Vehicle Input Detection Regions With Adaptive Gesture Lockout
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern vehicle systems require precise and intuitive user input operations that minimize driver distraction, preventing accidental activations and ensuring easy parameter adjustments.
Innovation Solution
A device with dual detection areas, each with a detection and blocking state, where the blocking state is activated after input in the first area to prevent accidental activation in the second area, using gesture recognition and adaptive lockout intervals based on input speed and direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple detection areas are provided for different parameter adjustments, then the versatility and functionality of the control system is improved, but the risk of accidental activations increases
Solution Approach 1:
The patent applies preliminary anti-action by implementing a blocking state that is activated in advance before accidental activation can occur. When a first input is detected in a first detection area, the control unit proactively activates a blocking state for a second detection area, preventing any subsequent unintended inputs from being registered. This preemptive measure directly counteracts the potential harmful effect of accidental activations while preserving the ability to provide multiple detection areas for different functions.
2Reliability
If the blocking time interval is extended to prevent accidental activations, then the reliability is improved, but the responsiveness and ease of operation deteriorates
Solution Approach 1:
The patent applies dynamics by making the blocking time interval adaptive rather than fixed. The control unit determines the blocking time interval based on the detected input characteristics, such as the type of gesture or the specific detection area involved. This dynamic adjustment allows the system to extend the blocking interval when accidental activation risk is high, while maintaining shorter intervals for routine operations, thereby balancing reliability with ease of operation.
3Ease of operation
If the driver needs to adjust multiple parameters frequently, then the ease of operation is improved, but the driver distraction and loss of time increases
Solution Approach 1:
The patent applies preliminary action by preparing the detection unit in advance with multiple detection areas that are ready for different parameter adjustments. The system anticipates the need for frequent parameter changes by having all detection areas pre-configured and available, eliminating the need for the driver to search for controls or reconfigure the system. This allows quick, intuitive adjustments without requiring the driver to take their eyes off the road for extended periods.

AI summary
The device for detecting an input of a user in a vehicle (1) comprises a detection unit (2) having a first and a second detection region, for each of which a detection state and a blocked state can be activated. The input of the user by a detection region is detectable in the detection state, whereas no input by a detection region is detectable in the blocked state. The device also comprises a control unit (3), which is designed to control the detection unit (2) such that, once an input in the first detection region has been detected for a specific blocking time interval, the blocked state is activated for the second detection region. In the method, an input is detected in a first detection region and then a blocked state is activated for a second detection region for a specific blocking time interval. The first detection region and the second detection region each have a detection state and a blocked state. Inputs of the user by a detection region are detectable in the detection state, and no inputs of the user by a detection region are detectable in the blocked state.
