Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display and control systems for motor vehicles fail to reliably manage simultaneous operations by multiple users from different viewing angles, leading to confusion and potential errors in assigning actuation actions to the correct user context.
Innovation Solution
The system provides graphical activation information on the display to indicate which user's actions are being recognized, using a touch-sensitive detection unit and high-frequency signal differentiation to assign actuation actions to the correct viewing angle range, and includes features like color-coding and virtual control elements to enhance user identification and intuitive operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a multi-view display device displays different representations for different viewing angle ranges, then information can be provided to multiple users simultaneously, but it becomes difficult to reliably assign actuation actions to the correct user context
Solution Approach 1:
The system displays graphical activation information on the display to provide visual feedback indicating which user's actions are being recognized. The detection unit provides feedback about the detected approach direction, and the system uses this feedback to confirm correct user identification and actuation action assignment to the appropriate viewing angle range
Solution Approach 2:
The detection unit acts as an intermediary between the users and the control system. It detects the approach direction of actuating elements and translates this physical information into contextual information that allows the system to correctly assign actuation actions to the appropriate user context and viewing angle range
2Ease of operation
If the detection unit uses capacitive sensors to detect user approach, then contactless detection is enabled, but the system cannot distinguish between multiple users approaching simultaneously from different angles
Solution Approach 1:
The system transitions from detecting only the presence of a user (capacitive sensing) to detecting the directional information of the approaching actuating element. By adding spatial dimension information about the approach direction, the system can distinguish between multiple users approaching from different angles while maintaining contactless operation
Solution Approach 2:
The detection unit serves as an intermediary that captures directional information about the approaching actuating element. This intermediary component enables the system to differentiate between multiple users based on their spatial approach patterns, enhancing user identification accuracy beyond simple capacitive detection
3Area of stationary object
If the same operating device is used by both driver and passenger, then installation space is optimized, but confusion arises when both users attempt to operate the device simultaneously
Solution Approach 1:
The system segments the control operations by detecting which user (driver or passenger) is approaching the operating device. Based on the detected approach direction, the system activates different control contexts and displays different representations, allowing simultaneous independent operation by multiple users on the same physical device
Solution Approach 2:
The system dynamically adapts its behavior based on real-time detection of user approach. The control context and displayed representation change dynamically according to which user is currently approaching the operating device, enabling seamless switching between different user modes without requiring separate physical devices
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution ensures reliable operation by clearly indicating active users and their assignable actions, allowing for simultaneous multi-user operation without confusion, even when multiple users approach the operating device from different angles.
Implementation Method 1
the detection unit comprises a plurality of sensor units, so that a position of an approaching actuating element can also be determined in space
Implementation Method 2
They consist, for example, of a dot matrix display designed as a liquid crystal cell, in front of which an optical element designed as a cylindrical lens raster is arranged

AI summary
The invention relates to a display device and operator system (2) for a motor vehicle (1) comprising a multi-view display device (3), with which at least two different representations (31, 32) that can be viewed from different viewing angle regions can be displayed, an operator panel (9) for recording user entries and a detection unit (16) that detects the approach of an actuation element (14, 15) towards the operator panel (9) and that assigns the actuation element (14, 15) to one of the viewing angle regions (5, 6), so that an actuation operation of the actuation element (14, 15), which is recorded by means of the operator panel (9) can likewise be assigned to one of the different viewing angle regions (5, 6). According to the invention, at least in the representation displayed for the viewing angle region (5, 6), to which a subsequent actuation of the operator panel (9) is assigned, activation information characterising said assignment is graphically displayed.
