Solution Overview
Problem
Current methods lack an objective and technical solution for monitoring social interactions to identify lonely individuals, particularly in nursing homes, leading to ineffective addressing of loneliness and its associated health issues.
Innovation Solution
A system and method that utilize proximity information from user devices to calculate social interaction patterns, generate social isolation scores, and determine loneliness risk, incorporating RF power-based distance estimation and statistical analysis to provide notifications for assistance or medical evaluations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If generalized approaches or subjective observational assessments are used to address loneliness, then implementation is simple, but effectiveness is poor
Solution Approach 1:
The patent replaces subjective observational assessments with automated electronic monitoring systems. User devices continuously collect proximity data through sensors, and a processing system automatically analyzes this data to generate social isolation scores, eliminating the need for manual caregiver observations and significantly improving reliability while maintaining manageable system complexity through automation.
Solution Approach 2:
The patent introduces an intermediary processing system that acts as a mediator between raw proximity data from user devices and the final loneliness assessment. This intermediary system processes proximity information, generates social interaction metrics, and produces objective social isolation scores, bridging the gap between simple data collection and effective loneliness identification.
2Measurement precision
If no technical solution is implemented for monitoring social interactions, then system complexity is low, but the ability to objectively identify lonely individuals is lacking
Solution Approach 1:
The patent implements a self-service monitoring system where user devices automatically collect their own proximity data without requiring external intervention. Each device continuously measures its distance from other devices and transmits this data to the processing system, enabling automated, objective monitoring of social interactions while minimizing the complexity of deployment and operation.
3Measurement precision
If proximity information from multiple user devices is collected and analyzed, then accuracy of loneliness identification improves, but data processing complexity increases
Solution Approach 1:
The patent segments the data processing task by having each user device independently calculate its own proximity metrics with other devices, then transmit only these processed metrics to the central system. This segmentation reduces the computational burden on any single device and simplifies the overall data processing complexity while maintaining high accuracy through collective analysis of multiple data sources.

AI summary
A method for monitoring the loneliness state of a subject includes receiving proximity information for a plurality of user devices and then generating a loneliness decision for subjects who use the devices based on the proximity information. In one case, the proximity information may be projected onto a lower dimensional space, distance values corresponding to the proximity information may be compared, and the user devices may be ranked based on the comparison. A user may then be determined to be lonely based on the ranking of the user devices. In other cases, clustering techniques may be applied relative to one or more centroids. Distances may then be calculated and compared for purposes of generating a loneliness decision. In other cases, resource information may be taken into consideration with distance information for generating a loneliness decision.
