In-Cabin Display Arbitration for Multi-Switch Information Overload
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle display systems overwhelm occupants with information when multiple switches are operated simultaneously, leading to confusion and incorrect recognition of displayed information.
Innovation Solution
A display control device that includes a processor to detect contacts or movements near multiple operating portions within a vehicle cabin, arbitrating the display of information based on priority levels and positional relationships to ensure clear and relevant information presentation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If information corresponding to each of multiple operated switches is displayed on the screen, then complete information is provided to the occupant, but the occupant experiences information overload and fails to correctly recognize the information
Solution Approach 1:
The patent segments the displayed information by creating distinct visual regions for different switch operations. When multiple switches are operated simultaneously, the display is divided into separate areas, each showing information for a specific switch, allowing the occupant to process information in organized portions rather than as an overwhelming mass of data
Solution Approach 2:
The patent applies local quality by providing different display characteristics for different regions of the screen based on which switches are operated. Each region can have customized information presentation tailored to the specific switch operation, enabling the occupant to quickly identify and process relevant information from the appropriate local area rather than searching through uniform information across the entire display
2Adaptability or versatility
If multiple switches are operated simultaneously with equal priority, then all operations are recognized, but the display becomes confusing and difficult to interpret
Solution Approach 1:
The patent establishes priority levels for different switch operations in advance, before any actual switching occurs. This preliminary arrangement of priority information allows the display control device to automatically resolve conflicts when multiple switches are operated simultaneously, presenting information in a predetermined logical order that reduces confusion and simplifies the display structure
Solution Approach 2:
The patent implements dynamic information presentation where the display automatically adjusts its content and structure based on which switches are currently being operated. The system dynamically determines which information to display and in what format, transforming from a static display to an adaptive interface that responds to the specific combination of active switches, thereby managing complexity while maintaining versatility

AI summary
A display control device that includes: a memory; and a processor that is coupled to the memory, the processor being configured to in a case in which a contact with, or a movement adjacent to, any of a plurality of operating portions provided inside a vehicle cabin is detected, display information corresponding to that operating portion on a display portion inside the vehicle cabin, and, in a case in which a contact with, or a movement adjacent to, two or more of the operating portions is detected, arbitrate the displaying of information on the display portion.
