Touch Guidance Interface for Remote Vehicle Rotation Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote-parking systems lack intuitive and user-friendly guidance for vehicle movement control, particularly in terms of ease of viewing and operation.
Innovation Solution
An information terminal with a display that provides guidance images extending in a left-right direction, featuring a second guidance image at a user-instructed position, which serves as a starting point for specific operations like rotation and swiping, to control the movement of a vehicle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a first guidance image extending in a left-right direction is displayed to provide comprehensive movement guidance, then the guidance coverage is improved, but the operation complexity increases due to the need to switch to a second guidance image for specific operations
Solution Approach 1:
The first guidance image is displayed in advance to show the overall movement path and direction before the user performs the specific rotation operation. This preliminary visual guidance helps users understand the intended vehicle movement without requiring them to think about the complex rotation mechanics, thus reducing operational complexity while maintaining guidance completeness.
Solution Approach 2:
The second guidance image acts as an intermediary element that bridges the gap between the user's touch input and the vehicle's rotation movement. By displaying this intermediate guidance image at the touched position on the first guidance image, the system mediates the transformation from simple touch input to complex rotation control, making the operation easier while preserving the ability to convey comprehensive movement information.
2Measurement precision
If a second guidance image with shorter length is displayed at user-instructed positions for rotation control, then the rotation precision is improved, but the device complexity increases due to managing multiple guidance images
Solution Approach 1:
The guidance system is segmented into two distinct functional components: the first guidance image that extends in the left-right direction to show overall movement direction, and the second guidance image with shorter length that appears at user-touched positions to indicate rotation control. This segmentation allows each image to specialize in a specific control function, improving rotation precision while managing complexity through clear functional separation rather than requiring a single complex image to handle all control aspects.

AI summary
An information terminal carried by a user of a moving object includes: a display configured to perform a position instruction operation on a display image; and a controller configured to perform movement control of the moving object based on a specific operation including a rotation instruction operation of the user on the display. After the controller causes the display to display a first guidance image that extends in a left-right direction, the controller causes the display to display, at a first position instructed by the user on the first guidance image, a second guidance image that has a length in a left-right direction shorter than that of the first guidance image and that serves as a starting point of the specific operation.
