Vehicle Operation System with Hand Detection and Pre-display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle operation systems require lengthy and inconvenient sequences for operators to access and control on-vehicle appliances, such as audio devices and navigation systems, due to the need to press touch panels and navigate through multiple menus.
Innovation Solution
An operation system that includes a touch panel, a camera to capture the operator's fingers, and a display section, with processors to determine the presence and number of fingers, and to display operation buttons or windows before they are touched, allowing for intuitive control and reducing the need for manual menu navigation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a touch panel with menu navigation is used to operate on-vehicle appliances, then the system can provide comprehensive control functions, but the operation time and sequence become lengthy and inconvenient
Solution Approach 1:
The system performs preliminary actions by detecting the operator's hand approach and pre-displaying the operation window and buttons before actual touch input is required. This allows the interface to be prepared in advance, eliminating the need for sequential menu navigation and significantly reducing operation time while maintaining comprehensive control functions
2Ease of operation
If traditional menu navigation is required to access operation buttons, then all functions can be organized systematically, but the operation load on the operator increases
Solution Approach 1:
The system provides self-service by automatically detecting the operator's intent through hand approach detection and dynamically generating the appropriate operation interface without requiring manual menu navigation. The system serves itself by preparing the correct operation window and buttons based on detected hand gestures, reducing operation load while maintaining systematic function organization
3Illumination intensity
If the operation interface is displayed only after touch input, then the display can be optimized for interaction, but the visibility and preparation time for the operator are reduced
Solution Approach 1:
The display section performs preliminary action by rendering the operation window and buttons visible before the operator completes the touch input sequence. The interface is prepared and displayed in advance based on hand detection, allowing the operator to see the available functions and prepare for interaction, thereby improving visibility and reducing reaction time

AI summary
The present invention provides an operation system for a vehicle capable of shortening an operation time, reducing an operation load, and improving visibility of a display section. The operation system includes an operation section on which a camera capturing a finger and a touch panel are installed, and a display section installed away from the operation section, and further includes a finger determination processor determining from an image captured by the camera whether or not an object approaching the operation section is a hand, a conversion processor converting a determination signal of the finger determination processor into a display instruction signal and outputting the converted result, and a pop-up processor displaying an operation button or an operation window on the display section before the hand is touched to the touch panel on the basis of the display instruction signal input from the conversion processor.
