Vehicle Touch Display Input for Intuitive Sliding Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle input devices do not provide an intuitive and comfortable way for occupants to control on-board equipment, as information displayed is separate from the touch operation area, leading to confusion in understanding changing conditions of on-board equipment.
Innovation Solution
An input device with a display region in the vehicle cabin front portion and a touch sensor, where sliding operations on the image within the display region output signals to on-board equipment, allowing the image to move in accordance with the operation, enabling intuitive control of on-board equipment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If information is displayed in a separate region from the touch operation area, then the display can be provided at the instrument panel, but the occupant cannot intuitively understand changing conditions of on-board equipment
Solution Approach 1:
The patent combines the display region and touch sensor into a single integrated display region that serves both as information display and operation input area. This merging allows the image to be displayed and touched at the same location, enabling intuitive understanding of changing conditions while maintaining ease of operation through direct touch interaction.
Solution Approach 2:
The patent introduces an image as an intermediary element that moves in response to touch operations. This image serves as a visual mediator between the occupant's touch input and the on-board equipment's changing conditions, providing intuitive feedback about system state changes while maintaining simple touch-based operation.
2Ease of operation
If the display region is disposed at the instrument panel, then the structure is conventional, but the operability is reduced compared to a rear-side display
Solution Approach 1:
The patent moves the display region from the traditional instrument panel (front view) to the rear side of the steering handle (rear view dimension). This dimensional repositioning places the display in a more accessible location for the occupant's hand and finger, improving operability without significantly increasing overall system complexity.
3Ease of operation
If the display region is made accessible for operation, then operability is improved, but accidental operation by passenger side occupant may occur
Solution Approach 1:
The patent applies local quality by displaying different types of information in different regions of the display area. Frequently operated items are placed in the outer side region (easier to reach), while travel-related information is positioned in the inner side region (harder to accidentally touch). This spatial differentiation of information types reduces accidental operation while maintaining ease of operation for intended functions.
