Vehicle Display Control for Manager-Emphasized Safety Information
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for guiding drivers on safety and energy-saving driving practices through websites and applications are ineffective in ensuring that managers' emphasized information is adequately viewed by drivers, as browsing habits reveal discrepancies in page frequency between managers and drivers.
Innovation Solution
A display control device and method that acquires browsing history to identify specific display elements with significant differences in viewing frequency between managers and drivers, altering their display form, position, or decoration to draw attention to emphasized information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If standard display forms are used for all guidance pages, then the display system remains simple and consistent, but drivers do not pay sufficient attention to manager-emphasized information
Solution Approach 1:
The patent applies local quality by differentiating display forms based on the specific information being presented. Manager-emphasized pages receive special display treatment (different colors, positions, or formats) while other pages use standard display forms. This selective differentiation ensures critical information stands out without requiring complete system redesign.
Solution Approach 2:
The patent utilizes color changes as a visual differentiation mechanism. Pages emphasized by managers are displayed with distinct color schemes or highlights compared to standard pages. This visual cue immediately draws driver attention to important guidance information without adding complex control mechanisms.
2Loss of information
If all pages are displayed with the same prominence, then the display system remains simple to operate, but drivers cannot distinguish manager-emphasized information from other content
Solution Approach 1:
The patent introduces an additional visual dimension for information hierarchy. Beyond the standard content display, it adds visual attributes (color, position, size) as another dimension to differentiate importance levels. This allows drivers to quickly identify emphasized information without complicating the basic display operation.
Solution Approach 2:
The system performs preliminary action by pre-identifying and marking manager-emphasized pages before drivers view them. The display control device automatically applies special display forms to predetermined important pages, so drivers encounter highlighted information immediately without needing to search or navigate differently.
3Reliability
If drivers browse pages at their own pace without guidance, then browsing freedom is maintained, but critical safety and energy-saving information may be overlooked
Solution Approach 1:
The patent implements feedback by monitoring which pages drivers actually view versus which pages managers emphasize. This browsing history data feeds back into the system to refine display strategies, ensuring that critical information receives appropriate visual emphasis while adapting to actual driver behavior patterns.

AI summary
A display control device includes an acquisition unit configured to acquire a browsing history including a record indicating that vehicle driving information corresponding to each of a plurality of display elements was displayed on the display unit of each of the driver of a vehicle and a manager who manages the driver, an identification unit configured to identify a specific element from among the display elements based on the difference between the number of browses by the driver and the number of browses by the manager that are recorded in the browsing history acquired by the acquisition unit, and a display control unit configured to cause the display unit of at least one of the driver and the manager to display the specific element with the display form of the specific element, identified by the identification unit, made different from the display form of the other display elements.
