Vehicle Touch Interface With Segmented Areas For Incremental Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle operating devices for adjusting parameters like air conditioning settings require continuous and precise input, which can distract drivers and pose safety risks due to the high demands on cognitive and motor skills.
Innovation Solution
The operating device features a touch-sensitive surface with separate areas that allow incremental parameter changes through simple touches or swipe gestures, enabling intuitive and step-based adjustments without the need for exact positioning, allowing drivers to operate without continuous attention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If continuous and precise input is required for adjusting parameters, then parameter adjustment precision is improved, but driver distraction and safety risks increase
Solution Approach 1:
The touch-sensitive surface is divided into multiple separate areas (first area, second area, third area) with different functions. Each area responds to specific input patterns (single touch, double touch, swipe gestures) to provide discrete incremental adjustments rather than requiring continuous precise input, thereby reducing driver cognitive load while maintaining adequate parameter control precision
Solution Approach 2:
The system provides periodic incremental adjustments of parameters based on detected touch patterns. Instead of requiring continuous precise manipulation, the system advances parameters in discrete steps through periodic response to simplified driver inputs, reducing the complexity and distraction of the operating process while maintaining sufficient adjustment precision
2Ease of operation
If multiple separate areas are formed in the touch-sensitive surface, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The touch-sensitive surface uses a single unified sensing layer that detects multiple types of inputs (single touch, double touch, swipe gestures) across different areas. This multi-functional approach provides intuitive operation for driver-specific functions (volume, temperature) while maintaining a relatively simple overall device structure, avoiding the need for separate physical controls for each function

AI summary
The present invention relates to an operating device (10), particularly in a vehicle, comprising an operating element (1) having a touch-sensitive surface (2), and a control device (6) coupled to the operating element (1) so that data on touches of the touch-sensitive surface (2) can be transmitted to the control device (6). The operating device according to the invention is characterized in that at least two separate surfaces (5-1, 5-2) are formed within the touch-sensitive surface (2), and the control device (6) is configured such that a parameter is incrementally changed when it is detected that one of the at least two separate surfaces (5-1, 5-2) has been touched, and the same parameter is incrementally changed when it is detected that a swipe gesture has been performed on the touch-sensitive surface.
