Adaptive Notification System Using Presence Sensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information notification systems in IoT environments often fail to provide notifications in an appropriate form to users, leading to inadequate recognition of notifications, especially when users are away from the source device.
Innovation Solution
An information notification system that uses a network of connected devices and servers to sense user presence and adaptively present notification information via another apparatus, such as a smart speaker or display, in a form that is appropriate for the user's location and behavior.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If notification is provided using a simple presence sensing method, then the notification can be delivered to the user, but the notification form may not be appropriate for the user's location and behavior, leading to inadequate recognition
Solution Approach 1:
The notification system dynamically adapts the notification form based on real-time user behavior and location data. The server selects from multiple notification forms (visual, auditory, tactile) and adjusts parameters such as notification intensity, repetition rate, and modality based on the user's current state, making the system flexible and context-aware rather than static
Solution Approach 2:
The system changes multiple parameters of the notification including the type of notification device used, the form of notification presentation, the timing of notification delivery, and the intensity of notification based on user behavior patterns and location information, thereby optimizing notification effectiveness for different contexts
2Ease of operation
If notification information is presented via another apparatus, then users away from the source device can receive notifications, but the notification may not be in an appropriate form for the user's current context
Solution Approach 1:
The server acts as an intermediary that receives notification information from the source device, processes it with user context data, selects the appropriate notification form, and delivers it through a second apparatus. This intermediary layer enables the system to adapt notifications to user context while maintaining accessibility for users away from the source device
Solution Approach 2:
The system uses user behavior information and location data as feedback to continuously optimize notification delivery. By monitoring user responses and contextual changes, the server adjusts notification parameters to improve recognition effectiveness while maintaining ease of access for remote users

AI summary
An information notification system (1) includes a plurality of apparatuses and first server (60). The apparatuses include a first device (10). Each of at least one of the apparatuses includes a sensor unit that senses whether any person is present and generates a presence-absence signal including person presence-absence information. A first device (10) includes a generator (11) that generates a notification signal including notification information that is to be provided to the user who uses a first device (10). A first server (60) includes an information acquirer (61) that acquires the person presence-absence information, and a presentation controller (66) that determines a presumed position and causes a second device (20) to present the notification information, the presumed position being the position of a person presumed based on the person presence-absence information, and the second device being one of one or more apparatuses that are capable of presenting the notification information to the person who is in the presumed position among the apparatuses. A presentation controller (66) changes a form of presentation in accordance with presentation setting information that is information about the person who is in the presumed position.
