Action Recognition Server for Mobile Power and Privacy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies for action recognition in mobile devices consume excessive power and may compromise user privacy by sharing detailed information unnecessarily.
Innovation Solution
An information processing device and system that includes a receiving unit, action recognition unit, and transmitting unit to selectively share action recognition information based on configured action recognition levels and correlation scores between users, optimizing power consumption and privacy control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If action recognition application is continuously activated to share user actions in real-time, then the action recognition accuracy and real-time sharing capability are improved, but the mobile terminal power consumption increases
Solution Approach 1:
The system activates action recognition periodically or event-driven rather than continuously. The server receives movement information at predetermined intervals and triggers action recognition only when new movement data is available, reducing unnecessary continuous processing while maintaining real-time sharing capability when actions occur.
Solution Approach 2:
The server acts as an intermediary between mobile terminals, centralizing the computationally intensive action recognition process. Mobile terminals only need to transmit raw movement information and receive results, avoiding the need for continuous local processing and reducing overall system power consumption.
2Measurement precision
If detailed movement information is transmitted to enable accurate action recognition, then the action recognition precision is improved, but the user privacy protection capability deteriorates
Solution Approach 1:
The system extracts only the essential movement information needed for action recognition from complete raw data. By transmitting processed movement information rather than all sensor data, the system maintains recognition precision while removing unnecessary personal information that could compromise privacy.
Solution Approach 2:
The system applies different levels of information detail to different users based on their relationships. Movement information is shared with varying degrees of detail depending on the user group or individual recipient, allowing precise action recognition for authorized users while protecting privacy from unauthorized or less trusted parties.
3Loss of information
If comprehensive action information is shared with all users, then the information completeness is improved, but the information redundancy for recipients increases
Solution Approach 1:
The system customizes the level of action information shared with each user or user group. Different recipients receive different levels of detail appropriate to their relationship with the action performer, eliminating redundancy while maintaining completeness for each specific recipient.
Solution Approach 2:
The system provides partial action information to most users while reserving complete information for authorized users only. This approach ensures that the majority of users receive sufficient information for contextual awareness without being overwhelmed by redundant detailed data.

AI summary
There is provided an information processing device including a receiving unit that receives predetermined information from a first information terminal possessed by a first user and a second information terminal possessed by a second user, an action recognition unit that recognizes an action of the first user on the basis of the predetermined information received from the first information terminal, and an information transmitting unit that transmits, on the basis of the recognized action of the first user, information for determining whether or not the second information terminal possessed by the second user is to acquire the predetermined information.
