Location-Based Appointment Reminder System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Calendar-based automatic reminding systems fail to consider the user's location and activity, leading to inappropriate or ineffective reminders, as they send reminders irrespective of the user's current situation, such as being on the way to the appointment or in a 'do not disturb' zone.
Innovation Solution
A method and apparatus that integrate calendar reminders with location-based services to determine the user's location and schedule reminders accordingly, using rules to decide whether to send, postpone, or cancel reminders based on the user's location, activity, and direction of travel, ensuring timely and relevant notifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If calendar-based automatic reminding systems send reminders at predetermined time intervals, then reminders are sent consistently, but reminders may be sent at inappropriate times when the user is unavailable or already en route
Solution Approach 1:
The system dynamically adjusts reminder delivery based on real-time user location and activity data. Instead of using fixed predetermined time intervals, the system continuously monitors user context (location, direction of travel, current activity) and adapts the reminder timing and delivery method accordingly, resolving the contradiction between consistent delivery and user convenience
Solution Approach 2:
The system implements feedback loops by continuously tracking user location and activity status, then using this information to determine whether to send, postpone, or cancel reminders. The system receives feedback from location services and activity detectors, processes this information, and adjusts reminder delivery decisions in real-time, ensuring reminders are sent only when appropriate
2Device complexity
If reminders are sent based solely on time intervals, then the system is simple to implement, but the reminder effectiveness is reduced due to lack of context awareness
Solution Approach 1:
The system merges calendar reminder functionality with location-based services and activity detection capabilities. By combining multiple data sources (calendar events, GPS location, direction of travel, current activity status) into a unified reminder delivery system, the patent achieves context-aware reminder effectiveness without requiring completely separate systems
Solution Approach 2:
The system performs multiple functions through a single integrated platform: it manages calendar events, tracks user location, monitors activity status, determines optimal reminder timing, and selects appropriate reminder delivery methods. This multi-functional approach enhances reminder effectiveness while maintaining reasonable system complexity
3Measurement precision
If the system monitors user location and activity continuously, then reminder timing is optimized, but energy consumption and processing requirements increase
Solution Approach 1:
The system applies partial monitoring by selectively activating location and activity tracking based on proximity to appointment times and user-defined parameters. Instead of continuous monitoring at maximum precision, the system adjusts the intensity of monitoring based on contextual needs, reducing energy consumption while maintaining sufficient accuracy for effective reminder delivery
Data Source
AI summary
An automatic appointment reminder system uses location and/or direction of travel of the reminder recipient relative to appointments to affect the time of sending of appointment reminders to the user, and thus enhances the user's ability to be on-time for appointments.
