Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle user interfaces face limitations in expandability and usability due to physical buttons, complex touch displays, and the difficulty of learning and utilizing numerous voice commands, which can compromise safe driving.
Innovation Solution
A multi-modal user interface that combines gesture detection using a 3D camera with voice recognition to identify and operate vehicle controls, allowing drivers to designate manipulation targets through gestures and voice commands, ensuring accurate and efficient control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If physical buttons are used for vehicle controls, then the interface is simple and reliable, but the expandability is limited due to limited space
Solution Approach 1:
The patent replaces physical mechanical buttons with a gesture recognition system using a 3D camera. The gesture detector captures hand movements and translates them into control commands, eliminating the need for physical buttons while maintaining simple operation. This substitution enables unlimited expandability since software-based gestures can be programmed for any function without requiring additional physical space in the vehicle.
2Adaptability or versatility
If touch displays are used to increase control options, then expandability improves, but the number of screen transitions increases complicating the interface
Solution Approach 1:
The patent substitutes touch display interactions with gesture-based control. Instead of requiring drivers to navigate through multiple screen transitions and menu layers, the system directly maps gestures to control functions. For example, a pointing gesture combined with voice command can directly activate a function without intermediate screen transitions, maintaining simplicity while achieving high expandability.
Solution Approach 2:
The patent introduces voice recognition as an intermediary between the driver's intent and the vehicle's control system. The voice recognizer translates spoken commands into control signals, working in conjunction with gesture detection to eliminate the need for complex screen transitions. This intermediary layer allows direct access to functions while maintaining natural and simple operation.
3Adaptability or versatility
If many voice commands are provided for high expandability, then adaptability improves, but the difficulty of learning and utilizing commands increases
Solution Approach 1:
The patent merges gesture recognition with voice command processing into a unified control system. The gesture detector identifies the driver's intended target or function through hand movements, while the voice recognizer processes the verbal command. This combination allows the system to interpret intent more accurately with fewer commands needed, reducing learning difficulty while maintaining high expandability. The gesture component provides contextual information that reduces the need for verbose voice commands.

AI summary
A vehicle is provided and includes a gesture detector that detects a gesture of a driver to designate a manipulation target object and a voice recognizer that recognizes a voice command generated by the driver to operate the designated manipulation target object. A controller is configured to transmit a control signal corresponding to the voice command to the manipulation target object, and to operate the manipulation target object to perform an operation corresponding to the voice command.
