Vehicle Gesture Recognition Using Sequential Touch Input
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional gesture recognition systems in vehicles suffer from low recognition accuracy and increased costs due to the need for specific hand positioning and additional input devices, which complicates efficient gesture recognition and manipulation.
Innovation Solution
A vehicle gesture recognition system utilizing a camera sensor and a manipulation means with multiple input devices arranged in a line, where sequential touches within specific time durations are recognized as directional or functional gesture signals, allowing for cost-effective and accurate gesture recognition without requiring high-cost configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a conventional gesture recognition system uses a camera or sensor to recognize hand gestures at a specific location, then the system can implement gesture control, but the recognition accuracy is low and the hand must be moved to a specific location which reduces ease of operation
Solution Approach 1:
The system divides the gesture recognition function into two parts: a camera for detecting hand presence and a separate manipulation means (touch panel or buttons) for receiving confirmed input. This segmentation allows the camera to broadly monitor the driving area while the manipulation means provides precise input confirmation, resolving the contradiction between broad gesture detection and precise recognition.
Solution Approach 2:
The manipulation means acts as an intermediary between the driver's intent and the infotainment system. Instead of directly recognizing complex hand gestures in space, the system uses the manipulation means to translate driver input into recognized commands, improving both accuracy and ease of use by providing a familiar interaction interface.
2Measurement precision
If additional touch pads or dial devices are added to improve gesture recognition accuracy and ease of manipulation, then the recognition accuracy improves, but the cost increases
Solution Approach 1:
The manipulation means is designed to serve multiple functions: it acts as both the interface for gesture confirmation and the control panel for infotainment operations. By making the manipulation means multi-functional, the system avoids adding separate dedicated gesture control devices, thereby improving recognition capability without increasing manufacturing cost.
Solution Approach 2:
The system merges the gesture detection function with the existing manipulation means (touch panel or buttons). Instead of adding a separate gesture control device, the patent combines multiple functions into the existing manipulation interface, reducing overall system cost while maintaining improved gesture recognition capability.
3Reliability
If the system requires the hand to be moved to a specific location for gesture recognition, then the gesture can be recognized, but the operation becomes less convenient and response time increases
Solution Approach 1:
The camera continuously monitors the driving area in advance, preparing to detect hand gestures before they are fully formed or before the driver intends to input. This preliminary detection allows the system to be ready for input, reducing the time the driver needs to spend on the gesture while maintaining reliable recognition through the subsequent manipulation means confirmation.

AI summary
A system for recognizing a gesture of a vehicle and a method for controlling the same. The system includes gesture recognition means having a sensor for recognizing a gesture of a driver, manipulation means having a plurality of input means for recognizing a touch of the driver, a controller that receives a signal from the gesture recognition means and the manipulation means, and display means for displaying a screen by receiving the signal from the controller.
