Touch Input Gesture Recognition for Vehicle Control Panels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing input devices in vehicles require high attention and precision to operate multiple buttons, which can be distracting for drivers and inefficient for users.
Innovation Solution
A method and input device that utilize marking and selection gestures to enable the detection of multiple switching elements with a single operator action, using a touch-sensitive surface to assign gestures to switching elements, allowing for easy and reliable input detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple buttons are used to control different functions, then the device functionality is improved, but the operating complexity and driver distraction increase
Solution Approach 1:
Multiple switching elements are merged into a single continuous touch-sensitive surface, allowing multiple functions to be controlled through a unified interface. The surface detects different touch positions and gestures to activate various functions without requiring separate physical buttons.
Solution Approach 2:
The interface transitions from discrete one-dimensional button presses to a two-dimensional touch surface where position, duration, and gesture type provide additional control dimensions. This allows multiple functions to be accessed through spatial variation rather than requiring multiple separate controls.
2Measurement precision
If multiple buttons are pressed to achieve a specific configuration, then the control precision is improved, but the time required and driver distraction increase
Solution Approach 1:
The touch-sensitive surface pre-defines multiple switching elements at specific positions, allowing the system to anticipate and prepare for different control options. When a user touches the surface, the system can detect the intended control element in advance through position detection, reducing the time needed for precise control.
Solution Approach 2:
The system enables continuous touch gestures where users can slide their finger across the surface to select multiple functions in sequence without lifting their finger. This maintains continuous contact and reduces the time required compared to repeated discrete button presses.
3Productivity
If a single operating action is used to select multiple switching elements, then the productivity is improved, but the selection precision may be reduced
Solution Approach 1:
The system provides visual feedback by highlighting or indicating which switching elements are currently selected during a gesture. This allows users to monitor their selection in real-time and make adjustments, maintaining precision even when selecting multiple elements through a single continuous gesture.

AI summary
The invention relates to a method for capturing a user input for an input apparatus having a plurality of switching elements (2.1, 2.2, 2.3, 2.4), in which an operating action having a marking gesture (8) and a selection gesture (9) is captured. In this case, at least one first switching element and one further switching element (2.1, 2.2, 2.3, 2.4) are marked in succession in a particular order on the basis of the marking gesture (8), wherein the first switching element (2.1, 2.2, 2.3, 2.4) is marked first and then the at least one further switching element (2.1, 2.2, 2.3, 2.4). The marked switching elements (2.1, 2.2, 2.3, 2.4) are selected in succession in the reverse order on the basis of the selection gesture (9). Control signals are generated and output on the basis of the selected switching elements (2.1, 2.2, 2.3, 2.4). The invention also relates to an input apparatus having a plurality of switching elements (2.1, 2.2, 2.3, 2.4), a control unit (3) and a capture unit (2) which can be used to capture an operating action having a marking gesture (8) and a selection gesture (9). In this case, at least one first switching element (2.1, 2.2, 2.3, 2.4) and one further switching element (2.1, 2.2, 2.3, 2.4) can be marked in succession in a particular order on the basis of the marking gesture (8), wherein the first switching element (2.1, 2.2, 2.3, 2.4) can be marked first and then the at least one further switching element (2.1, 2.2, 2.3, 2.4). The marked switching elements (2.1, 2.2, 2.3, 2.4) can be selected in succession in the reverse order on the basis of the selection gesture (9), and control signals can be generated and output on the basis of the selected switching elements (2.1, 2.2, 2.3, 2.4).
