Solution Overview

Problem

Image-based navigation systems often fail to draw users' attention to points of interest due to their orientation within the simulated field of view, especially in dense urban areas, leading to missed or unnoticed landmarks and advertisements during virtual navigation.

Innovation Solution

The system adjusts the orientation of the simulated field of view and points of interest to ensure they are optimally visible, using techniques such as reorientation, scaling, and alteration of perspective to maintain focus on key points, and incorporates user profiles and sponsor compensation to direct attention effectively.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the simulated field of view is oriented in the direction of travel, then the user can see the route ahead, but points of interest may lie outside the field of view and be missed

Engineering Contradiction:
Improveroute navigationVSAvoidpoints of interest visibility
Core Design Contradiction:
Ease of operationVSLoss of information

Solution Approach 1:

The system dynamically adjusts the simulated field of view orientation based on the user's position relative to points of interest. When a point of interest is detected within a certain distance, the field of view is rotated to face it, creating a dynamic switching behavior between route-following mode and point-of-interest-focused mode

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system introduces an intermediary mechanism that detects points of interest and mediates between the user's navigation direction and the optimal viewing direction for points of interest, using distance thresholds and orientation calculations to determine when to shift focus

Inventive Principle:
Principle #24Intermediary (Mediator)

2Loss of information

If the field of view is widened to capture more points of interest, then more landmarks become visible, but visual details become obscured or indistinguishable

Engineering Contradiction:
Improvepoints of interest coverageVSAvoidvisual detail clarity
Core Design Contradiction:
Loss of informationVSMeasurement precision

Solution Approach 1:

The field of view width is dynamically adjusted based on the user's proximity to points of interest. When approaching a point of interest, the system narrows the field of view to concentrate on it, and widens it when moving between points of interest to maintain awareness of the surroundings

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system applies different field of view characteristics to different spatial regions: a narrow, high-detail central view for the immediate point of interest and a wider peripheral view for contextual landmarks, creating local quality variations in visual information presentation

Inventive Principle:
Principle #3Local quality

3Loss of information

If the system presents all visual information from the image dataset, then complete geographic context is provided, but the sheer volume of visual information overwhelms the user

Engineering Contradiction:
Improvegeographic contextVSAvoidvisual information processing
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The system extracts and highlights only the most relevant points of interest from the complete image dataset, filtering out extraneous visual information. It uses distance thresholds and orientation calculations to selectively present only those points of interest that are currently relevant to the user's navigation

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

Different levels of visual information density are applied to different regions: high-detail presentation for the current point of interest and reduced-detail presentation for distant or less relevant landmarks, creating a hierarchical information structure

Inventive Principle:
Principle #3Local quality

AI summary

Manipulation of a user's attention is disclosed with respect to a point of interest represented in a simulated field of view of a geographic locality during simulation of travel between locations therein, such as by a computer-implemented navigation system or application. As a user virtually navigates a route, the simulated field of view presented on a display thereto may be constrained, immediately or gradually to an orientation, different from the direction of travel or otherwise from an orientation selected by the user, which focuses on, or otherwise includes the point of interest, or a representation thereof. In this manner, the user's attention is directed or otherwise drawn to the point of interest, e.g. they are less likely to miss or ignore it.
