Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices with communication and information processing functions, such as home appliances and vending machines, often lack user identification, making it difficult to associate and organize them effectively for personalized user experiences.
Innovation Solution
An information processing apparatus and method that acquires device logs from various devices to determine correlations based on user behavior, using a correlation determination unit and preset conditions to identify devices likely used by the same user, facilitating better organization and utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If devices are used by many and unspecified users without user identification, then device accessibility and usage flexibility are improved, but the ability to organize and utilize devices for personalized user experiences deteriorates
Solution Approach 1:
The patent introduces device logs as an intermediary to indirectly identify users. Instead of directly identifying users through login operations, the system captures behavioral patterns, operation sequences, and usage characteristics from device logs to infer user identity and preferences, thereby maintaining device accessibility while recovering user-specific information
Solution Approach 2:
The patent replaces the mechanical/login-based user identification system with an information-based system. Instead of relying on explicit user authentication mechanisms, the system uses automated analysis of device logs and behavioral data to substitute for traditional user identification, enabling personalized experiences without requiring direct user input
2Measurement precision
If device logs are collected and analyzed to determine user correlations, then the precision of device organization and personalization is improved, but the complexity of data processing and analysis increases
Solution Approach 1:
The patent segments the complex data processing task into distinct functional units: device log acquisition, state information extraction, correlation determination, and device organization. Each unit handles a specific aspect of the analysis, reducing overall system complexity while maintaining high measurement precision through specialized processing at each stage
Solution Approach 2:
The patent transforms raw device log data into meaningful correlation metrics by changing parameters from raw operational data to standardized state representations. This parameter transformation enables accurate device correlation determination while simplifying the processing complexity through normalized data formats and predefined correlation criteria
