Vehicle Control Device Gesture Recognition Virtual Space
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle control systems do not allow drivers to control devices inside a vehicle by gesture while keeping their eyes ahead, limiting convenience and safety, especially when passengers need to interact with multiple devices.
Innovation Solution
A vehicle control device that uses a camera and processor to create a virtual control space adjacent to the passenger, matching devices to this space based on the passenger's position and detecting preset gestures to control them, allowing voice recognition and noise cancellation for enhanced interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a driver controls devices inside a vehicle by traditional methods (buttons, touchscreens), then the driver must look away from the road, but this reduces driving safety
Solution Approach 1:
The patent replaces mechanical control interfaces (buttons, touchscreens requiring visual attention) with a gesture recognition system using cameras and image processing. The driver controls devices through hand gestures detected by the camera, eliminating the need to look at physical controls while maintaining intuitive operation.
Solution Approach 2:
The patent introduces a virtual control space as an intermediary between the driver and physical devices. This virtual space, projected or displayed in the driver's field of view, allows gesture-based interaction without requiring the driver to physically reach for or visually focus on traditional control interfaces.
2Ease of operation
If a virtual control space is created for gesture control, then device control convenience is improved, but the system complexity increases
Solution Approach 1:
The patent makes the camera system multi-functional by using it for both driver monitoring and gesture recognition. The same image processing capabilities serve multiple purposes: detecting driver presence, tracking gestures, and controlling devices, thereby reducing the need for separate specialized sensors and systems.
Solution Approach 2:
The system automatically detects the driver's gestures and intent without requiring explicit commands or system configuration. The gesture recognition algorithm autonomously interprets hand movements and translates them into device control actions, reducing the cognitive and operational burden on the driver.
3Adaptability or versatility
If multiple passengers are present in the vehicle, then the system must manage multiple users, but this increases the difficulty of detecting and measuring user intent
Solution Approach 1:
The patent divides the vehicle interior into multiple detection zones, each associated with a specific seat or passenger area. The system independently processes gestures within each zone and attributes them to the corresponding passenger, enabling simultaneous control by multiple users without cross-interference.
Solution Approach 2:
The patent applies different control priorities and recognition sensitivities to different passengers based on their positions. For example, the driver's gestures may have higher priority or different gesture sets compared to front or rear passengers, allowing customized interaction patterns for each user role.

AI summary
A vehicle control device is disclosed. The vehicle control device includes: an interface unit that is connected to a camera for capturing a vehicle passenger and to a plurality of devices installed inside the vehicle; and a processor that receives an image captured by the camera through the interface unit and exchanges information with the plurality of devices through the interface unit, wherein the processor detects the position of the passenger from the image acquired by the camera, configures a space adjacent to the passenger as a virtual control space, matches a device corresponding to the position of the passenger, among the plurality of devices, to the virtual control device, and, upon detecting a preset gesture through the virtual control space, controls the device based on the preset gesture.
