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.

Abstract: In a power factor correction PFC circuit control method and a PFC circuit, a control module determines that an alternating current on a single-phase input/output terminal is in a positive half cycle. The control module turns on or turns off switching transistors on the first bridge arm and the second bridge arm, to boost a first voltage at a first parallel connection point. The control module turns on a switching transistor on the third bridge arm when determining that the first voltage is equal to a voltage of a positive bus of the direct current module. A switching loss of the PFC circuit can be effectively reduced, and performance of the PFC circuit can be improved.
