Static Navigation Display for Mobile AR Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In augmented reality navigation systems, users often deviate from the suggested path, making it difficult to maintain a static and recognizable navigation display, as existing systems continuously update the path based on the user's position and orientation, leading to irritation and disorientation.
Innovation Solution
A method and device that generate a static navigation display for a destination in a real environment, with adaptive updates based on user input or situational changes, such as dividing the environment into subareas and displaying supplementary navigation information like directional arrows or compasses, to minimize unnecessary path changes and maintain user orientation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the navigation path is continuously updated based on user position and orientation, then the navigation display adapts to user movement, but the path becomes unrecognizable and causes user irritation due to rapid changes
Solution Approach 1:
The navigation system implements dynamic path adaptation by dividing the environment into subareas and updating the navigation path only when the user transitions between subareas. This dynamic approach maintains path recognizability while adapting to user movement, resolving the contradiction between adaptability and stability.
Solution Approach 2:
The environment is segmented into multiple subareas, and the navigation path is updated discretely when users transition between these segments. This segmentation prevents continuous path changes, maintaining visual stability while still adapting to user position changes.
2Stability of the object's composition
If the navigation path is kept static for a fixed location, then the path remains recognizable, but it becomes indiscernible when users deviate from the path
Solution Approach 1:
The system dynamically adapts the navigation path based on user position within subareas. When users deviate from the static path, the system generates an adapted path that maintains recognizability while guiding users back to the correct route, resolving the contradiction between static recognizability and dynamic adaptability.
Solution Approach 2:
The navigation system continuously monitors user position relative to the navigation path and provides feedback by adapting the path display. When users deviate, the system adjusts the path to remain visible and guide users correctly, maintaining both recognizability and adaptability.
3Ease of operation
If the augmented reality display is updated at high refresh rate, then the display is interactive and responsive, but the continuously changing path distracts and irritates users
Solution Approach 1:
The navigation path is updated periodically when specific conditions are met (user transitions between subareas or significant position changes), rather than continuously at every frame. This periodic update approach maintains interactivity while reducing visual distraction and user irritation.
Solution Approach 2:
The system dynamically determines when path updates are necessary based on user behavior and position changes, updating the display only when meaningful navigation information needs to be conveyed. This maintains interactivity while minimizing unnecessary visual changes that cause distraction.

AI summary
The invention relates to a method, a device and a computer-readable storage medium with instructions for controlling a display of a mobile augmented reality device of a user. First a static navigation display for a destination is generated, which is positioned in a stationary manner in a real environment. If a situation is detected that requires an adaptation of the display of the mobile augmented reality device, a static navigation display adapted to the situation or a supplementary navigation display is generated.
