected for other purposes (safety monitoring, telematics) to enable reliable gesture control, reducing the need for separate verification subsystems

AI summary
The invention relates to a method of controlling at least one function of a vehicle by an individual present on board that vehicle, through the performance, by that individual, of at least one control gesture associated with that function, according to which it is provided for the steps of: a) detection of the control gesture (CG) performed by the individual in a detection zone of said vehicle, b) determination of a state of interaction (El) between said individual and his environment, and c) depending on the state of interaction determined in step b), control of the function associated with said control gesture detected in step a).
