Adaptive VR Content Positioning for Non-Upright HMD Use
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current head-mountable display (HMD) technology lacks a specialized user interface framework for both virtual reality (VR) and augmented reality (AR) applications, particularly failing to adapt effectively when the user transitions to non-upright positions.
Innovation Solution
The implementation of a body position-sensitive virtual reality system for HMDs, which generates and adjusts the display of user interface content based on changes in the user's orientation, ensuring that the content remains within the viewable range and responds naturally to head motions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If HMD technology focuses on VR situations when the user is sitting upright, then the user interface is optimized for upright positioning, but the system fails to adapt when the user transitions to non-upright positions
Solution Approach 1:
The system dynamically adjusts the virtual environment and UI element positions based on real-time detection of user body orientation. The processor continuously monitors orientation data from sensors and repositions content elements accordingly, transforming the static UI framework into a dynamic adaptive system that responds to user position changes.
Solution Approach 2:
The system changes spatial parameters of displayed content based on detected user orientation. When non-upright positions are detected, the system modifies the position, orientation, and sometimes the layout parameters of UI elements to ensure they remain within the user's viewable range and are easily accessible.
2Ease of operation
If content is displayed at a fixed default position in the viewable range, then the display setup is simple, but the content becomes inaccessible or difficult to view when user orientation changes
Solution Approach 1:
The system implements a feedback loop where sensors continuously detect user orientation and provide data to the processor, which then adjusts content positioning accordingly. This closed-loop feedback mechanism ensures content remains accessible without requiring complex manual adjustment mechanisms.
Solution Approach 2:
The system automatically repositions content based on detected user orientation without requiring user intervention. The processor autonomously calculates and applies position adjustments to UI elements, making the system self-adjusting and eliminating the need for complex manual control mechanisms.
3Adaptability or versatility
If the user interface framework is designed for upright sitting positions, then development is simplified, but the system lacks versatility for various body positions such as lying down or reclining
Solution Approach 1:
The system creates a universal UI framework that functions across multiple body positions (upright, reclining, lying down, etc.). By detecting orientation and automatically adapting the display, a single UI framework serves multiple functions and positions, eliminating the need for separate frameworks for each posture.
Solution Approach 2:
The UI framework transitions from a static design optimized for one position to a dynamic framework that automatically reconfigures based on detected user orientation. This dynamic adaptation allows the same framework to serve multiple positions without requiring developers to create separate UI designs for each posture.

AI summary
An apparatus is provided for displaying a user interface (UI). The apparatus includes a head-mountable display (HMD) and at least one processor configured. The processor is configured to generate content for display by the HMD at a default position in a viewable range, the viewable range including a viewed region that is visible to a user while wearing the HMD. The processor is also configured to, responsive to a change in orientation of the HDM, identify a new default position for the content in the viewable range based on the change in the orientation. The processor is also configured to display the content at the new default position in the viewable range when the new default position is within the viewed region.
