Abstract: A method is outlined for controlling a node to a join a wireless network, which increases the speed of the wireless network commissioning procedure by reducing the chance of congestion. This is achieved by differentiating the joining time of nodes attempting to join the wireless network. Nodes indirectly communicate by transmitting beacon request messages to nodes of the wireless network, which results in the transmission of beacon messages by nodes of the wireless network. These beacon messages can be received by all nodes attempting to join the wireless network. Therefore, the beacon messages can be utilized as an indicator for nodes attempting to join the wireless network as to the number of other nodes attempting to join the wireless network. Based on this indication, the node can be controlled to wait for a further length of time, or to join the wireless network.

Abstract: Aspects of the present disclosure are directed to creating interactive avatars that can be pinned as world-locked artificial reality content. Once pinned, an avatar can interact with the environment according to contextual queues and rules, without active control by the avatar owner. An interactive avatar system can configure the avatar with action rules, visual elements, and settings based on user selections. Once an avatar is configured and pinned to a location by an avatar owner, when other XR devices are at that location, a central system can provide the avatar (with its configurations) to the other XR device. This allows a user of that other XR device to discover and interact with the avatar according to the configurations established by the avatar owner.
