Solution Overview
Problem
Interactive control devices in motor vehicle cockpits face challenges in balancing information representation and ease of operation, as conventional systems either obscure information with large control elements or require precise stylus use, which is difficult in a moving vehicle.
Innovation Solution
A method that adapts information representation on a display device based on user intention, using sensor information to optimize control element visibility and size for easy activation, switching between visual and haptic layouts to ensure high information density and comfortable operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If control elements are made large to improve ease of operation, then ease of operation is improved, but the display area available for information representation is reduced
Solution Approach 1:
The control device dynamically adapts the representation of control elements based on detected user intention. When a control intention is detected, the relevant control elements are enlarged or highlighted to facilitate easy activation. When no control intention is detected, the control elements return to their normal smaller size, maximizing the display area for information representation. This dynamic adjustment resolves the contradiction by providing large control elements only when needed for operation.
Solution Approach 2:
The system changes the visual parameters (size, brightness, contrast) of control elements based on the detected control intention. Upon detecting that a user intends to activate a specific control element, the system increases the size or visual prominence of that element to improve ease of operation. This parameter change is temporary and reversible, allowing the display area to be maximized during information display mode while providing enhanced operability during interaction mode.
2Area of stationary object
If control elements are made small to maximize display area, then display area is improved, but ease of operation is reduced
Solution Approach 1:
The control device employs dynamic adaptation where control elements maintain a small size during normal information display to maximize the display area. However, when a control intention is detected through sensor information analysis, the system dynamically enlarges or highlights the relevant control elements to improve ease of operation. This ensures that the display area is maximized during information presentation while providing easy operation when interaction is needed.
3Measurement precision
If multiple control operations are required to activate a control action, then precision of control is improved, but productivity is reduced
Solution Approach 1:
The system performs preliminary analysis of sensor information to detect user intention before the user actually activates a control element. By anticipating which control element the user intends to activate, the system can prepare the interface in advance, potentially pre-highlighting or pre-positioning control elements. This reduces the number of steps needed to complete a control action while maintaining precision, as the system is already prepared for the anticipated interaction.
Solution Approach 2:
The control device continuously monitors sensor information providing real-time feedback about user intention. This feedback loop allows the system to adapt the display and control element representation dynamically, reducing the number of operations needed. When the system detects a control intention, it can immediately adjust the interface to facilitate rapid activation, thereby improving productivity while maintaining control precision through continuous monitoring and adaptation.

AI summary
An interactive control device includes a display device, and a method is for operating the interactive control device. The method includes: displaying graphical information on the display device; receiving sensor information; activating a control action if on the basis of the sensor information it is ascertained that a body part of a user is located within an activation region that is spatially defined relative to a display region of a control element on the display device with which the control action is associated; the received sensor information including user information that is evaluated prior to an activation of the control action in order to ascertain a control intention for the at least one control element; and the information represented on the display device being adapted as a function of the ascertained control intention such that the at least one control element is represented in a manner optimized for the activation of the control action associated with the control element. The control device may be arranged as a component of a motor vehicle console so as to be able to implement the control method.
