Abstract: The disclosed computer-implemented method may include receiving, from devices in an environment, real-time data associated with the environment and determining, from the real-time data, current object data for the environment. The current object data may include both state data and relationship data for objects in the environment. The method may also include determining object deltas between the current object data and prior object data from an event graph. The prior object data may include prior state data and prior relationship data for the objects. The method may include detecting an unknown state for one of the objects, inferring a state for the object based on the event graph, and updating the event graph based on the object deltas and the inferred state. The method may further include sending updated event graph data to the devices. Various other methods, systems, and computer-readable media are also disclosed.

Abstract: Exemplary embodiments relate to improvements in the design of a messaging inbox. The inbox may display different units or “modules” for providing a user with quick access to different inbox functionalities that they might not otherwise be aware of (or inclined to use on a regular basis). After a number of recent or unread messages are shown in the inbox's initial interface, the messages end and are replaced with modules. Many different types of functionality may be the subject of the modules (e.g., a module for sharing local content such as photos from a photo album, a People/States module, Top Contacts, New Behavior, Live Videos, Events, Businesses, or Messaging Stickers). Once the available modules have been scrolled through, the interface may revert to more messages, such as less-recent or previously read threads from the original messages. Unread threads may also be collapsed in the top section of the inbox, or included in a module.
