Solution Overview
Problem
Existing augmented reality displays face challenges in efficiently displaying location-based points of interest, leading to screen clutter and reduced usability due to the lack of effective methods for optimizing the placement and visualization of these points.
Innovation Solution
The method involves preprocessing interface elements to determine their locations on a cylindrical surface, deriving three-dimensional coordinates, and using perspective grids to enhance depth perception, while adjusting display elements based on user input and sensor data to optimize visibility and interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If points of interest are displayed as graphical objects on the screen, then information about nearby points of interest is provided to the user, but screen clutter increases and display efficiency decreases
Solution Approach 1:
The patent applies dimensionality change by projecting points of interest from a two-dimensional screen space onto a three-dimensional cylindrical surface. This allows multiple POIs to be distributed in 3D space around the user, reducing overlap and clutter on the 2D display while preserving all information. The cylindrical projection creates a immersive, spatially-organized view where POIs are arranged according to their real-world angular and radial positions.
2Loss of information
If more points of interest are displayed on the screen, then more information is provided to the user, but the usability and interaction ease are reduced
Solution Approach 1:
The patent uses curvature by employing a cylindrical projection surface instead of a flat 2D plane. This curved surface naturally distributes points of interest in a spatial arrangement that mimics the user's real-world environment, making it easier to mentally map and interact with multiple POIs simultaneously. The curved display geometry provides intuitive spatial relationships that improve usability when displaying numerous points of interest.
3Productivity
If interface elements are pre-processed and projected onto a cylindrical surface, then display efficiency is improved and clutter is reduced, but the processing complexity increases
Solution Approach 1:
The patent applies preliminary action by pre-processing interface elements and projecting them onto a cylindrical surface before final display. This upfront transformation organizes all points of interest in a structured 3D coordinate system, enabling efficient rendering and reducing real-time processing demands. The pre-computed cylindrical projections allow the system to quickly display and update POIs as the user moves, improving overall display efficiency despite the initial processing investment.
