This process/mechanism is known as an alert. For alert creation users edit an XML file. In phase II, Users will be able to create, modify, and delete alerts from within the Tentacle Client user interface. As an example of an alert, a user might wish to be automatically notified if an entity of interest (person XYZ or a vehicle of a particular color) appears to the system, or appears within a particular geographic region. Tentacle Plugin will then send the alert construct to Tentacle Server, which will continuously monitor the TIPL and will construct asynchronous notifications to send to Tentacle Client. These asynchronous notifications will appear visually distinct to the user, thus allowing appropriate action to be taken. 2.14.4 Example Tentacle System Operational Scenario As an example of how Tentacle System might ultimately function, consider a simple instance consisting of one Tentacle Mote, one Tentacle Client, and the requisite Tentacle Server. First, Tentacle Server is started and begins listening for connections from both Tentacle Motes and Tentacle Clients. Next, Tentacle Mote connects and begins streaming live video and metadata, which is archived by TIPL. Next, a User starts a Tentacle Client, which connects to Tentacle Server and immediately begins receiving the T2DL data feed. The user interface displays the 36 Distribution A: Approved for public release; distribution unlimited. 88ABW/PA Cleared 02-16-12; 88ABW-2012-0850
location of each battlefield entity described by the T2DL feed, which ultimately originates from the entities being tracked by Tentacle Mote. Within the Tentacle Client user interface, these entities may appear as realistic-looking 3d avatars overlaid on high-resolution imagery in NASA WorldWind. The user may then observe battlefield happenings and drill down on interesting events. Specifically, the user may see an entity of interest, and quickly pull up the live video feed from the sensor platform performing the capture. The user may also perform a query of the TIPL to determine when and where that particular entity was last seen, and view the actual video clip of the entity at that time. This example operational scenario illustrates how Tentacle System might assist Air Force operations. 2.15 Transitioned from Google Earth to NASA WorldWind In Tentacle Client, we transitioned from a Google Earth based GUI to one based on NASA WorldWind. Technically speaking, Tentacle Client is now a Java application that has a dependency on the NASA WorldWind Java SDK. Tentacle Client uses the WorldWind SDK’s functionality for displaying a 3D map with high-resolution imagery and point/line/area overlays. However, Tentacle Client also includes network communications code to communicate with Tentacle Server, and code to manage the display, location, and appearance of entities presented in the WorldWind window. One technical note: during the migration to NASA WorldWind, we discovered that there are actually two major SDKs for NASA WorldWind, one for the Microsoft .NET framework and one for Java. Initially we integrated with the Microsoft .NET version. However, we quickly discovered that the Microsoft .NET version of the WorldWind SDK contained several glitches that would severely hamper our ability to proceed with development of Tentacle Client. In trying to get support for the Microsoft .NET version of the WorldWind SDK, we discovered that it had been largely abandoned by the open source community in favor of the Java version sometime in 2010. We found evidence of this in many ways, including more activity on Java forums and more recent commit dates for the Java SDK source code. 2.16 Upgraded to intuVision Panoptes SDK 3.7 We upgraded to a new version of the intuVision Panoptes SDK, version 3.7. For this release, intuVision incorporated: The ability to classify a tracked object as either a person, vehicle, or unknown The ability to detect the upper (shirt) color of a person being tracked The ability to detect the lower (pants/shorts) color of a person being tracked This classification and color data is then packaged along with intuVisionObjects produced by the Panoptes SDK. The result is that Tentacle Mote can now publish metadata for tracked entities including entity type, upper color, lower color, position, and time. Figure 20 provides an example of how Panoptes tags the shirt and pant color of people in video as metadata. 37 Distribution A: Approved for public release; distribution unlimited. 88ABW/PA Cleared 02-16-12; 88ABW-2012-0850
