Dynamic Proximity Boundaries for Timely XR Object Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users interacting with immersive extended reality (XR) content may be distracted from their surrounding physical environment, leading to unawareness of nearby objects.
Innovation Solution
A system that dynamically generates proximity boundaries around the user or device based on velocity, detecting proximate objects within these boundaries and initiating notifications or modifying virtual content presentation to alert the user.

1Reliability
If a fixed proximity boundary is used to detect proximate objects, then the detection coverage is consistent, but the user may not be alerted in time when moving at high speed
Solution Approach 1:
The proximity boundary is dynamically adjusted based on the user's velocity. When the user moves faster, the boundary expands in the direction of motion to provide earlier warning of proximate objects. This dynamic adaptation ensures timely detection alerts while maintaining consistent coverage across varying motion conditions.
Solution Approach 2:
The system changes the spatial parameters of the proximity boundary according to the user's velocity magnitude and direction. The boundary's volume and orientation are modified as parameters respond to motion state, allowing the detection zone to scale with the user's movement characteristics.
2Loss of time
If the proximity boundary volume is increased to detect objects earlier, then the detection lead time increases, but the false alarm rate may increase
Solution Approach 1:
The proximity boundary applies different detection sensitivities to different spatial regions. The boundary volume is selectively expanded in the direction of user motion while maintaining more conservative boundaries in other directions. This localized quality adjustment provides earlier detection alerts in the motion direction without unnecessarily increasing false alarms in other areas.

AI summary
Providing a visual treatment based on proximity to an obstruction includes collecting, by a device, a sensor data for an environment, and determining a velocity of the device. A boundary of a volume around the device is determined based on the velocity. If a physical object is detected within the boundary based on the sensor data, then a notification procedure is initiated. The boundary of the volume dynamically changes as the velocity of the device or user changes.
