Egocentric Display for Spatial Data Orientation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display technologies fail to effectively present multi-dimensional data relative to an ego center, particularly in aerospace and medical imaging applications, where pilots and medical professionals need to quickly assess and navigate complex spatial information around a central point.
Innovation Solution
The development of an egocentric display system that maps multi-dimensional data onto a frame of reference centered around an ego point, using concentric circles, fiducial line segments, and reference lines to represent spatial relationships and data points, allowing for intuitive visualization of objects' locations, speeds, and directions relative to the ego center.

Engineering Contradiction Analysis
1Loss of information
If traditional display technologies are used to present multi-dimensional data, then the display structure is simple, but the ability to effectively present spatial relationships relative to an ego center is insufficient
Solution Approach 1:
The patent transforms three-dimensional spatial data into a two-dimensional display by projecting objects onto a plane based on their angular relationships to an ego center. This dimensionality reduction technique preserves essential spatial information (azimuth and elevation angles) while adapting it to a flat display surface, resolving the contradiction between maintaining spatial fidelity and simplifying display structure.
Solution Approach 2:
The display is segmented into multiple concentric rings and angular sectors, each representing different spatial zones relative to the ego center. This segmentation allows complex multi-dimensional spatial data to be organized into discrete, manageable regions that can be easily visualized and interpreted, improving spatial information presentation without requiring a complex overall structure.
2Ease of operation
If complex spatial data is presented using conventional methods, then all data can be displayed, but the ease of operation and quick assessment by users is reduced
Solution Approach 1:
The patent uses color coding to represent different spatial zones, object types, or data categories within the egocentric display. By assigning specific colors to different angular sectors or distance ranges, users can quickly assess spatial relationships and object characteristics at a glance, improving ease of operation while preserving comprehensive spatial information through visual differentiation.

AI summary
An egocentric display that corresponds to a multidimensional frame of reference. The multidimensional frame of reference may include an ego center, a nadir below the ego center, and a zenith above the ego center. The egocentric display includes a center point, an inner concentric circle and an outer concentric circle. The center point represents the nadir. The inner concentric circle is centered about the center point and represents a horizon plane that is perpendicular to a zenith-nadir line that passes through the zenith, the ego center, and the nadir. The outer concentric circle that represents the zenith should have a radius larger that the inner concentric circle and should also be centered about the center point.
