Shoe Identification via Image Capture for Gait Sensor Association
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for acquiring information about a person's gait using sensors attached to shoes face challenges in identifying the specific shoes equipped with sensors, which hinders accurate data acquisition and analysis.
Innovation Solution
An information processing system that includes an identification unit to recognize unique information on shoes using captured images, and a setting unit to establish an association between the acquisition device and the module device attached to the shoes based on this information, allowing for the identification and communication with the correct sensor-equipped shoes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If sensors are attached to shoes for gait information acquisition, then gait data can be collected, but the system cannot identify which specific shoes are equipped with sensors
Solution Approach 1:
The patent applies the copying principle by creating a visual representation (image) of the shoe's identification information and displaying it on the shoe itself. The imaging unit captures this displayed image, and the identification unit processes it to retrieve the unique identification information. This copying approach allows the system to identify shoes without adding physical identifiers that would interfere with sensor functionality or shoe aesthetics.
Solution Approach 2:
The patent introduces an intermediary mechanism - the image display and capture system - that mediates between the shoe identification need and the sensor data collection system. The imaging unit acts as an intermediary to capture identification information, while the identification unit serves as an intermediary to process this information and link it to the sensor data, solving the identification problem without direct physical tagging of the shoes.
2Reliability
If unique identification information is displayed on shoes as images, then shoes can be identified accurately, but the system complexity increases due to additional imaging and processing requirements
Solution Approach 1:
The imaging unit and identification unit are designed to perform multiple functions: the imaging unit not only captures identification information but can also capture other visual data about the shoe, while the identification unit processes various types of visual information. This multi-functionality reduces the need for separate dedicated components, thereby managing system complexity while maintaining reliable identification.
Solution Approach 2:
The shoe essentially identifies itself by displaying its own identification information as an image. The system leverages the shoe's own characteristics (its displayed image) for identification rather than requiring external tagging or complex tracking mechanisms. This self-service approach simplifies the overall system architecture by eliminating the need for additional identification hardware attached to the shoes.

AI summary
An information processing system includes an identification unit configured to identify unique information on shoes using at least part of a captured image of the shoes, and a setting unit configured to set an association between an acquisition device configured to acquire the unique information and a module device attached to the shoes based on the unique information.
