Vehicle Input Device Touch Screen Selection Marking Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing input devices for motor vehicles lack an efficient method for navigating through complex information displays, particularly in navigation systems, where selecting and confirming destinations on a touch screen is not intuitive and lacks haptic feedback.
Innovation Solution
An input device with a touch screen and integrated display that uses a control system to generate and displace a selection marking based on touch motions, providing haptic feedback through an actuator, allowing for intuitive navigation and destination selection with optical and tactile cues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a touch screen is used for inputting instructions in navigation systems, then the interface becomes more modern and space-saving, but the operation becomes less intuitive and lacks haptic feedback
Solution Approach 1:
The patent implements a haptic feedback mechanism where a selection marking (visual indicator) is displaced in response to touching motion across the touch screen. When the user drags their finger across the screen, the selection marking follows the motion trajectory, providing real-time visual feedback that enhances operational intuitiveness while maintaining the space-efficient touch screen interface.
2Ease of operation
If vibration elements are integrated directly into the functional plane for haptic feedback, then tactile feedback is provided, but the device complexity increases
Solution Approach 1:
The patent replaces complex mechanical haptic feedback systems with a software-based visual feedback mechanism. Instead of integrating vibration elements directly into the functional plane, the system uses a control system to generate and displace a selection marking on the display, substituting mechanical complexity with optical feedback that achieves the same user guidance objective.
3Measurement precision
If a selection marking is displaced according to touching motion, then destination selection becomes more precise, but the response time may increase
Solution Approach 1:
The patent implements preliminary action by continuously tracking and displacing the selection marking in real-time as the user's finger moves across the touch screen. The control system processes touching motion data and updates the selection marking position proactively during the dragging operation, ensuring precise destination selection without requiring additional processing time after the gesture is completed.

AI summary
An input device, e.g., for a motor vehicle, includes a display for displaying variable information, and a touch screen, disposed above the display, for inputting instructions by touching the touch screen, and the input device including a control system for generating a selection marking displayable on the display, and for displacing the selection marking displayed by the display according to a touching motion across the touch screen.
