Abstract: In implementations of a hub coordination service, a device includes a communication interface for communication coordination with one or more associated devices of the device, and the associated devices correspond to hub members. A hub manager is implemented to receive a task input to create a task for one or more of the hub members to complete. The hub manager can register the task in a hub that is a private, shared space of the hub members, and then initiate communication of the task to respective associated devices of the one or more hub members for notification of the task to be completed.

Abstract: Mobile device emergency service techniques are described. In embodiments, a client device includes one or more modules implemented at least partially in hardware and configured to implement an emergency service. The emergency service configured to support operations including generating a user interface for display on a display device, receiving one or more inputs usable to form an emergency contacts list that includes a plurality of emergency contacts, and causing the emergency contacts list to be communicated to one or more other client devices for use in generating a message to be communicated automatically and without user intervention to the emergency contacts in the emergency contacts list responsive to a trigger.

Abstract: In embodiments of private interaction hubs, a mobile device has memory storage to maintain hub data that is associated with a private interaction hub, where the hub data includes multiple types of displayable data that is editable by different types of device applications. The memory storage at the device also maintains private data that is displayable and is viewable with one of the device applications. The mobile device also includes a display device to display the multiple types of the hub data in a hub user interface of a hub application. The display device can also display the private data and a subset of the hub data that are both associated with a device application in a device application user interface.
