AR Device GUI Placement Avoiding Dangerous Objects
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Augmented reality devices struggle to accurately display graphical user interfaces (GUIs) for controlling content due to visual confusion between real and virtual objects, often causing GUIs to be displayed on dangerous objects or in inaccessible locations, leading to user inconvenience and potential injury.
Innovation Solution
An augmented reality device method and system that captures spatial and identification information of surrounding objects, determines the presence of dangerous objects within a preset distance, and displays a first GUI for content control within a safe distance and a second GUI for content display at a greater distance, using a camera, processor, and SLAM technology to prevent GUIs from being displayed on hazardous objects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the augmented reality device displays GUI for controlling content at a location determined by SLAM technology, then the GUI can be displayed in the physical environment space, but the GUI may be displayed on dangerous objects or in inaccessible locations causing user injury or inconvenience
Solution Approach 1:
The system performs preliminary identification of dangerous objects and inaccessible locations before displaying the GUI. By pre-mapping the environment using SLAM and pre-identifying hazardous areas, the system prevents GUI placement in dangerous locations before the user interacts with the content, thereby avoiding potential injuries.
Solution Approach 2:
The system introduces an intermediary safety verification mechanism between the GUI display location selection and the actual rendering. This intermediary layer checks whether the selected location is safe by comparing it against the pre-identified dangerous objects and inaccessible areas, allowing the system to adjust or relocate the GUI to safe positions.
2Adaptability or versatility
If the augmented reality device uses SLAM technology to recognize space, then the virtual image can be projected onto physical environmental space, but the device cannot accurately distinguish surrounding objects causing visual confusion between real and augmented objects
Solution Approach 1:
The system segments the spatial environment into distinct functional zones: safe display areas, dangerous object locations, and inaccessible areas. By dividing the continuous physical space into discrete categorized regions, the system can accurately distinguish and differentiate between various types of objects and spaces, preventing visual confusion between real and augmented elements.
3Illumination intensity
If the GUI is displayed inside a wall, inside a desk, or through a real object, then the user can check the GUI visually, but the user cannot operate the GUI due to physical limitations
Solution Approach 1:
The system performs preliminary verification of both visibility and operability before displaying the GUI. By pre-checking whether the selected location allows both visual access and physical interaction, the system avoids placing GUIs in locations where users can see but cannot operate the controls, ensuring both visibility and ease of operation are satisfied.

AI summary
A method and a device are provided. The method includes obtaining spatial information of objects surrounding an augmented reality device, obtaining identification information of the surrounding objects, determining, based on the spatial information and the identification information of the surrounding objects, whether there is, among the surrounding objects, a dangerous object within a preset distance from the augmented reality device, and based on the determining, displaying, within a first distance from the augmented reality device, a first graphical user interface (GUI) for controlling reproduction of the content to be displayed through augmented reality technology, and displaying, within a second distance from the augmented reality device, a second GUI for displaying the content.
