Spatiotemporal Data Visualization with Dynamic Hierarchical Filtering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Video display systems face challenges in effectively presenting large amounts of spatiotemporal data to users, particularly in time-critical surveillance scenarios, where users need assistance to filter and focus on relevant information.
Innovation Solution
A system and method for graphical representation of spatial data, featuring a pie chart and a map, where the pie chart dynamically represents organizational breakdowns and the map dynamically represents geographic regions, with superimposed bar charts showing organizational members by location, allowing users to select and highlight specific data segments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If large amounts of spatiotemporal data are presented to users, then data completeness is improved, but user ability to focus on relevant information deteriorates
Solution Approach 1:
The display system divides spatiotemporal data into multiple hierarchical levels of granularity, allowing users to view data at different levels of detail. The system segments data representations to show both comprehensive views and focused details simultaneously, resolving the contradiction between data completeness and ease of focusing on relevant information.
Solution Approach 2:
The system adds temporal and hierarchical dimensions to data presentation, enabling users to navigate through different time windows and levels of data aggregation. This multi-dimensional approach allows comprehensive data to be presented while maintaining the ability to focus on specific relevant portions through temporal and hierarchical filtering.
2Measurement precision
If detailed spatiotemporal data is displayed, then measurement precision is improved, but information overload increases
Solution Approach 1:
The display system dynamically adjusts data representation based on user interactions and selected time windows. Data detail levels are dynamically modified to show precise information when needed while automatically reducing detail in other areas, preventing information overload while maintaining measurement precision where required.
Solution Approach 2:
Different regions of the display present data at different levels of detail, with high precision shown locally for selected or relevant data points while other areas show aggregated or summarized information. This local quality approach maintains measurement precision for critical data without causing overall information overload.
3Reliability
If comprehensive data representation is provided, then data accuracy is improved, but processing complexity increases
Solution Approach 1:
The system performs preliminary processing and organization of spatiotemporal data before presentation, pre-aggregating and structuring data according to multiple hierarchical levels. This preliminary action reduces processing complexity during user interaction while maintaining data accuracy through pre-computed representations at different granularities.

AI summary
A system and method for graphical representation of spatial data. A disclosed video display system is capable of presenting a layout of graphics objects as part of a displayed image. The system provides in the displayed image i) a first graphical representation in a first display area of a display and ii) a diagrammatic representation in a second display area. The diagrammatic representation features superimposed graphical elements that are dependent on the first graphical representation. The video display system can provide, for example, a pie chart as the first graphical representation and a map of a geographic area as the diagrammatic representation. The pie chart graphically represents, for example, a breakdown of members by organization, wherein each slice in the pie chart corresponds to a different organization. Superimposed on the map are elements of a bar chart, which is another example of a graphical representation.
