Solution Overview

Problem

Current methods for visualizing mobile device location data struggle to effectively combine spatial and temporal information, making it difficult for investigators to determine when and where multiple users may have met, especially when dealing with large datasets and multiple users.

Innovation Solution

A system that provides a visual representation of spatio-temporal data using a geographical map and timeline charts, with visual indicators to identify points in time when users could have met, allowing investigators to easily correlate location and time data without manually sifting through raw data.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If multiple users' travel paths are displayed on a geographic map, then spatial information is visualized, but it becomes impossible to determine whether users met because temporal information is lost

Engineering Contradiction:
Improvetemporal informationVSAvoidability to determine user meetings
Core Design Contradiction:
Loss of informationVSEase of operation

Solution Approach 1:

The patent adds a temporal dimension to the spatial map visualization by incorporating time-axis indicators and temporal markers directly onto the geographic map. This allows the system to display both spatial location and temporal information simultaneously, enabling investigators to determine whether users were at the same location at the same time without losing either dimension of information.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Measurement precision

If manual analysis of raw location data is performed, then accurate temporal-spatial correlation can be achieved, but the process becomes extremely time-consuming and inefficient

Engineering Contradiction:
Improvetemporal-spatial correlation accuracyVSAvoidanalysis efficiency
Core Design Contradiction:
Measurement precisionVSProductivity

Solution Approach 1:

The patent creates visual representations (copies) of the raw location data in the form of annotated geographic maps with temporal indicators. Instead of requiring investigators to manually analyze raw data tables, the system generates visual copies that preserve the temporal-spatial relationships while making them immediately interpretable, thereby maintaining accuracy while dramatically improving analysis efficiency.

Inventive Principle:
Principle #26Copying

3Ease of manufacture

If travel paths of multiple users are shown on a map, then spatial movement is visualized, but paths crossing does not indicate user meetings because temporal data is not represented

Engineering Contradiction:
Improvevisual representation capabilityVSAvoidtemporal context
Core Design Contradiction:
Ease of manufactureVSLoss of information

Solution Approach 1:

The patent merges spatial visualization (geographic map with travel paths) and temporal visualization (time-axis indicators, temporal markers) into a single integrated display. This combination allows the system to show both where users traveled and when they were at specific locations, enabling accurate determination of user meetings while maintaining visual clarity.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

Provided are systems and methods for visualizing spatio-temporal data of a user location. In one example, the method may include receiving spatio-temporal movement information of a first user device associated with a first user, and receiving spatio-temporal movement information of a second user device associated with a second user, identifying a point in time when the first user and the second user could have met based on the received spatio-temporal movement information of the first and second user devices, outputting, via a user interface, a first timeline indicating movement of the first user device over time and a second timeline indicating movement of the second user device over time, and displaying a visual indicator with respect to the first and second timelines indicating the identified point in time when the first and second users could have met.
