Location-Based Reminder Delivery System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional reminder systems are inflexible and often fail to alert users when they are not in proximity to the device, leading to missed reminders, which can be critical for adherence to therapeutic regimes or other important tasks.
Innovation Solution
A system that uses a reminder datastore, processor, and locating mechanism to identify and output alerts through nearby devices based on user location, with optional ranking of devices for optimal alert effectiveness and adaptability, including consideration of user preferences and ambient conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional preset devices are used to provide reminders at preset times, then the reminder system is simple to implement, but the user may miss the reminder if not in proximity to the device
Solution Approach 1:
The reminder system dynamically determines the user's location at the reminder time and selects the nearest available reminder device, transforming the static preset location approach into a dynamic location-based selection process. This resolves the contradiction by adapting the reminder delivery location based on real-time user position data.
Solution Approach 2:
A server acts as an intermediary between the user device and multiple reminder devices. The server receives reminder requests, determines user location, identifies the nearest reminder device, and coordinates the reminder delivery. This intermediary enables reliable reminder delivery across multiple devices without requiring complex peer-to-peer communication between all components.
2Reliability
If multiple reminder devices are used to increase reminder recognition, then the likelihood of user recognition improves, but the device selection process becomes more complex
Solution Approach 1:
The system assigns different roles and capabilities to different reminder devices based on their characteristics and locations. Each device is selected based on its suitability for the specific user context (location, availability, device type), rather than using a uniform approach across all devices. This resolves the contradiction by optimizing device selection for each specific situation.
Solution Approach 2:
The system changes multiple parameters simultaneously when selecting reminder devices: location proximity, device availability status, device type (visual/audio/tactile), and user preferences. By evaluating and weighting multiple parameters, the system efficiently selects the most appropriate device without requiring complex manual configuration.
3Reliability
If the system adapts to individual user preferences and learns effective alert methods, then the reminder effectiveness improves, but the system complexity increases
Solution Approach 1:
The system incorporates feedback mechanisms where user responses to reminders (acknowledgment, dismissal, interaction type) are recorded and used to refine future reminder delivery. The server learns from user behavior patterns to optimize device selection and alert type preferences, resolving the contradiction by automatically adapting based on observed user responses rather than requiring manual programming.
Solution Approach 2:
The system automatically manages its own optimization by analyzing user response patterns and adjusting its reminder delivery strategy without external intervention. The server autonomously learns which devices and alert types work best for each user based on accumulated data, reducing the need for manual system configuration while improving effectiveness over time.
Data Source
AI summary
A system for providing a reminder to a user is provided that comprises a reminder datastore arranged to store reminder information relating to a task for the user to be reminded about, and a reminder processor arranged to determine a time at which the reminder is due, based on the reminder information. A locating mechanism is provided to obtain information relating to a location of the user, and an output mechanism is provided to output reminder alerts through one or more reminder devices. The reminder processor is arranged to obtain information relating to a location of the user for the time at which the reminder is due, from the locating mechanism, and to identify one of the one or more reminder devices in proximity to said location of the user, based on known locations of the one or more reminder devices. The output mechanism is arranged to output a reminder alert through the identified reminder device.
