Vehicle Control Terminal Using QR Code Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle input devices, such as physical user interfaces (PUIs) and graphical user interfaces (GUIs), face limitations in convenience and usability due to the need for separate devices for input and display, leading to user distraction, increased operation time, and higher manufacturing costs.
Innovation Solution
A terminal that uses QR code or NFC marks to recognize user inputs and transmit control signals to corresponding electronic devices in a vehicle, allowing for a unified interface that can be controlled via voice, gesture, or augmented reality, reducing the need for physical input devices and enhancing user interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a physical user interface (PUI) or graphical user interface (GUI) is used for vehicle control, then user input can be received, but the user's gaze is distracted when operating the input device and checking the display device located at different positions
Solution Approach 1:
The patent combines the input device and display device into a single integrated terminal device. The terminal includes both a display unit and an input unit (such as a touchscreen or gesture sensor) in one location, allowing users to both operate controls and view feedback without moving their gaze to separate components.
Solution Approach 2:
The patent introduces gesture recognition and spatial interaction as a new dimension of input beyond traditional physical buttons or touchscreen taps. By detecting hand gestures, body movements, or eye tracking in three-dimensional space, the system allows users to interact with the vehicle controls without direct manual contact, reducing the need to look down at control panels.
2Ease of operation
If a rotary input device is used to navigate to desired content icons, then operation can be performed without looking at the input device, but it takes a long operation time to reach the desired location
Solution Approach 1:
The system pre-loads and pre-displays frequently accessed functions and controls based on predicted user needs. By anticipating which controls the user will need next and preparing them in advance on the display, the system reduces the time required to navigate through menus and reach desired functions.
Solution Approach 2:
The user interface dynamically adapts its layout and content based on the current vehicle state, user preferences, and context. Frequently used controls are automatically positioned in more accessible locations, and the system learns from usage patterns to optimize navigation paths, reducing the time needed to reach desired functions.
3Adaptability or versatility
If hard keys, buttons, levers, or keypads are used to receive operation commands, then various functions can be controlled, but a large physical space is required and manufacturing cost increases due to additional components like LED lighting
Solution Approach 1:
The terminal device serves multiple functions in a single integrated unit: it displays vehicle information, receives user input through various modalities (touch, gesture, voice), provides haptic feedback, and controls multiple vehicle systems. This multi-functional approach eliminates the need for separate physical controls for each function, reducing overall device complexity.
Solution Approach 2:
The patent replaces traditional mechanical input devices (physical buttons, levers, and keypads requiring LED backlighting) with electronic and optical sensing systems. Gesture recognition cameras, ultrasonic sensors, or capacitive touch surfaces detect user input without requiring physical contact or additional lighting components, thereby reducing manufacturing complexity and cost.
