Smart Device Swivel Control for Rapid In-Vehicle Function Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In vehicles with shared mobility concepts, the limited screen area of smart devices hinders quick access to essential functions like driving safety, requiring immediate control methods that do not divert the driver's gaze, as conventional voice recognition technologies are slow and impractical for immediate function control.
Innovation Solution
A vehicle control apparatus and method utilizing a swivel operation of a smart device mounted on a holder within the vehicle, where the device includes a connection link and flexible display, allowing physical manipulation to rapidly access and control vehicle functions without gaze diversion, by recognizing swivel information and changing the screen accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a smart device with limited screen area is used to control vehicle functions, then the device can be easily operated, but the user requires multiple steps to access control screens which slows down operation speed
Solution Approach 1:
The system pre-arranges control screens in a hierarchical structure based on vehicle functions. When a swivel operation is detected, the system proactively displays the relevant control screen without requiring the user to navigate through multiple menus, thus preparing the interface in advance for the user's intended action.
Solution Approach 2:
The control system dynamically changes the displayed screen based on the direction and magnitude of the swivel operation. As the user swivels the smart device, the system real-time updates the interface to show different vehicle function controls, making the operation speed comparable to physical button presses.
2Adaptability or versatility
If the driver manipulates the smart device to control vehicle functions, then various functions can be accessed, but the driver's gaze is dispersed which degrades driving stability
Solution Approach 1:
The system replaces traditional mechanical button presses with swivel-based gestures. The smart device detects the swivel operation through its motion sensors and translates it into control commands, allowing the driver to control vehicle functions using wrist movements without taking eyes off the road, thus maintaining driving stability while providing versatile function control.
3Stability of the object's composition
If voice recognition technology is used to control vehicle functions without dispersing driver's gaze, then driving stability is maintained, but the response time is slow which reduces immediacy
Solution Approach 1:
The system substitutes voice recognition with swivel gesture recognition. The smart device's motion sensors detect swivel operations in real-time, and the control unit immediately processes these gestures to change and display relevant vehicle function control screens. This mechanical gesture-based approach provides immediate response while keeping the driver's gaze on the road, overcoming the slow response time of voice recognition.
