Patent number: 12167780Abstract: A necklace manager of an interactive necklace can sense user conditions and transmit messages to recipient computing devices. The necklace manager can compare sensed user conditions from the interactive necklace sensors to predefined user condition templates to determine a match. The matching predefined user condition template can be mapped to a user intent. The necklace manager can, in response to mapping the sensed user conditions to the user intent, transmit a message to a recipient device that is based on the mapped user intent and a user identifier. In some implementations, the recipient device can be an other interactive necklace that performs a mapped interactive necklace action in response to the received message. For example, a wearer of the recipient interactive necklace can perceive sentiments, emotions, and/or reactions from a user wearing the originating interactive necklace by perceiving interactive necklace actions triggered by the received message.Type: GrantFiled: December 20, 2022Date of Patent: December 17, 2024Assignee: Meta Platforms Technologies, LLCInventors: Charlene Mary Atlas, Nadine Sharon Anglin, Auset Parris

Patent number: 12164741Abstract: A user uses “snap points” to activate virtual objects and/or to transition virtual objects from body-locked or head-locked (i.e., “leashed”) to world-locked. A snap point is a specific location in the user's artificial-reality (XR) world. When the user assumes a position near to where he was when he previously defined a snap point, the object ceases to be leashed and instead locks to the snap point (i.e., the object becomes “world-locked”). Until the user's distance from where he was when he defined the snap point exceeds a threshold value, the object remains stably world-locked at the snap point. When the user moves more than the threshold, the object releases from the snap point, returns to its previously defined leashed mode, and follows the user through the XR world as previously.Type: GrantFiled: April 11, 2022Date of Patent: December 10, 2024Assignee: Meta Platforms Technologies, LLCInventors: Camila Cortes De Almeida E De Vincenzo, Hayden Schoen

Patent number: 12146965Abstract: A depth camera assembly (DCA) includes a direct time of flight system for determining depth information for a local area. The DCA includes an illumination source, a camera, and a controller. The illumination source projects light (e.g., pulse of light) into the local area. The camera detects reflections of the projected light from objects in the local area. Using an internal gating selection procedure, the controller selects a gate window that is likely to be associated with reflection of a pulse of light from an object. The selected gate may be used for depth determination. The internal gating selection procedures may be achieved through external target location and selection or through internal self-selection.Type: GrantFiled: January 24, 2023Date of Patent: November 19, 2024Assignee: Meta Platforms Technologies, LLCInventors: Augusto Ronchini Ximenes, Michael Hall
