Vehicular Gesture Input Cancellation via Multi-Functional Sensors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicular input apparatuses become complex due to the need for multiple components to recognize and manage gestures, leading to unintended operations, which can cause operator stress and incorrect manipulations.
Innovation Solution
A vehicular input apparatus comprising a gesture sensor, an external device controller, and an output stop unit, where the gesture sensor detects non-contact gestures, and the external device controller outputs operation signals to first external devices after a predetermined period, with the output stop unit halting signals upon detection by contact or proximity sensors, simplifying the configuration and reducing unintended operations.

Engineering Contradiction Analysis
1Reliability
If the input apparatus recognizes additional gestures to modify operations, then unintended operations are reduced, but the number of components increases and the apparatus becomes complicated
Solution Approach 1:
The existing contact sensor and proximity sensor, originally designed for manipulating a second external device (e.g., touch panel operations), are made multi-functional by enabling them to also serve as gesture cancellation sensors. When these sensors detect contact or proximity during a gesture operation, they generate detection signals that trigger the output stop unit to cancel the gesture-based operation, thereby eliminating the need for separate cancellation components.
Solution Approach 2:
The patent merges the gesture recognition function with the existing contact/proximity sensing system. Instead of adding separate components for gesture cancellation, the system combines multiple functions (gesture detection, contact detection, proximity detection, and operation control) into a unified control architecture where the external device controller integrates all these sensing inputs and coordinates their responses through the output stop unit.
2Reliability
If the apparatus waits for a predetermined period before outputting operation signals, then unintended operations are reduced, but the response time increases
Solution Approach 1:
The system dynamically adjusts its response behavior based on real-time sensor inputs. Instead of a fixed delay for all operations, the apparatus continuously monitors contact sensor and proximity sensor signals during the predetermined period. If cancellation signals are detected, the operation is immediately halted, making the response time adaptive rather than static, thus reducing unnecessary waiting time while maintaining safety.
Solution Approach 2:
The apparatus prepares for potential cancellation by continuously monitoring contact and proximity sensors during the predetermined waiting period. This preliminary monitoring allows the system to be ready to cancel operations immediately if needed, rather than waiting passively. The output stop unit is pre-configured to receive and process cancellation signals, enabling rapid response when cancellation is required.

AI summary
A vehicular input apparatus includes a gesture sensor, an external device controller, and an output stop unit. The gesture sensor detects a gesture that is a non-contact gesture. The external device controller outputs an operation signal corresponding to the gesture detected by the gesture sensor to a first external device. When the gesture sensor detects the gesture, the output stop unit causes the external device controller to stop outputting the operation signal in response to a detection signal from at least one of a contact sensor and a proximity sensor for manipulating a second external device. The external device controller outputs the operation signal to the first external device after a second predetermined period of time.
