Vehicle Control Interface for Button Identification Errors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In vehicle control systems, as the number of controllable components increases, users face difficulties in identifying corresponding command buttons, leading to a higher probability of operation errors due to the overwhelming number of buttons displayed on the screen.
Innovation Solution
A vehicle control apparatus that displays a vehicle image from a virtual viewpoint, allowing users to perform touch operations to change the view and enlarge or zoom in on specific areas, thereby reducing the number of visible buttons to only those relevant to the currently displayed portion of the vehicle, preventing operation errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the number of command buttons is increased to control more vehicle portions, then the control capability is improved, but the user's ability to identify buttons and grasp correspondence relations deteriorates
Solution Approach 1:
The display screen is segmented into multiple regions, with each region showing a portion of the vehicle image and associated command buttons. This allows the interface to be divided into manageable sections, enabling users to focus on one area at a time while maintaining access to comprehensive control capabilities.
Solution Approach 2:
The patent transitions from a one-dimensional linear arrangement of buttons to a two-dimensional spatial arrangement where buttons are positioned according to their corresponding locations on the vehicle image. This spatial mapping allows users to intuitively identify button functions based on their position relative to the vehicle portions they control.
2Adaptability or versatility
If all command buttons are displayed on one screen, then comprehensive control is achieved, but the user cannot grasp correspondence relations between vehicle portions and buttons
Solution Approach 1:
The vehicle image serves as an intermediary element that visually connects command buttons to their corresponding vehicle portions. By displaying buttons in proximity to their associated vehicle components within the image, the system provides an intuitive visual mediator that helps users understand the relationship between control elements and controlled objects.
Solution Approach 2:
The patent replaces traditional mechanical switch arrangements with a graphical user interface that uses visual display and spatial positioning to convey functional relationships. This substitution allows for more flexible information presentation and reduces the cognitive load required to understand button functions.
3Adaptability or versatility
If the number of command buttons displayed increases, then more vehicle portions can be controlled, but the probability of operation error increases
Solution Approach 1:
Different regions of the display screen have different functional qualities - some areas show vehicle images while others show command buttons. This local differentiation allows users to quickly identify and access the specific control functions they need without being overwhelmed by the entire set of controls, thereby improving operational accuracy.

AI summary
In a vehicle control apparatus, a display device displays a vehicle image showing a vehicle shape viewed from a virtual view point, and a user interface accepts a user's operation. When the user interface accepts the user's operation that issues an instruction for changing the vehicle image, a display control unit causes the display device to display the vehicle image after the changing of the virtual view point. Simultaneously, the display control unit causes the display device to display command buttons corresponding to portions of the vehicle shown by the vehicle image after the changing of the virtual view point.
