Remote Vehicle Control via Touch Force Variability Biometrics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote vehicle operation systems require continuous user input and two-hand operation to ensure safety, which can be disrupted by distractions, environmental conditions, and unintended changes in user device state, leading to potential vehicle control errors.
Innovation Solution
A system that uses a touch-sensitive user interface to detect random variations in user input forces over time, within predetermined thresholds, to infer user intent for vehicle control, incorporating an authentication module and wireless communication for secure and reliable remote operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If two-hand operation is required to ensure user intent, then safety is improved, but ease of operation deteriorates due to complexity and distraction requirements
Solution Approach 1:
The patent replaces the two-hand mechanical operation requirement with biometric authentication based on force variability analysis. The system measures the characteristic force patterns inherent in natural user interaction with the touch interface, extracting behavioral biometrics that uniquely identify the user's intent. This eliminates the need for complex two-hand operations while maintaining safety through authentic user verification.
Solution Approach 2:
The system utilizes the user's natural interaction patterns with the touch interface as the authentication mechanism. Instead of requiring the user to perform specific deliberate actions (like two-hand operation), the system passively measures and analyzes the inherent force variability characteristics of the user's natural input behavior, making the authentication process seamless and integrated into normal interaction.
2Reliability
If continuous communication is required between remote device and vehicle, then user intent verification is improved, but loss of time increases due to interruptions from calls and application changes
Solution Approach 1:
The patent implements preliminary authentication by capturing and analyzing force variability characteristics at the moment of user input initiation. The system extracts behavioral biometrics from the initial interaction pattern and uses this authentication to establish a trusted session, eliminating the need for continuous verification communications. This preliminary action ensures user intent is verified before the remote control session begins, preventing time loss from interruptions.
Solution Approach 2:
The patent replaces continuous communication verification with a single biometric authentication event. The force variability analysis captures the user's intent verification in one authentication moment, substituting the ongoing communication verification process. This eliminates time loss from interruptions while maintaining reliable user intent verification through the persistent authenticated session.
