Activity-Based Reminder Triggering via Sensor Fusion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing reminder devices are limited in effectively preventing the loss of important personal items as they rely on fixed time schedules or location-based triggers, which do not account for varying activities and events that require timely reminders when transitioning between different locations.
Innovation Solution
A reminder message device equipped with sensors and detectors that anticipate and detect specific activities, such as entering a car, preparing to leave a destination, or accelerating to a certain speed, to deliver reminders through audio, text, or voice messages, ensuring timely reminders regardless of location.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If reminder devices use fixed time schedules to deliver reminder messages, then the device structure is simple, but the reminder timing is not timely when activities occur at varying times
Solution Approach 1:
The system transitions from static fixed-time scheduling to dynamic activity-based triggering. Sensors continuously monitor user activities (walking, driving, entering locations) and dynamically determine when to deliver reminders, ensuring timely delivery regardless of predetermined schedules.
Solution Approach 2:
The patent replaces the mechanical time-based triggering mechanism with sensor-based activity detection. Instead of relying on clock-based intervals, the system uses accelerometers, GPS, and other sensors to detect user activities and automatically trigger appropriate reminders.
2Adaptability or versatility
If reminder devices use location-based triggers, then the reminder can be context-aware, but the device cannot effectively handle varying geo-spatial imagery and different types of places
Solution Approach 1:
The system employs multiple sensor types (accelerometers, GPS, magnetometers, barometers) that can detect various activities across different contexts. This multi-functional sensing approach allows the same device to handle diverse scenarios whether indoors or outdoors, at different locations, or during various activities without requiring location-specific customization.
Solution Approach 2:
The system changes from relying on absolute location parameters to detecting relative activity parameters. By monitoring acceleration patterns, movement speed, direction changes, and other activity-based parameters, the system can trigger appropriate reminders regardless of the specific geo-spatial context, making it universally applicable across different types of places.
3Reliability
If reminder devices detect specific activities like entering a car or accelerating, then timely reminders can be delivered, but the device requires multiple sensors and detectors
Solution Approach 1:
The patent combines multiple sensor functions into an integrated activity detection system. The accelerometer, GPS, magnetometer, and barometer work together as a unified sensing platform, where data from multiple sensors is processed collectively to recognize activities such as driving, walking, or entering locations, reducing the need for separate dedicated sensors for each function.
Solution Approach 2:
The system uses the device's existing sensors (accelerometers, GPS receivers) that are already present in modern mobile devices for reminder triggering, rather than requiring additional specialized sensors. The device leverages its own built-in capabilities to perform activity detection and reminder delivery.
