Virtual Reality Field of View Segmentation for Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
User interactions in virtual and augmented reality environments lack haptic feedback and intuitive navigation due to the absence of physical device visibility and immersion, making it difficult to interact with virtual objects and move digital content effectively.
Innovation Solution
A computing device detects physical interactions with devices like keyboards and mice, generating digital content to represent these interactions and provide haptic feedback, while employing a world relative field of view to follow user motion and a fixed relative field of view to maintain digital content visibility during navigation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If virtual reality creates an immersive environment where the entire user's view is generated by digital content, then the richness of the user experience is expanded, but the user may be unable to differentiate between virtual objects and physical objects, and navigation becomes difficult
Solution Approach 1:
The field of view is segmented into a fixed relative field of view and a world relative field of view. The fixed relative field of view contains navigation aids and digital content that remain stable, while the world relative field of view provides the immersive virtual reality experience that moves with the user's head motion.
Solution Approach 2:
A fixed relative field of view acts as an intermediary between the user and the immersive virtual environment, providing stable reference points and navigation aids that help the user orient themselves without breaking the immersion of the virtual reality experience.
2Adaptability or versatility
If augmented reality overlays digital content on the physical environment, then the user can see what is actually there while enhanced with virtual objects, but the user is not provided with haptic feedback regarding interaction with virtual objects
Solution Approach 1:
The fixed relative field of view serves as an intermediary that provides stable reference points and navigation aids, helping the user understand their position and orientation in the augmented reality environment, which compensates for the lack of haptic feedback in virtual object interactions.
3Adaptability or versatility
If the virtual reality environment is configured as immersive (360-degree view), then the user experience richness is expanded, but it becomes difficult to navigate and move digital content using conventional techniques
Solution Approach 1:
The display is segmented into two distinct fields of view: a fixed relative field of view that remains stable and contains navigation controls and digital content, and a world relative field of view that provides the 360-degree immersive experience. This segmentation allows both immersive viewing and easy navigation to coexist.
Solution Approach 2:
The navigation interface is moved from the traditional full-screen immersive view to a separate fixed relative field of view dimension, allowing users to navigate and interact with digital content without leaving the immersive 360-degree environment. This adds a new dimensional layer to the user interface.

AI summary
Digital content interaction and navigation techniques and systems in virtual and augmented reality are described. In one example, techniques are employed to aid user interaction within a physical environment in which the user is disposed while viewing a virtual or augmented reality environment. In another example, techniques are described to support a world relative field of view and a fixed relative field of view. The world relative field of view is configured to follow motion of the user (e.g., movement of the user's head or mobile phone) within the environment to support navigation to different locations within the environment. The fixed relative field of view is configured to remain fixed during this navigation such that digital content disposed in this field of view remains at that relative location to a user's field of view.
