Vehicle HMI Icon Layout Adaptation via Usage Pattern Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face burdensome adaptation to new vehicle human machine interface (HMI) layouts and functionalities with each vehicle redesign, requiring learning and familiarization with updated systems, especially when switching to a new vehicle model, and often struggle with customizing icon arrangements for improved usability.
Innovation Solution
A method and system that dynamically adjusts the vehicle HMI to user preferences by analyzing selection patterns of icons, including function, timestamp, and location, to rearrange icons for easier access, leveraging a server that recognizes user behavior and updates the interface based on usage patterns across various devices and vehicles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If vehicle HMI is updated with new layout and functions in redesigned models, then functionalities and appearance are improved, but user adaptation burden increases
Solution Approach 1:
The HMI layout dynamically adapts to user preferences by automatically detecting frequently selected icons and repositioning them to more accessible locations. The system monitors user interactions over time and adjusts the interface configuration without requiring manual intervention or relearning, thus maintaining versatility while improving ease of operation.
Solution Approach 2:
The HMI system performs self-adjustment by automatically analyzing user behavior patterns and reconfiguring the interface layout based on detected preferences. This eliminates the need for users to manually customize the interface or undergo extensive learning periods when transitioning to new vehicle models.
2Adaptability or versatility
If more functionalities are added to vehicle HMI, then user capabilities are enhanced, but interface complexity increases
Solution Approach 1:
The system applies different organizational principles to different regions of the interface based on user behavior. Frequently accessed functions are automatically positioned in prominent, easily accessible areas, while less frequently used functions remain in standard locations. This creates a personalized layout that optimizes for common operations without requiring complete reorganization of the entire interface.
Solution Approach 2:
The HMI interface is effectively segmented into priority levels based on user interaction patterns. The system identifies and separates frequently used icons from less frequently used ones, creating a visual and spatial hierarchy that reduces perceived complexity by highlighting only the most relevant functions at any given time.
3Ease of operation
If manual customization of icon arrangement is allowed, then user preference is accommodated, but operation time increases
Solution Approach 1:
The system performs preliminary analysis of user preferences by monitoring icon selection patterns during normal operation. Rather than requiring users to spend time manually customizing the interface, the system proactively detects preferences and automatically implements layout adjustments, saving users significant time and effort.
Solution Approach 2:
The HMI system continuously monitors user interactions with icons and uses this feedback to automatically adjust the interface layout. The system detects which icons are frequently selected and repositions them to more accessible locations, creating a continuous improvement loop that adapts to user preferences without requiring manual intervention.

AI summary
Aspects of the subject technology relate to a technique automatically adapting a vehicle HMI to a user preference. The HMI includes a touchscreen displaying selectable icons associated with functions. Every time the HMI detects a selection of a first icon by a user among the icons, the HMI sends to the server, first information on a first function associated with the first icon, when the first icon is selected, and where the HMI is located when the first icon is selected. The server analyzes the first information to recognize a pattern of behavior taken by the user in selecting the first icon, generating a first user preference. The HMI updates an arrangement of the icons on the touchscreen based on the first user preference. The first user preference includes parameters that includes a certain day of a week, a certain time of that day, and a location.
