Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face inconvenience when switching between IoT devices, as context information is not efficiently linked, requiring users to restart interactions from scratch, which hampers user-friendliness and efficiency.
Innovation Solution
An information processing system that detects user behavior and links context information between IoT devices, allowing seamless continuation of interactions by acquiring and transferring context data between devices based on user movement and sensor data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If context information is not linked between IoT devices, then each device operates independently, but user-friendliness deteriorates as users must restart interactions when switching devices
Solution Approach 1:
The patent introduces a context information management server as an intermediary that collects, stores, and distributes context information between multiple IoT devices. When a user switches devices, the new device queries the server for relevant context information, enabling seamless continuation of interactions without direct device-to-device communication.
Solution Approach 2:
The system performs preliminary actions by proactively transferring context information to devices that are likely to be used next. The context information management server monitors user behavior patterns and pre-loads context data to the anticipated target device, so that when the user switches, the context is already available without requiring real-time requests.
2Loss of information
If context information is transferred between all IoT devices, then continuity is improved, but system complexity and communication overhead increase
Solution Approach 1:
The patent segments the context information management function from the IoT devices themselves, placing it in a dedicated context information management server. This centralizes the complexity of tracking, storing, and distributing context information, while individual devices maintain simpler local contexts and only communicate with the server when needed, reducing overall system complexity.
Solution Approach 2:
The context information management server acts as an intermediary that handles all context information transfer operations between devices. Instead of implementing complex peer-to-peer context sharing protocols between all device pairs, the server mediates all context exchanges, simplifying the communication architecture and reducing the computational burden on individual IoT devices.
3Speed
If context information is stored locally on each device, then access speed is improved, but information sharing between devices becomes difficult
Solution Approach 1:
The context information management server serves as a centralized intermediary that maintains copies of context information from multiple devices. When a device needs context data, it quickly queries the server which provides immediate access. The server's centralized storage enables any device to access any other device's context information without requiring direct device-to-device connections, thus maintaining fast access while enabling universal sharing.
Solution Approach 2:
The patent merges the context information storage capabilities of multiple distributed devices into a single centralized repository on the context information management server. This consolidation allows all devices to access a unified context database, combining the advantages of local fast access (through server queries) with global information availability (through centralized storage), enabling seamless context sharing across the entire IoT ecosystem.

AI summary
[Object] To provide an information processing apparatus which can dramatically improve user-friendliness by detecting behavior of a user and linking data with each other in advance between equipment to be operated by the user. [Solution] Provided is the information processing apparatus including a control unit configured to perform control to detect leaving of a user from the information processing apparatus and transmit at least part of context information exchanged with the user until then to another apparatus. According to the information processing apparatus, it is possible to dramatically improve user-friendliness through acquisition of context information.
