Steering Wheel Hand Pressure Interaction for Vehicle Target Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current sight tracking technologies for vehicle users have precision issues when selecting objects outside the vehicle, increasing driver risk due to the need for prolonged gaze, which can impair driving safety.
Innovation Solution
An interaction method and apparatus that determine the holding position and pressure of a user's hands on a steering wheel to accurately identify a target relative position, allowing users to select objects without excessive burden or risk.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If sight tracking technology is used to determine the object the user wants to select, then the user can select objects outside the vehicle, but the precision of recognizing the object is low and requires prolonged gaze which increases driving risk
Solution Approach 1:
The patent introduces an intermediary device (the steering wheel with pressure sensors) to mediate between the user's intent and the system's object selection. Instead of relying on sight tracking, the user's hand pressure on the steering wheel serves as an intermediary signal that accurately indicates the desired object without requiring prolonged gaze, thus resolving the contradiction between recognition precision and driving safety
Solution Approach 2:
The patent replaces the optical sight tracking system with a mechanical sensing system (pressure sensors on the steering wheel). This substitution eliminates the need for prolonged visual tracking while maintaining or improving object selection precision, thereby resolving the contradiction by using a different physical principle that doesn't compromise driving safety
2Measurement precision
If sight tracking technology is used to improve object selection precision, then object recognition can be achieved, but the user burden increases due to the need for prolonged gaze
Solution Approach 1:
The system uses the user's natural driving action (holding the steering wheel) to automatically determine target position. The pressure sensors detect the user's hand position and pressure on the steering wheel, allowing the system to self-determine the desired object without requiring the user to perform additional actions or maintain prolonged gaze, thus eliminating the burden while maintaining precision
