Tracking system

A myriad of tracking systems exists. Some are 'lag time' indicators, that is, the data is collected after an item has passed a point for example a bar code or choke point or gate.[1] Others are 'real-time' or 'near real-time' like Global Positioning Systems (GPS) depending on how often the data is refreshed. There are bar-code systems which require items to be scanned and automatic identification (RFID auto-id). For the most part, the tracking worlds are composed of discrete hardware and software systems for different applications. That is, bar-code systems are separate from Electronic Product Code (EPC) systems, GPS systems are separate from active real time locating systems or RTLS for example, a passive RFID system would be used in a warehouse to scan the boxes as they are loaded on a truck - then the truck itself is tracked on a different system using GPS with its own features and software.[2] The major technology “silos” in the supply chain are:

Regardless of the tracking technology, for the most part the end-users just want to locate themselves or wish to find points of interest. The reality is that there is no "one size fits all" solution with locating technology for all conditions and applications.

Application of tracking is a substantial basis for vehicle tracking in fleet management, asset management, individual navigation, social networking, or mobile resource management and more. Company, group or individual interests can benefit from more than one of the offered technologies depending on the context.

In virtual space technology, a tracking system is generally a system capable of rendering virtual space to a human observer while tracking the observer's coordinates. For instance, in dynamic virtual auditory space simulations, a head tracker provides information to a central processor in real time and this enables the processor to select what functions are necessary to give feedback to the user in relation to where they are positioned.[1]

Additionally, there is vision-based trajectory tracking, that uses a color and depth camera known as a KINECT sensor to track 3D position and movement. This technology can be used in traffic control, human-computer interface, video compression and robotics.[8]

Imagine a world where children all wear wristbands about the size of a Zippo lighter'-not as the newest fashion statement, but instead for security. These wristbands can transmit a signal with an effective range of over two football fields, narrowing down each child's position to within thirty feet. Furthermore, the system can track the children over a two square mile area surrounding their school. If a child walks off their path or does not make it to school on time, the centralized system automatically sends an e-mail or text message to the child's parents. ... In addition, cars near the children's school are fitted with the same technology, and if a vehicle drives near a child, a voice prompt will alert the driver ... While this scenario may seem fitting for the newest science fiction motion picture, the scene is reality in Yokohama City, Japan
