HMD Notification Display for External Object Awareness in AR/VR
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users wearing head-mounted displays (HMDs) may lose awareness of external objects due to focusing on augmented or virtual reality content, increasing the risk of accidents.
Innovation Solution
An electronic device with sensors and processors that prioritize the display of augmented or virtual reality content based on the importance of external objects, adjusting the size and presence of indicators to ensure user awareness, and providing additional notifications through sound and haptic feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If augmented reality objects or virtual reality objects are displayed in the first area, then user immersion in virtual content is improved, but user awareness of external objects deteriorates
Solution Approach 1:
The system dynamically adjusts the display configuration based on the importance of external objects. When an external object is detected with high importance (e.g., dangerous object approaching), the system removes or reduces the display of augmented reality objects in the first area and displays a warning indicator in the second area. When external objects have low importance, the system restores the augmented reality objects for user immersion. This dynamic switching resolves the contradiction by adapting the virtual content display to the safety requirements of the external environment.
2Reliability
If indicator size is increased to improve external object visibility, then user awareness of external objects is improved, but display area for augmented reality objects is reduced
Solution Approach 1:
The system utilizes the second area (peripheral area) of the display for displaying warning indicators when external objects are detected, rather than expanding indicators in the first area which would compete with augmented reality objects. This spatial separation in different display areas allows both functions to coexist: the first area maintains augmented reality content while the second area provides external object warnings, resolving the area conflict.
3Reliability
If augmented reality objects are removed to improve external object recognition, then user awareness of external objects is improved, but user immersion in virtual content is reduced
Solution Approach 1:
The system performs preliminary detection of external objects using sensors before they become a safety hazard. When a dangerous external object is detected in advance, the system proactively removes or reduces augmented reality objects and displays warning indicators, preventing the safety issue before it occurs. This preliminary action allows the system to minimize immersion loss while maximizing safety awareness by only reducing virtual content when actually needed.

AI summary
An electronic having a sensor, a display including a first area and a second area, and a processor electrically connected to the sensor and the display. The processor acquires information on an external object through the sensor, determines the importance of the external object through the information, and controls the display to display at least one augmented reality object or at least one virtual reality object in the first area in response to at least one of determining that the importance is less than a first importance and that the information on the external object has not been acquired. The processor also controls the display to display an indicator in the second area so that the indicator has a first size and removes at least a part of the at least one augmented reality object or the at least one virtual reality object according to priorities.
