Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Presence-aware information systems face challenges in identifying and interacting with nearby devices and users effectively, leading to inefficient content delivery and communication.
Innovation Solution
A presence-aware information system that identifies connected devices and nearby users, utilizing sensors and user profiles to determine appropriate communication and content delivery based on user and device information, allowing for targeted content distribution and privacy management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the PAIS identifies and communicates with multiple nearby devices, then content delivery accuracy improves, but system complexity increases
Solution Approach 1:
The patent introduces a presence-aware information system as an intermediary layer between content sources and multiple devices. This mediator identifies nearby devices, determines communication targets based on user and device information, and manages content delivery routing, thereby improving delivery accuracy while centralizing complexity management.
Solution Approach 2:
The system implements feedback mechanisms by continuously identifying nearby devices, monitoring user presence, and adjusting communication targets dynamically. This feedback loop enables accurate content delivery to the appropriate device while adapting to changing environmental conditions and user preferences.
2Adaptability or versatility
If the PAIS monitors user presence and nearby devices continuously, then content delivery personalization improves, but energy consumption increases
Solution Approach 1:
The system employs periodic monitoring of user presence and nearby devices rather than continuous monitoring. By checking for presence changes at intervals and triggering content delivery updates only when necessary, the system maintains personalization capabilities while significantly reducing energy consumption compared to continuous monitoring.
3Ease of operation
If the PAIS delivers content to multiple devices simultaneously, then user experience improves, but loss of information increases
Solution Approach 1:
The patent applies local quality by delivering different content or different portions of content to different devices based on their specific characteristics, user presence, and privacy settings. Each device receives customized content appropriate to its context, improving user experience while preventing unauthorized access to sensitive information through device-specific content delivery.

AI summary
A presence-aware information system (PAIS) can identify a user interacting with an end-user device, such as a computer, and can identify a device that is connected to the PAIS nearby the user. Additionally, the PAIS can identify the user and other people nearby the user. Using this information, the PAIS can act, such as provide content, accordingly.
