20140368333 | VARIABLE NOTIFICATION ALERTS - Approaches in accordance with various embodiments attempt to provide a user with less disruptive event notifications by being aware of a user's context. Before a notification is sent to multiple computing devices associated with the notifying account, contextual information for each device is determined. The contextual information can be determined by querying each device for information. The information can include how close each device is relative to other devices associated with the same user, if at least one of the devices is moving, whether the user's attention is focused on a particular device, whether the user is engaging multiple devices simultaneously, and the like. Once contextual information associated with each device is determined, an appropriate type of alert associated with the notification is determined for each device. Accordingly, upon determining the appropriate alert for the most probable context of each device, the notification is sent to each computing device with the determined appropriate type of alert. | 12-18-2014 |
