Dynamic personal extended reality safe area control
A personal safe area is determined for extended reality (XR) devices, such as head mounted devices in virtual reality (VR) sessions, sharing a common larger play area. The personal safe areas may be sized based on user size, may have radii centered on the XR device and parallel to a floor, and may move with the XR device as the XR device moves in an immersive reality session. A notification indicating proximity to another XR device may be generated, and the notification may indicate the direction from which the other XR device is approaching. Also contemplated is real time adjusting an XR gameplay, game display or game flow of one or more XR devices to avoid overlap of safe spaces by shifting virtual game objects in a safer direction.
1 . A method comprising:
determining a size of a first extended reality (XR) safe area for a first XR device based at least in part on an arm size of a user of the first XR device;
based at least in part on detecting movement of the first XR device, moving the first XR safe area with the first XR device; and
based at least in part on detecting a proximity of the first XR safe area to a second XR safe area of a second XR device, transmitting to the first XR device a notification indicating the proximity.
2 . The method of claim 1 ,
wherein the first XR device is a head mounted device, and wherein the first XR safe area has a circular shape with radii centered at the first XR device and parallel to a floor.
3 . The method of claim 1 , wherein the first XR safe area and the second XR safe area are located in a common demarcated play area of a virtual reality session, and further comprising:
based at least in part on detecting the movement of the first XR device, repositioning the first XR safe area so that the first XR safe area has radii centered at the first XR device and parallel to a floor; and
notifying the first XR device when the first XR safe area intersects a boundary of the common demarcated play area.
4 . The method of claim 1 , further comprising:
based at least in part on detecting the movement of the first XR device in a virtual reality session, repositioning the first XR safe area such that the first XR safe area has radii centered at the first XR device and parallel to a floor;
wherein the detecting of the proximity of the first XR safe area to the second XR safe area comprises determining that that the first XR device has recently moved toward the second XR device; and
based at least in part on the detecting of the proximity of the first XR safe area to the second XR safe area, transmitting to the second XR device a second notification indicating the proximity.
5 . The method of claim 4 , wherein the second notification appears different on the second XR device than the notification on the first XR device.
6 . A system comprising:
processing circuitry configured:
to determine a size of a first extended reality (XR) safe area of a first XR device based at least in part on an arm size of a user of the first XR device; and
based at least in part on detecting movement of the first XR device, moving the first XR safe area with the first XR device; and
communication circuitry configured:
to transmit to the first XR device, based at least in part on detecting a proximity of the first XR safe area to a second XR safe area of a second XR device, a notification indicating the proximity.
7 . The system of claim 6 , wherein the first XR device is a head mounted device, and wherein the first XR safe area has a circular shape with radii centered at the first XR device and parallel to a floor.
8 . The system of claim 6 , wherein the first XR safe area and the second XR safe area are located in a common demarcated play area of a virtual reality session, and wherein the processing circuitry is further configured:
to reposition, based at least in part on detecting the movement of the first XR device, the first XR safe area so that the first XR safe area has radii centered at the first XR device and parallel to a floor; and
to notify the first XR device when the first XR safe area intersects a boundary of the common demarcated play area.
9 . The system of claim 6 , wherein the processing circuitry is further configured:
to reposition, based at least in part on detecting the movement of the first XR device in a virtual reality session, the first XR safe area such that the first XR safe area has radii centered at the first XR device and parallel to a floor;
wherein the detecting of the proximity of the first XR safe area to the second XR safe area comprises determining that that the first XR device has recently moved toward the second XR device; and
to transmit, based at least in part on the detecting of the proximity of the first XR safe area to the second XR safe area, to the second XR device a second notification indicating the proximity.
10 . The system of claim 9 , wherein the second notification appears different on the second XR device than the notification on the first XR device.
11 . The system of claim 6 , wherein the determining the size of the first XR safe area comprises determining a distance from a first distal extent of a first extended arm of the user of the first XR device to a second distal extent of a second extended arm of the user of the first XR device.
12 . The system of claim 6 , wherein the determining the size of the first XR safe area comprises determining a distance from a first position of a first hand-held XR device held by the user of the first XR device to a second position of a second hand-held XR device held by the user of the first XR device.
13 . The system of claim 6 , wherein the first XR device is a head mounted device worn on a head of the user of the first XR device, wherein the determining the size of the first XR safe area comprises determining a distance from the head mounted device to a first position of a hand-held XR device held by the user of the first XR device.
14 . The method of claim 1 , wherein the determining the size of the first XR safe area comprises determining a distance from a first distal extent of a first extended arm of the user of the first XR device to a second distal extent of a second extended arm of the user of the first XR device.
15 . The method of claim 1 , wherein the determining the size of the first XR safe area comprises determining a distance from a first position of a first hand-held XR device held by the user of the first XR device to a second position of a second hand-held XR device held by the user of the first XR device.
16 . The method of claim 1 , wherein the first XR device is a head mounted device worn on a head of the user of the first XR device, wherein the determining the size of the first XR safe area comprises determining a distance from the head mounted device to a first position of a hand-held XR device held by the user of the first XR device.
