Tracking means tracking or following. In the context of ITWissen, the term tracking is used in connection with the determination and tracking of the position of persons and goods, but also with the analysis of user behavior on the web and with the optimization of websites by means of mouse tracking, attention tracking and eye tracking.
and tracing of goodsWhile location tracking is about determining the position of people, objects, goods and merchandise, tracking and tracing is about locating and tracing moving goods. For example, location tracking can be used to locate a shipping container in a container port, a piece of equipment within a company or hospital, or to coordinate fleet management. Tracking has completely different requirements for location accuracy, which are directly related to the size of the objects and the area to be monitored. A seaport makes different demands on the infrastructure and the location of objects than a small warehouse.
Tracking with GSM modules and RFID tagsIn the context discussed here, the focus is on radio technologies that can be used to locate products. However, radio technology requires that the object being searched for can be detected by radio technology. This requirement can only be met if the object to be located has a radio-technical behavior, i.e. either a GSM module, its own transmitter or a resonant circuit. GPS tracking can work with GPS loggers or GPS trackers whose GPS data is transmitted by a GSM module or with an RFID tag. As for RFID technology, devices can be or are equipped with RFID tags. With this simple equipment, it is at least possible to determine whether an object with a tag has passed through a detection gate and thus changed its previous position. Since RFID tags only work in the immediate vicinity of the detection device, WiFi tags are used for greater distances. These use only the ISM band at 2.4 GHz, in which WLANs also operate. The position is determined by detecting the differences in propagation time between the WiFi tag and the various access points (APs). The signals arriving at the access points are given a time stamp that forms the basis for calculating the position. The position accuracy depends on the number and distance of the access points and is around three meters outdoors and around one meter indoors. Another method relies on the received signal strength and evaluates it: Received Signal Strength Indicator( RSSI). In addition, the real-time locationsystem ( RTLS) is a technology that works with active RFID tags.
Web tracking around user movementsOn the web, web tracking refers to user tracking. This is used to document user movements on the Internet. Internet tracking is done via the referrer, a reference in the header of the HTTP protocol to the last Internet address( URL) visited. The referrer identifies the Internet address from the website from which the user clicked to another website via an inbound link. Internet addresses stored in a log file can be used to determine which website a user was on before accessing another website. From web tracking or web analytics, one can determine the user's interests and behavior through web usage mining. Other tracking methods that focus attention are eye tracking and attention tracking, another that involves people's movement profiles is motion capture.
