Smart Alert Delivery Using Sensor State Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile device alert systems often fail to effectively renotify users, as secondary alerts are not guaranteed to capture the user's attention, especially when the device is inaccessible, leading to missed notifications.
Innovation Solution
Implementing smart heuristics that utilize sensors to determine opportune moments for sending alerts, suppressing or dismissing alerts based on device state changes, such as motion, light, and noise sensors, to ensure alerts are delivered when the user is likely to notice them.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a second alert is sent at a fixed time later, then the alert delivery time is extended, but the alert may still be missed if the device is inaccessible
Solution Approach 1:
The patent applies dynamics by transitioning from a fixed-time alert schedule to a dynamic alert delivery system that adapts to real-time device state changes. The system continuously monitors sensor data (motion, light, noise) and adjusts alert delivery timing based on detected state transitions, ensuring alerts are delivered when the device is accessible to the user rather than following a rigid timetable.
Solution Approach 2:
The patent implements feedback by using sensor measurements to monitor device state and adjust alert delivery accordingly. The system receives feedback from sensors about device accessibility, processes this information through a state engine, and modifies alert delivery timing based on this feedback, creating a closed-loop system that improves reliability.
2Measurement precision
If sensor measurements are continuously monitored, then the accuracy of device state detection is improved, but energy consumption increases
Solution Approach 1:
The patent applies periodic action by implementing continuous monitoring at discrete time intervals rather than truly continuous monitoring. The system periodically samples sensor data at predetermined intervals, which maintains adequate measurement precision for detecting state changes while significantly reducing energy consumption compared to continuous monitoring.
Solution Approach 2:
The patent uses partial action by monitoring only the necessary sensor data required for state detection rather than all possible sensor outputs. The system selectively processes sensor measurements that are relevant to determining device accessibility, reducing computational energy consumption while maintaining detection accuracy.
3Reliability
If multiple sensors are used to determine device state, then the reliability of accessibility determination is improved, but device complexity increases
Solution Approach 1:
The patent applies universality by using a multi-functional state engine that handles multiple tasks: processing sensor data from various sensors, determining device state, detecting state transitions, and controlling alert delivery. This centralized approach consolidates complexity into a single manageable component rather than requiring separate systems for each function.
Solution Approach 2:
The patent merges the functionality of multiple sensors and processing systems into a unified state detection and alert delivery system. By combining sensor inputs, state determination, and alert control in an integrated architecture, the system manages the complexity of multiple sensors through cohesive design rather than treating them as separate complex subsystems.

AI summary
Measurements can be obtained from sensors to determine a state of a device. The state can be used to determine whether to provide an alert. For example, after a first alert is provided, it can be determined that the device is not accessible to the user based on the determined state, and a second alert can be suppressed at a specified time after providing the first alert. The sensor measurements can be monitored after suppressing the second alert, and a state engine can detect a change in a state based on subsequent sensor measurements. If the state change indicates that the device is accessible to the user the second alert can be provided to the user. Alerts can be dismissed based on a change in state. A first device can coordinate alerts sent to or to be provided by a second device by suppressing or dismissing such alerts.
