Augmented Device Retrieval Assistance Using Time-Spatial Axis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for locating misplaced mobile electronic devices are limited by the device's network connectivity and power level, making it difficult to track devices that are unused for extended periods or have exhausted batteries.
Innovation Solution
The proposed solution involves a system and method for augmented device retrieval assistance (ADRA) that uses a time-spatial axis to visually represent possible positions of a device within a location. This system includes registering devices and location information, monitoring device positions, and generating location images that overlay the device's position on a floor plan or map, allowing users to retrieve misplaced devices based on historical and spatial data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If current tracking methods are used that depend on network connectivity, then real-time location tracking is improved, but the ability to track devices with exhausted batteries or extended unused periods deteriorates
Solution Approach 1:
The system performs preliminary actions by having ADRA clients continuously monitor and record device positions and network connection statuses before the device becomes unreachable. This historical data is stored in advance, enabling location retrieval even when the device battery is exhausted or the device is unused for extended periods. The monitoring occurs proactively while the device is still accessible, creating a data record that persists independently of the device's subsequent operational state.
2Loss of information
If multiple devices are monitored continuously, then location information availability is improved, but data storage requirements and system complexity increase
Solution Approach 1:
The system extracts only the essential monitoring data elements needed for location retrieval - specifically device position coordinates and network connection status timestamps - and stores them in a simplified ADRA data structure. This selective extraction approach maintains location information availability while reducing the complexity of the monitoring system by focusing only on critical data points rather than comprehensive device state monitoring.
Data Source
AI summary
One or more processors to add identification information of a device to an initialized augmented device retrieval assistance (ADRA) data structure. Received data from ADRA clients monitoring the device within a location includes a network connection status and a time-based position of the device. The ADRA clients dynamically update the ADRA data structure with the location, a current position of the device, and a timeframe of the data from the monitoring by the ADRA clients. A request for ADR assistance is received that includes an identification of a target device, the timeframe, and a location. Location images are generated that include a location layout or floor plan. A time-spatial axis is rendered and sent to an ADRA client and includes location images and target device position within the respective images associated with a specific timeframe on the time-spatial axis.
