TECHNIQUES FOR COORDINATING DEVICE ACTIVITY

原文（中文）

Some techniques are described herein for coordinating device activity, with devices included in one or more different groups of devices. One technique includes coordinating activities among a group as coordinator. For example, in a group of devices, a coordinator device obtains a cluster list of activities from each member device in the group. The coordinator device establishes a new cluster list of activities based on each received cluster list of activities and sends the new cluster list to the member devices. Another technique includes coordinating changes of the coordinator role as a member. Another technique includes changing state of activities via an assertion system. Another technique includes selectively sending requests to change states of local activities. Yet another technique includes a distributed mechanism for selecting a primary device to interact with a user.
