Vehicle Touch Control System with Remote Visual Guidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle control systems require drivers to take their eyes off the road to operate touch screens, posing a safety risk due to the need for precise button presses, which can lead to brief but potentially hazardous distractions during driving.
Innovation Solution
A control system that displays active areas on a remote screen within the driver's field of vision, allowing users to control vehicle functions via touch gestures on a control touch screen without needing to look away, using a computation module to generate display and guidance data to indicate the correct touch location on the control touch screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the touch screen is located on the side of the driver's seat, then the user can control vehicle functions by touch, but the driver must take eyes off the road to press the screen precisely
Solution Approach 1:
The patent introduces a spatial dimension solution by placing a remote screen in the driver's direct field of vision (on the dashboard or windshield) rather than on the side. This dimensional relocation allows the display to be viewed without head movement, while touch gestures on the control touch screen remain simple and intuitive, resolving the contradiction between ease of operation and driving safety.
Solution Approach 2:
The patent introduces guidance data as an intermediary element that mediates between the driver and the control interface. The guidance data (arrows, icons, animations) displayed on the remote screen serve as visual mediators that guide the driver's finger movements on the control touch screen without requiring the driver to look at the screen location, thus maintaining both ease of operation and safety.
2Reliability
If the active areas are displayed on a remote screen in the driver's field of vision, then the driver does not need to take eyes off the road, but the driver must perform precise touch gestures on the control touch screen
Solution Approach 1:
The patent implements feedback by displaying guidance data on the remote screen that provides real-time visual guidance for touch gestures. The guidance data (arrows indicating direction, icons representing functions, animations showing expected gestures) gives the driver immediate feedback about what gesture to perform and where to touch, making precise control intuitive and easy without requiring visual attention to the screen location.
3Reliability
If guidance data are displayed to indicate touch direction, then the user can perform gestures without looking at the screen, but the system complexity increases
Solution Approach 1:
The computation module serves multiple functions: it generates display data for the remote screen, processes touch gestures from the control touch screen, generates guidance data based on gesture analysis, and communicates with vehicle equipment. This multi-functionality consolidates the system complexity into a single versatile module rather than requiring separate dedicated components for each function.
Data Source
AI summary
A control system installed aboard a vehicle and configured to allow the user to control, by performing a touch gesture on a control touch screen, a function of the equipment of the vehicle. The control system includes a computation module, the control touch screen and a remote screen that is configured to display display data corresponding to said function in the user's field of vision. The control touch screen is configured to generate instruction data associated with a control area on which the user performs the touch gesture on the basis of the display data displayed by the remote screen. The computation module is configured to generate the display data; to determine, on the basis of the instruction data, the function controlled by the user; and to communicate with the equipment of the vehicle so that the equipment activates the function controlled by the user.
