Dynamic Feedback Range Adjustment for Obstruction Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies for detecting obstructions, such as the white cane, are inadequate in notifying users of relevant obstructions based on their specific situations, leading to inefficient detection and potential collisions.
Innovation Solution
An information processing apparatus that sets a feedback target range based on acquired input information, including user and environmental data, to provide appropriate notifications to users about potential obstructions, using sensors like distance measurement, acceleration, and geomagnetic sensors, and outputs this information to the user through vibration, audio, or visual means.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed detection range is used for all situations, then the system is simple to operate, but it cannot adapt to different user situations and may cause unnecessary warnings or missed detections
Solution Approach 1:
The patent implements dynamic adjustment of the feedback target range based on real-time detection of user movement state (walking, running, stationary) using acceleration sensors. The system automatically changes detection parameters according to the detected movement pattern, enabling adaptability without requiring complex manual configuration or user input.
Solution Approach 2:
The system performs self-adjustment by automatically detecting user movement state and setting appropriate feedback target ranges without external intervention. The acceleration sensor data is processed to determine movement patterns, and the system autonomously configures detection parameters, eliminating the need for manual setup or complex user interfaces.
2Reliability
If the feedback target range is set to cover all possible obstructions, then detection coverage is maximized, but unnecessary warnings increase and reduce information quality
Solution Approach 1:
The patent applies different feedback target range settings based on local conditions - specifically, adjusts detection parameters according to the detected movement state (walking, running, stationary). This allows the system to optimize detection accuracy for each specific situation rather than using a uniform setting, reducing unnecessary warnings while maintaining comprehensive coverage when needed.
3Ease of operation
If manual setting of feedback target range is required, then the system is simple, but ease of operation decreases and user burden increases
Solution Approach 1:
The system automatically detects user movement state through acceleration sensors and autonomously sets the feedback target range without requiring manual user input. The processing unit analyzes acceleration data to determine movement patterns and automatically configures appropriate detection parameters, significantly improving ease of operation while implementing intelligent automation.
